Enhanced dynamics, greater efficiency: new six-speed manual gearbox and optional seven-speed Double-Clutch Gearbox.

Both the BMW 135i Coupe and the BMW 135i Convertible come as standard with a newly developed six-speed manual gearbox. Optimised for maximum efficiency, this high-tech gearbox features dry sump lubrication significantly reducing drag forces and completely avoiding splash losses in the interest of even greater efficiency all round.

The seven-speed double-clutch gearbox with Sport Automatic featured for the first time in the BMW 1 Series makes an even greater contribution to the optimisation of driving characteristics in the spirit of BMW EfficientDynamics. The double-clutch gearbox improves both acceleration and the efficiency of these compact top-flight performers, at the same time combining this dual progress with the comfort features of a BMW automatic transmission. (posted on conceptcarz.com) The seven-speed double-clutch gearbox shifts gears without the slightest interruption of power and torque and offers the driver the choice of either automatic transmission or a manual gearshift.

The fast and smooth shift of gears allows unusually harmonious acceleration and helps to reduce both fuel consumption and emissions. The close, sporting increments of the seven gears ensure that the optimum transmission ratio is always available in all situations.

A combination of dry sump and injection lubrication serves to further optimise the efficiency of the engine through a supreme level of oil supply.

Last but not least, the double-clutch gearbox is controlled with utmost convenience either through the newly designed gear selector lever or by gearshift paddles on the §teering wheel.
