The front-end styling deliberately echoes design elements of the Audi Nuvolari quattro coup study, thus emphasising that this model also belongs to the same family as the other new Audi models the A8 6.0 quattro, A6 and A3 Sportback: a new Audi generation. The formal idiom of the Nuvolari quattro can also be found at the rear end where the low-positioned two-piece light units, which also arch a long way inwards, emphasise the horizontal design of the vehicle body. The saloon and Avant both sit squarely on the road, the voluminous bottom section and very flat window area combining to produce sports car proportions. A clearly crafted horizontal light-refracting edge gives the bumpers additional shape. No less eye-catching at the rear end are the exhaust tailpipes which are now 10 millimetres larger at 80 millimetres a clear indication of just what the new A4 models engines are capable of. The side panel sections under the window area are also a completely new design on both the saloon and Avant. The gently rising arch of the shoulder line begins above the front mudguard and runs along the side of the body as a light-refracting edge. It finally merges with the rear lights where it is continued in their upwardly arching top edge. Proportions of the kind typically found on sports cars are the characteristic feature of the side design: high body panels and a flat window area. Another sign of the family resemblance that the new A4 has with the Nuvolari quattro study and also the current Audi A6 is the striking but ever-discreet dialogue of concave and convex arches, of curved surfaces facing towards and away from the light. The result is an extremely stimulating interplay of light and shadow, giving the car its own very special appeal from every perspective.
The interior The perfect tailor-made suit: a metaphor frequently used to describe vehicle interiors. But this image will come to the mind of anyone getting behind the characteristic wheel of the new Audi A4, with its hallmark feature of the singleframe element at the centre. This, after all, is a car that unites two apparent opposites to produce an amazing synthesis of exceptional ergonomics and subjective comfort. On the other hand, the new A4's cockpit is characterised by lines extending a long way into the door trim and centre console areas, which quite literally appear to embrace the driver. This "wrap around" effect, to use the designers' technical term, is accentuated additionally by the A4's high waistline. This feature is something that many customers value very highly, not least because of the remarkable sense of security that it imparts. The architecture of the dashboard and centre console also provide scope for positioning a wide range of instruments and controls high up, in other words ideally within the driver's field of vision. This is an ergonomic strategy that is adopted in every aircraft cockpit for very good reasons. The lines of the driving area create a lively interplay of distinctly rounded, tangible shapes and graphically clear edges and notches. This area is thus divided up into clearly defined zones. These can be distinguished at a glance a worthwhile ergonomic bonus that speeds up intuitive access to the individual information units and function groups. This process of locating involves both the visual and tactile senses: groups of controls and displays can also be identified by the materials used. As far as the instruments are concerned, the most important information elements are located under a dome-shaped cover. The dial graphics of the large round

The rear seats have much more the character of individual seats than of a conventional bench-type seat. This not only enhances the interior's sporty looks, but also makes for improved long-distance comfort for the occupants of the two outer seats. There is also more room than average for luggage in the A4 saloon: with a capacity of 460 litres, the smooth-floored luggage compartment is well-equipped for tackling challenging transport tasks. And with a vast 1,000 millimetres between the wheel arches, there is plenty of room even for bulky loads. A4 Avant: the load area The A4 Avants load area combines an exclusive atmosphere with optimum utility and variability. This synthesis of successful interior design and multifunctionality sets new standards. A variable load-area floor provides generous storage capacity. With three different floor-panel positions, the load area capacity is between 377 (floor closed), 422 (floor partially open) and 442 litres (floor removed). The maximum storage capacity with the rear seat folded is 1,184 litres. Loading heavy and bulky objects into the car is simplified considerably by the low height of the load-area floor level with the sill. This means that objects up to 1,000 mm wide can be loaded through the tailgate opening. The smooth-surfaced inner side panels have no bulges, making the load area look extremely tidy at all times. The available capacity can be used efficiently, with neither edges nor
projections in the way. Even in its standard version, the A4 Avants load area offers a full range of ingenious details such as a net for small items, chrome-plated load-securing lugs, a storage compartment behind a cover in the left side panel, an easily accessible 12V power socket in the side panel and an active light in the tailgate that also illuminates the area behind the vehicle.
The load-area floor is at the same height as the folded rear seat backrests, thus guaranteeing an almost level luggage area. The luggage cover and the dividing net are located in a special compact, space-saving housing. This combined housing is attached to the wider part of the rear seat backrest and folds forwards with it to make the maximum storage space immediately available. In this position, the housing can easily be removed through the rear side door. The load-area floor forms a second level in the luggage area. It is not rigidly fixed in the vehicle, but can be folded. This means that its position can easily be changed, making a useful contribution to the load areas unique variability. Under the floor there is an easy-to-clean plastic tray attached to the body which can be used as an additional storage compartment or combined with the total luggage capacity. An optional reversible mat including fold-out bumper protection protects both the bumper and the load itself. The tailgate opens automatically up to an overall height of 1.98 m. Two handle recesses on the left and right inside the tailgate handle height 1.83 m allow it to be pulled shut from any position. A load-area package with practical detail solutions for numerous situations is available as an optional extra. A bag hook and a luggage net to prevent objects

FSI engines develop more power and dynamism than conventional units with indirect fuel injection and they do so with a very high standard of fuel economy. With the increase in efficiency achieved here, Audi has opened up a new dimension in the efficiency of standard spark-ignition engines and once again demonstrated the proverbial progress through technology familiar to the brand. FSI direct petrol injection has confirmed its unique potential several times over in what must be the most challenging endurance test in the world: an engine with FSI direct injection powers the Le Mans-winning Audi R8.
How does the FSI technology differ operationally from a conventional engine? The term "petrol direct injection" makes the central feature clear: in contrast to indirect injection, the fuel is injected directly into the combustion chamber. A common rail high-pressure injection system with a newly developed singlepiston high-pressure pump operating on demand ensures exactly the right supply of fuel, delivering precisely the volume required for building up operating pressure between 30 and 110 bar. In the intake tract, also comprising the two-stage variable intake manifold, moving charge-movement flaps provide the necessary tumble effect, swirling the induced air around depending on operating point. In order to achieve the high specific power and torque values, a new combustion process has been developed. This has the potential for worldwide application and for operation on the fuel grade RON 95/91. Together with the optimum geometry of the combustion chambers and the dosage of fuel injected with supreme accuracy down to the last millisecond, this allows a significant increase in compression: While conventional production engines generally have a compression ratio of not more than 10.5:1, the compression ratio on Audi's 3.2 FSI power unit is 12.5:1 a record on production cars and the essential prerequisite for the new engine's high standard of efficiency.
New base engine Completely new in its design, the 3.2-litre V6 has been developed with the specific goal of maximum space efficiency: measuring only 360 millimetres in length and 430 millimetres in width, and weighing a mere 169.5 kg thanks to the use of aluminium, the engine offers significant benefits in terms of driving dynamics.
Like on Audi's new V-configuration engines in general, the cylinders are arranged at an angle of 90o and the distance between cylinders is 90 millimetres. Cylinder bore of 84.5 millimetres and cylinder lift of 92.8 mm add up to an overall engine capacity of 3,123 cc. The four-valve cylinder head with a side opening for the injection valve is another special feature designed specifically for this 3.2-litre power unit. Both the inlet and exhaust camshafts come with variable adjustment to ensure optimum results, in terms of both maximum output and an extremely broad peak-torque range. The camshafts, oil pump and balancing shaft are all driven by four-piece chain drive of the same type as in the 4.2-litre eight-cylinder unit. Emissions control in the 3.2 FSI is optimised by two ceramic catalytic converters positioned close to the engine. As a result, this high-performance power unit easily undercuts the EU4 emissions standard. Fine-tuning of the exhaust system offers the driver yet another bonus: the distinctly sporty but never irritating sound of a genuine six-cylinder unit, making the qualities of the engine a truly sensory experience. The Audi A4 3.2 FSI with front-wheel drive is available with the continuously variable multitronic transmission. On the model with permanent quattro fourwheel drive, a 6-speed manual gearbox is responsible for regulating torque and power. The 6-speed tiptronic with sport program is also offered as an alternative for quattro models.

The 1.9 TDI One of Audi's most successful and most-built engines is also to be found in the new A4: the four-cylinder 1.9-litre TDI with pump-injector direct injection. The latest version develops 85 kW (115 bhp) and produces an impressive 285 Nm of torque at just 1,900 rpm.
The A4 1.9 TDI takes just 11.2 seconds to pass the 100 km/h mark. And with a top speed of 201 km/h, the entry-level TDI model is the ideal car for long stretches on the motorway at high average speeds. Especially as the fuel consumption of around only 5.6 litres per 100 kilometres means that a distance of over 1,000 kilometres can be covered between stops for refuelling. This once again demonstrates the superior maturity and efficiency of TDI technology in conjunction with the pump-injector unit. Indeed, this system is still able to provide the highest level of injection pressure of up to 2,050 bar the weight of a car on an area as small as a fingernail. This high pressure assures ultra-fine atomisation of fuel within the combustion chamber, thus providing excellent thermodynamic efficiency. On the road this means outstanding fuel economy and, at the same time, a high torque yield. And thanks to pilot-injection control, the performance spectrum of a pump-injector engine includes good engine acoustics and efficient emissions control. This likewise applies to the 1.9 TDI, which easily undercuts the EU4 emission limits. The A4 1.9 TDI is available in combination with a 5-speed manual gearbox.
Transmissions The supreme fuel economy and dynamic performance offered by the new Audi A4 also results from the standard usage of 5-speed and 6-speed manual gearboxes
and 6-speed automatic transmissions with a wide range of gear increments. The current generation of the continuously variable multitronic transmission now has seven predefined transmission ratios that can be preselected as an alternative. Ultramodern manual gearboxes The manual versions of the new Audi A4 come with Audi's new generation of ML transmissions, the abbreviation ML standing for Manual/Lengthwise. Featuring tight gear increments, this sophisticated gearbox of the latest generation combines extreme precision in shifting gears with short, clearly defined gearshift travel. Thanks to a special mount for the selector forks, the gear lever is effectively protected against driveline vibrations; the driver does not feel the gear lever trembling at all. Internal friction reduced by a series of measures increases the efficiency of the manual gearbox. This means that engine power can be converted even more efficiently into forward propulsion. The 6-speed tiptronic with sport program The 6-speed tiptronic transmission is available in conjunction with the very high-torque 3.2 FSI, 3.0 TDI and 2.0 T FSI power units featuring permanent fourwheel drive. Having already made its debut in the high-performance Audi S4, this transmission converts the power and muscle of the engine into a superior symbiosis of dynamism and operating convenience. Weight reduction, a fast and crisp gearshift, as well as an optimised gearshift strategy help to combine the superior convenience of automatic gearshift with the sporting performance so typical of the A4.

Compared with its 5-speed predecessor, the new 6-speed gearbox is 14 kilograms lighter, the overall weight of the transmission being a mere 115 kilograms. Again compared with a 5-speed automatic transmission, the overall spread of gear ratios is up by 18 percent on average. This means a much improved accelerating performance in the low gears and a clear reduction in engine speed and consequently a reduction in both noise level and fuel consumption at high speeds. The shifting speed of the new 6-speed tiptronic has also been significantly optimised. The driver benefits from more spontaneous gear changes particularly when downshifting. In addition, the fact that the engine automatically doubledeclutches further increases agility. Both in stage D and in the S sport program, the electronics respond efficiently to parameters such as lateral and longitudinal acceleration as well as to the movement of the accelerator pedal. This helps to prevent any unwanted upshifts when cornering. Continuously variable multitronic After making its production debut successfully in the year 2000, Audi's continuously variable multitronic automatic transmission is again offering its superior qualities in the new A4, combining the benefits of a manual gearbox with those of a geared automatic transmission. Fortes typical of multitronic are smooth but very dynamic acceleration as well as convenience in use and the efficient transmission of power. The high standard of operating convenience offered by multitronic exceeds that of a conventional converter-type automatic transmission, while in terms of dynamic performance and economy, multitronic can by all means be compared with a manual gearbox. If the driver wishes to actively choose the appropriate transmission ratio, he is able to do so at the gear lever or using the optional shift paddles on the steering wheel, now providing no fewer than seven predefined gear ratios.
Numerous reinforcements and adjustments, as well as optimised cooling, serve to significantly enhance the performance of Audi's continuously variable automatic transmission. The multitronic is now even able to convey torque of up to 330 Nm, and is thus the ideal partner even for the most powerful V6 engine in the series, the 3.2 FSI which develops an output of 255 bhp and 330 Nm of torque. Modified for the new Audi A4, the multitronic variator spans an even wider range of gear ratios: the overall ratio between the largest and the smallest gear transmission ratio is 6.25, virtually ideal for such a transmission. It permits dynamic, sports-style acceleration thanks to the use of lower ratios, but also fully exploits the engine's economy potential by using the highest ratio. A further special feature is the ability of the electronics to emulate the functions of a manual gearbox. Introducing the latest version of multitronic, Audi has opted for no fewer than seven forward gears activated by the driver using the selector lever by means of a one-touch function in the second shift plane or by pressing down the gearshift paddles on the steering wheel (optional). These seven gearshift stages are memorised by the system as fixed shift programs. Depending on which gear the driver selects, the controller is supplied with the ratio as a set point, which it establishes at the variator and maintains. Even these manually prompted gearshifts take place smoothly and jolt-free, satisfying the desire for sports performance. quattro permanent four-wheel drive quattro permanent four-wheel drive has long since been one of the favourite technical concepts of Audi drivers. Around 25 percent of all 2003 models of the Audi A4 were equipped with four-wheel drive; the figure will undoubtedly be higher for the new-generation model. Because right from the production start, Audi will be able to supply the engine versions of the new A4 from 120 kW (163 bhp) upwards as quattro models.

Its major strength lies in capabilities that have come to be regarded as a matter of course over the past 20 years: a persuasively superior dynamic performance and driving safety, and a distinctively superior form of travel. A vehicle with permanent four-wheel drive can translate significantly more traction and consequently higher cornering forces into propulsion. This in turn means greater driving enjoyment and safety for the driver. Improved directional stability, much lower susceptibility to cross-winds and better towing properties also characterise the superiority of the Audi A4 quattro. On the new Audi A4 quattro, with its longitudinally installed four-cylinder and six-cylinder engines, a Torsen centre differential automatically distributes power to all four wheels. This system is also used on Audi's highest-performance vehicles, the A8 as well as the 480 bhp RS 6 Plus, for example. The name "Torsen" is a contraction of the two terms "torque" and "sensing". The Torsen differential is a self-locking worm gear. The advantage is that the locking action is only prompted by the driveline. Yet this type of differential accommodates differences in speed when the brakes are applied and when cornering. Normally the power is split 50:50 between the two pairs of wheels, but in extreme cases the entire propulsive power can be diverted to either pair. In the event of more than one wheel encountering considerable slip, the electronic differential lock EDL can even concentrate this power on one wheel.
Sheer driving pleasure The dynamic chassis Dynamics and comfort, easy handling and active safety at the very highest level: on the basis of these strengths, Audi is also demonstrating its proverbial "Vorsprung durch Technik" with the new A4's dynamic chassis. Agility and ride comfort are equally impressive. This road behaviour is the result of extensive modifications in the area of elastokinematics as well as to the spring and shock absorber settings. The predecessors tried-and-test basic geometry has been adopted at both front and rear: four-link front suspension and the highly complex self-tracking trapezoidal-link rear suspension. Both consist primarily of light-alloy components resulting in a low unsprung mass. All versions of the Audi A4 have disc brakes at the front and rear; the front discs are ventilated. Their dimensions have been adapted to the increased performance potential of the new generation of engines. Excellent controllability, spontaneous response and above all considerably reduced braking distances are the result. The front suspension On the four-link front suspension layout, each wheel is located by four aluminium control arms. Large-volume rubber components are used as the damper mounts on

the new suspension design. This helps to effectively isolate the shock absorbers acoustically. Several mounts as well as the considerably stiffer track rods on the front suspension have been adopted from the high-performance S4. The mounts for the control arm originate from the new Audi A6. Together with the new shock absorber settings, this results in a particularly sensitive response to steering movements and even more precise feedback from the road. In other words, extremely dynamic behaviour which is isolated almost completely from front-wheel-drive influences.
High-tech rear suspension The new Audi A4 comes with one of the most complex, but also most efficient, rear suspension layouts currently available. The trapezoidal-link rear suspension makes for top-quality ride comfort on all models, coupled with dynamic behaviour that will amaze the driver of many a competing model. The trapezoidal link is made from hollow-section aluminium. This torsionally and flexurally rigid control arm absorbs a large portion of the forces acting on the wheel. Together with the track rod located behind it, it thus determines the elastokinematic behaviour of the axle. This design is notable for its low weight as well as its outstanding space efficiency. The compact design permits a low load-area floor in all versions, coupled with a generous load-area width. All wheel control elements pivot on the resiliently mounted subframe via rubbermetal mounts which isolate axle vibration very effectively from the body. Moulded rubber mountings are also used for the suspension springs between the
trapezoidal link and the body's longitudinal member. Here again, the material chosen provides excellent acoustic insulation. The twin-tube gas-filled shock absorber is connected to the wheel carrier, so that a direct-ratio effect is obtained. Combined with the separately mounted spring, this ensures a particularly sensitive response from the shock absorber. The trapezoidal links and wheel carriers on the new A4 generation now also originate from the S4, a car whose suspension has demonstrated its all-round superiority in numerous individual and comparative tests conducted by the trade press. However, several mounts and the shock absorbers, which are considerably larger than on the previous model, have been adopted again from the A6.
Thanks to the precision work that has gone into modifying the rear suspension setup, the dynamic qualities of this basic structure are demonstrated even more effectively. This all adds up to agility and excellent directional stability, outstanding straight-line running and a high level of comfort without any disturbing movements of the body. The steering: precision and lightness The new Audi A4 has hydraulically assisted rack-and-pinion steering bolted rigidly to the suspension-strut cross-member. The progress that has been made by detailed modifications can be felt above all at the steering wheel: the driver registers this as greater precision, an even more spontaneous response to steering movements and more precise feedback from the road. Audi's developers have also achieved an optimum steering layout in terms of safety for the A4. Because the steering column is mounted in two universal joints,

The system has been developed to an even higher standard in terms of both electronics and hydraulics. New pressure control ensures even more precise intervention of the ESP stability functions in accordance with the given situation, particularly when the car is understeering. In the event of excessive understeer, all four wheels are braked if necessary so that the vehicle can be returned to its original course. Yet another new feature is the brake disc wiping function integrated into ESP. This new function helps to keep the brake discs largely dry on wet roads even when the driver does not apply the brakes for a relatively long time. To provide
this effect, the brake linings are pressed against the discs under low hydraulic pressure at regular intervals, ensuring even more spontaneous brake response under wet conditions, too. This process goes unnoticed by the driver. The new Audi A4 comes for the first time with a two-stage ESP deactivation button: pressing the button briefly, the driver is able to deactivate the traction control system ASR. This is sometimes necessary in deep snow or on gravel roads in order to pull away smoothly. Pressing the button a bit longer, on the other hand, the driver is able to deactivate ESP in all operating conditions. This is necessary on the race track, for example, to enable an intentional sideways slide through the use of the brakes. Even then, however, the EDL and ABS functions remain operative. Wheels and tyres Even the four-cylinder and six-cylinder versions (above 96 kW) of the new Audi A4 come as standard with 7x16-inch alloy wheels shod with 205/60 R16 tyres. The particularly powerful six-cylinder versions and the 2.0 T FSI run on 7x16inch wheels with 215/55 tyres. As an option, the new Audi A4 is available with a choice of ten different wheels measuring up to 7.5 x 17 inches and running on tyres up to 235/45 R17. In winter, too, the A4 driver has the choice of three wheels up to 7x17 inches in size and running on 225/50 tyres.

sideguard as standard

In addition to the large-area front airbags, the occupants are protected by several side airbag systems. In the event of a side impact, remote sensors transmit signals which are compared with those from the sensor in the central airbag control unit. The risk of injury to the torso and pelvic regions of the body in a side crash is above all reduced effectively by the thorax/pelvis side airbags integrated into the front seat backs. Rear thorax/pelvis side airbags are available as an option for the outer rear seats. The head and neck regions benefit from sideguard, a unique safety extra not just in this vehicle category. This head-level side airbag system covers virtually the entire side window area, from the A-post to the C/D-post. A hybrid gas generator inflates the airbag, which then remains inflated for several seconds. This ensures that sideguards protective effect is also preserved throughout any secondary collisions, e.g. in a rollover. However, sideguard does not prevent the occupants from escaping from the car or obstruct access for rescuers. An extensive system of crash sensors ensures that the airbags are ignited at exactly the right moment. In addition to the upfront sensors, the triggering system comprises several remote satellite sensors at the sides. The front airbag on the passenger's side can be activated by key (option). This is an important function, particularly if a child is to travel on the passengers seat in a child car seat. All Audi A4 models have provisions for mounting Isofix child seats on the outer positions of the rear seat.
The equipment Premium items and more The new Audi A4 is positioned in the midsize top segment. It stands out for a range of standard equipment with quality and comfort attributes that would not be out of place in the luxury class. The scope for every owner to customise his or her own car is equally important. Personal style and the desire for a touch of individuality specifically in the car's interior are playing an increasingly important role when its configuration is defined. The new Audi A4 is an unmistakable car with a standard specification that already covers virtually every requirement. And it offers the driver a huge range of possibilities for fulfilling his or her very own idea of contemporary, stylish mobility. Appearance made to measure There is a choice of 15 body colours for the new Audi A4. The colour spectrum ranges from particularly sporty shades such as Silver, metallic to Brilliant Red, and also includes the elegant colours in the range such as Liquid Blue, metallic and Dakar Beige, metallic. The high-gloss package available optionally, with drip mouldings and window capping strips, lends the car a highly elegant note. The interior also satisfies virtually every design requirement. The materials used are without exception of the highest quality a characteristic that is conveyed not only visually, but also by their feel. Audi A4 drivers can choose between a number of material and colour combinations. The equipment concept offers supreme flexibility and individuality.

All components are colour-coordinated, with the result that every configuration creates a harmonious overall appearance.
In addition to the Mikado (basic version), Mondial and sporty Strato (for the sports seats) cloth upholstery versions, customers can opt for the sporty, elegant and extremely high-quality Volterra and Valcona leather upholstery which have already met with the enthusiastic approval of A8 and A6 drivers. Another option for customers is a combination of Alcantara and leather for the sports seats. Brushed aluminium inlays on the dashboard and doors and the door sill trims with aluminium inserts are all part of the standard specification. Aluminium Facette finish silver inlays for the centre console or, as an alternative, Walnut brown or fine-grained Birch grey or beige wood inlays are available as options. The standard equipment The perfect climate can be obtained on both sides of the vehicle thanks to the deluxe automatic air conditioning in the new Audi A4. The standard version of this system, which also includes a sun sensor, allows the temperature to be adjusted separately for the driver and front-passenger sides. This system, which is equally important to comfort and safety, is part of the standard equipment specification of all new A4 models. The newly designed four-spoke steering wheel can be adjusted both vertically and horizontally. A4 2.0 T FSI, 3.2 FSI and 3.0 TDI models are fitted with servotronic power steering where the degree of assistance provided is dependent on vehicle speed. The driver's and front passenger's seats have manual fore/aft and height adjustment. A centre armrest at the rear adds an extra touch of comfort when the centre rear seat is not occupied.
The safety equipment featured as standard in the new-generation A4 is equally impressive. In the event of a collision the car's occupants are effectively protected by the robust structure of the body with predefined deformation and a highly stable passenger cell. And in conjunction with seat belt tensioners and belt-force limiters, the full-size front airbags, front side airbags and the sideguard head airbag system offer the driver and passengers a high level of protection.
The two full-size front airbags are activated in two stages, depending on the severity of the accident. Active front head restraints fitted as standard help to protect the occupants against whiplash injuries in a collision from behind. Active safety benefits from the latest-generation electronic stabilisation program ESP 8.0 complete with hydraulic brake assist, anti-lock brake system ABS, electronic brake-force distribution EBD, the traction control system ASR and the electronic differential lock EDL. The brake-disc cleaning function is also an integral part of ESP. In wet conditions, this removes the film of water from the discs at predefined intervals, thus helping to reduce the vehicles braking distance considerably. The motorway indicator function improves safety when overtaking: if the indicator level is pushed briefly to just before its detent position and then released, the indicators flash three times. Electric front windows with anti-pinch protection and electrically adjusted door mirrors optimise operating convenience. The central locking is equipped with radio remote control, allowing the car to be locked and unlocked from quite some distance away. The car can easily be identified for example on a large, anonymous car park by unlocking it with the remote control; its indicator lights then flash making it easy to locate.

The windscreen wipers have an adjustable wipe interval, and automatically perform one more cycle after the last wash/wipe operation to make sure that any remaining splashes of water are removed. The instrument cluster's central display shows for instance the distance remaining on the fuel in the tank, the outside temperature and the distance remaining to the next service. The standard free-form headlights behind clear-glass covers guarantee good visibility. High-performance halogen fog lights integrated into the bumper are also part of the standard specification.
All Audi A4 models from 96 kW upwards are equipped with sporty 16-inch alloy wheels as a standard: the 1.6 and 1.9 TDI four-cylinder versions have 16-inch steel wheels. The optional equipment As many as ten alloy wheels of sizes 7x16 to 7.5x17, available from the launch date, give drivers a further means of enhancing the characteristic appearance of their new Audi A4. Tyre sizes up to 235/45 R17 ensure an uncompromisingly sporty character that is manifested in ways other than just visually. In addition, quattro GmbH offers four other alloy wheel versions of sizes from 7.5x17 to 8x18 inch. There are also wheel and tyre sets for winter use: for the entry-level 1.6 and 1.9 TDI models there is a 7x16-inch steel wheel with full-diameter cover. This is best used in conjunction with size 205/55 R16 winter tyres. Two cast aluminium wheels of size 7x16 and 7.5x17 inch, fitted with tyres of up to 225/45 R17, are available for all versions. The new Audi A4 provides the perfect infotainment experience.
Two different navigation systems, which both use GPS satellite navigation, help the driver find the fastest route from A to B. The basic navigation system uses spoken commands and pictograms in the central instrument cluster display to guide the driver. The corresponding controls are located in the centre console. The new Audi radio-navigation system plus with DVD drive not only enables almost limitless navigation throughout Western Europe, it can also be used to play audio and MP3 CDs. Its operating principle follows the same clear logic as the Audi MMI, familiar from the A8 and A6. The 6.5-inch colour display shows the map and the visual route description, while the driver information system translates the corresponding directions into pictograms and adds information on distances and arrival time.
The new storage medium of the DVD for the navigation system provides more than ten times the storage capacity of a conventional CD-ROM, coupled with a noticeably faster access time. Almost the entire road network of Western Europe can now be stored on a single data carrier, overcoming the inconvenience of having to change the CD when the driver crosses a national border. A further advantage is that the navigation system calculates the route much more swiftly than on CD-based systems. This is particularly noticeable during map loading and when using the zoom function. The birds eye view of the screen, which can also be split if required, facilitates visual orientation on the map. The audio systems offer the ideal combination of convenience and equipment options for every customer: chorus with cassette player, eight loudspeakers and diversity aerial for optimum reception concert additionally with CD player (instead of cassette player)

symphony with cassette player and a 6-CD changer as well as a diversity aerial
The BOSE sound system (in conjunction with the concert and symphony audio systems) additionally provides a concert hall atmosphere in the A4. Mobile phone preparations for D/E-network phones offer convenient voice control for entering and dialling up to 50 different numbers. Digital signal processing serves to compensate disturbing noise and guarantees excellent voice quality. The choice of a multifunction steering wheel ensures a particularly high degree of operating convenience. The Bluetooth interface guarantees the system's future compatibility. Communication in a broader sense likewise takes place while the car is being manoeuvred into a parking space: the acoustic parking system determines the exact distance to the next car whether to the front or the rear by means of ultrasonic signals.
Sensors integrated discreetly into the bumpers measure the distance and prompt acoustic signals which let the driver know how much clearance remains. Electric adjustment can be ordered as an option for the driver's and front passenger's seats. The seat positions can be stored by a memory function (also available as an optional extra). The position of the door mirrors can also be memorised. The storage package can accommodate numerous personal items. It includes drawers under both front seats, luggage nets on the front seat backs and two additional cup holders in the rear centre armrest. On warm days, the optional cooling box in the glove compartment is a welcome feature: the contents are cooled by the automatic air conditioning while the car is
on the move and remain at a low temperature for some time after the engine has been switched off. The utility of the rear seat can likewise be maximised: a rear bench split 1/3 to 2/3 (standard on Avant and quattro models) is available as an option. A loadthrough facility with ski bag is also available. A unique attribute for a car in the midsize class is the availability of double glazing for the Audi A4. This equipment item, which is a typical feature of luxury-class vehicles, improves the interior acoustics still further and also optimises protection against break-ins. The Audi range of special accessories also offers perfect solutions for when the sun goes down: the best examples are the xenon plus headlights with outstanding dipped and main xenon beams and automatic-dynamic headlight range control. They illuminate the area in front of the car evenly and intensively. A headlight cleaning system in addition comes to the driver's aid if there is a risk of dirt accumulating.

345 millimetre discs at the front are a visual indication of the brake systems performance. The new S4, like the other S models, can be ordered in a choice of exclusively available paint finishes: Imola Yellow, Brilliant Red, Sprint Blue, pearl effect and Deep Green, pearl effect. The S4 can also be ordered in Brilliant Black, in the metallic colours Silver or Dolphin Grey and in Phantom Black or Moro Blue, both with pearl effect. The Audi S4 is notable not only for its sporting exterior, but even more so for its inner values. This applies not only to its technology, but also to the interior. The instrument cluster, for example, has the characteristic grey S dials and special needles. The new three-spoke leather sports steering wheel with S badge also accentuates the vehicles particularly sporty character. If the customer orders a 6-speed tiptronic transmission, gears can also be changed using the shift paddles on the steering wheel. Recaro sports seats provide firm lateral support and excellent comfort on long journeys. Not only the driver and front passenger benefit from these qualities, but also passengers on the two rear seats. Engines and transmissions The heart of the new Audi S4 is again quite clearly its engine a tremendously powerful V8 with a displacement of 4.2 litres and a five-valve cylinder head. This engine is notable not only for its dominant power output (253 kW/344 bhp), but also for its unbeatably short design. The development engineers, however, have not economised when it comes to power. The V8s thrust enables the new Audi S4 with 6-speed manual gearbox to sprint from 0 to 100 km/h in only 5.6 seconds. It takes just 20.6 seconds to reach 200 km/h, whilst the top speed is a governed 250 km/h.
The new 4.2-litre engine delivers its maximum power at 7,000 rpm. The maximum torque of 410 Nm is available at 3,500 rpm. Even at just 1,100 rpm the large V8 produces almost 300 Nm, and between 3,000 and just under 4,500 rpm the peak-torque range is always above 400 Nm. Clearly more impressive than such figures is the combination in practice of the engines spontaneous response to every movement of the accelerator pedal, its astonishing free revving and hefty torque that is characteristic of a V8. And then there is the experience of an equally characteristic V8 sound reserved and practically free of vibration in the low speed band and with a sonorous tremolo under load. It certainly makes no secret of the engines potential. Thanks to efficient emissions control with primary and main catalytic converters, the new Audi S4 also remains clearly within the EU4 limits. The S4 is available with a choice of 6-speed manual gearbox or 6-speed tiptronic with dynamic shift program DSP and sport program. This automatic transmission is designed specifically to meet demanding handling requirements: weight reduction, rapid shifts and an optimised shifting strategy make sure that the convenience of the automatic transmission is combined with the sports performance specific to the S4. The chassis The dynamic chassis comprising lightweight aluminium components is based on the much-praised axle design of the A4 series and provides the ideal basis for maximum agility as well as excellent suitability for everyday use. It is not least thanks to these characteristics that the S4 has already put up an impressive performance in numerous comparison tests conducted by the trade press, clearly distancing itself from its competitors.
