When compared with the previous model, the A4 has new, sporty proportions. The front body overhang has been drastically shortened; the bonnet and wheelbase are both longer than before. In the driveline, the differential has changed places with the clutch (or torque converter), making it possible to move the front axle forward by 154 millimeters. This innovative solution ensures ideal axle-load distribution. The new A4 is the sportiest saloon in the midsize car category: agile, light and precise to control. Its dynamic suspension is a totally new design, with most of its components made from weight-saving aluminum.
The results are impressive: supremely dynamic road behavior and effortlessly precise handling.
New high-tech options make the A4 driving experience even more fascinating: Audi drive select varies the engine, automatic transmission, steering and suspension damping characteristics to suit the driver's preferences at any given moment. Audi dynamic steering varies its ratio according to the car's speed and keeps the new A4 stable close to the handling limits by slight, almost instantaneous changes to the steering angle. The damping control system for the hydraulic shock absorbers varies the damping characteristic individually, to combine sporty driving enjoyment with maximum road safety.
The new Audi A4 is being introduced with a choice of five engines, their power outputs ranging from 143 bhp to 265 bhp. The four-cylinder petrol engine, like the diesels, is turbocharged, and both types of engine have direct fuel injection. All the engines, with their supremely refined flow of power, make the A4 a pleasure to drive and, thanks to their high efficiency, consume distinctly less fuel than the previous versions.
Various transmissions are available: a six-speed manual gearbox, the tiptronic automatic transmission, the multitronic continuously variable transmission, and either front-wheel drive or quattro permanent all-wheel drive, which has been subjected to intensive development work that has made its performance even more dynamic.
