Without Porsche’s new double-clutch 7-speed automatic PDK transmission, the Carrera Coupe gets a combined fuel-economy 21.3mpg – with PDK the Carrera gets 24mpg. Great - it increases fuel-economy; but what about performance?

According to Porsche the new PDK dual-clutch 7-speed automatic is 60 percent faster than the Tiptronic S automatic. In a recent test at the Nurburgring, the 2009 911 Carrera S with PDK returned a lap of time of 7:50. The 2009 Porsche 911 Carrera S with manual transmission was 8 seconds slower at 7:58.

So PDK is the definitely the way to go even if you’re a true stick fan. Check out this review by our friends at CAR.

    As a reader of CAR, I enjoy their articles. I wonder though, and I might be the only one, whatever happened to showing intricate cut-aways and explaining in detail new technologies. Motor Trend and Car & Driver both used to do this. I often do wonder about new transmissions, and how does variable valve timing work in a pushrod engine, it is not going to have the different lobes and rockers as Honda's VTEC.
