2013 PORSCHE 911 GT3 gearbox

Thrust I 27
This is how it works. PDK is essentially
t wo gearboxes in one and thus requires
t wo clutches. This double clutch
arrangement provides an alternating,
non­positive connection between the
t wo half gearboxes and the engine by
means of t wo separate input shafts.
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. Highly responsive and especially sport y – just as you would
expect of the 911
GT3.
That in itself has consequences, not least
for acceleration, for overall performance
and for fuel economy. Positive conse ­
quences in fact. Driving feels even more
dynamic and agilit y is increased.
What about the gear changes them ­
selves? You’ll feel them and you’ll hear
them. Just like before, or indeed more
than ever. The electronic gearbox control logic of the Intelligent Shift Program (ISP)
offers more immediate and faster traction
­
induced upshifts and throttle ­blip down ­
shifts on overrun. In PDK SPORT mode,
downshifts under braking are more
aggressive while, under acceleration, the
shift points are raised even further. So
changing up a gear becomes a physical
experience – and an emotive one.
Shift fast without a moment ’s hesitation.
Just like the professionals.
