2012 All-New Porsche Carrera: The 7-Speed Manual (Part 3/12)

PORSCHE Europe: Official Press Release

The new Porsche 911 Carrera

The World’s First Seven-Speed Manual Transmission for a Passenger Car

Experience with the PDK conclusively proves that a 911 Carrera can be driven very sportily with a seven speed transmission – and very economically into the bargain. That is why for the new Carrera generation, Porsche has twinned the world’s first seven-speed manual transmission for a passenger car with the PDK as standard.

It combines comfort over long distances and fuel consumption benefits without sacrificing performance. Gears one to six are sport tuned, top speed being reached in sixth gear. The seventh gear has a high overdrive gear ratio, which makes for superior comfort over long distances at lower revs combined with lower fuel consumption.

The new seven-speed manual transmission is based on the module of the familiar Porsche Doppelkupplungsgetriebe (PDK). The ratios of the third and seventh gears were modified with an eye to the manual gear changes. The third gear has a higher ratio. This reduces fuel consumption. The seventh gear has a lower ratio to maintain pulling power even at comparatively low speeds. A sequential shift lock is used to make it impossible to select the wrong gear. That means that it is only possible to change into seventh gear if fifth or sixth gear was selected beforehand. A display lights up in the rev counter showing the driver which gear is selected and an upshift indicator in the instrument cluster helps him to adopt an economical driving style.
