Porsche 911’s PDK dual-clutch improves Nurburgring lap time

Yes, it’s very exciting to hear that the Nissan GT-R did 7:29 at the famous Nurburgring Nordschleife circuit. It’s even a little more exciting to hear that an American car, our new and beloved 2009 Cadillac CTS-V, was the fastest production sedan to lap the circuit in 7:59. 

However once a huge Nurburgring champion, Porsche has been keeping a low profile about its Nurburgring numbers. Now the Germany automaker has posted times for its 2009 Porsche 911 at a media event in Germany flaunting its new Porsche Doppelkupplung (PDK) double-clutch 7-speed automatic gearbox.

According to Porsche, the 2009 911 Carrera S with PDK turned a lap of time of 7:50. The 2009 Porsche 911 Carrera S with a manual transmission was 8 seconds slower at 7:58.  Comparing it to the current 911 Carrera S with manual transmission (which came in at 8:02), PDK improves the 911’s Nurburgring lap by a total of 12 seconds.

Porsche says that its new PDK dual-clutch 7-speed automatic is 60 percent faster than the Tiptronic S automatic. Not to mention it offers better fuel-economy as well. Without PDK, the Carrera gets a combined fuel-economy of 21.3mpg in U.S. standards – with PDK the Carrera gets 24mpg.
