he seven-speed PDK – fitted as standard in the Panamera 4, Panamera 4S and the Panamera Turbo models and available as an option in the Panamera and Panamera S – has both a manual gearshift and an automatic mode and enables smooth gear changes with no interruption in the flow of power. Gears 1 to 6 have a sports ratio and top speed is reached in 6th gear. The 7th gear has a long ratio, which reduces fuel consumption even further and keeps engine revs comfortably low even at high road speeds.
PDK is essentially two gearboxes in one and this requires two clutches. 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 transmitted through one half gearbox and one clutch at a time, while the next gear is pre-selected in the other half gearbox. During a gear change, therefore, a complete 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 a few hundredths of a second.
PDK has distinct benefits, including a high level of driving comfort and very rapid gearshifts for faster acceleration. Driving feels even sportier and more dynamic, and agility is increased. Depending on the gearshift programme (SPORT button activated or deactivated), the gear change is optimised for comfort or for sporty driving. Its high level of efficiency, combined with the long-ratioed 7th gear, helps to achieve reduced fuel consumption and emissions figures, even when compared with a standard manual gearbox.
In conjunction with the optional Sport Chrono Package, PDK is enhanced by a Launch Control function which offers a sportier acceleration and gearshift strategy in automatic mode and extremely smooth gear changes in manual mode.
PDK offers sportiness with efficiency and comfort.
