Available as an option for the Boxster models is 7-speed Porsche Doppelkupplung (PDK), featuring both manual and automatic modes. PDK offers extremely fast gear changes with no interruption in the flow of power, improved acceleration over the manual transmission, very short response times, reduced fuel consumption and a distinct increase in comfort.
The design of PDK is similar to two conventional gearboxes in one. The odd numbered gears are housed on one assembly and the even numbered gears on another, each having its own clutch. While one gear is engaged, PDK preselects the next gear based on driver input. When the next gear is requested, drive is switched from one clutch to the other in milliseconds, delivering gear changes with no loss of drive.
With the SPORT button selected, the full advantages of PDK are brought into play: a more immediate response to throttle inputs, even shorter shift times and swift, throttle-blip downshifts on overrun and when braking – always accompanied by an emotive engine sound.
When combined with the optional Sport Chrono Package (standard in the Boxster GTS), gearshifts are sportier, shift times shorter. Other gearshift strategies are also available – for uncompromising driving enjoyment.
