7-Speed Dual Clutch manual transmission by ZF makes world premier in Porsche

Porsche 911 Carrera to get first ZF 7-speed manual transmission in the world

Making its world premiere in the Porsche 911 Carrera/Carrera S, lucky owners will get to experience the first 7-speed manual transmission using dual clutch technology by ZF.

The seventh generation of the Porsche 911 Carrera/Carrera S was completely new in its development, and presented at last year's Frankfurt Motor Show. The road to success has already been paved with its new opposed cylinder engine at the rear; and now ZF's 7-speed manual transmission (7MT) will contribute even further to this success.

Thanks to ZF Friedrichshafen AG this new manual transmission with 7 gears is the first of its kind to be available for passenger cars; and the benefits are based on technology and robust design. According to the ZF news release, while the technology achievement spells fuel economy for the Porsche, it is the dual clutch design that is responsible for the new, fast gear shifting characteristics of the 911.

For those unfamiliar with dual clutch designs, be apprised the dual clutch system consists literally of two separate clutches. This allow two gears to be engaged at the same time. One of the gears is transferring torque, while the next is already pre-selected. The entire shifting process takes only a few tenths of a second, without any interruption of torque. A specially developed electronic control unit regulates the dual clutch transmission and the transmission actuation. It monitors all relevant parameters such as speed, rpm and transmission ratios, and adjusts shifting depending on the driving situation.

According to ZF, their dual clutch systems combine the comfort of an automatic transmission with the sporty handling of a manual transmission. The result is a faster, smoother acceleration and superb shifting dynamics.
