Porsche Doppelkupplung (PDK)
Porsche Doppelkupplung (PDK) is an automated double clutch transmission similar to VW/Audi DSG or BMW SMG.
The optimised 7-speed PDK, featuring both a manual and an automatic mode, is available as an option and offers extremely fast gear changes with no interruption in the flow of power. And that's with even faster acceleration performance and a further reduction in fuel consumption.
A first for the 911 models: in manual mode, the shift direction simulates that of racing cars and the 911 GT3 models - to the rear to shift up, forwards to shift down. For a racetrack driving experience wherever you are.
Gears one to six have a sports ratio, with top speed being reached in sixth gear. Seventh gear is ratioed primarily for fuel economy.
PDK is essentially two gearboxes in one. This double-clutch arrangement provides an alternating, non-positive connection between the two half gearboxes and the engine by means of two separate input shafts. The flow of power from the engine is transmitted through one half gearbox and one clutch at a time, while the next gear is preselected in the second half gearbox. During a gear change, therefore, one clutch simply opens and the other closes at the same time, enabling gear changes to take place within milliseconds.
