Inspired by the Green Hell

It is a car inspired and bred from the world’s most technical and demanding race track. Prior to its introduction into the global arena, the boys from Affalterbach wanted a sports car that packed enough punch to knock out any comers from Italy, Japan and the United States.

Never before has AMG packed so much motorsports technology into a production car than into the all-new AMG GT-R. AMG also stated that this vehicle is at the totem pole of the AMG fleet. “Our sports-car and performance brand AMG has its roots in motorsport and, ever since its formation, has repeatedly faced up to the competition on the racetrack. These genes are particularly prevalent in the new AMG GT R. Boasting a wealth of technological innovations, the new top-of-the-range model is proof of the close collaboration between our constructors of racing cars and road-going vehicles,” states Professor Thomas Weber, Member of the Board of Management of Daimler AG, responsible for Group Research and Mercedes Benz Cars Development.

AMG GTR side: The car sits low to the ground for better traction

This front-mid-engined beast with transaxle sports car comes equipped with a twin-turbo V8 rated with a 585bhp engine, and sits on a heavily modified suspension system to keep the car glued to the ground. AMG engineers even went as far as giving the car more aerodynamics and an intelligent lightweight construction to give it that edge when it goes head-on against the World’s supercars. It is wrapped in a special “AMG Green Hell Magno” color scheme to visually reveal the car’s origins and where it spent most of its development, the Nurburgring.

“With the new AMG GT R, we have reached the next level of driving performance. This road-going sports car with motor-racing genes and innovative technical solutions offers an ultimate driving experience that allows people to feel our motorsport origins in every fiber. It combines the driving dynamics of our AMG GT3 racing car with the everyday practicality of the AMG GT. Those with petrol in their veins will be thrilled by the radical longitudinal and lateral acceleration, the precise turn-in, and the sensational grip. We have modified all performance-relevant components and linked them together intelligently for maximum driving dynamics,” says Tobias Moers, CEO of Mercedes AMG GmbH.

 AMG GTR rear: The rear wing helps in keeping the car glued to the ground at high speeds

Wider front and rear wings allow an increased track width for optimum grip and even higher cornering speeds. The new front fascia with active elements, the large rear aerofoil and the new rear fascia with double diffuser enhance aerodynamic efficiency and help ensure optimum grip. The lightweight forged wheels shod with cup tires as standard are likewise designed for maximum driving dynamics. The same applies to other new features such as the active rear-wheel steering, the nine-way adjustable traction control system and the adjustable coil-over suspension with additional electronic control. What is more, the new AMG Panamericana grille emphasizes the unique standing of the AMG GT R. Its characteristic form with vertical fins celebrated its world première on the Mercedes AMG GT3 customer-sport racing car and now for the first time features on an AMG production vehicle.

Looks fast even when parked 

2017 Mercedes Benz GTR: The “Shark Nose” front end and green color are the distinct features of the Benz GTR

The distinctive “shark nose” and low-slung front section, plus forwards-inclined radiator grille make the car appear to sit lower on the road. At the same time, this shape lowers the vehicle’s back-pressure point, enhancing the flow of cooling air and the car’s aerodynamic performance.

The wide front splitter reduces lift at the front axle. Additional Air Curtains on the outside of the front fascia calm the airflow, improving the Cd value of the AMG GT R. Thanks to their narrow, vertical openings, the Air Curtains also guide the air specifically towards the wheel arches, optimizing the flow properties in this area. To ensure ideal airflow through the double wheel arch radiators, the AMG GT R additionally features new and unique wheel arch liners with special cooling-air slits.

AMG GTR engine: This twin turbo V8 pumps out 585bhp

A special engineering feat is the completely new active aerodynamics profile, which is concealed almost invisibly in the underbody in front of the engine. At a speed of 80 km/h in RACE mode, this carbon component, weighing only about two kilograms, automatically moves downward by about 40 millimetres and changes the airflow considerably. This process results in what is known as the Venturi effect, which additionally “sucks” the car onto the road and reduces the front-axle lift by around 40 kilograms at 250 km/h.This innovation was developed using computer simulation at first and then optimized during many hours in the wind tunnel. The results were confirmed in extensive test drives, including on the North Circuit of the Nurburgring. 

The suspension of the new AMG high-performance sports model is also systematically designed for racetrack use. Wishbones, steering knuckles and hub carriers on the front and rear axle are manufactured entirely out of forged aluminium in order to reduce the unsprung masses. The double-wishbone concept locates the wheel firmly, with minimal elastic movements. The high camber and toe-in stability results in high cornering speeds and also provides the driver with an optimum feel for the road when cornering at the extreme limits.  Photos by AMG AG
