Sequential gearshift like in a racing car. The seven-stage M double-clutch transmission with Drivelogic is operated by an M-specific sports gearshift lever transmitting the driver’s shift commands electronically to the transmission management. This serves to facilitate the gearshift process, reducing control forces in accordance with the dynamic character of the gearbox and the car itself. The shift commands determined by the driver through manual control are generated in a sequential process, that is on one single level.

To shift up to the next gear, all the driver has to do is briefly tip the gearshift lever backwards, to shift down all he does is briefly tip the lever forwards. In both cases the lever automatically moves back to its starting point after operation.

This configuration is the same as on the sequential gearboxes used in motor- sport and is the logical control mode for the sports-minded driver. At the same time this highlights the close connection between the M double-clutch transmission and motorsport technology.

Gearshift paddles on the steering wheel to shift gears quickly and smoothly. In addition to the newly developed gearshift lever, the BMW M3 equipped with an M double-clutch transmission also comes with gearshift paddles on the steering wheel. Made of solid aluminium, these paddles enable the driver to shift gears manually ultra-fast and with maximum safety. In particular, this is because he does not have to take his hands off the steering wheel when shifting gears, which means extra safety in controlling the car.

Fitted firmly to the steering wheel, the gearshift paddles are always in a convenient position for shifting gears virtually level with the driver’s hands. They therefore enhance not only the driving experience, but also the high standard of safety the driver enjoys at the wheel.

Like the sports gearshift lever, the gearshift paddles operate according to the usual pattern in motorsport: The paddle on the right is for shifting up, the paddle on the left for shifting down. And at the same time the high-quality finish of the aluminium paddles also establishes a direct link to motorsport with the flair of a genuine racing car.

The kick-down function is a special feature in controlling the car, operated either by the gearshift paddles or by the gearshift lever in the S-mode. As soon as the driver presses the gas pedal right down to the floor (kick-down) and then pulls the left-hand paddle once or tips the gearshift lever forward, the transmission shifts back for optimum torque and pulling force.
