Motor Trend pits their new 2013 Nissan GT-R Black Edition long term test car up against the 2012 Porsche 911 Turbo S. This may not seem like a natural comparison, but both of these cars have twin turbocharged 3.8 liter V6’s powering all wheel drive systems. Nissan has been incrementally upgrading the GT-R every year since its release. Starting in 2012, they really killed the car’s natural tendency to understeer and a lot of people declared that they had given the car a soul. The 911 Turbo S costs $71,000 more than the GT-R. Even though the naturally aspirated 911 moved to the new 991 chassis this year, the turbo is still on last year’s 997 chassis. Johnny Lieberman flogs both cars on Mulholland drive, then drag races them and hits the standard performance tests.
