Added support.

The variable M differential lock on the
BMW M6 Convertible.

High driving stability and optimum traction, above all when pulling out of curves - the variable M differential lock takes care of that. Using this function effectively prevents spinning of the drive wheels. Even when wheel grip varies enormously, such as on snow, gravel or ice, the M differential lock supplies that decisive extra portion of pulling power. Sporty drivers appreciate the system because it optimises handling while at the same time supporting the thrust from the rear-wheel drive.
