The all-new active suspension on the Audi A8 is a fully active, electromechanical suspension system, which drives each wheel individually and adapts to the prevailing road conditions.

Each wheel has an electric motor which is powered by the 48-volt main electrical system. Additional components include gears, a rotary tube together with internal titanium torsion bar and a lever which exerts up to 1,100 Nm (811.3 lb-ft) on the suspension via a coupling rod.read more: audi
The active suspension specifically influences and minimizes rolling movements when cornering, and pitching movements when braking or accelerating, for instance. The customer can drive dynamically while keeping the vehicle under control or work undisturbed in the rear.
The new Audi A8 takes passive safety to a new level. The system uses the sensors networked in the central driver assistance controller (zFAS) to detect risks of a collision around the car. In the event of an imminent side impact at more than 25 km/h (15.5 mph) the suspension actuators raise the body on the exposed side by up to 80 millimeters (3.1 in) within half a second.
