Automatic or sequential – it’s the driver’s choice. The M double-clutch transmission with Drivelogic allows both automated and manual selection of gears. In both cases gears are shifted at a rate and with a level of precision never seen before on a conventional manual gearbox or automatic transmission. At the same time the driver is able to enjoy the optimised gearshift comfort of the M double-clutch transmission while switching over whenever he wishes to a more active and dynamic style of motoring.

To change from the automated to the manual gearshift mode, the driver is not even required to move the gearshift lever in the appropriate direction. Rather, all he has to do while driving is to operate one of the gearshift paddles on the steering wheel to shift gears immediately and change over to the S-mode. Then, via the appropriate paddle or with the help of the gearshift lever, the driver subsequently selects the gear of his choice.

The electronic control unit relieves the driver of the usual chore of shifting down in a predetermined process independently of the gearshift mode selected – for example when rolling towards traffic lights switching to red. And in all operating modes and driving programs, a gear indicator in the instrument panel informs the driver of the gear currently selected by the automatic mode or by the driver himself.

M-specific Drivelogic with eleven driving programs. The driver of a BMW M3 equipped with the M double-clutch transmission has the choice not only of automated and manual selection of gears, but also variable gearshift characteristics both in the D- and S-mode. For in both cases he is able to determine the degree of gearshift dynamics as he wishes. The configurations available range in several steps from a more balanced, comfort-oriented all the way to a very dynamic, racing-like set-up of the transmission.

To provide this additional function, Drivelogic specially tailored to the M double-clutch transmission provides no less than five driving programs in the D- and six programs in the S-mode.

This gives the driver the opportunity to configure his BMW M3 perfectly to his personal preferences also when it comes to the car’s gearshift characteristics. At the same time he has the freedom to choose the appropriate set-up in various driving situations, taking, say, weather conditions, his route, or the load/number of passengers the car is carrying into account.
