Back in the late sixties, automakers sometimes purposely under-reported the true horsepower that their solid-lifter, over-cammed and over-carburetor'd monster V8 engines actually delivered. More recently, some manufacturers have overestimated the real power of their vehicles, which has led some to distrust factory horsepower numbers. Owners of the uber-impressive Nissan GT-R have been wondering if they've been lied to regarding real horsepower figures too. But in this case they may actually be getting more than the 480 horses that they had bargained for. In fact, after considering that the coupe is capable of hitting 123 miles per hour in the quarter mile and the fact that it weighs roughly four-thousand pounds, the New York Times Wheels blog estimates that the GT-R really makes 550-580 horsepower at the crank.

While we are certain that the rabid horsepower wars and the debate over the GT-R's true power as compared to its rivals will rage on, NYT's estimates are actually pretty much in line with what Motor Trend got after putting the Nissan supercar on the dyno, and that's a figure that really can't be argued with. Thanks for the tip, Pete!
