HOW DOES THE PORSCHE PDK TRANSMISSION WORK?

December 19th, 2019 by

Porsche lovers may be conflicted at times when trying to choose between a manual or PDK automatic transmission for the 911, Macan, Panamera, 718 Boxster, or the 718 Cayman. This could partly be due to some misunderstanding about how the PDK transmission works. So here’s a summary of its operation to help clarify it.

Porsche PDK Transmission

The first automatic transmission issued by Porsche was the Sportomatic in 1967, followed by the PDK in 1980. First used in racing versions, the PDK was used in all 956 Group C racers by 1983. It wasn’t until 2008 that Porsche began offering the PDK for its retail market vehicles. The term “PDK” translates from the German as Porsche dual-clutch transmission to clarify the terminology.

The PDK is essentially a two-gearbox system. It uses hydraulically actuated wet clutches to alternate gear selections to two driveshafts. As one clutch opens the other simultaneously closes, thereby delivering virtually unnoticeable gear changes. The wet clutch system is very resistant to overheating. Depending on the model, the PDK may offer seven or eight gears, with the top gears optimized for fuel-efficiency.

Is the PDK transmission better than the manual gearbox? That is an individual decision of each owner, but sales data show that 75% of Porsche 718 and 911 models are ordered with the PDK transmission. It offers faster acceleration and very fast shift times which might be expected since the PDK was, after all, designed first for racing.

No matter which Porsche transmission suits you, the place to get it is Manhattan Motorcars in NYC. For more information on our Porsche line or any of our fine luxury vehicles, please call 866-325-1538.
