S4 Audi 2009

All these measures lend the Audi S4 and the S4 Avant the driving movement of a sports car - their responses are plane, nearly reflex-like; manipulation exactness knows no cooperation. The steering guidance the driver with the road to supply the reactive, well-differentiated pointer.

Audi's drive chooses with the sport different can be merged with electronic damping control. The gas-filled hydraulic shock absorbers have an extra valve with an endless opening action. The control unit calculates the desirable damping force at a cycle frequency of 1,000 per second.

The sport differential is even capable of completely eliminating the classic loadreversal reactions when the accelerator is lifted or the brakes applied suddenly while cornering; the driver can specify this function by selecting 'comfort' mode. If the accelerator pedal is released, torque distribution between the wheels is adjusted almost instantaneously.

It takes just two figures to comprehend the dynamic potential of the new Audi S4 and S4 Avant: 5.1 seconds for the sprint from zero to 100 km/h (62.14 mph) and only 4.4 seconds for the intermediate sprint from 80 to 120 km/h (49.71 - 74.56 mph) in fourth gear. Behind these figures there is a fascinating driving experience, marked by the sonorous sound of the new mechanically supercharged V6 engine, its mighty propulsive power, its free-revving character and its sharp, spontaneous response to the throttle.
