The M Double Clutch Transmission (DCT) with Drivelogic is an innovative double-clutch transmission specially designed for the BMW M high-revving engines. It comes with traction-optimized automatic gear selection, Launch Control, Low Speed Assistance, as well as the Automatic Start/Stop function. It can be controlled either automatically or manually using the gearshift paddles on the M leather steering wheel or the gear selector in the centre console. The M DCT makes it possible to change gears extremely quickly without an interruption in tractive force. This is due to two subtransmissions, each with its own clutch, which continuously relay the power of the engine to the wheels by overlapping the clutches. The gear shift strategy is also optimized with the help of existing navigation data – the M DCT, for example, downshifts proactively ahead of bends. The additional Launch Control function, which allows maximum acceleration from a standing start, offers an extremely dynamic driving experience: shifting gears at high speed is possible without using the clutch, and without any interruption in the power delivery. Regardless of whether the driver selects the automatic (""D"" mode) or manual (""S"" mode) mode, Drivelogic always offers three shifting options: sporty, comfortable and efficient.
