The GT-R name has been synonymous with Nissan for a long time, but the three letters truly gained popularity with the R32 Skyline GT-R. The car was so advanced, it gained the nickname "Godzilla," because it could destroy everything. Fast forward to today and the GT-R Nismo is the most hardcore version of Nissan's sportiest model. Even though the GT-R is extremely meaningful to Nissan, it doesn't seem like the company protected that name. That's because Mercedes came out with a hardcore version of its AMG GT sports car, calling it the GT R.

Like the Nissan, the Mercedes has a nickname, "The Beast From The Green Hell." The GT R set a 7:10 lap time around the Nurburgring, while the "older" Nissan was able to lap the track in 7:08.

Motor Trend wanted to find out which of these GTR models is best. Johnny Lieberman and Randy Pobst (filling in for Jason Cammisa) bring the cars to Mazda Raceway Laguna Seca to find out if those Nurburgring times are legit. The duo have a hunch that those Nurburgring times are so close, that it may have been down to one of the drivers just having a bad day. Around Laguna Seca, the Mercedes held the advantage because of its R compound tires and ceramic brakes. The Nissan GT-R has been on the market for a long time, but it is still very competitive. Yet the AMG GT R may have overtaken the Nissan as Motor Trend's favorite GTR.
