Known as the Green Hell or more simply the Ring, the Nurburgring Nordschleife is considered the longest and most challenging racetrack in the world. Automotive manufacturers and speed demons place a high premium on Nurburgring lap times. So when the Nissan GT-R shattered the Porsche 911's record with a blistering 7:29:03 lap time earlier this year, a few feathers were ruffled in Stuttgart, Germany.
So what did Porsche's engineers do about it? Well, they went out, purchased a brand new GT-R, and drove it back to back with a 911 Turbo and a 911 GT2 in an attempt to duplicate Nissan's results. After testing, Porsche is claiming that Nissan somehow cheated and that the GT-R's true lap time is some 25 seconds slower. What gives?
According to Porsche, Nissan's lap vehicle was no mere production vehicle, but rather a "wonder car." More specifically, Porsche is claiming that the GT-R in question was equipped with semislick racing tires, instead of stock tires as Nissan claims. Official video of the GT-R's lap was filmed in vehicle and, of course, the tires can't be seen.
Nissan hasn't released a comment.
Update 10/03: Says Nissan, "The final word from us is that it was done on absolutely standard tires which are available to customers in the showroom. They're not trick tires - absolutely standard tires, normal road tires."
