Aside from the S54 engine, how is the drivetrain of the revised M coupe altered?
The other major addition to the revised M coupe is an M-tuned version of Dynamic Stability Control (DSC) for all markets. An evolution of Automatic Stability Control plus Traction (ASC+T), DSC compensates for oversteer and understeer through manipulation of each individual brake as determined by sensors measuring steering angle, vehicle speed, cornering force, brake pressure and the vehicle’s rotation around its vertical axis. The system is fully integrated with the BMW/Siemens MSS 54 engine management control, and its intervention can be reduced or completely eliminated via a console-mounted button.
