IN DETAIL: BMW 7-SPEED M-DOUBLE CLUTCH TRANSMISSION

BMW M GmbH is proud to be the world�s first car maker now offering a seven-speed Double Clutch Gearbox specially conceived and designed for a high-speed power unit. Compared with all conventional systems available so far, this new gearbox ensures an optimum gearshift and even more dynamic acceleration, and at the same time reduces fuel consumption by a significant margin.

The new M double-clutch transmission with Drivelogic shifts gears without the slightest interruption in the flow of power, thus promoting both the sports driving experience and gearshift comfort for the driver. In its gearshift characteristics, the new M double-clutch transmission with Drivelogic is ideally matched to the fast-revving V8 power unit in the new BMW M3. Making its debut in the BMW M3 Coup� and the BMW M3 Convertible, the new transmission helps to provide even faster and more dynamic acceleration.

Given these qualities, the seven-speed Double Clutch Gearbox offers particularly the sporting and ambitious driver an attractive alternative to the six-speed manual gearbox featured as standard. Maintaining a permanent flow of power from the engine, reducing gear increments to a minimum and using dynamic torque surge when shifting gears, the M double-clutch transmission with Drivelogic ensures a truly sporting experience at all times when shifting gears, whether in the automatic or manual mode.

A further essential point is that Drivelogic exclusive to BMW M with its five shift programs in the D- and six shift programs in the S-mode gives the driver the opportunity to tailor his BMW M3 individually to his personal style of motoring.

An even faster and more comfortable gearshift is ensured by the M double-clutch transmission with Drivelogic both in the automated (D-) mode and when driving in the manual (S-) mode.

The process of shifting gears is basically the same as on BMW�s proven Sequential M Gearbox, meaning that even when shifting gears manually there is no need for a clutch peddle and the driver may keep the accelerator fully depressed during the shift process.

To activate the D- or S-mode and to shift to reverse, the driver first has the choice of the new sports shift lever exclusive to the BMW M3, enabling him to shift gears himself in the S-mode. In this case he moves the gearshift lever only along one line, in a sequential process.Read All Article
