The M6 Coupe sports a carbon fiber roof panel, which lessens the overall weight and also lowers the center of gravity. These roof panels are becoming an M signature, as they are also used on the new BMW M3.
Two buttons on the right spoke of the steering wheel, the M and the star, are programmable within certain limitations. You can set driving characteristics with the M button, and program cabin tech shortcuts for the star button.
The redline on the tach actually moves, starting low when the car is cold and eventually running up to this level. There is a preliminary yellow zone running into the 7,000 range, while the redline hits at above 8,000 rpm.
The EDC button controls the three stages of the Electronic Damping Control. No lights mean comfort, one light is normal, and both lights come on when the system is in full sport mode. In normal mode, EDC is dynamic, adjusting to the driving style.
The iDrive controller is present, serving as the main means for using the software interface that controls navigation, stereo, climate, and the phone system. It is augmented by a few dashboard controls and voice command.
