Short version
Sporty and superlative, progressive and emotive – the A4 takes Audi into a new dimension in the midsize car segment. The saloon’s engines – three TDI units and two petrol engines that also have direct fuel injection – provide supreme performance with fuel consumption that is an average of nine percent lower than the previous model. The highly efficient powertrains are just as clear evidence of Audi’s outstanding technical expertise as the dynamic suspension or the many other technologies adopted directly from the large luxury class. The Audi A4 reaches the market at the end of November 2007, at list prices in the region of 26,000 euros. The new Audi A4 – the new way to drive.
New design idiom
The new Audi A4 combines many fascinating aspects. Its design is expressive, taut and dynamic. The high precision and technical character of its styling clearly confirm Audi’s leading position in this field. Compared with the previous model, the designers have altered the proportions to create a new, sporty impression. The front overhang is shorter, the bonnet and wheelbase distinctly longer.
At an overall length of 4.70 metres, the new A4 is a large saloon. It boasts a substantial, powerful road presence. Its body illustrates the technical progress that has been made: it is significantly more rigid and safer than the previous model, but also distinctly lighter, thanks to intelligent weight-saving. With a drag coefficient of cD = 0.27, the new saloon cuts its way through the wind with ease, and its 480-litre boot is larger than that of any of its direct competitors.
Inside the new A4, the ambience is spacious and full of light, as would be expected in a much larger model. It embodies the traditional Audi strengths: a distinguished appearance, no-compromise high-quality workmanship with close attention to detail and logical, intuitive controls.
A whole series of high-tech optional extras taken from the luxury class is available to enhance the interior still further, from the MMI operating system, acknowledged as being superior to its competitors, to the automatic air conditioning with three-zone control. To take one’s seat in the new A4 is to experience the sensation typical of an Audi – one immediately feels at home. In the safety area too, the brand sets new standards: the airbags and seat belt force limiters work together even more effectively to protect the occupants better than ever before.
The new Audi A4 is being launched with a choice of five refined, powerful engines, covering a power-output range from 105 kW (143 bhp) to 195 kW (265 bhp). All of them use the direct fuel injection principle: FSI technology for the two petrol engines and the common-rail system for the three TDI units. The four-cylinder engines are turbocharged. With their smooth running and impressive flow of power, the engines in the new A4 are a source of pure driving pleasure. They also use distinctly less fuel than the corresponding units in the previous model: consumption is down by an average of 13 percent for the petrol engines and six percent for the TDI units.
More dynamic than ever: the quattro driveline
In the transmission area, Audi offers customers a wide range of high-tech solutions. Easily operated manual gearboxes or tiptronic automatic transmissions, and also the multitronic continuously variable transmission, deliver engine torque to either the front wheels or the quattro permanent four-wheel-drive system. For the new saloon model, this is more dynamic than ever before, with the torque split biased more strongly to the rear wheels.
The driver will experience the new A4 as the sportiest of the midsize saloons – a car that is agile, precise and effortless to control. The differential has been moved further forward in the driveline by interchanging its position with the clutch or torque converter. This has enabled the front axle to be repositioned 154 millimetres further forward – a solution that permits the axle loads to be ideally balanced. For the new Audi A4, the dynamic suspension is a totally new development. Thanks to the use of numerous aluminium components, the suspension, steering, wheels and brakes are exceptionally light in weight.
Two innovative technologies add even greater fascination to the driving experience. One of them is the Audi drive select control system, with which the driver can adjust the operating characteristics of the engine, automatic transmission, steering and adaptive damping to suit his or her own preferences. The other is Audi dynamic steering, which operates with a superimposed gear system that varies the effective steering ratio according to road speed. Close to the handling limits, it acts together with the ESP to stabilise the car by slight but very rapid adjustments to the steering. In this way, the system combines sporty driving fun with a high level of safety.
The innovative assistance systems on the new A4 make driving even more relaxed and enhance the driver’s control of the situation. Audi equips its new saloon model on request with various high-tech systems that have so far been available only on luxury cars. These systems control the distance from the car in front, help the driver to keep within the chosen lane or to move safely from one lane to the next, and provide support when parking the car.
Technical area of the future: multimedia
The Audi A4 also sets new standards for a midsize car in one of the most fascinating technical areas of the future, namely multimedia. The new saloon enters production with a series of communication and entertainment technologies at the customer’s disposal that would be impressive even in a luxury-class car.
Among the components are various audio systems, a TV receiver, two navigation systems, an iPod interface and a highly convenient Bluetooth telephone. Audi is supplying the new A4 in three equipment lines, known as Attraction, Ambition and Ambiente.
