Adaptive M suspension.

High dynamics, exceptional roadholding, improved comfort on long journeys: The Adaptive M suspension automatically adapts to road conditions and driving style. The set-up, which ranges from sporty to comfortable, can be changed via the Driving Experience Control.

Variable sport steering.

The variable sport steering with Servotronic conveys a direct contact with the road. It reacts to the angle of the steering wheel with varying steering ratios. This improves handling when driving more dynamically and reduces the effort needed to steer when parking and turning.

M sport differential.

The M sport differential optimises traction and driving stability when changing lanes or accelerating out of a bend, when taking bends at high speeds or on different road surfaces. Traction is optimised with the help of an electronically operated device that reduces the difference in revolution speed between the rear wheels.

8-speed Steptronic Sport transmission.

The 8-speed Steptronic Sport transmission offers incredibly sporty gear changes. Whether automatic or manual using the selector lever or gearshift paddles – for comfortable coasting or incredibly dynamic driving.

M Sport brake.

The M Sport brake has four-piston fixed calipers at the front and single-piston floating calipers at the rear in Red high-gloss with the M logo and features large brake discs to ensure an outstanding braking performance. Adapted to the very high dynamic potential of the vehicle, it ensures excellent braking even with a decidedly sporty driving style and in wet conditions.
