Dual-clutch transmission now available for flagship Porsche 718 models

Both the Boxster and Cayman 718 GTS 4.0 variants as well as the range-topping 718 Spyder and 718 Cayman GT4 models are now available with the seven-speed Porsche dual-clutch transmission (PDK).

Compared with the 718 models with the manual transmission, the 414bhp GT models - the 718 Spyder and 718 Cayman GT4 ­- now accelerate from zero to 100km/h half a second faster, in 3.9 seconds. They reach the 200km/h mark in 13.4 seconds (0.4 seconds faster).

The 718 Cayman GTS 4.0 and 718 Boxster GTS 4.0, both with 394bhp, also improve in the standard sprint from zero to 100km/h by half a second to 4.0 seconds, and then reach the 200km/h mark in 13.7 seconds (0.4 seconds faster compared with the manual transmission).

In the 718 GTS 4.0 models, the standard Sport Chrono package adapts the gear shift characteristics of the PDK according to the four different driving modes (Normal, Sport, Sport Plus and Individual).

In Sport mode, it operates with faster gear changes, shifts down earlier with automatic throttle blips, and supports optimal acceleration with later shift points.

The even more athletic Sport Plus mode is tailored for maximum performance and fully exploits the rpm reserves of the naturally aspirated six-cylinder boxer engine. Launch Control is also integrated within Sport Plus, which activates an automatic race start.

The Sport Response button in the centre of the mode switch allows the driver to activate maximum engine and transmission performance for 20 seconds, irrespective of the current driving mode. This motorsport-inspired function helps with spontaneous overtaking manoeuvres.

In the flagship 718 Spyder and 718 Cayman GT4 models, the driving mode has a characteristic that is typical of the GT variants.

It can be programmed for maximum performance using the PDK Sport button.

An automatic selector lever, which echoes the design in the 911 GT3, underlines the emotionally charged GT experience. The seventh gear of the PDK has a shorter ratio in all 718 four-litre naturally aspirated engine derivatives.

The PDK versions of the 718 Spyder and 718 Cayman GT4 also benefit from enhancements made to their mechanical locking rear differential. In traction and overrun modes, this achieves locking values of 30% and 37% as compared with 22% and 27% with the manual transmission. This has a positive effect on the longitudinal and lateral dynamics as well as traction, and increases driving pleasure.
