The 7-Speed Double Clutch Transmission (DCT).

Increase driving pleasure in your BMW 135i Cabriolet with the optional 7-Speed Double Clutch Transmission (DCT). This transmission changes gears with lightning speed and without any power gap. The DCT switches between the two separate drivetrains, one for the even gears and one for the odd gears. This means that if you accelerate in third gear for example, the fourth gear is already engaged. This produces extremely fast shift times with the resulting acceleration figures approaching sports car level.
