This extremely green car you see above is not simply a case of AMG throwing a bodykit and an engine tune at an AMG GT. Its AMG’s answer to the almighty Porsche 911 GT3 RS, and it’s packing some serious hardware in its quest to dethrone Porsche’s ultimate road-going track car. Hardware like active aerodynamics, bigger turbochargers, sticky tires, and active rear steering.


With the AMG GT-R, Mercedes-AMG is not screwing around. The car made its debut at a media event Friday before its big public reveal at the Goodwood Festival of Speed on Saturday. We’ve already seen the car teased and caught it testing at the Nürbugring, but now we have it in its over-the-top glory.AMG makes a big deal of the fact that this car was developed at the ‘Ring–the paint color is called “AMG Green Hell Magno.” The looks are quite different from the AMG GT S we’re all familiar with, all in the name of increasing track performance. The fenders are made out of carbon fiber and are 1.8 and 2.2 inches wider in the front and rear, respectively. They house Michelin Pilot Sport Cup 2 tires, the tire du jour for track cars.


As you’d expect, a liberal use of carbon fiber–notably in the fenders, roof, and driveshaft–helps reduce weight by 33 lbs over the standard GT S. That doesn’t seem like a lot, but AMG is quick to point out that all that new hardware would have otherwise incurred a weight penalty The engine also gets some upgrades over the 503-horsepower unit in the GT S. It’s the same 4.0-liter, dry sump twin-turbo V8 you’re familiar with, but new turbos and higher boost pressure bring power up to 577.

When we first saw pictures of the GT R in the Road & Track New York office, we were taken aback by the car’s oddball looks, but that’s not really the point. As AMG boss Tobais Moers said in a presentation, “form follows function, and function supports form.”

While the GT S is designed to be a elegant sports tourer, the GT R is designed to knock the Porsche 911 GT3 RS off its throne. We cant wait to drive it and find out how it does.
