BMW has also a double-clutch transmission

Although installed in a car which merits no mention here (the last iteration of the M3, with a V8 engine by the way), BMW has used a new double-clutch transmission with seven forward gears. As with other double-clutch transmissions, one of the clutches drives the odd gears (Rear, 1, 3, 5, 7), while the second manages even ones (2, 4, 6). Both clutches, in pure racing fashion, are oil-cooled with a specific dedicated oil radiator.

Then the gearbox gets some additional software and hardware called Drivelogic, which allows the driver to use up to eleven driving program choices, including a manual mode.

With all this, BMW claims that not only the car performance gets noticeably improved, but also fuel consumption and CO₂ emissions.
