Underbody

The almost fully closed vehicle underbody plays an important role in the aerodynamics. The acoustics in the vehicle are also significantly improved as a result. In the front section, the air flow is directed past the front wheels by the displacers (7). In this way, the airflow on the front wheel is reduced. In the rear area, the 2 wind deflectors (3) on the axle and the cover of the rear axle differential (5) contribute to optimized underbody flow together with the rear diffuser (4), which is adapted for each drivetrain design.

     24 V Electronic Power Steering

    The greater weight of the engines in the G30 on vehicles with 8-cylinder engines results in a higher front axle load. This has the effect that the required power of the steering assist increases. Due to these high currents, it is necessary to increase the voltage supply of the EPS to 24 V.

     xDrive

    Concept xDrive is the all-wheel-drive system of the vehicle. The interaction of xDrive and DSC Dynamic Stability Control further optimizes traction and driving dynamics. xDrive variably distributes the driving forces to the front and rear axles as demanded by the driving situation and road surface
