German car manufacturer Porsche have recenty introduced PDK (Porsche Doppelkuppungsgetribe) or Double clutch gearbox in their facelift 911. It’s a development of a system used some 20 years ago in their 24 Hours Le Mans cars so its taken a while to filter through!

The gearleaver or steering wheel paddles can be used to change the ratios. With a 60 percent increase in shift speeds, compared to the old tiptronic system, this looks to be a realistic contender as a favourite choice.

This times in nicely with the launch of the revised facelift 998 bodyshape which you can see below.
