Porsche Doppelkupplung (PDK) 911 GT3

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.

And yet our engineers still were not satisfied – at least, not with the development of the new 911 GT3. So they pushed the limits once again. Their goal was to produce a transmission with gear ratios specific to the 911 GT3 and with a 50% reduction in shift throw on the even crisper and more dynamic gearshift paddles. The result was a PDK perfectly tuned to match the 3.8-liter engine. This is the first time that it has been fitted in a 911 GT3, and it comes as standard.

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.

This is how it works. PDK is essentially two gearboxes in one and thus requires two clutches. 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. 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. Highly responsive and especially sporty – just as you would expect of the 911 GT3.

That in itself has consequences, not least for acceleration, for overall performance and for fuel economy. Positive consequences in fact. Driving feels even more dynamic and agility is increased.

What about the gear changes themselves? You’ll feel them and you’ll hear them. Just like before, or indeed more than ever. 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.
