Porsche PDK: Automation & Fuel Efficiency

I was harping on about wanting PDK in my next toy, and thought I’d better find out what it actually is! And probably more importantly – is it any good?

Porsche PDK, (Porsche Doppelkupplungsgetriebe), which simply means Porsche double-clutch gearbox, was initially developed for motor sports. It was developed to benefit drivers both in terms of both speed and acceleration by allowing them to change gears while still keeping both their hands on steering wheel. Seems like a great idea to me!

The great thing about this new gearbox from Porsche is that it offers 7 forward gears. The combination of manual gear shifting facility with a torque converter, facilitates transmission and makes PDK quite special. PDK is an upgraded (and most definitely smoother) version of the previously available Porsche Tiptronic system.

Porsche PDK helps to improve both acceleration and fuel efficiency. PDK’s automatic transmission system helps it to stay ahead of the game from manual clutch gear boxes, due to the combination of manual gearbox as well as a hydraulic control unit. These are separated into two unique transmission units containing two clutches placed in a radial arrangement. The clutch that has uneven gears – 1, 3, 5 and 7 along with the reverse control is the first transmission part whereas the one with even gears – 2, 4, 6 is the second transmission part.

Disengagement of one clutch automatically engages the other clutch on the other transmission. This brings about a noticeably nicer gearshift feeling in the mind of driver and facilitates faster gearshift. The results are really quite noticeable. I like it!!

Minimizes Power Loss

The Porsche 911’s PDK system is also fantastic for controlling power loss during transmission. Its inbuilt double clutch mechanical efficiency brings about an increase in fuel economy, which can only be a good thing in times when fuel prices are at a premium. You can have an average fuel rate increase of about 13% as compared to the Tiptronic S gear box.

Another added advantage of having a PDK vis-a-vis Tiptronic S, or manual shifts is that despite of having 2 extra gears, it is around 10 Kg less in weight.

Speed is, of course what any Porsche is about (even the Cayenne Diesel lol) and Porsche’s PDK units ability to shift gears 60% faster than other transmission equipments makes it s a perfect match for the any of the new models. Being able to deliver better performance along with greater fuel economy = win win from Porsche!

Some Quick Facts about PDK

  • Shifts gears at 60% greater speed as compared to conventional transmission equipments
  • PDK equipped Carrera models can accelerate within 4.5 seconds from a speed of 0 mph to 62mph
  • Can be combined with motor sports related packages to offer high speed acceleration– like the Sport chrono Package Plus.
  • Comes at a price of only £2,338 extra.

So, Porsche’s PDK is gets my vote -  amazing gear box that offers you a superb combination of speed, acceleration, automatic transmission and fuel economy. Its a bit of an understatement to say that PDK would be on my options list at the local Porsche Centre.
