All New Saab 9-3 Highlights:

Sporty handling to challenge class benchmark
Saab �ReAxs� - unique rear wheel steer characteristic
Braking system includes CBC and EBD
Excellent steering and chassis response
�Best in Class�, Saab-tuned ESP

 

The all new Saab 9-3 fulfils its role as a �fun to drive� sport sedan by displaying exceptional handling characteristics that not only set new standards for Saab but also promise to set a new class benchmark.

It is the result of a rigorous development program, the most exhaustive ever undertaken by Saab, designed to combine the benefits of front wheel drive � predictability and excellent driver feedback � with new levels of chassis control for a more rewarding driving experience.

The all new 9-3�s exceptionally stiff body and all-new suspension provided Saab test drivers with a solid foundation on which to achieve outstanding chassis dynamics, exemplary ride refinement and impressively low levels of noise, vibration and harshness.

The chassis�s innate talents are backed up with a full arsenal of electronic driver aids, including ABS (Anti-lock Braking System), TCS (Traction Control System), EBD (Electronic Brake force Distribution), CBC (Cornering Brake Control) and ESP (Electronic Stability Programme) � items that are standard on all models sold in Australia and New Zealand.

Sporty Handling
The top priority of the all new 9-3�s chassis development program was to achieve best-in-class handling characteristics. This was an essential requirement as the car is targeted at drivers whose priority is a satisfying, performance orientated driving experience. Saab�s chassis engineers are confident that anyone who drives the all new 9-3 will immediately appreciate its quick responses to steering, throttle and braking inputs, together with its impressive levels of grip, driver feedback and body control.

Saab�s own benchmarking process and the findings of comparison tests with competitor cars carried out by an independent agency confirm that the all new 9-3�s driving dynamics place it at the top if its class.

Compared to the old 9-3, the key dimensions of the new car offer considerable scope for improvements in handling and grip. The front and rear tracks, at 1524 mm and 1506 mm respectively, are 74 mm and 63 mm wider. Combined with a 70 mm increase in wheelbase, a 10 mm reduction in ride height, a lower centre of gravity and an inherently stiffer sedan bodyshell, the dynamics of the new chassis are more competent in every respect.

�ReAxs� � passive rear wheel steer

The adoption of a four-link rear suspension layout has allowed engineers to dial in a unique, passive rear wheel steer characteristic (Saab �ReAxs�) by carefully tuning both inboard and outboard suspension bushings.

When cornering, the kinetics at the rear axle induce a very slight deflection of both rear wheels in the opposite direction to the steering input, ie. toe-out for the outer wheel and toe-in for the inner wheel.

Depending on the radius of the bend and the consequent loadings at the rear axle, one degree of movement at the front wheels would typically produce a small but significant response of about one hundredth of a degree at the rear.

This is sufficient to prevent excessive understeer, where the driver is forced to apply progressively more steering lock to turn the front end of the car, increasing the scrub angles of the front tyres. The �ReAxs� characteristic overcomes this �crabbing� effect, helping the tail of the car follow the direction of the front wheels, instead of its nose. For the driver, this gives the car better balance, helping it turn in and respond more closely to steering inputs.

Suspension Design

The front suspension is by MacPherson struts with de-coupled top mountings, separating the damper and spring loadings. The lower control arms are attached to a hydroformed (hollow section) front sub-frame, including a hydraulic bush on the rearmost mounting each side for optimum damping. The layout is designed to be largely impervious to lateral forces and compliant longitudinally for good directional stability and ride comfort.

The independent rear suspension is also mounted on a sub-frame and incorporates three transverse and one longitudinal link. Compared to the rigid torsion beam used for the previous model, the new layout has far more longitudinal compliance. Like the front suspension, bushings are stiff for lateral forces and relatively soft longitudinally. The new suspension allows greater scope for optimising both handling and ride characteristics, as well as helping to prevent road noise entering the cabin.

New for Saab is the adoption of shear bushings for the top mountings in the rear shock absorbers. These effectively dissipate vibration from the road by absorbing small longitudinal movements before they are transmitted directly into the mounting and the structure of the car. This feature improves ride quality and also plays an important role in further attenuating road noise.

Reducing Unsprung Weight

All four wheel carriers (hubs) and brake calipers, lower control arms in the front suspension and the toe and lower links in the rear suspension are made from aluminium. This minimises unsprung weight and delivers the high standard of ride quality expected in this class of car.

Elsewhere, weight-saving materials are used wherever stiffness is not compromised. Both front and rear anti-roll bars and the shock absorber piston rods are made from hollow section steel.

Braking System

The powerful steel disc brakes (ventilated at the front) are always a match for the performance of the new 9-3 and disc size is specified according to engine power. For the 110 kW Linear there are 283 mm front and 276 mm rear discs. For 129 kW Arc and Vector these are 300 mm at the front and 290 mm at the rear. And for the 155 kW Aero there are even larger 312 mm front discs.

High speed braking stability sets new standards for Saab thanks to the ReAxs control of the rear suspension geometry. This effectively �preloads� the rear tyres by applying some lateral force through toe-in as braking commences.

An automatic brake boost feature, Mechanical Brake Assist, is introduced for the first time. This increases braking pressure from the master cylinder when the driver stamps hard on the brake pedal, stopping the vehicle quicker, and coming into play ahead of the car�s ABS.

A four channel ABS (Anti-lock Braking System) and a TCS (Traction Control System), with additional throttle control, is standard fitment for all variants. A series of electronic brake control functions also utilise the ABS wheel speed sensors and variable valving at each wheel.

EBD (Electronic Brake force Distribution) ensures optimum braking force is always applied at both axles for maximum stability under heavy braking, and again, is standard fitment on all models.

New for Saab is the introduction of CBC (Corning Brake Control), which is activated when the car is cornering under heavy braking. Brake pressure is individually varied between all four wheels so as to keep the car stable, minimising any snap oversteer or understeer characteristics. CBC is also standard on all models.

All four brake discs have full size dust shields. These ensure braking performance is not impaired by large amounts of snow, mud or dust jamming the calipers.

Precise Steering

The power steering on Saab cars is widely acknowledged for achieving just the right balance between assistance and �feel�. In the straight ahead position there is virtually no assistance in order the give the driver as much direct control as possible, and even at low speeds the driver�s feel for the road surface is never impaired.

The rack and pinion steering system for the all new 9-3 continues this tradition. The hydraulic pump is camshaft-driven and the rack is mounted low down at the back of the front sub-frame. The geometry and tuning of the front and rear suspensions also combine to give the steering its distinctive feel, linearity and responsiveness. At just 2.97 turns from lock to lock, it is the quickest steering yet fitted to a Saab car.

As a general indication of the tautness of the all new 9-3�s chassis, tests show its lateral acceleration response time � the speed at which all chassis response to a steering input is completed � is about 30 per cent faster than average for this size of car.

Advanced Electronic Stability Program (ESP)

The fine chassis dynamics of the all new 9-3 is supplemented by an advanced, Saab-tuned ESP system � standard on all models � which is designed to gently counteract over-exuberance or misjudgements from the driver.

The ESP has been honed by Saab technicians using dedicated software to match the behaviour of the 9-3 chassis. The �intelligent� system is extremely progressive in use and is designed to function almost imperceptibly, avoiding harsh interventions when the chassis has already reached the limits of adhesion.

A yaw sensor in the centre of the car detects movement around the vertical axis and a sensor on the steering column measures the steering angle being applied. Inputs from these sources are then correlated with the speed of the car.

The system is extremely flexible and it is programmed to execute whatever actions will most effectively prevent the onset of a loss of control. Depending upon the chassis�s disposition, it is possible for braking to be applied via the ABS system to all four wheels at once, as well as control of the electronic throttle.

All New Saab 9-3 In Focus � Making the Right Noises

Stefan Svedhem�s brief in the development of the all new 9-3 was a simple one: turn noise into sound. His role was to ensure that the improvement in levels of noise, vibration and harshness (NVH) was at least equal to the progress made in the chassis�s ride and handling qualities. Whilst that meant eliminating unwanted noises, it also required sophisticated �noise management� or, as Stefan prefers to say, turning noise into sound.

"Noise is usually something irritating and unwanted," says Stefan, Manager of Saab�s Noise and Vibration Center, "whereas sound is something we appreciate and feel positive about." The work of Stefan and his team included everything from eliminating squeaks and rattles and checking �click� quality from the switchgear to making sure noises from the road and powertrain were the �right sounds�.

In addition to making hundreds of hours of sound recordings from different positions inside the cabin, the team also used a powerful, finite element computer model. With over 400,000 elements, this was the main tool in combating structure-born noise and vibration inside the car.

"We have made a lot of progress with low frequency noise, typically the bump/thump from the road transmitted through the suspension," says Stefan. "And we have balanced this with improved insulation for high frequency sound, such as tyre and wind noise."

Good NVH does not necessarily mean eliminating noises altogether because sounds, such as engine or road noises, can provide relevant signals for the driver. It would be disorientating to be placed in a complete noise vacuum.

"Our work with noise," adds Stefan, "usually involves what I call the �three I�s�. Information, where the driver should hear what he expects, such as when turning the starter or operating a switch. Impressiveness, where noises should become nice sounds, such as when the engine is being revved or when the door closes with a nice thud. Lastly, there is irritation, and these are noises we don�t want to hear at all, such a poor door seal and, of course, squeaks and rattles."

Design and Aerodynamics
Distinctive Sports Sedan Styling

"Saab�s design DNA runs right through this car. It looks clean, modern and sporty; combining some traditional Saab styling cues inside and out with the best timeless qualities of Scandinavian design."
Michael Mauer, Executive Director, Design.

All New Saab 9-3 Highlights:

 

Sporty, coupé-like exterior styling
Wider body, longer wheelbase gives more spacious cabin
Distinctive Saab design harmonising exterior and interior
Excellent high speed stability, low 0.28 Cd.
Lift forces reduced by 30 per cent

 

The styling of the all new Saab 9-3 clearly positions it as a Sport Sedan from Saab. The harmonious lines are soft and organic, yet well defined, communicating the car�s sporty character through an impression of power and strength.

The gently arching roofline flows between the steeply raked front and rear screens to create a coupé-like profile. The design team has stamped out the car�s distinctive Saab personality by combining sweeping lines and curves for both the exterior and interior.

Exterior Design

Compared to its predecessor, the new car is 55 mm wider and benefits from a 70 mm longer wheelbase. The shorter front and rear overhangs mean the overall length of the car is similar at 4635 mm. The more purposeful stance is also reinforced by a small 10 mm reduction in ride height.

The swept back, frontal styling clearly establishes the new 9-3�s sporty credentials. The �delta� effect of the Saab grille with its integrated headlamp units steeply angled back is a striking evolution, the rearmost corner of each housing being swept back 450 mm behind the centre point of the bumper. It is a similar angle to the delta wing in the Saab grille and also matches the traditional wraparound proportions of the windscreen.

The finely proportioned profile of the car also incorporates widely recognised Saab styling cues: the combined teardrop form of the side windows with a disguised B-pillar; the wedge shape and high waistline culminating in that distinctive �hockey stick� curve into the C-pillar; a single waist line running the entire length of the car and, of course, those prominent oval-shaped door handles.

The all new 9-3 becomes the first Saab to incorporate a �monoside� body pressing, the inset mounting of the doors allowing extremely fine shut-line tolerances, giving the car a strong and solid appearance, as well as further improving aerodynamic efficiency.

On most variants, the lower ride height is emphasised by the deep, colour-keyed side sills and front and rear bumper mouldings, making the whole body appear low-slung and close to the ground. The curvature of the wheel arches, with reduced clearances, and the location of the wheels (15,16, or 17-inch) to the outer edges of the bodywork with negative camber contributes to a more purposeful stance. In Aero guise, the all new 9-3�s sports styling is taken one step further with discreet side sill flares and bumper extensions.

At the rear, the triangular, side cut-out of the light clusters is another Saab design signature, as is the subtle, raised rear lip of the boot lid first seen on the Saab 9-5 sedan. The rear proportions of the car are particularly clean and well-balanced, the horizontal sweep of the rear light clusters providing a counterpoint to the vertical lines of the tail. Apart from the Saab emblem on the bonnet, the boot lid carries the car�s only visible badging: the 9-3 model designation on the nearside and the engine denomination on the offside, flanking the Saab badge.

"The car�s shape is intended to reflect its essential character, which is dynamic and sporty. It also avoids any �faddish� styling, which is not the Saab way and also dates very quickly", explains Aamer Mahmud, Chief Designer of the all new Saab 9-3.

"The coupé-like profile, the teardrop shape of the side windows, the shorter front and rear overhangs and the way the wheels fill out the wheel arches are all features intended to give this car a strong sense of forward movement."

Interior Design

The finely sculptured interior of the all new Saab 9-3 provides spacious and comfortable accommodation for four adults. It is larger in a number of key dimensions than its predecessor. The use of high quality materials and the standard of fit and finish is everything you would expect from a premium car.

Shoulder width has grown generously and is 81 mm wider in the front and 66 mm wider for rear passengers than the outgoing model. The longer wheelbase means that rear passengers also enjoy a useful 38 mm increase in legroom.

The overall design echoes the soft curves and flowing lines of the exterior. In the same way, the all new 9-3�s unfussy styling is clearly a natural evolution from previous Saab models. The fascia layout, the supportive seating, the shape of the door panels and the feel of the tactile, soft-touch controls are all very modern interpretations of classic Saab styling themes. It is a harmonious interior that could only come from Saab.

Attention to detail, so typical of Saab, abounds. The gentle contours in the B-pillar trim are a precise continuation of the lines in the door panels. The rear seat belts are neatly housed just above the rear seatbacks, avoiding unsightly slots in the C-pillars. The LED for the alarm is integrated into the fascia sun sensor. Even the seat height adjustment levers are coated in a soft-touch plastic finish.

The interior is presented in a choice of �light room� (parchment) or �dark room� (grey) tones.

Aerodynamics

The final shape of the all new Saab 9-3 is the product of a painstaking liaison between body stylists and aerodynamicists. Saab�s decision to move from a hatchback shape with a relatively narrow track to a wider sedan format posed a tough challenge to the ingenuity of Chief Aerodynamicist Hakan Danielson and his team. Their mission was to produce a shape that cleaves the air as efficiently as possible, giving good high speed stability, optimised fuel consumption and low wind noise inside the car. The result is an impressive drag coefficient of 0.28, equalling best in class performance.

"We have managed to reduce the Cd value by more than 10 per cent compared to the old model, even though the increased width of this car means we are punching a bigger hole in the air," says Danielson.

Slippery shape

The team concentrated its efforts on achieving smooth airflow over, around, through and under the car, paying particular attention to points of flow separation at the rear in order to reduce turbulence by reducing the size of the car�s wake. This improves stability. The shaping of the side sills and the radius and curvature of the rear corner of the C-pillar also helps reduce drag.

The rear edge of the bonnet lid kicks up to smooth the passage of air on to and around the windscreen and the team worked hard to reduce disturbance where the bottom of the rear window joins the boot deck, a particularly sensitive area in �notchback� shapes. The subtle upturn of the rear edge of the boot lid is, in effect, an integral lip spoiler which helps reduce the size of the car�s wake, the area of turbulent air that trails behind the car at speed.

Good airflow management also contributes to keeping the windows of the car as free from grime as possible. For example, the door mirror casings have a small spoiler-like profile in the bottom surface to reduce contamination of the side windows.

In addition to its excellent low drag shape, the team has also made major strides in improving stability. Compared to its predecessor, lift forces at the rear axle � an important determinant of high speed stability, especially under braking � are reduced by an impressive 30 per cent. A value of 0.11 Clr (coefficient of rear lift) is again on a par with best in class.

Low wind noise

Special attention has been given to reducing wind noise. The adoption of monoside body pressings, with inset doors and seals, makes a significant contribution. There has also been fine tuning of the A-pillars and door mirrors.

The traditionally deep curvature of the windscreen reduces the acceleration of the airflow as it approaches the A-pillars, which have a flattened radius where they connect to the windscreen to minimise airflow disturbance. The bottom edge of the door mirror casings is also extended rearwards by 5 mm to further reduce the likelihood of wind noise at speed.

Good airflow management even plays a safety role in the all new 9-3. The �wraparound� rear light clusters have an optimised radius that gives a distinct separation for airflow along the side of the car. However, careful shaping of the angle actually helps the air �turn the corner� first before it separates. The creation of a flow over part of the light clusters has the effect of helping to reduce the build up of road grime, which can impair the visibility of the lights.

Under the car

Airflow underneath the car is becoming an increasingly important area of aerodynamic fine-tuning and the forward lower link of the rear suspension has been specially shaped to reduce wind resistance and minimise the accumulation of road grime on the wheel rims. It is the first time Saab has aerodynamically shaped a suspension part.

Testing

Advanced CFD (Computational Fluid Dynamics) modelling now replaces a great deal of laborious work in the wind tunnel and also allows faster, more effective communication between project team members. For example, CFD played a vital role in the visualisation of airflow and speeded up optimisation work in the wind tunnel. CFD was also the main tool for optimising internal airflows: in the engine bay to control heat build-up from the engine and in the passenger compartment for best possible comfort.

Full-scale optimisation work was carried out in the wind tunnel at Stuttgart University, using a rolling road. But before that work began, advanced test methods developed by Saab made it possible to test up to 70 different body shapes in one-fifth scale during an eight hour shift in the tunnel. In this way, aerodynamicists and designers work very closely together and a large number of suggested changes can be investigated to meet aerodynamic targets.

Further wind tunnel testing was also carried out at the Motor Industry Research Association (MIRA) in the United Kingdom and in Detroit in the United States for wind noise suppression.

All New Saab 9-3 In Focus � Handling the Handshake

First impressions are always important. A firm handshake, for example, inspires confidence and that�s what the door handles of the new Saab 9-3 are designed to do. "It�s like meeting someone for the first time," explains Aamer Mahmud, Chief Designer of the all new Saab 9-3. "The door handle is the first contact a customer has with the car and it should make the right impression." For Saab that means having a very robust, strong and easy to use design.

Saab�s �signature� oval door handles can be gripped easily from the top or bottom, whichever is most comfortable. Women do not risk damaging their fingernails and gloves do not need to be removed. And in the unlikely event of a door being jammed shut in an emergency, a rope can be easily be looped around the handle.

All New Saab 9-3 In Focus � Unique Front Wheel Spoiler

"From my point of view, it would be great if the new car was about 30 cm narrower and two metres longer," jokes Hakan Danielson. "However, we are designing a road car, not a land speed record-breaker!"

Behind the jocularity Danielson makes the point that he can never achieve aerodynamic perfection in the real world. Instead, his team must concentrate their efforts where the return is greatest. As a result, they have developed a unique �two step� spoiler ahead of the new Saab 9-3�s front wheels. Although barely visible, the carefully shaped moulding makes a significant contribution to smoothing the passage of air under the car.

"We have put a lot of work into this area," says Danielson. "There is a great deal of turbulence around the front wheels and inside the wheel arches. This disrupts the smooth flow of air under the car and we have carefully shaped the spoiler to lead the air away from these areas, channelling it exactly where we want it.

"No-one has put as much effort into this feature as we have at Saab and we are convinced it has been worthwhile. The results in the wind tunnel prove how effective it is."

Electrical Architecture
High Speed Connections

"The advanced electronic systems in this car give us a powerful platform to accommodate all likely developments in the fast-moving fields of infotainment and e-services." Patrick Lundblad, Infotainment and e-services specialist, all new Saab 9-3

All New Saab 9-3 Highlights include:
 

Most extensive systems use of fiber optic technology
Hi-tech cable technology increases data speed, cuts weight by 50 per cent
Bluetooth wireless connection for Internet and office functions
Platform for advanced infotainment systems
Driver-friendly satellite navigation

 

All major mechanical and electrical functions in the all new 9-3, including numerous driver and passenger comfort features, are precisely and reliably controlled through an advanced digital signal network.

It incorporates the auto industry�s most extensive systems application of fiber optic technology. This provides a signal capacity 50 times greater than the fastest conventional wire links and offers a secure platform for the application of advances in telematics, enabling owners of the all new 9-3 to conveniently install new functions.

The entire electronic and electrical network uses databus transmission � often referred to as �multiplexing� � to connect groups of electrical subsystems and pass on signals from all the car�s sensors.

In this way, a CANBUS (Controller Area Network) uses just one or two wires with microprocessors, transistors and LEDs (Light Emitting Diodes) to replace a complicated wiring harness and all its associated relays, switches and bulbs.

CANBUS technology offers great benefits in weight saving, reliability and data transmission capacity. It is used to connect the all new 9-3�s main subsystems: powertrain, chassis, body, infotainment, telematics, navigation and climate and comfort.

Smart Networking
A battery of sensors are the nerve endings of the all new 9-3 and the data they provide is dispatched as packages of digital signals, or �Buses�, along three information highways, stopping where required at 44 sub-stations, or microprocessors, for analysis and subsequent action.

A powerful control module governs each of these highways and their substations; all three integrated with each other to ensure there are no traffic jams or conflicting requirements.

If all the functionality of the all new 9-3 was to be achieved using a traditional, complex wiring harness, it would weigh twice as much, at more than 40 kilos, and be twice as long, at 1,600 meters.

A single wire highway, or low speed Bus, with a capacity of 33 kbits per second, connects functions within the car: the ignition switch, steering column lock, airbags, the main instrument panel, interior lighting, doors, mirrors, windows, security alarm, gear shift position and, where fitted, the sunroof, electrically-operated seats and parking assistance.

Powertrain control, the Trionic 8 engine management system, ABS, TCS, ESP and related functions are all connected by a dual wire, high speed Bus, with a transmission capacity 15 times greater at 500 kbits per second.

Fiber Optic Innovation

The third highway is the largest yet fitted to a passenger car, using fiber optics instead of wire to give a massive capacity of 25 Mbits per second, 50 times greater than that of a dual wire bus. It is utilised by all three infotainment systems, the integrated GSM telephone and the GPS navigation system.

The fast moving world of information technology is likely to place increasing demands on the �in-car� time of drivers and passengers and the all new Saab 9-3 is configured to accommodate all likely future developments in digital communication to and from the car.

Well Connected

Saab is one of the first auto manufacturers to introduce Bluetooth?* wireless technology, which uses a short range, low frequency radio link to replace cable connections for mobile devices, PDAs (Personal Digital Assistants) and peripherals.

The all new 9-3�s integrated GSM telephone is equipped with a Bluetooth-certified radio transmitter/receiver operating on the globally available 2.4 GHz bandwidth. An effective range of up to 10 meters allows the convenience and flexibility of cableless connections in and around the car with, for example, a laptop, palm pilot or a work organiser. This feature will be available during 2003 for Australia and New Zealand.

In this way, the telephone provides a quick, modem link for external communication and Internet access and also allows the use of a wireless Bluetooth headset.

Telematics

The General Motors �OnStar� telematics service can be specified by 9-3 owners in the United States and will be available for the European market when the infrastructure is in place. It may also be considered eventually for Australia and New Zealand.

Satellite Navigation

Saab has taken particular care in making it as easy and as safe as possible for drivers of the all new Saab 9-3 to follow route guidance instructions. Direction arrows are shown on a small screen, the Saab Information Display (SID), which is positioned high up on top of the fascia so it can be viewed with minimal eye line adjustment. This is in addition to voice prompts and a 5.8-inch (15 cm) monitor screen in the main instrument panel.

The same care has been taken by Saab in specifying the software for its DVD-supported GPS system, including customised graphics, map data and voice instruction, as there was no �off-the-shelf� system that met Saab�s stringent requirements.

All New Saab 9-3 In Focus � The electronic key

The electronic key to the all new 9-3 is, of course, simply a means of operating a transponder. But what shape should it be? A car ignition key may now look like a credit card or a rubber ball, either using a unique PIN code to initiate a signal or sending a signal through a transponder.

Saab found the answer in a long-held Scandinavian design principle which states that �form should always follow function�!

Using a credit card also means pressing a start button. It may be fun but it is not good ergonomics. Two separate movements are not necessary when one, with a traditional, engage twist, is all that�s needed.

The design department was involved from the start in deciding the shape of the Electronic key," says Saab product marketing specialist Fritz Magnusson. "We have something different which is quite hi-tech but still very ergonomic and easy to use. It is an item the owner can identify with and represents the sophisticated character of the new car. If the car ever has a flat battery, you can simply pull out the metal blade and still get into your car."

Interior
More Space and More Grace

"The interior is designed to be light in appearance and generally less heavy looking. A consistent design theme for the shape and layout of all the controls and displays keeps them well integrated so they are pleasing to the eye."
Aamer Mahmud, Chief Designer, all new Saab 9-3

All New Saab 9-3 Highlights:
 

Focused driver�s environment
�Profiler� customisation function
High position display
Three �forms� � Linear, Arc, Vector
High-performance model � Aero
Intelligent dual-zone automatic climate control
Advanced infotainment and audio systems

 

Focused Driver�s Environment

The all new Saab 9-3 is designed to provide a near perfect driving position for the vast majority of drivers, almost irrespective of size, through a multi-adjustable driver�s seat and a steering wheel that is adjustable for rake and height.

The main instrument panel gently arcs round the driver, an evolution of the same theme in the previous model. In typical Saab fashion the controls are all logically grouped, those most frequently used being nearest to hand and closest to the driver�s natural field of vision. The short gear shift lever is just a hand span away.

The main dials - a large speedometer, with a compressed scale above 140 kmh, flanked by a smaller tachometer and a combined fuel/water temperature/turbo boost gauge - are recessed in traditional Saab fashion. They are white on black and continue to be softly illuminated in green as Saab believes this is the most restful choice for night driving.

Also located in the main instrument panel are twin adjustable air vents and infotainment system controls, with a 5.8 inch (15 cm) high resolution monitor screen displaying particularly clear graphics on models fitted with satellite navigation.

The �Profiler� feature, fitted as standard on all models, offers great scope to pre-set a wide range of functions according to personal preference. It is particularly user-friendly with selections highlighted through a single, rotating button linked to on-screen prompts. The operation of the automatic climate control; the clock/alarm; speed scale illumination, seat heaters, rain sensitive wipers, parking assistance and anti-theft can all be tailored through �Profiler.�

Saab�s unique �night panel� feature, which allows the driver to switch off all main instrument illumination at night (except for the speedometer) is, of course, standard fitment. This removes visual clutter and potential distraction, providing a more restful driving environment.

New for Saab is a high position display, located in a binnacle at the top of the fascia, near the base of the windscreen. For safety reasons, this is as close as possible to the driver�s natural field of vision so that information can be seen without any head movement or much eye re-focusing. The Saab information display (SID) shows, for example, local time, outside temperature, radio settings, warning signals and direction arrows from the satellite navigation system (where fitted) to minimise distraction by driving and having to check route directions on the main screen. It also shows information about the Profiler function and the car computer.

As befits a sporting sedan, the three-spoke steering wheel is slimmer and sportier than previous Saab designs. It carries buttons for the infotainment system, telephone and also the Sentronic gear shifting. A substantial central console below the main instrument panel is inclined slightly towards the driver and sweeps elegantly down between the front seats. It accommodates the automatic climate controls, more minor switchgear, the gear shift lever, ignition switch, handbrake and a large central storage area with smaller, roll-top compartment and cup holder below the centre arm-rest.

A particularly neat innovation is the disguised handbrake which is beautifully integrated in the edging trim of the console. It is a Z-shaped lever, self-adjusting and with a positive, easy-to-use action. On the other side of the console, mirroring the integrated handbrake is a �Smart Slot� detachable sleeve, for further storage of small items.

The ignition switch continues to be located alongside the handbrake in true Saab tradition. It is now entirely electronic in operation and the customary, mechanical Saab reverse manual gear lock is now replaced by an automatic, electronic steering column lock.

Seating comfort

Saab has earned an enviable reputation for class-leading seating comfort and the all new Saab 9-3 continues that tradition. All four seating positions are upholstered to be comfortable and supportive, without being too firm. The front seat squabs and backrests are well bolstered where it matters to give excellent under thigh and lateral back support.

The seats and door panels in the Linear model are clad in a new, high quality woven textile. The Vector model uses a blend of leather and textile for a true sporting feel, while the luxurious Arc model is full leather, as is the range-topping Aero with its superb sports seats. The rear of each front seatback includes a large storage pocket, carefully shaped to optimise rear seat leg room.

All four seating positions offer similar standards of comfort. All rear seat passengers in the new 9-3 benefit from their own adjustable heating / air vents, reading lights, cup holders, a centre armrest and generous storage facilities.

Saab�s new generation active head restraints (see Safety section for details) are fitted to both front seats and the rear head restraints can be folded flat without compromising seat comfort.

Interior décor

Each of the 9-3 �forms� � Linear, Vector, Arc � plus of course the performance Aero model, are designed to create a distinct ambience or atmosphere inside the car. The seats, door panels, other main interior trim and carpets are offered either in a �light room� (parchment) or �dark room� (grey) color scheme, depending on the model. However, the door cappings are always anthracite to integrate with the fascia and main instrument panel, and the interior headlining is always white.

The all new 9-3 line-up starts with the Linear form, intended to communicate an understated and modern Scandinavian environment. The seats and door panels are covered in a woven textile with contrasting textures, while the door trim inserts and the centre console are finished in anthracite.

Arc adopts real wood veneer and leather for a more luxurious ambience. The seats and door panels are beautifully upholstered in rucched leather and the door trim inserts and center console are finished in a satin look, poplar wood.

Vector is more progressive and performance-focused. The main instrument panel is sportier looking with the main dials finished with a chrome surround. The seats are also sportier in shape, with leather and textile inserts and more bolstering in the front seat squabs and backrests. The door trim inserts and center console are finished in matt chrome.

Aero is, of course, the ultimate performance expression of the all new 9-3. Here the interior and sports seats are finished in premium leather with Aero identification in all four seating positions, plus matt chrome finish for the door trim inserts and centre console.

Heating and Ventilation

All variants of the all new 9-3 are fitted with Saab�s automatic climate control (ACC) air conditioning system. Impressively, the variable displacement compressor is programmed to cool only the volume of refrigerant that is required to maintain a temperature setting, thus eliminating wasteful running.

Air is drawn into the interior through an extremely dense, chemically-charged filter which extracts dust, pollen and particles as small in size as three microns. The filter also prevents odors entering the cabin. Rear passengers benefit from adjustable, twin air vents at the rear of the central console, as well as outlets under the front seats.

The automatic climate control is fully programmable and dual zone, allowing different temperatures to be selected for the left or right hand side of the car, as first seen in the Saab 9-5.

The system is now taken a step further in the all new 9-3 by incorporating an automatic airflow balance control, which compensates for changing conditions outside the car, such as the effects of direct sunlight or shade. A sensor at the base of the windscreen detects the position of the sun and the intensity of sunlight reaching the car. A balance control program is then activated, directing airflow inside as required so that passenger comfort levels are kept constant.

The heated front seats now also benefit from an automatic temperature control, which will progressively lower seat temperatures as the interior warms up. Like the ACC system, this function can be pre-programmed through the Profiler customisation menu.

Infotainment

The all new Saab 9-3 benefits from one of the most powerful electronics systems installed in a series production car (see Electronics section for full details). Fiber optics are used to provide a high speed platform for the car�s extensive infotainment functions, the first time this technology has been used in the automotive industry for a complete network. It is already capable of handling all likely future requirements in the fast-developing field of infotainment and driver communication, making it easy for owners to fit upgrades at a later stage.

The cabin of the all new 9-3 sets new standards for Saab in terms of interior refinement and noise suppression. The interior is designed to provide excellent acoustics, irrespective of seating position, and the new 9-3 offers a choice of three modular audio systems which can be changed or upgraded.

Linear comes standard with the Saab Audio system including in-dash single CD player, am/fm tuner, steering wheel controls, and �Premium 150� sound with 150 watt output through two amplifiers and seven speakers. The single antenna is integrated in the rear window.

Arc and Vector are fitted as standard with the Saab Infotainment system, which in addition to Linear features monochrome visual display and telephone keypad.

Aero, the ultimate model in the range, gains in addition: �Premium 300� sound through three amplifiers and 13 speakers; as well as integrated telephone and in-dash CD player with six disc capacity.

Saab Infotainment Plus, available as an option later, is a communication centre and further includes integrated telephone, a colour display, GPS/DVD navigation and Internet browser.

There is also an auxiliary input socket in the center console, allowing an MP3 player, for example, to be connected to the audio system.

Storage and Load-carrying

Although the all new Saab 9-3 is a sport sedan, in the practical tradition of all Saab cars it offers excellent on-board storage and load-carrying facilities.

There are no less than 13 places in the passenger compartment where various items can be stowed. Up front, there are two good-sized door bins, a large air-conditioned glove compartment (cooled to 8°C), and two pouches at the front of the seat squabs.

The multi-functional centre console incorporates coin slots and a 12-volt outlet for a battery charger within the main storage compartment under the armrest, as well as input socket for an MP3 player and the roll-top compartment with cup holder. The Smart Slot provides convenient storage for items such as credit cards, pencils and a small wallet or notebook.

Rear seat passengers are also well served. In addition to the two door bins, there are large pockets in the front seatbacks and a flat storage area in the center armrest. A neat double cup-holder is also spring-mounted in the front of the seat squab.

The boot is deep and tall with a wide opening and an ample 425-litre capacity. Two pull handles in the top of the boot lower the 60/40 split rear seat-back, which includes a ski-hatch, to give a flexible and impressive load-carrying potential. The floor of the boot also has four tie-down loops to safely secure heavy items.

All New Saab 9-3 in Focus � World�s Cleverist Cup-holder!

Most of the work of Saab engineers is, of course, a serious matter but once in a while an opportunity comes along where they can indulge in a sense of play. Designing the ultimate cup-holder was just such an occasion.

The cup-holder in the front of the Saab 9-5, which automatically swivels through 90 degrees from a vertical position, has earned wide acclaim for the beauty and intelligence of its design.

So when it came to designing a dashboard cup-holder for the new car, the Saab team were determined to do something special as their encore. The result is �The Butterfly�. Here there are two separate movements in different directions, one for the base and one for the retaining hoop (the �wings� of the butterfly), both hinged from one arm. The highly geared action of the wings opening and closing as the arm moves in and out is quite impressive.

"It is, perhaps, a little over the top", concedes interior safety engineer Richard Lindstrand, who co-ordinated The Butterfly�s development. "A number of us in the project team wanted to do something a bit special and most of the design work was, in fact, done in our own time. It really was a group effort and we like to think The Butterfly will bring a smile to the face of a few people."

Ownership and Accessories
Owning and Enjoying the all new Saab 9-3

"This car will be as rewarding to own, operate and live with as it will be to drive."
Thomas Lindskog, Executive Director - Aftersales.

All New Saab 9-3 Highlights:

 

Extended anti-corrosion warranty
30 per cent reduction in scheduled servicing costs
Low speed accident damage protection
Favourable insurance ratings
Large design and lifestyle-orientated accessory range

 

The improved build and materials quality throughout the all new 9-3 is reflected in a longer anti-corrosion warranty and a substantially reduced cost of ownership, including lower servicing and insurance costs.

Good serviceability and improving the cost and convenience of ownership was the main focus of the Aftersales group which liased with the project team throughout the all new 9-3�s development.

An exclusive range of accessories is available from launch, giving owners scope to enjoy the full potential of their new Saab.

Extended anti-corrosion warranty

The anti-corrosion warranty, covering body perforation, is extended from six to 10 years, a result of Saab�s confidence in under-body joint and sealant treatments and new electro-galvanizing procedures.

The body-in-white is prepared, sealed, galvanized, primed and painted at one of the most modern paint shops in Europe where quality standards are considered to be class-leading. All primer and paints are water-based, except for the final clear lacquer finish.

Reduced Servicing Costs

Longer service intervals and reduced workshop times for the all new 9-3 are designed to give scheduled maintenance savings of up to 30 per cent compared to its predecessor.

The excellent quality of major mechanical components, due to better machining and finer tolerances, has allowed Saab to move away from rigid time and distance restrictions for scheduled servicing. It is now more important to monitor how the vehicle is actually used by its owner.

The engine management system logs key usage parameters, such as the number of cold starts, journey distance and engine speeds used, and applies an algorithm to inform the driver when an oil change is due. The maximum service interval is now every two years, or 20,000 kms for owners in Australia and New Zealand. At any time, the driver can also request notification of when the next change is due.

With engine coolant filled and sealed for life, the only other major service items for the all new 9-3 are brake/clutch fluid, spark plugs, the interior air filter and tyres.

Quicker repairs, lower insurance

Saab engineers have worked closely with representatives of leading insurance companies � including the NRMA in Australia � to introduce ways of minimising accident repair bills, as well as improving vehicle security and anti-theft protection. It is hoped that this close liaison will result in highly competitive insurance groupings and lower premiums.

A number of design elements in the outer body will make accident and other repairs easier and faster. For example, electrical wiring and connection points are routed and located away from areas more vulnerable to crash impacts, making repairs easier as well as improving safety. For example, there is just one single connection point between the engine and main wiring harness and this is in a well-protected position behind the battery.

Low speed frontal collision protection, through �self-repairing�, energy absorbing bumpers (for impacts up to 8 km/h) and deformable �crash boxes� (for impacts up to 15 km/h), now bolted in position for quick replacement, helps protect the body structure from serious damage that would require expensive reinstatement. The front wings are also bolted to the main structure to make removal and replacement easier and less time-consuming.

Accessories tailor-made for individuality

Saab is launching the all new 9-3 with the large range of accessories. These include sporty design and more practical and lifestyle-orientated items.

Design

For a more distinctive look, inside or out, there are a number of sporty design enhancements. Exterior items include: front spoiler, rear spoiler, sill extensions, fog lights, sports exhaust and a range of alloy wheels up to 18 inches. For the interior there are poplar wood or alloy trim inserts for the doors and the gear shift lever and housing, manual or automatic. Also a leather/wood steering wheel.

Lifestyle

These features are designed to support owners of the all new 9-3 in the enjoyment of their leisure pursuits. They include: cycle, ski, snowboard, surfboard, canoe and kayak holders; roof rack, roof cage and roof boxes and removable or fixed tow bars. Cargo mat, luggage box, cargo net and fold-out rear bumper scratch protectors are also available.

Comfort and Security

Pre-wiring facilitates the addition of entertainment and navigation equipment. Also available are a hands-free phone kit, CD changer and a pedal extension kit.

Saab Parking Assistance and the Saab Anti-theft Alarm is standard on Aero but available as options on Linear, Arc and Vector. A first aid kit, spare bulb kit and towing line are also available.

All New Saab 9-3 In Focus � Creating Space

Extra storage room inside a car is always welcome and in the all new 9-3 Saab designers have created space in an unlikely place, the Smart Slot, that �hidden� handbrake between the front seats which can be used for holding credit cards, pens, a small wallet or notebook.

It can also be put to good use as home to a choice of accessories, including a 6-disc CD holder, an expanding cup-holder or even an ice-scraper.

Very discreet, very neat and very Saab!

Positioning
Saab enters Premium Compact Sport Sedan sector

"The all new Saab 9-3 is for modern, youthful professionals who are independent thinkers. They want a great driving experience and a car that sets them apart from the mainstream."
Knut Simonsson, Brand Director - Saab Automobile

All New Saab 9-3 Highlights:

 

First Saab in premium, compact sport sedan segment
Focused on involving, �fun to drive� experience
Sedan format broadens appeal
Saab customers more highly educated
300 new retail sites under Saab Unlimited initiative

 

The all new Saab 9-3 pitches Saab head-to-head against the established players within the premium Sport Sedan sector, offering a new, more self-expressive, alternative choice.

The all new 9-3 will see Saab compete for the first time in the growing premium, compact sport sedan segment where it will be targeted at youthful, professional and business-orientated customers who want to enjoy a product offering sporty, dynamic performance without following the crowd.

In replacing the three and five-door bodystyles of the previous model, the all new 9-3 Sport Sedan spearheads the biggest model roll-out program in Saab�s history. The launch of a four-door sedan format is the first stage in the creation of a bold, new family of cars, each model adopting a unique bodystyle and focused on the particular requirements of a different niche in the market.

Putting Sporty Appeal First

A key requirement in the design brief for Saab�s first sport sedan was the development of a clear �fun to drive� appeal, delivering a rewarding experience with a high level of driver involvement.

In being designed and built from �the driver outwards�, the all new 9-3 gives Saab�s traditional philosophy a new focus. The outstanding qualities of the chassis, the refined performance of the all-turbo powertrain and the driver-orientated cabin are integrated as never before. The more sophisticated and involving driving experience sets a new benchmark for the brand.

It is a formula aimed at winning new conquest customers from other premium brands, as well as appealing to existing customers and those aspiring to move up from the volume sector of the market.

The development program for the all new 9-3 has included the most intensive benchmarking process ever undertaken by Saab. The performance of key competitor products was compared across a wide range of parameters including: handling, ride, steering, braking, powertrain performance and refinement, interior functionality and ergonomics, build and materials quality, comfort and, of course, safety. The performance of the all new Saab 9-3 in all these areas is designed to exceed, or at least equal, the best in the sector. Overall, it promises to set a new standard for the class.

Customer Profile

Potential customers are predominantly male, between 35 and 45 years of age, professionally-qualified and engaged in business and commerce. The all new 9-3 is designed to appeal to a growing proportion who want a sport sedan that is more distinctive, yet less ostentatious, than the more commonplace mainstream premium products that dominate the segment.

Research in Europe among Saab 9-3, BMW 3-series, Audi A4 and Mercedes C-class owners shows up some key differences between Saab customers and the rest. Saab owners are more highly-educated, 58 per cent having been to university or college, compared to an average 33 per cent among competitors. They are also younger, with an average age of 45 years (compared to 52 years); they cover a higher annual mileage, an average 27,000 kms (compared to 21,600 kms) and enjoy a higher household income, Euros 111,350 (compared to Euros 79,760).

In Australia the trend is similar with 72 per cent of Saab owners having university or post-graduate qualifications, compared to 57 per cent for owners of BMW 3-series, Mercedes C-class and Volvo S60. Saab owners in Australia are also younger with an average age of 47 years (compared to 51 years), they also drive greater distances, an average 20,000 kms (compared to 18,500) and also enjoy slightly higher household incomes, $193,000 (compared to $188,000).

Targeted Range

In adopting a sedan format, Saab is confident that the appeal of the new 9-3 will be significantly broadened. Research shows that there are many more potential customers for a premium sedan than there are for a premium hatchback. The range is structured to appeal to each of its target customer groups.

The ranging-topping 155 kW Aero and 129 kW Vector and Arc variants are expected to provide a highly-competitive alternative to current products from the established segment leaders.

For those moving up into the premium sector from a wide number of volume manufacturers, the 110 kW Linear still offers a very high standard of performance and equipment for the price.

For current 9-3 owners the new range is an opportunity to enjoy Saab�s latest technology, promising a significant step forward with a more sophisticated and much stronger �fun to drive� product.

As these customers would expect from Saab, the new sedan format offers a fully-folding, 60/40 split rear seat and generous boot capacity. Future models in the all new 9-3 range will meet the requirements of customers whose overriding priority is maximum versatility.

Saab Unlimited

Saab�s entry into the premium, compact sporting sedan segment is being complemented by the development of a new marketing and retail strategy, Saab Unlimited.

At the start of new 9-3 sales, 300 dealerships in major markets around the world will have been upgraded and appointed in prime locations as Unlimited Partners. The branded style of these facilities and the services provided will meet the highest standards of customer care.

Up to 10 Unlimited Partners will be ready in Australia and New Zealand in time for the start of sales of the all new 9-3 around late October.

At a small number of prestigious, cosmopolitan locations there will also be City Centers, aimed at taking the Saab brand out to where potential customers work, travel, shop or simply socialise. These sites are designed to give Saab optimum exposure as shop windows for the brand.

Australia has been earmarked a priority market for a City Centre, with one expected to open on the East Coast during 2003.

The Saab Unlimited initiative also involves the introduction of sophisticated customer relationship marketing (CRM) procedures and the provision of attractive finance offers for specific customer groups.

Saab Automobile Australia is already well advanced with its CRM implementation and, in fact, is setting the global pace for Saab in some key areas of CRM.

Powertrain
Integrated Turbo Power

"The closer integration of the new engines and transmissions has given us a far more sophisticated and refined level of performance."
Kent Bovellan, Project Leader, all new Saab 9-3

All New Saab 9-3 Highlights include:

 

All new, all-aluminium, 2.0-litre turbocharged engine offers three power outputs
Excellent torque, driveability and refinement
New Trionic 8 engine management system tailored for turbocharging
New automatic and manual transmissions, plus Sentronic

 

Exceptional turbocharged performance delivering new levels of mechanical refinement and driveability were the objectives of powertrain development for the all new Saab 9-3.

Saab engineers have long been regarded as world leaders in the art of turbocharging, a distinction recognised by Saab�s appointment as the Center of Expertise within General Motors for turbocharged petrol engine development. Now with the launch of the all new 9-3, Saab has matched the redoubtable torque of its engines with a more progressive power delivery.

A new, all-aluminium, 2.0-litre turbocharged engine, based on the L850 series, has been developed by engineers based at Saab�s engine plant in Södertälje, Sweden; and is configured for three levels of power output: 110, 129 and 155 kW. Transmissions include an improved five-speed and a new six-speed manual gearbox, and a new five-speed automatic transmission with Saab Sentronic semi-auto gear selection as standard. During 2003 steering wheel controls will be offered for Sentronic.

Advances in electronic engine and transmission control deliver appreciable improvements in throttle response, torque delivery and power-on/power-off behaviour. The smooth, turbocharged performance of the all new Saab 9-3 is the perfect complement to its superb chassis dynamics for a rewarding, fun-to-drive experience.

New Lightweight 2.0-litre Turbo Engine

The all-aluminium, four-cylinder, 2.0-litre petrol engine is 15 kilos lighter than its predecessor. It is smoother, quieter, more compact and better packaged. It also operates with lower frictional losses for improved fuel consumption and lower exhaust emissions.

The block is perfectly �square� in configuration, with a bore and stroke of 86 mm, and carries a unique Saab four-valve cylinder head, maintenance-free chain-driven camshafts, counter-rotating balancer shafts, a dual mass flywheel and an integrated oil cooler. It is controlled by the latest Trionic 8 version of Saab�s own, in-house engine management system, the most powerful in commercial production.

All main internal components are unique to the turbocharged application in the all new Saab 9-3. These include a five-bearing forged steel crankshaft, strengthened con-rods, redesigned pistons and gudgeon pins, piston oil cooling jets and reprofiled camshafts. The cylinder head is a unique alloy casting optimised for turbocharging, with substantially revised inlet porting, modified inlet valves and sodium-cooled exhaust valves.

A major innovation for Saab is the in-board location of the turbocharger, behind the transversely-installed engine. This position allows an even quicker warm-up for the front exhaust catalyst; giving improved fuel consumption and lower cold start emissions, as well as benefiting weight distribution.

A GT20 turbocharger is used for the 110 and 129 kW engines with maximum boost pressures set at 0.5 and 0.7 bar respectively. A larger TDO4 unit, operating at 0.85 bar, is fitted to the 155 kW version, which also has more aggressive camshafts. Both turbos have integrated by-pass valves.

The power characteristics of all three engine variants set new Saab standards for running refinement, throttle response and progressive torque delivery, as well as yielding even better fuel consumption and lower CO2 emissions.

In common with all Saab petrol engines, outstanding levels of torque are generated at low engine speeds, with 90 per cent of the peak value available from below 2,000 rpm. Maximum power and torque figures are as follows:

 

1.8t 110 kW @ 5,500rpm 240 Nm @ 2,000rpm
2.0t 129 kW @ 5,500rpm 265 Nm @ 2,500rpm
2.0T 155 kW @ 5,300rpm 300 Nm @ 2,500rpm

 

Improved Driveability from New Trionic 8

Saab is alone among the world�s premium car makers in producing its own engine management system. The Trionic system is specifically geared to the needs of turbocharged engines and allows Saab to carry out speedier, more effective development work. Ignition timing, fuel injection, turbo boost pressure, air mass measurement and the throttle setting are all key engine functions controlled by the Saab-written Trionic software, making it the most sophisticated engine management system in commercial production for turbocharged engines.

In the all new Saab 9-3, Trionic 8 now incorporates engine start-up and temperature control and further developments for improving torque management and throttle response. It is this in-house capability that provides the key to achieving one of the powertrain development team�s main objectives: better driveability.

The torque delivery of the engine is now more linear. Under acceleration, Trionic can sense, for example, if there is insufficient grip available for a given throttle setting and will modulate engine torque accordingly. The adjustments are hardly noticeable but make the driving experience smoother and more enjoyable.

Uncomfortable jerks, which can be experienced when suddenly lifting off or stamping hard on the throttle, are also largely eliminated. Trionic is able to �read� and anticipate every driving situation, cushioning the transitory effects of large throttle movements by comparing parameters such as road speed, engine speed, engine loading and gear selected. The end result is a smooth, powerful and extremely pliable powertrain, devoid of �shunting� under sudden throttle movements.

The Trionic system enables Saab to constantly achieve improved operating efficiencies and is a powerful electronic platform for Saab�s own future engine technologies.

As a measure of its sophistication, Trionic is unique in monitoring ionisation rates at each spark plug to individually control and adjust the combustion process for each cylinder. This involves about two million calculations per second! To avoid such complexity, other systems used by competitors apply an average taken from all cylinders.

Unique Engine Installation

As part of the extensive program to minimise low frequency noise and vibration, Saab engineers have adopted a completely new �pendulum� technique for engine mounting.

In order to absorb the main torque forces, which are generated at the bottom of the engine, the entire powertrain assembly is, in effect, suspended from two top mounts, one hydraulically damped, in the engine bay. Two short, aluminium torque rods, with rubber bushings at both ends, are also fitted low down, between the back of the powertrain and the rear of the front sub-frame. One is attached to the oil sump and the other to the transmission. These act like mini shock absorbers, allowing lateral movement, in or out, of up to 20 mm, equivalent to a swing of 4.5° from the vertical, just like a pendulum.

This sophisticated installation directs forces to the bottom of the car�s structure and away from the passenger cabin, playing an important role in isolating the interior from unwanted engine noise and vibration.

New Automatic Transmission

A new �smart� five-speed automatic transmission is available for all petrol variants that includes Saab Sentronic, a sequential semi-auto gear shift. Steering wheel mounted Sentronic gear change controls will be available during 2003. The greater control offered by Saab Sentronic means that �sport� or �winter� mode settings are no longer required.

This transmission, produced by Asin AW, is adaptive to both the driver and road conditions and is programmed to fully exploit the Saab turbo�s power characteristics. It can sense changes in engine performance, engine load, road gradient or altitude and will quickly find the correct gear without any irritating �hunting�. It will also automatically engage neutral when braking to a stop.

For closer driver involvement, the shift lever can be moved across the gate to �manual� Sentronic mode, giving sequential �up� or �down� changes at will with full lock-up in all five speeds. This process will be taken a step further in 2003 with the option of steering wheel buttons, which bring gear-shifting control right to the fingertips of the driver.

Six speed manual gearbox

Saab�s transmission plant at Gothenburg is a major supplier of manual gearboxes to General Motors and for the all new 9-3 a completely new, six-speed manual gearbox has been designed.

It is capable of handling extremely high torque levels, up to 400 Nm, and features improved syncromesh for better gear shifting quality and double output shafts for lightness and compact size. It is standard fitment for the 9-3 Aero.

Improved Manual Gear Change

The gear change quality of the current five-speed gearbox is substantially upgraded for the all new Saab 9-3 by the adoption of a cable linkage, instead of rods, from the gear lever.

The driver now enjoys a faster gear change with a much smoother and more positive feel. In combination with the dual mass flywheel, noise resonance and vibration are also reduced. It is another small part of the powertrain program�s mission for improved on-the-road refinement.

All New Saab 9-3 In Focus � How Saab �turned the corner�

Saab engineers love to �talk torque� because it is an engine�s pulling power that defines its true performance. The ability to deliver strong, low down power has always been an outstanding feature of Saab turbocharged engines.

It is graphically summed up by that classic �Ayers Rock� torque curve, depicting the impressive power delivery of Trionic-controlled Saab turbos. Now for Ayers Rock, read Houston Astrodome!

Saab experts have succeeded in �turning the corner�, getting rid of that sudden, sheer cliff face. The smoother contour of �the dome� translates to an engine that�s more progressive, delivering more torque earlier and slightly less later, during pick-up from idle (at just 670 rpm) to 2,000 rpm. Once in the mid-range, towards the crown of �the dome�, it is, of course, business as usual.

Trionic 8 brings the turbo in slightly earlier and a clever, electronic sleight of hand is used at low engine revs, very briefly opening the throttle slightly more than requested in order to spool up the turbo quicker. It�s all possible thanks to the drive-by-wire electronic throttle and the power of the Trionic brain.

"The driver communicates with the engine through the accelerator pedal," says Birger Schlaich, Manager - Powertrain Integration. "And we want to make that experience as precise and pleasant as possible.

"Another good feature for better driveability is the programming of the signal from the accelerator pedal itself. At low speeds there is much more movement for a given amount of power in order to make the car nicer to control, such as when parking and reversing. At higher speeds, less movement is required and that�s better for a quick response when overtaking, for example.

"For the all new 9-3 we have done a lot of fine-tuning such as this to make the behavior of the powertrain as seamless as possible. We are quite pleased with the results."

Safety
Safety Optimised for the Real World??

"This is a car loaded with safety. We have incorporated the most effective features in the marketplace today."
Per Lenhoff, Head of Crash Safety Development

All New Saab 9-3 Highlights:
 

Uprated safety cage and deformable structures
More �Real life� crash configurations
75 crash tests, of which only 15 required by law
Second Generation Saab Active Head Restraints (SAHR)
Roof Rail airbags for side and severe frontal impacts
Sophisticated sensing for airbag/seatbelt deployment
Excellent driving safety with EBD, CBC and ESP all standard

 

Saab has a long tradition of successful work with car safety. In surveys of real-life collisions made by the US Highway Loss Data Institute (HLDI) or the Swedish insurance company, Folksam, Saab cars have always performed well, several times being ranked highest in their segment.

But the pursuit of improved safety is a never ending quest. The design of an all new car, such as the all new Saab 9-3, gives engineers a great opportunity to apply the lessons of real-life, raising their safety benchmark ever higher. As a result, the all new Saab 9-3 is expected to be one of the safest cars in the world.

For Saab, car safety involves two key areas: crash safety (passive safety) and driving (or active) safety. The all new 9-3 features important advances in both areas.

Crash impact resistance benefits from a number of structural systems first seen on the larger 9-5 model and the introduction of new occupant protection measures, including second generation Saab Active Head Restraints (SAHR) and Roof Rail Airbags. Front and side impact sensing is also more precise and the deployment of counter measures, such as the dual stage front airbags and seatbelts, is more occupant-friendly.

Greatly improved chassis dynamics keep the driver even more in control and therefore less likely to be involved in or better able to avoid a crash. Driving safety is advanced still further by the incorporation of EBD (Electronic Brake force Distribution), CBC (Cornering Brake Control) and ESP (Electronic Stability Program) as standard on all models.

More �Real-Life� Crash Configurations

Saab crash tests are designed to replicate what happens in real life on real roads, based on the findings of a database covering more than 6,000 real-life collisions involving Saab cars.

The structural design of the all new 9-3 and its behaviour in crashes is therefore designed for real life safety. It has been evaluated in 75 different crash configurations, which take occupants of all sizes into consideration and is a record number for Saab in a new model development program. Only about 15 of these configurations are legally required.

Prototype tests are carried out in the laboratory and outdoors through a wide range of speeds and configurations including: frontal car-to-car, moose impact, frontal under-side, side swipe, truck-to-car, side impacts and rollovers.

Advanced crash simulations, using finite element methods (FEM), help find the right solutions before any prototypes are built. Support by simulation is used throughout the development process for structural design, as well as for tuning the occupant protection systems, such as seatbelts and airbags.

Safety Structure

The strongest steel safety cage yet built by Saab is designed to protect the passenger compartment. It is fabricated from high strength steel with most sections completely closed for additional strength and all joints designed to help prevent tearing under severe impacts.

The front and rear crumple zones are made up of carefully shaped steel members designed to absorb, distribute and deflect as much impact energy as possible, effectively shielding the passenger compartment.

Three distinct load paths on each side of the front structure channel impact forces through the front sub-frame, along the longitudinal members and through the upper rail. The longitudinal members have large sections that extend right through the floor of the car to the rear seat.

The three load paths are connected transversally via cross-members, the most important of which is the bumper beam. This is made from boron alloy steel with very high yield strength of 900 Newtons per square millimetre.

This highly effective design is a development of the system first seen on the Saab 9-5. The beam spreads impact forces across the front structure, allowing a controlled and predictable deformation almost regardless of the point of impact. In this way, the front structure of the all new Saab 9-3 is more compatible with other vehicles.

For side impact protection, Saab engineers have developed the B-pillar, side sills and door beams to behave as a single, integrated structure, deforming in a controlled and predictable way. A key part of this strategy is the �pendulum� movement for the B-pillar, a concept also used on the 9-5.

In effect, the B-pillar is hinged from the roof rail of the safety cage. It has highly strengthened upper and middle sections so that, in an impact, it is designed to bend inwards at the bottom, deflecting lateral forces downwards towards the floor, away from the more sensitive occupant head and chest areas. The door beams support this structure and the bottoms of the doors also interlock with the reinforced side sills so that the whole side structure plays a load-sharing role.

The door beams also have a major load-carrying function in side impacts with narrow objects, such as a tree, when the B-pillar is not engaged.

At the rear, two more longitudinal members are designed to buckle and deform downwards in a two-phase action. In rear end impacts, they dissipate impact energy towards the lower C-pillar area and at the same time also force the spare wheel, mounted flat in the boot, to rotate to a more vertical position for additional rear passenger protection.

The fuel tank is, of course, mounted low down in front of the rear axle, as far away as possible from any point of impact. Saab has extensive experience in working with safety regarding fuel system integrity and has its own very tough in-house requirements.

Second Generation Saab Active Head Restraints (SAHR)
Saab crash investigation findings, as published last year in the US Journal of Trauma, have already demonstrated the effectiveness of the innovative Saab Active Head Restraints (SAHR). There was a 75 per cent reduction in severe neck injuries when comparing Saab cars fitted with the SAHR against those not having the system.

Now Saab has developed a second generation version for even faster activation in rear impacts at lower speeds. The head restraint is activated as soon as the lower back is pressed into the seat-back by the occupant�s inertia during a rear impact.

The restraint is fixed to the top of a frame inside the seat-back which pivots at its mid point. As the occupant�s lower back comes into contact with the bottom of the seat-back, the upper half of the frame carrying the head restraint moves forward in the opposite direction. In this way, the occupant�s head movement during a rear end impact is minimised, helping to prevent neck injury.

The SAHR system is entirely mechanical and after activation the restraint automatically springs back to its passive position ready for further use. It is designed to give adequate protection, even if the adjustable restraint is set at an incorrect height, although for best protection it should always be adjusted to the prescribed height.

Roof Rail Airbags

The all new 9-3 is the first Saab to incorporate a roof-mounted airbag, which plays an important function throughout an entire crash sequence and, for additional head protection, is programmed to deploy in severe frontal as well as side impacts.

The Roof Rail Airbag is installed from the A to the C-pillar, up in the interior headlining above the side windows, and offers head protection to both front and rear seat occupants. To improve cushion kinematics during inflation, it is activated from the B-pillar area. The airbag remains inflated for up to three seconds in order to help prevent a passenger�s head, striking the A, B, or C-pillar or exterior objects, during the course of an impact sequence.

In side impacts, it is activated together with seatbelt pre-tensioning and the seat-mounted thorax side airbag. And in an industry first, it is also deployed in severe frontal impacts where stage two activation of the front airbags is required.

For improved impact sensing there are now two side impact sensors in each side of the all new 9-3, one in the sill near the B-pillar and the other in the lower part of the C-pillar. These sensors measure acceleration rates and a decision on airbag deployment is taken by the central sensing and diagnostic module (SDM) in a matter of a few milliseconds.

Adaptive Front Airbags

Dual stage, front airbags are introduced for a more occupant-friendly deployment in frontal impacts.

Two sensors in the front bumper beam detect impact severity, a sensor in the seat track communicates seating positions and a switch in the seatbelt buckles indicates whether or not the belts are being worn. All this data is sent to the centrally located SDM, which within milliseconds, chooses between activation of the belt pre-tensioners alone, or in combination with a single or two stage inflation of the airbags. In a severe impact, where stage two of the front airbag is used, the roof rail airbag will also deploy for additional head protection.

A crash with a relatively low level of impact energy would, for example, require less airbag pressure and, therefore, a slower rate of inflation than a more severe, high energy impact. Likewise, a short driver sitting close to the steering wheel or a front passenger sitting close to the fascia would also benefit from a softer, lower pressure inflation.

Conversely, if the occupant is not wearing a seatbelt, the system also takes this into consideration. In this way, the airbags can be deployed differently for the driver and passenger, depending on their requirements.

Seatbelt Load Limiter and Reminder system

Seatbelts are still, despite the use of airbags, the single most important occupant restraint system and three-point belts are, of course, used on all seating positions.

For all outboard occupants there are belt pre-tensioners and load limiting functions to remove belt slack and reduce belt loads in severe crashes. The pre-tensioner is mounted on the belt retractor and is activated by a signal from the airbag sensing system, igniting a small pyrotechnic charge which retracts the belt.

The load limiting function consists of a torsion bar inside the retractor that, at a pre-determined load level, will start to deform and thus reduce the belt load.

Saab has used a seatbelt reminder function since 1974 and to further inform customers of the importance of belt usage, a more advanced system is now introduced. This independently informs and reminds the driver and the front passenger of a non belt usage, using tell-tale and warning chimes, based on speed and time.

Occupant-friendly interior

A great deal of experience has gone into ensuring the interior surfaces and materials are occupant-friendly in the event of a heavy impact or rollover. In particular, the front areas of the cabin near the knee and lower leg, the headlining and all pillar linings are well bolstered to help prevent occupant injury.

In the foot area, protective padding reduces the risk of foot injuries and the driver�s pedals are programmed to collapse in a severe impact. The steering column and steering wheel are, of course, energy absorbing.

Passenger safety is the main reason why door armrests and inner door handles are always recessed inside a Saab and it is one of the reasons why the all new 9-3 retains a Saab tradition in having a floor-mounted ignition switch, well away from sensitive knee and leg areas.

Another Saab tradition in passenger safety is the importance of ensuring good protection against the hazard of shifting loads and the split-fold rear seatback has been carefully engineered for exceptional strength. Robust �tie-down� loops are also fitted as standard to the floor of the boot.

All New Saab 9-3 In Focus � Non-stop, stop lights!

If one of the rear stop lights fails, driving safety will be not be affected thanks to a dual function built into the rear lights.

The stop light function � extra light intensity whenever the brake pedal is pushed � is programmed into the outer of the two light bulbs in each rear light cluster. If this bulb fails, the brake light function is not lost because it is automatically switched to the other bulb. This is possible because the usual voltage restriction (13.3 > 6.3v), which is lifted whenever the brake pedal is pushed, is applied to both bulbs. Normal service is automatically resumed when the broken bulb is replaced.

Security and Comfort
A Secure and Comforting Experience

"For today�s customers, good car security is almost as important as safety. We have now taken the opportunity to arm our car with the sort of safeguards that tell any would-be thief ? don�t bother."
Lars Evensson, Project Leader � Security.

All New Saab 9-3 Highlights:

 

Most secure Saab ever
Highly rated by Insurers, including the NRMA
Sophisticated immobilisation, anti-theft and alarm systems
Vast array of useful comfort and convenience functions as standard

 

The all new 9-3 is, quite simply, the most secure Saab ever built. Its defense system enlists an arsenal of anti-theft devices that includes all practical technology that is currently available. Security is focused on preventing the car being stolen or having items taken from it.

With security comes comfort, and there are also a host of features to ensure the all new 9-3 is easy, convenient and rewarding in every day use.

Highly rated by Insurers

Representatives of leading insurance companies in Sweden and around the world � including the NRMA from Australia � have been consulted throughout the development of security systems for the all new 9-3. They were asked what they believe to be the most effective measures available, as well as examining and assessing the car�s security performance. While the results of these tests remain confidential, Saab is confident that such close liaison with insurance industry experts will contribute to highly competitive insurance groupings and reduced insurance costs for owners.

Anti-Intrusion Measures

The front passenger door is fitted with a freewheeling lock cylinder, which will immediately disengage from the door unlocking mechanism if any device other than the correct key is inserted. Efficient shielding of the locks inside the doors also prevents tampering with specialist tools, and the use of deadbolts for all four doors makes it virtually impossible for a would-be thief to forcibly break in.

Even if a thief were to gain entry, there would be little point in removing any of the car�s infotainment systems. Apart from being uniquely designed to fit only a Saab car, they are electronically married to their original host car. They could only function in another Saab after being re-programmed at a Saab dealer.

New for Saab is the security marking of a large number of major components to enable the police to trace them back to the car if they are recovered following a theft.

Anti Car Theft
To prevent the car itself being stolen, the immobiliser system uses both an electrical steering column lock and disablement of the engine management system.

When the ignition key is inserted in the floor-mounted switch, a transponder sends a signal to a control unit in the module which then communicates with all systems in the car through the central integrated control module. The start message is encrypted in a complex, rolling code from the key�s transponder which would take an estimated eight years to decipher in the unlikely event that a would-be thief could make the correct electronic connections.

Further measures have also been taken to combat the so-called professional thief. Barriers, or firewalls, have been put in place to protect the car�s electronic systems from digital intrusion with illegal scanning devices.

As the car�s original key is such a vital component in the chain of security precautions, confidential measures are put in place at Saab dealers to ensure there is no fraudulent issue of a replacement or duplicate key.

Alarm system

As a further back-up to the car�s perimeter security features, an advanced alarm system is standard on Aero and optional on Linear, Arc and Vector.

The alarm system incorporates a siren and flashing lights to discourage anyone from entering or trying to move the car.

The alarm will be activated if any illegal attempt is made to open the bonnet, boot lid or any of the doors. A �tilt� sensor will also sound the alarm if the car is lifted in any direction, such as during an attempt to tow it away. Inside the car, an extremely sensitive ultrasonic beam will detect any movement, including pieces of flying glass or an arm reaching inside following a break-in.

A further refinement is the use of a separate battery to power the alarm system. This is hidden in the car to prevent illegal tampering and prevents a thief from disabling the alarm by disconnecting the car�s main battery.

For greater personal security, the car�s alarm can also be activated by pressing a �panic� button on the car�s Electronic key, or by pressing the interior central locking button on either front door.

Smart door mirrors

Ever folded in the door mirrors and then forgotten to reposition them until you are back in the car? An annoying oversight that can�t happen in the all new 9-3. The electrically-operated mirrors are linked to a speed sensor and will automatically fold out once the car exceeds 50 km/h. This electronic fold out feature is standard on Aero.

A typical Saab innovation is the button for tilting the mirrors down. This function normally operates automatically when reverse gear is engaged. But it can be just as useful to tilt a side mirror when going forwards, following a kerb or low wall, for example. A push of the button gives this choice in the new 9-3.

Remote window and sunroof operation

In some circumstances it can be useful to remotely close or open the windows, even the sunroof, after leaving the car. This can now be done simply by holding down the lock/unlock button on the remote control unit.

This remote function also makes it possible to close a window or sunroof that has been inadvertently left down, as well as serve as a final check that the windows are fully closed. Likewise, the windows and sunroof can be opened, or set to a desired position, to let heat out of the car. This feature is standard on all models.

Automatic disconnect/connect fog lamps

To prevent the rear fog lamp being inadvertently left on when no longer required it is automatically disconnected when the ignition is switched off. However, both front (where fitted) and rear fog lamps do not have to be switched on again if the engine stalls because they are programmed to remain live for 30 seconds after the ignition is first switched on. This is standard on all models.

Variable speedometer illumination

The �Night Panel� feature allows all main dashboard illumination � except for the speedometer � to be switched off when driving at night. The Profiler function also enables the driver to restrict illumination of the speedscale to the range, 0-90 km/h. It will, of course, automatically illuminate if these speeds are exceeded. This is standard on all models.

Variable heating for the front seats

The thermostat for the heated front seats can be set at one of three temperatures (42, 37 or 33°C) by simply pressing the relevant button once, twice or three times. The setting can also be permanently stored via the Profiler function. This is standard on all models.

�Intelligent� windshield washing

When the windshield is washed at speeds under 20 km/h, the wipers will automatically make an additional sweep after an eight second delay in order to clear the windshield of residual streaks. This is standard on all models.

Washer fluid saver

When there is less than one liter of fluid left in the washer reservoir, the headlamp washer function will automatically de-activate in order to prioritise washing of the windshield. This is standard on all models.

Vertical wiper parking

If you want to cover the windshield � to prevent frosting up when parking outside or to help keep the interior cool in hot weather � the wipers can be parked in a vertical position by removing the key fob and pressing the control stalk once. This is standard on all models.

Automatic air recirculation

To avoid the unpleasant smell of detergent in the windshield washer system entering the interior, the air conditioning can be programmed (through an authorised Saab dealer) to briefly switch to �recirculation mode� whenever the driver operates the washer system via the stalk control. This is standard on all models.

Halo lighting

When approaching the car, a simple blip of the remote control on the Electronic key will turn on the exterior and main interior lights as a �lead-me-to-the-car� function. With a range of up to 20 meters, this facility can help identify the car at night in a crowded car park, illuminate the immediate surroundings and discourage anyone from attempting to enter the car when it is being opened. This is standard on all models.

Welcome lighting

A warm welcome always awaits the driver courtesy of automatic soft footwell lighting, with �theatre� dimming, and �puddle lights� in the bottom of the front doors to illuminate the ground outside. Likewise, at night the main interior light will switch on when the ignition key is removed so the driver or passengers are never left completely in the dark. This is standard on all models.

Follow-me-home lighting

When leaving the car at night, a tweak of the lights stalk will keep the headlights on for 30 seconds. A useful aid for walking up the drive to the door or when parking in unfamiliar ground. This is standard on all models.

The all new Saab 9-3 Sport Sedan is the first step in the biggest product development program in Saab�s history. It spearheads the arrival of an entirely new family of cars, each focused on meeting the particular requirements of a different niche in the market.

As Saab�s first contender in the premium, compact Sport Sedan segment, the all new 9-3 is dedicated to delivering a unique, �fun to drive� experience that promises to set new standards for the class.

The coupé-like silhouette, with steeply raked windscreen and rear window and short front and rear overhangs, communicates a strong, sporty stance, reinforced by negative wheel cambers.

The overall look is designed to convey a sense of forward movement. The wedge-like profile also combines with the integrated headlights and grille to give the all new 9-3 its distinctive Saab identity.

Excellent aerodynamics � including a highly competitive 0.28 Cd drag coefficient � result in low lift forces at the rear axle to improve high speed stability and braking. Careful airflow management also benefits the driver by helping to prevent road grime building up on the rear window and lights.

The all new Saab 9-3 comes with a brand new, 2.0-litre, all-aluminium turbocharged engine offering three levels of performance. The emphasis, as always from Saab, is to deliver significant torque for safe and sporty driving. The engine is available with maximum power and torque outputs of 110 kW / 240 Nm, 129 kW / 265 Nm, and 155 kW / 300 Nm.

The front-drive transmissions include five and six-speed manual gearboxes and a five-speed automatic with Saab Sentronic semi-auto selection.

The all new Saab 9-3 is offered in three forms � Linear, Vector and Arc; plus a high-performance Aero model.

Compared to its predecessor, the all new 9-3 offers more spacious accommodation, particularly for rear seat passengers, within the same overall length. Wheelbase is 70 mm longer and the front and rear body width is increased by 55 mm.

The all new Saab 9-3 is priced and specified to compete strongly against key rivals such as the BMW 3-series, Audi A4 and Volvo S60.

Driver Involvement

The all new 9-3 has undergone the most extensive chassis development ever undertaken by Saab.

The handling of the car, its sensitivity to driver inputs and a high degree of feedback all combine to deliver a level of driving involvement and pleasure that challenges the class benchmark.

The main highlights include:

 

�ReAxs� passive rear wheel steer characteristic. The kinetics of the rear suspension are tuned for a unique rear wheel steer response for optimum handling and stability.

 

 

Four-link independent rear suspension. High lateral stiffness for stability and grip; longitudinal compliance for ride comfort.

 

 

Low mounted steering rack gives excellent feel and precision with progressive power assistance and fast responses.

 

 

Front suspension. MacPherson strut with hydroformed (hollow), rubber-isolated sub-frame. High lateral bushing stiffness for good steering response and precision; high longitudinal compliance for ride comfort.

 

 

Advanced chassis electronic systems. Saab-tuned �user friendly� ESP (Electronic Stability Program). Mechanical brake assist, EBD (Electronic Brake force Distribution), CBC (Cornering Brake Control) and TCS (Traction Control System) all standard features.

 

 

Minimised unsprung weight for better ride quality. Hub carriers and assembly and lower rear suspension links in aluminium. Anti-roll bars in hollow section steel.

 

Refined Performance

Saab is the center of expertise within General Motors for the development of turbocharged petrol engines. The new powertrain adds enhanced refinement and driveability to Saab�s traditional strengths of high torque for strong, mid-range pulling power. It also delivers a level of sporty performance in keeping with the chassis�s dynamics, further reinforcing the all new 9-3�s sharp driver focus.

The main highlights include:

 

New all-aluminium 2.0-litre turbocharged engine. Saab developed and tuned for 110 kW / 240 Nm, 129 kW / 265 Nm and 155 kW / 300 Nm. All internal components unique to Saab. Balancer shafts and dual-mass flywheel for greater running refinement.

 

 

Sophisticated powertrain performance. Saab�s new in-house 32-bit Trionic 8 engine management system allows precise throttle control, adaptive torque delivery and smooth power on/power off characteristics.

 

 

More transmission choice. Uprated five-speed and all-new six-speed Saab manual gearboxes. Five-speed, adaptive automatic transmission with Saab Sentronic semi-auto gear selection.

 

 

Unique �pendulum� engine mounting. Engine noise and vibration is reduced by installation of rods at the base of the engine for optimal torque control.

 

Driver Adaptability

In addition to its driver-focused chassis dynamics and powertrain performance, the all new 9-3 is also designed to adapt to a wide range of driver needs, establishing a close interaction with the driver.

Main highlights include:

 

�Profiler� customisation. A wide range of functions can be pre-set according to personal preference, including, where fitted: anti-theft alarm, parking assistance, rain sensitive wipers, stereo and automatic climate control.

 

 

Advanced electronics. Most extensive automotive systems use of fiber optics. With a signal capacity 50 times greater than conventional wire circuitry, fiber optics provide a high speed platform for advanced in-car �infotainment�.

 

 

Integrated Bluetooth?* application. Bluetooth wireless technology enables short-range communication between devices such as telephones, PDAs (Personal Digital Assistants) and computers. The all new 9-3 supports hands-free voice control and calling via a Bluetooth headset, as well as wireless dial-up networking functionality using a Bluetooth PDA or laptop.

 

 

Four specification levels. Linear is modern and understated with woven textile interior and anthracite trim. Arc adds 16-inch alloy wheels and rucched leather interior with poplar wood trim. Vector has 17-inch alloy wheels and a sports leather/textile interior with matt chrome trim. The Aero variant is the performance flagship of the range with lowered, sports tuned chassis and body styling, full leather trim and available exclusively with the 155 kW engine.

 

 

Additional load-carrying potential. A standard 60/40 split fold rear seat with ski hatch allows occasional extra cargo to be effortlessly carried.

 

 

Host of comfort features. Designed to make living with the all new 9-3 as convenient as possible, these include: door mirrors that automatically reposition after being folded; a remote window and sunroof operation and �halo� perimeter lighting at night.

 

 

Intelligent Dual zone air conditioning with automatic balance control that senses changes in sunlight or shade outside the car and automatically adjusts airflow to keep interior temperature constant.

 

 

Lower running costs. Longer service intervals and reduced workshop times reduce scheduled servicing costs by 30 per cent, compared to previous model. On-board algorithm adapts oil change cycle to how car is used.

 

Built Around the Driver

In common with all Saab cars, the all new 9-3 is built from �the driver outwards�. That means the cabin ergonomics, the instrumentation, the controls and the seating position are all developed from the driver�s perspective.

Main highlights include:

 

Cockpit feel. The main instrument panel wraps around the driver. Logical layout and tactile feel to controls. Green instrument illumination and Night Panel function for restful night driving.

 

 

High position display. Saab Information Display (SID) located on top of the fascia near the base of the windscreen, close to the driver�s natural field of vision. Screen shows satellite navigation directions and incorporates Saab Car Computer.

 

 

Structural strength. With a torsional rigidity of 22,000 Nm/degree of deflection, the bodyshell is more than twice as stiff as its predecessor�s. This contributes to outstanding ride and refinement, handling and safety properties.

 

 

Designed for Real-life Safety. 75 crash configurations carried out during development, utilising Saab�s 6,000-strong database of real-life road accidents. Tests include truck-to-car side impacts, car-to-car frontal impacts with a closing speed of 120 km/h and replica moose impacts.

 

 

Second generation Saab Active Head Restraints (SAHR). Pioneered by Saab, these help prevent neck injury for front seat occupants in rear-end impacts. Now improved for even quicker action.

 

 

Integrated safety features. Seat belt pre-tensioning and load limiting for all outer seating positions, combined with dual-stage front airbags, seat-mounted side airbags and side roof rail airbags.

 

Announcing the arrival of the all new Saab 9-3 in Australia and New Zealand, Tony Jennett, Saab Automobile Australia Managing Director, says: " The all new 9-3 gives Saab a strong competitor in the premium, compact sport sedan segment. It is a dynamic car that blends a fine-handling chassis with a new, refined powertrain for a �fun to drive� experience.

"This stylish car will appeal to young, premium car buyers who place a priority on a rewarding driving experience but also want to express their individuality through choosing a distinctive, less obvious brand."

Body, systems and lighting
Firm Foundations

"This is the strongest structure we�ve ever produced. It is was developed in close co-operation with the design, chassis and safety departments who all had their own specific requirements ."
Kerry Andersson, Project Leader, all new Saab 9-3 body in white.

All New Saab 9-3 Highlights:

 

New standards in torsional rigidity � more than double its predecessor
New joint technique adds strength
Second-generation �crash boxes� prevent body damage
Aluminium bonnet
Unique halogen headlamps
Bi-xenon headlamps
Powerful screen washing system

 

The body structure of the all new 9-3 is the stiffest yet produced by Saab engineers and it is the solid foundation on which the car�s exemplary handling, ride and safety characteristics are built.

The use of high-grade steels, tailored blanks, laser welding, galvanising of all external components and advanced joint techniques has produced an extremely strong and durable body. Effective �crash boxes� in the front bumper help to minimise body damage in impacts up to 15 km/h.

The power of the lighting system, which includes the availability of bi-xenon headlamps, is in the fine tradition of Saab cars, as is the efficiency of the windscreen wipers and washing systems.

Structural Benefits

An exceptional level of structural stiffness was an essential requirement in the design of the all new 9-3. It is high torsional rigidity that helps give that reassuring solid feel, which is communicated every time a door is closed or the car negotiates a poor road surface. And it makes a major contribution to eliminating squeaks and rattles, vibrations and resonance.

A stiff body is also a prerequisite for the work of chassis engineers. The car�s handling can only be effectively honed through its suspension and steering if the structure on which all these components exert loadings is solid and predictable.

Finally, and arguably most importantly, the car�s ability to withstand a heavy impact is largely due to the strength of its passenger compartment and the ability of the structure�s crumple zones to prevent energy reaching it.

Structural Strength
A four-door sedan body is inherently stronger than a five-door hatchback format because there is no large rear tailgate opening. This feature, and advances in technology, contributes to the exceptional torsional rigidity of the all new 9-3. At 22,000 Nm/degree of deflection, it is more than double that of its predecessor. To put that figure in perspective, the body structure is as strong as a meter long rod fixed at one end would need to be if it was supporting the weight of a fully-laden large car � or a small elephant � at the other end.

The Saab design team has adopted unique bracings above the rear wheel housings to provide a structure that is more than a match for premium class competitors, despite some potential loss of stiffness through having the versatility of a split/fold rear seat.

While 59 per cent of the all new 9-3�s body weight is composed of high strength or ultra high strength steel, a far more important consideration is how all the elements � 332 structural body parts are used in the new 9-3 � are connected. In other words, how they interact in sharing the load-bearing task. The strength of a good design is far more than simply the sum of its parts.

The body of the new 9-3 is essentially a monocoque construction fabricated from beams and pressings. Saab structural engineers have used CAD techniques and finite element data models with a resolution of up to 500,000 cells representing the new 9-3�s structure.

Special attention was devoted to the design of seams and joints. It is pointless using high strength steels for different sections if the technique used to join them together is not at least as strong. For example, there are no joints at all at any of the corners of the safety cage, where stresses are likely to be greatest. Instead, joints between beams are carefully welded in place with overlaps of at least 20 mm on straight sections.

In order to be sure that extra strength does not necessarily mean extra weight, Saab engineers have made great use of new technology in using �tailored blanks� for large structural components. For example, the two main bearers which extend from the front of the car to the rear bulkhead are made from pressings of high strength steel. These are produced to different thicknesses, according to the localised loading demands at any point in the car�s structure. In other words, the extra strength or weight is located only where it is required.

Outer Body

Both front and rear bumper assemblies are designed to be �self-repairing�, in that they can absorb impacts up to 8 km/h, minimising damage and the need for repair. The bumper skin is simple and quick to replace after a minor collision, making it a very practical benefit in minimising the nuisance and cost resulting from minor bingles in supermarket car parks.

For higher speeds, Saab was first to introduce deformable crash boxes behind the front bumper on the second generation Saab 900 in 1993. These are intended to absorb and contain relatively low speed impact forces in order to prevent damage to more expensive bodywork components.

Other manufacturers have now adopted crash boxes and in the all new Saab 9-3 the technique is perfected still further, with no less than 103 computer simulations carried out to ensure their effectiveness.

The finished crash box design is a hexagon shape with a conical profile and concertina sections that will protect the structure of the car, including its front body panels, from damage in impacts up to 15 km/h. The boxes are now also bolted, instead of welded, to the front beam to make their replacement even easier.

Where there are no structural demands, Saab engineers were able to consider the further use of weight-saving materials. For the all new 9-3 they have adopted aluminum for the bonnet, saving 50 per cent, or nine kilos in weight, compared to steel. The aluminum bonnet is also slightly stiffer and more resistant to dents.

The design of the boot lid was also the subject of detailed research and the solution adopted is typically Saab. For users of the all new 9-3 to be able to exploit the load carrying capabilities of a 60/40 folding rear seat, it was important that boot opening was as large as possible. That is why the design team chose �swan neck� hinges for the one-piece boot lid.

The use of a more conventional strut and multi-link pivot arrangement would have resulted in an unacceptable 15 per cent reduction in opening width, equal to 10 cm. The spring-loaded swan-neck hinges, in fact, give an even easier, almost weightless opening and closing action.

The doors are inset-mounted, as part of the monoside body pressing. With substantial ultra high strength steel reinforcements, they play an important role in occupant protection. A particular feature of note is the way the bottom edge of the door frame overlaps and interlocks with the strong, reinforced side sills. This allows the doors to spread heavy impact forces by enlisting the support of stronger sections of the body.

Superior Lighting

The strong lighting performance of Saab cars is almost as widely acclaimed as their reputation for safety. Hardly surprising, as good night-time visibility is, of course, an essential element of driving safety.

The headlamps of the all new 9-3 are a new integrated design, protected by clear plastic lens covers which are lighter and less prone to stone chips, cracking and condensation than glass.

The headlamps standard on Linear, Arc and Vector use halogen bulbs behind projector units for excellent illumination. In order to meet demanding Saab requirements, the reflector surfaces are uniquely made by the supplier, Hella, from magnesium, instead of the commonly used steel, which allows more complex shaping for better lighting performance.

Customers can also go one step further by specifying exceptionally powerful bi-xenon lights, an option for all variants but standard on Aero.

These gas discharge bulbs give an extremely bright, much whiter light than halogen units. Saab is among the first manufacturers to offer this technology for both dipped and main beam � hence the term, bi-xenon. Where a normal halogen bulb will emit 1,500 lumens of light, a xenon unit will give 3,200 lumens � more than twice as much power � while giving a spread of light that is also 60 per cent greater.

The effective control of such a powerful beam is essential for the benefit of fellow road users, as well as the driver, therefore bi-xenon lights have a dynamic, self-leveling function as standard. Under acceleration or braking, sensors detect body motion at the front of the car and electric motors in the headlamp units automatically adjust the height of the beam to compensate for any changes in vehicle attitude.

The performance of the headlamps, no matter how powerful, is badly compromised if the lens become caked in grime. For the all new 9-3, powerful spray jets, working at 3.5 bar pressure, keep the plastic units clean. These automatically retract when not in use.

At the rear of the car, the single fog light automatically disconnects when the ignition is switched off, an added precaution to prevent it being inadvertently left on when no longer required.

The high level rear brake light is now an LED unit, as tests show this illuminates more quickly than a conventional bulb to give a more efficient warning signal.

Cleaning power

Keeping a clear windscreen is vital for driving safety and the large wipers are linked to a powerful battery of three pairs of washer jets, all working at 3.5 bar pressure, twice the power of other systems on the market. It is cleaning power designed to shift the most stubborn of deposits.

The wipers are two speed with an infinitely variable intermittent wipe. Automatic rain-sensing operation including driver adjustment for sensitivity is standard on all models.

In true Saab tradition, the five liter washer reservoir is exceptionally large, with two liters more capacity than normal. User trials show that jets working at such high pressure do not, in fact, require more washer fluid because they are generally used in shorter bursts.
