Audi S8 – Predictive active suspension
Vehicle dynamics: active suspension, dynamic all-wheel steering, and quattro with sport differential The unique combination of innovative suspension components enables the flagship to cover the entire range from the velvety cruising of a luxury sedan to the dynamically taut handing of a sports car. The new S8 comes standard with the predictive active suspension.
The high-tech system, which works in combination with the air suspension, can lift or push down each wheel separately via electromechanical actuators. It is therefore possible for the first time to actively control the trim of the body in any driving situation and thus greatly reduce pitch or roll during acceleration or braking. The front camera, which detects larger road surface irregularities, enables this to be done predictively. The new Audi S8 can be a highly comfortable luxury sedan or a truly dynamic sports car – it’s entirely up to the driver. The Audi drive select system offers five profiles from which to choose. “Comfort +” mode is a new profile. It makes even cornering a comfortable experience: The body leans into curves by as much as 3 degrees to reduce the lateral acceleration acting on the occupants. In “dynamic” mode, the S8 turns in precisely. The maximum roll angle during fast cornering is just roughly 2.5 degrees. With the standard suspension, it is around 5 degrees. The situational distribution of roll moments enables self-steering that is neutral or minimally oversteering. The position of the S8’s body can be altered even when it is stationary. It is quickly raised by as much as 50 mm (2.0 in) when the door handle is actuated, making getting into the car even easier and more comfortable.
