The main objective in the development of the running gear and suspension systems for the new Audi A8 ’10 was to further improve the already exceptionally high standards of the predecessor in terms of driving dynamics and comfort. For this purpose, tried and tested systems such as five-link front axle, trapezoidal link rear axle as well as adaptive air suspension have been consistently further developed and fitted in the new luxury class model.

The system networking level has been substantially increased. With the powerful FlexRay bus system it is possible to use a central sensor unit that makes available vehicle movement information to the relevant systems such as ESP, adaptive air suspension,
dynamic steering and the sport differential. With this unit it has been possible to significantly reduce the number of sensors in the vehicle.

In the same way as in the predecessor model, the new Audi A8 ’10 is available exclusively with adaptive air suspension.

The following running gear and suspension variants are available for the Audi A8 ’10: The standard running gear and suspension (adaptive air suspension) with the production control number 1BK is the standard production version. The sport running gear and suspension 2MA (adaptive air suspension sport) is the option for customers with sporting ambitions. Compared to the standard running gear and suspension 1BK, the trim position of vehicles equipped with a sport running gear and suspension is reduced by 10 mm. The poor road running gear and suspension 1BY is offered instead of the standard version for use in corresponding markets.

In this case, the trim position is 8 mm higher than the standard running gear and suspension 1BK. Vehicles with poor road running gear and suspension are additionally equipped with a reinforced powerplant guard on the front axle.
