Of course, you could let us take care of the gearshift strategy so that you can devote all your attention to your cornering strategy.

Available as an option is the completely retuned 7-speed Porsche Doppelkupplung (PDK), featuring both manual and automatic modes. The advantages are perceptible. Gear changes take place with no interruption in the flow of power. Sharper gearshift programs and significantly shorter shift times produce faster acceleration than with the manual gearbox. Fuel economy and comfort characteristics have also been optimised. In response to a less assertive driving style, shift points are recalculated to make use of the more comfortable and more economical engine speed ranges, and coasting mode is activated where possible.

This is how PDK works: PDK is essentially two gearboxes in one, thus requiring two clutches. This double clutch arrangement provides an alternating, non-positive connection between the two half gearboxes and the engine by means of two separate input shafts. The flow of power from the engine is transmitted through one half gearbox and one clutch at a time, while the next gear is preselected in the second half gearbox. During a gear change, therefore, one clutch simply opens and the other closes at the same time, enabling gear changes to take place within milliseconds.

PDK has seven forward gears at its disposal. Gears 1 to 6 have a sports ratio and top speed is reached in sixth gear. Seventh gear has a long ratio and keeps engine speed low to reduce fuel consumption and improve comfort.

With the SPORT button selected, the full advantages of the PDK are brought into play: a more immediate response to throttle inputs, relatively short shift times and swift throttle-blip downshifts on overrun, such as during braking into a corner, and always accompanied by an emotive engine sound.

With the optional Sport Chrono Package, PDK is enhanced by ‘Launch Control’ and the ‘motorsport-derived gearshift strategy’ for even faster and firmer gear changes and best possible performance, thanks to a boost in torque during up-shift phases. Overrun downshifts provide extremely sporty braking and acceleration for added excitement.
