"Y'all can't drive"...that's what Nissan is subtly saying at Porsche, its engineers and its test driver after the Germans claimed Nissan cheated during GT-R Nurburgring test run.

Nissan has responded to claims by Porsche that the Japanese company cheated by using non-standard, semi-slick tyres on its record run at the ‘Ring earlier this year. Porsche had bought a Nissan GT-R in the US to test claims that the car had become the fastest around that world famous track, and their cars beat the GT-R’s time. The two cars used were a 911 Turbo and a GT2. Now Nissan has given some free advice to the likes of Porsche.

“We are aware that several auto makers have purchased the GT-R for their own testing and evaluation,” said a statement from Nissan. “Like all GT-R customers, we recommend that any auto maker buying a GT-R should follow the recommended run-in procedures, service schedules and maintenance to ensure the maximum performance from their car. In addition, we offer performance driving courses for prospective and current GT-R owners to help them get the best performance from their car. We would welcome the opportunity to help any auto manufacturer with understanding the full capabilities of the GT-R.”

Additionally the contested rubber used is still in Nissan’s possession and is used for promotional purposes. An offer to view it is open to any non-believers. Nissan continued to say testing the GT-R with additional equipment and/ or non-standard modifications would be pointless to them. “The GT-R was designed from the start to be a supercar that could be driven anywhere, anytime and by anyone,” says chief engineer Kazutoshi Mizuno.

In fact, goes Nissan, had it not been for the extra 50kg or so of weight it carried in order to record the record lap run, the GT-R would have been even quicker. Is this the end of this spat of the giants?
