Nissan GT-R, more horsepower than paid for
Back in the 60s and even 70s, musical car manufactures (American) would sometimes give official horsepower ratings that were less than what the engine actually put out. This was done in combination to help owners with insurance prices as well as gain a good reputation on the dragstrip (after all, you’d rather have your car over-perform than under-perform.) According to Car and Driver, these times might be back. The magazine strapped five Nissan GT-Rs to a dyno to confirm what the automotive press has been suspecting all-along – the GT-R has been underrated.
Car and Driver first had their suspicions that the GT-R was being bashful when it could beat out a Corvette Z06 despite having a 30 percent worse power to weight ratio. Once strapped to the dyno, the five different GT-Rs (remember each engine is specifically made for the individual car and transmission) made close to 415 horsepower at the wheels. This translates into an engine that’s putting out about 520 horsepower, which is a nice jump from Nissan’s claim of 480 horsepower.
