Porsche has announced all of the juicy details related to the PDK transmission now on offer for the 718 Cayman GT4, 718 Boxster Spyder, and 718 Boxster/Cayman GTS 4.0 models.
All of these models have previously been sold exclusively with six-speed manual transmissions but with the optional seven-speed dual-clutch, Porsche hasn’t just improved the performance of the models but will also generate additional sales.
Porsche says that the 718 Cayman GT4 and Boxster Spyder models can sprint to 60 mph (96 km/h) in a mere 3.7 seconds with the PDK. That’s significantly quicker than models with the standard stick shift that require 4.2 seconds to reach the same mark. As for the Boxster and Cayman GTS 4.0 models, they can hit 60 mph in 3.8 seconds with the PDK down from 4.3 seconds with the manual.
The German automaker’s PDK available for these 4.0-liter models has a shorter seventh gear ratio than the PDK available on other 718 models. Additionally, PDK-equipped variants benefit from an extra 8 lb-ft (10.8 Nm) of torque. The PDK also improves handling as Porsche has coupled it with a new limited-slip differential operating with higher locking values that reportedly results in 30 per cent more grip in traction mode and 37 per cent more grip in over-run mode. With improved acceleration and even better handling, there’s no doubt the PDK models will also be faster around a racetrack.
Buying a PDK-equipped model comes at a bit of a premium. For Boxster and Cayman GTS 4.0 models, it adds $3,730 to the sticker price. For 718 Boxster Spyder and Cayman GT4 models, the price hike amounts to $3,210.
