Similar to a manual shifter, the individual gears are selected using shift forks in the PDK system, it’s done through computer-aided electrohydraulics. ![]() The technology enables fully automatic gear changes without traction interruption. The odd gears and reverse are connected to clutch I, while the even gears are connected to clutch II. In the PDK, the gears are distributed between two separate clutches-hence the name. Initial trials with the new technology starting in 1980 culminated in a signal achievement in 1986. By now there’s little sign of the initial backlash against the alleged mismatch between sportiness and automatic technology-and that’s down to the Porsche dual-clutch transmission (PDK). Needless to say, the Sportomatic package was not a rousing sales success.įast-forward half a century. ![]() Comfort? In a sports car? And on top of that, two seconds slower from 0 to 100 kmh than with manual? As if all that wasn’t enough, it also had a higher fuel consumption. The omission of the clutch pedal was intended to enhance the car’s comfort. Even reserved Porsche fans registered their consternation. Back in 1967, when Porsche first offered the 911 with a semiautomatic Sportomatic transmission, it wasn’t just dyed-in-the-wool brand purists who were dismayed the trade press was equally skeptical.

This results in improved acceleration when compared with a traditional manual or automatic.ĭual-clutch transmissions are also more efficient. Using this arrangement, gears can be changed without interrupting power flow from the engine to the transmission.įirstly, the transmission is never disconnected from the powertrain, allowing much quicker gear changes. One clutch controls odd gears (first, third, fifth and reverse), while the other controls the even gears (second, fourth and sixth). These clutches are controlled by a series of sophisticated electronics meaning that there is no need for the driver to use a clutch pedal. Both clutches operate different gears, allowing for gear changes without disconnecting the engine from the transmission. ![]() In a vehicle with manual transmission, the driver has to press down the clutch pedal, which briefly interrupts power flow in order to change gears.Ī dual-clutch vehicle has no pedals and two clutches.
