It's hard to imagine two machines that offer a more different approach to going very fast than the GT2 and the GT-R, and the disparity only widens when the weather turns lousy. The GT-R, with its clever all-wheel-drive system, should offer a far more secure experience, but the fact that we're already in the conditional tense should give you a clue as to what is really the case. In the wet and the damp, and on a cold surface that denies it the tire temperature it needs to operate to its proper abilities, the GT-R feels every bit as big as its 3882 pounds suggest. Like the GT2, either axle will relinquish grip at any time, but the lack of longitudinal adhesion is only the most surprising problem. The main issue here is that, for anyone who has experienced its extraterrestrial abilities, the GT-R is loaded with expectations - you expect it to fashion something from nothing - but a wet Nürburgring vanquishes its indomitability. It's still far more drivable than something so heavy and large has any right to be, but on the treacherous slippery sections that had the GT2 instantaneously slithering a car width to the outside of a turn, the GT-R's greater mass forces it out even farther. We complete two laps like this, and they aren't especially pleasant. Then, with no warning, the clouds disperse, beams of sunlight pierce the gloom, and within minutes, wisps of vaporized water are rising from the track. At this rate, there will be something approaching a dry line at the very end of the day. There won't be time to build up to a fast lap, though; instead, it will be a case of an out lap, a flyer to set a time, and then an in lap to de-jangle the nerves. At the very least, it will make for an even contest: a driver who knows the circuit well and the shortest possible timeframe in which to get the job done. The GT2 may have had an advantage in the wet, but with the GT-R's dual clutch transmission and sticky Bridgestones on a dry surface, it will surely be possible to extract a greater percentage of the GT-R's performance potential.
Nissan claims that the GT-R can lap the 'Ring in 7 minutes, 29 seconds, wearing the original-equipment Dunlop tires that are about 5 seconds per lap faster than the also-original-equipment Bridgestones on this car. Porsche claims the GT2 will run a 7-minute, 32-second lap. Given the low temperatures, the few damp patches on the circuit, and the fact that, unlike the guy who set the Porsche's time, I haven't won a World Rally Championship, we don't expect to match the manufacturers' claims, but we should get a very good idea of which car is faster.
