watching and listening to that video, I can honestly say 3 things:
1. the car is more powerful than 480hp... more likely, 580hp... the acceleration on the straights and the way it pulls out of the corners makes me think that they had that car turned up something fierce.
2. that car is not on street tires... the "wet" spots would not have affected street tires on that track... but they would have affected slicks... that, combined with how the tires sound when they are in the corners, makes me think that this car has some big rubber underneath it.
3. that car is niiiice... the awd system is VERY well balanced... they have obviously put alot of time and effort into making that system adapt to fast speeds and tight cornering... something that previous generations could not always say.
all in all, I think that the new GT-R will be a helluva car... but some of the hype is undeserved... and some of the claims need to be challenged... anyone notice that GM, Ford and others have not challenged this time? nobody but Nissan is touting this as any kind of big achievement? if you were selling the Z06, the GT, the 997 turbo, etc., why wouldn't you, as a big manufacturer, call BS on this? I'm guessing there's more to all of this that Nissan is hiding... and that GM and others know about already... none of us are ever going to get the full story about this run... but it is real and it was done... but there is nothing to support the quarter mile run... maybe someone testing with a G-Tech Pro? lol
all in all, nice car and definitely world class... I wouldn't buy one, but its definitely going to raise the bar... especially for AWD cars
