Still Not Convinced? Nissan Reveals Second GT-R 'Ring Video

TOKYO — After officially refuting claims from Porsche that cheating was involved during Nissan's tests of the GT-R at the Nürburgring earlier this year, Nissan has further proved its point by revealing a second video of the iconic sports car in action.

The time of 7 minutes and 29 seconds was disputed by Porsche engineers, who insisted that the vehicle must have been equipped with special tires after only managing 25-second-slower lap times when they tested it.

The video clearly shows Nissan's chief test driver Tochio Suzuki making the 7-minute, 29-second lap, and the Japanese automaker has even offered images of the actual tires used in the test.

Inside Line says: Even the biggest GT-R skeptics can't deny the cold, hard facts now presented by Nissan. — Mike Lysaght, Correspondent
