It is offered with two transmission choices: a 6-speed manual gearbox for an analog driving experience, and a 7-speed automatic gearbox with Drivelogic technology, enabling adjustable gear changes according to the driver's preferences.

How does a BMW M6 gearbox work? 

Technically, a gearbox modifies the transmission ratio between the engine and the wheels, enabling the vehicle to accelerate, slow down and maintain a constant speed. Gearboxes operate through theuse of pinions and gears, which interact to modify the gear ratio. Manual transmissions require direct intervention by the driver to change gear using a gearshift, while automatic transmissions make these changes automatically using a hydraulic or electronic system. 

In the case of the BMW M6, the automatic transmission is often equipped with advanced technologies such as Drivelogic, which enable rapid and precise gear changes according to the driver's preferences. In addition, some versions of the M6 offer specific driving modes, influencing the behavior of the gearbox for a personalized driving experience.
