By accessing the MDrive menu in the iDrive system, M6 owners can choose personal preferences for SMG Drivelogic shift programming, DSC modes and deactivation status, and EDC and steering settings. MDrive also controls the content displayed in the available Head-Up Display, and activates the M Multi-function sport seats’ Active Seat Backrest feature, which selectively inflates the bolsters during hard cornering to keep the driver and front passenger in place. The most important MDrive feature, however, controls the level of engine power and throttle response. The default setting is P400, which directs the M6 to generate 400 horsepower. Select P500 from the menu, and the M6 generates 500 horsepower while quickening the throttle response. Select P500 Sport from the menu, and throttle response goes from instantaneous to damn near retroactive. Once all of these MDrive selections have been made and saved, the tailored combination is immediately accessible through the magical little “M” button on the steering wheel. Push that, engage Launch Control, and that silly little boy in Daddy’s Corvette C6 won’t be able to read your blur of a license plate, much less hope to catch you – unless he’s really, really good with a clutch.
