Introduction: The primary 2011 Audi A8 development objective for its running gear and suspension systems was to enhance the already exceptional driving dynamics and comfort of previous Audi A8 models. For example, the fi ve-link front axle, trapezoidal
link rear axle, as well as the Adaptive Air Suspension, have been further refined.
A new high speed FlexRay bus system quickly provides vehicle dynamic information to relevant systems. A new central sensor control module reduces the number of sensors in the vehicle. As with its predecessor, the Adaptive Air Suspension system (PR Number 1BK) is standard equipment on the 2011 Audi A8.
An adaptive sport running gear and suspension (PR Number 2MA) is optional. When compared to the standard 1BK suspension, the optional adaptive sport running gear lowers the ride position of the vehicle by approximately 0.40 in (10 mm).
