Apparently, according to
Jalopnik, driving your GTR on any kind of race track now voids the warranty, as does putting it on a dyno. I am personally quite put-off by Nissan's handling of the GTR. I'm convinced that the pre-production vehicles used to set all of these amazing performance numbers were running higher-boost. They launch the car with a list price of $69,xxx and within 12 months, raise the price to $87,xxx. They promote its 1/4-mile and 0-100 times, all obtained using launch control but then don't allow the owners to do likewise. Now, if you cannot take the car to your local track day for hot laps without voiding your warranty, WTF is this car good for?
Nissan's comparison to the 911 is bunk - Porsche
wants you to take your 911 to the track and enjoy it for what it was made to do - high performance driving. Porsche is the real thing when it comes to high performance cars and driving, Nissan is a poser.
