2013 Audi A4 / S4 — Owner's Manual
Engine and automatic transmission. Depending on the mode, the engine and the automatic transmission respond quicker or in a more balanced manner to an accelerator pedal movements. In the sporty-dynamic mode, the automatic transmission shifts at higher RPMs. The steering adapts in terms of steering effort and steering ratios.
Indirect steering that moves easily, like the steering in comfort mode, is best suited to long drives on a highway. In contrast, dynamic mode provides sporty, direct steering. The follow ing applies to vehicles with dynamic steering*: the steering ratio changes based on vehicle speed in order to maintain optimum steering effort for the driver at all times. This sets the steering to be less sensitive at higher speeds in order to provide improved vehicle control.
At reduced speeds, however, steering is more direct in order to keep the steering effort as minimal as possible when the driver is maneuvering the vehicle. At low and average speeds, dynamic steering additionally provides more responsive steering performance. The adaptive dampers* use sensors to record information regarding steering movements, braking and acceleration operations by the driver, road surface, driving speed, and load. This makes it possible to adapt damping to the driving situation virtually in real time.
Drive select also makes it possible to satisfy the desire for sporty suspension (Dynamic) and comfortable suspension (Comfort) without giving up balanced tuning (Auto).
