New BMW M DKG Transmission

7-speed double-clutch with DriveLogic

The new BMW M3 Coupe, Sedan and Convertible will be the first to feature BMW's latest technological achievement. The M DKG is a seven-speed double clutch transmission with BMW M's DriveLogic.

The new transmission is capable of even faster gearshifts which result in faster acceleration than the six-speed manual of the new M3, improved fuel economy and reduced emissions. The M3 coupe is capable of a 0 - 100 km/h time of just 4.6 seconds (0.2 seconds faster than the manual) while still using only 11.9 liters of fuel per 100 km.

The transmission comes with an wide array of program choices, 11 to be precise. Five shift programmes in fully automatic mode, six in manual mode which are supplemened by the Launch Control program which will provide maximum use of every last horsepower from the 4.0 liter V8 (309 kW / 420 hp). We will have to wait and see whether this Launch Control is as capable as BMW claims.

As the name says, the M DKG uses two clutches, both are oil-cooled, one is used for the uneven gears and reverse while the other is used for the even gears. One clutch is of course in use while driving, while the other is already pre-engaged. This is the big secret behind the double-clutch system, resulting in almost instantaneous gearshifts.

BMW's Drivelogic system is capable of several different shifting options, ranging from F1 style as-fast-as-possible gearshifts to luxurious and smooth gearshifts for boulevard cruising. The transmission can be used through either a sports selector lever in the center console or aluminium paddle-shifters on the steering wheel.

New BMW M3 owners will be happy to hear that the M DKG transmission is capable of taking some punishment on the racetrack.
