Planet 9

(FAQ in Process)

Derived from motorsport, PDK, available for the 911 Turbo for the first time, achieves one thing above all else: it provides the perfect balance between uncompromisingly dynamic performance and exceptional levels of comfort. It’s purely about point of view. The driver’s especially.

The optional PDK with both manual and automatic modes enables extremely fast gear changes with no interruption in the power flow. For improved acceleration and significantly lower fuel consumption – without having to dispense with the advantages of an automatic.

The driver experiences a sportier, even more dynamic drive with more agility. Depending on driving style, gear changes range from exceptionally comfortable to exceptionally sporty.

Manual gear changes are performed using the PDK’s ergonomically designed gear lever or the switches on the steering wheel: nudge forwards to change up, pull back to change down. The logic behind the optional three-spoke sports steering wheel with gearshift paddles comes from motorsport: pull to the right to shift up, pull to the left to shift down.

PDK has been specially tuned to the characteristics of the new 911 Turbo models. It has seven gears at its disposal. Gears 1 to 6 have a sports ratio, with the top speed being reached in 6th gear. The 7th gear has a long ratio and helps to reduce fuel consumption even further.

PDK is essentially two half-gearboxes in one and thus requires two clutches – designed as a double wet clutch transmission.

This double clutch provides an alternating, non positive connection between the two half-gearboxes and the engine by means of two separate input shafts (input shaft 1 is nested inside the hollowed-out input shaft 2).

The flow of power from the engine is only ever 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, a conventional shift no longer takes place. Instead, one clutch simply opens and the other closes at the same time. Gear changes can therefore take place within milliseconds.

Clutch 1 controls the first half-gearbox, which contains the odd gears (1, 3, 5, 7) and reverse. Clutch 2 controls the second, which contains the even gears (2, 4, 6).

The optional Sport Chrono Package Turbo with dynamic engine mount system provides PDK with two additional functions, ‘Launch Control’ and ‘motorsport-derived gearshift strategy’.

PDK – sporty, comfortable and efficient. Characteristics that have been given some thought elsewhere too: in the specification for the new 911 Turbo models.
