The new 2010 Porsche 911 GT3 RS has unofficially lapped Nurburgring Nordschleife in 7min 33sec. That's still significantly slower than the current leaders, which include the Corvette ZR1 (7m26.4s), Gumpert Apollo (7m11.57s), Radical SR8LM (6m48s) and the highly disputed Nissan GT-R (7m27.56s), however, compared to the regular 911 GT3 it is a full seven seconds quicker.

The test driver was not named, however, track conditions were reported as having "some light traffic" and the timer telemetry showed a theoretical best lap of 7m 30s.

It was a year ago Porsche disputed Nissan's claims of achieving 7m 29s with the newly launched Nissan GT-R which was 20 kilos heavier than the 911 Turbo. Porsche officials were baffled as they could only achieve 7m 54s with a GT-R they purchased from the US. Porsche suspected the GT-R had been modified or used other tires. Nissan fired back by releasing photos of the tires used as well as in-car video footage with timer display. Since then Nissan has gone on to better the GT-R's time further with 7m 26.7s.
