Porsche Doppelkupplung (PDK)

There was a secret behind the victories in Le Mans in 1986 and 1987 with a Porsche 962C: the double-clutch transmission that Porsche had been continually refining since the 1960s. In the Porsche 962C, it already enabled extremely fast gear changes. Today, Porsche Doppelkupplung (PDK) is setting standards on the road, with gear changes that take place in milliseconds and with no perceptable interruption in the flow of power to provide faster acceleration and low fuel consumption.

The PDK has been specially adapted for the new 911 GT3. It features a transmission with gear ratios specific to the 911 GT3 and a 50% reduction in shift throw on the even crisper and more dynamic gearshift paddles. Perfectly adapted to the 3.8-liter engine. This comes as standard in the new 911 GT3. Goal achieved. Racing feel included, with seven performance-oriented gears where even 7th gear has a sport ratio engineered for maximum speed. Manual operation of the 911 GT3-specific gear selector is based on the established motorsport principle: back to shift up, forward to shift down.
The electronic gearbox control logic of the Intelligent Shift Program (ISP) offers more immediate and faster traction-induced upshifts and throttle-blip downshifts on overrun.
