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 gearbox, very short response times, reduced fuel consumption and a distinct increase in comfort.
In total, PDK has seven forward gears at its disposal. Gears 1 to 6 have a sports ratio and top speed is reached in 6th gear.
The 7th gear ratio is longer and keeps engine speed low to improve ride comfort and reduce fuel consumption at higher speeds.
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 pre-selects 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.
With the optional Sport Chrono Package, PDK is enhanced by the ‘Launch Control’ and ‘motorsport-derived gearshift strategy’ functions (p. 65) for even faster and firmer gear changes and the best possible performance thanks to a boost in torque during upshift phases. Overrun downshifts provide extremely sporty braking and acceleration for added excitement.
