Nissan just ruined Porsche's summer vacation. Instead of having some quiet time to work on the 998 generation of the 911->ke1920, Porsche is now going to have to try and recapture bragging rights at the Nurburgring from the 2010 GT-R.

There has been some bad blood between Porsche and Nissan lately over the legitimacy of the 2009 GT-R's 7m 29s run around the Ring. Porsche claims the car was heavily modified, and Nissan claims Porsche is a sore loser over the slower GT2.

Just to prove its point, Nissan took a 2010 GT-R (which got a 5 hp bump and a few other minor tweaks) back to Germany. The result: a lap time of 7m 27.56s, which now even beats Porsche's top ring time of 7m 28.71s in a Carrera GT.

Nissan says it's not done making lap record attempts. The next stop is the Corvette ZR1's 7m 26.4s time, but that's still a far cry from the production car top spot of the Dodge Viper ACR's 7m 22.1s.

Press release after the jump.

Press release

The all-conquering Nissan GT-R supercar has set another lap record at the famous Nurburgring Nordschleife in Germany.

A Japanese specification GT-R, running on Dunlop tyres with RAYS forged alloy wheels (V-spec equipment) recorded a blistering 7min 27.56 secs yesterday.

Driven by Nissan's Chief test driver Toshio Suzuki (who recently demonstrated the GT-R to the Australian media in Sydney at Eastern Creek Raceway) piloted the performance coupe.

Although dry, the track surface grip was impaired by dust and sand. Under the direction of Nissan GT-R Chief Vehicle Engineer, Kazutoshi Mizuno, and depending on conditions, the Nissan test team will attempt another record at the 'Ring tomorrow.
