The automaker has unwrapped the Mercedes-AMG GT R in its official presentation of the model that took place in front of the audience of the Goodwood Festival of Speed.
This is the third and to date most spectacular and performance-oriented member of the AMG GT roster, with the best numbers to date coming from the upgraded powertrain and lower weight. Following a lengthy and mostly quite revealing teaser campaign, the Mercedes-AMG GT R is official now in its green glory – a reference to the Nurburgring Nordschleife circuit – also dubbed the Green Hell. It appears the long wait was worth it, with the specialists from Affalterbach bringing a lot more pound for weight that we would have expected. The biturbo 4.0-liter V8 engine has been massaged for a serious power bump while the car itself went to the gym to lose quite a few pounds. Now the new AMG GT R tips the scales at 3,428 pounds (1,554 kilograms), bringing savings of 199 lbs (90 kg) compared to the S variant.
Additionally, Mercedes’ competitor for the Porsche 911 and Audi R8 unleashes from under the hood no less than 577 horsepower (430 kilowatts) and 516 pound-feet (699 Newton meters) of torque thanks to the updates of the engine – packing another 74 hp & 37 lb-ft on top the S offering. The oomph is directed towards the rear wheels via a dual-clutch, seven-speed sports transmission, which has been tweaked to cope with the better credentials of the R. The first gear is now slightly longer, while the seventh gear is shorter in order to turn better acceleration characteristics. This enables the AMG GT R to sprint to 60 mph (96 km/h) in just 3.5 seconds, 0.2 seconds faster than the S version. It’s also subtly faster, now topping out at 198 mph (318 km/h).
The design is augmented by the bespoke “AMG green hell magno” paint which can only be ordered on the R, with the Mercedes-AMG GT R also being treated to the tweaked styling, We noticed an AMG Panamericana grille inspired by the GT3 racer, wider carbon fenders (+1.8 inches) as well as enlarged air intakes needed to secure better cooling. Other changes include a wider front splitter for less front axle lift, the large wing at the back and the underbody has been completely changed and now comes with active aerodynamics. It has a 4.4-lbs carbon component which can automatically position itself lower by about 1.6 inches to improve airflow when the car is doing 50 mph (80 km/h) in RACE mode. There’s also a new exhaust system for better soundtrack and lower weight – it’s 13 lbs (5.9 kg) lighter and there’s also rear-wheel steering for the first time on a Mercedes-AMG model. The Mercedes-AMG GT R has a standard electronically-controlled limited-slip differential on the rear axle and benefits from an upgraded carbon-fiber torque tube which is about 40 percent lighter than in the standard models. Optionals also include the ceramic composite braking system which further reduces weight by 37 lbs (16.7 kg).
Inside the car Mercedes-AMG has opted for standard AMG performance seats clad in Nappa leather and DINAMICA microfiber, with optional yellow seatbelts. Other highlights include yellow trim on the instrument cluster dials, along with a piano black lacquer finish and special controls – such as the traction control buttons with nine selectable settings.
