The M double-clutch transmission with Drivelogic is an innovative 7-speed double-clutch transmission specially designed for the BMW M high-rev engine. The system boasts a traction-optimised automatic gear selection, Launch Control, Low Speed Assistant, as well as an Automatic Start/Stop function. It makes it possible to change gears extremely quickly without any loss in power. Two sub-transmissions, each with its own clutch, continuously relay the power of the engine to the rear wheels. Gear changes can be controlled automatically or manually using the gearshift paddles on the steering wheel, or the gear lever. Drivelogic can be automatically (D Drive mode) or manually (S sequential mode) controlled, and in each mode three shifting options are available: extremely sporty, comfortable or efficient. Just as with Launch Control, which allows maximum acceleration from a standing start, an extremely dynamic driving experience is the result: shifting gears at high speed is possible without using the clutch and without any interruption in the power delivery. The transmission management and integrated Launch Control are matched to the higher power output and increased torque of the M4 GTS.
