The accusations managed to reach the upper echelons of Nissan management, prompting representatives at last week’s Paris Motor Show to state emphatically that the times recorded for the GT-R around the Nurburgring were achieved "on absolutely standard tires which are available to customers in the showroom," and that any sort of slick tires were never used.
A Porsche chassis engineer took a standard GT-R bought in the United States with regular road tires, and tested it on the same day against a Porsche 911 GT2 and a Porsche 911 Turbo. According to Porsche, the GT-R posted a time of 7m 54s, with the 911 Turbo managing 7m 38s and the 911 GT2 getting down to 7m 34s.
Nissan offers proof that standard tires were used for the GT-R’s 7m 29s Nurburgring lap by releasing new video and image of actual tires used in the test
Speaking with Drive, Nissan's European spokesman Neil Reeve stated that Nissan continues to "absolutely maintain (that) Tochio Suzuki pounded thousands of laps and got to know every inch of the Nurburgring and hence set that fabulous lap.”
Reeves went on to comment that it was "flattering that Porsche have bought themselves a GT-R and flown it to Germany" for testing, but that "the people who'd buy a GT-R or 911 Turbo are not the type of people to make a purchase like that lightly.” He also reaffirmed that the GT-R has beat the 911 Turbo during a number of independent tests for both acceleration and circuit lap times.
Nissan has now released an image of the actual tires used for the test plus a second video of the lap as proof that its 7m 29s lap time is legitimate. In an official statement Nissan claims that “there are some important facts that were not accurately represented.”
Nissan has revealed that the GT-R used in the official lap time was actually at a disadvantage due to up to 50kg of testing equipment. According to GTRblog, Nissan has also offered free driver training for Porsche if it wants to attempt a second lap.
