The new Mercedes-AMG GT R.
The front-mid-engine concept with transaxle, the twin-turbo V-8 engine rated at 430 kW/585 hp, the extensively modified suspension, the new aerodynamics and the intelligent lightweight construction all lay the foundations for an especially dynamic driving experience. Even from afar, the exclusive “AMG green hell magno” special paintwork leaves no doubt as to the sports car’s origin, having spent most of its development time in the “Green Hell” of the Nürburgring racetrack. Wider front and rear wings allow an increased track width for optimum grip and even higher cornering speeds.
Spearhead of AMG.
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 new AMG Panamericana grille emphasises the unique standing of the AMG GT R. Its characteristic form with vertical fins celebrated its world première on the Mercedes‑AMG GT3 Customer Sports racing car and now for the first time features on an AMG production vehicle.
The third member of the AMG GT family is the new spearhead of the AMG model range. Featuring pioneering technologies, the AMG GT R was designed with racetrack use firmly in mind. Figures such as 3.6 seconds from zero to 100 km/h and a top speed of 318 km/h, combined with the outstanding driving dynamics, will undoubtedly translate into extremely fast laps on the racetrack.
Sharpened racetrack performance comes courtesy of the intelligent lightweight construction incorporating aluminium and carbon, specific reinforcements in the body shell, the uprated twin-turbo V-8 engine with the specifically adapted seven-speed dual-clutch transmission, the innovative aerodynamics with active components, and the new suspension with active rear-wheel steering and uniball joints. The concept with front mid-engine and transmission in transaxle configuration on the rear axle, a tried-and-tested feature of the AMG GT and AMG GT S, makes for a beneficial rear-biased weight distribution. In conjunction with the vehicle’s low centre of gravity, this translates into extremely agile handling and permits high cornering speeds. With a power-to-weight ratio of 2.66 kilograms per hp, the Mercedes-AMG GT R takes up pole position in its segment.

Enhanced driving dynamics.
Aerodynamics engineers and designers worked together more intensively than ever during development of the new AMG GT R. All elements have an inherent technical benefit and contribute to the enhanced driving dynamics, while the aerodynamics experts have made the designers’ wishes a reality. 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 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 front-axle lift by around 40 kilograms at 250 km/h.
The driver can feel this in the steering: the AMG GT R is even more precise to steer when cornering at high speed and exhibits even better directional stability. In addition, the drag coefficient is improved.
All of the aerodynamic measures combined increase the surface contact at top speed by 155 kilograms compared with the AMG GT. The new AMG GT R therefore offers maximum grip, perfect drivability and a powerfully proportioned design that integrates the aerodynamic functions harmoniously. And there’s more: despite its higher engine output, extra width, chunkier tyres, larger rear aerofoil, raised cooling-air demand and increased downforce, the AMG GT R has a lower drag coefficient (Cd) than the AMG GT.
The new AMG coil-over suspension was designed specifically for the AMG GT R. Like in professional motorsport, drivers can select their personal set-up and infinitely adjust the spring pre-load manually. This makes it possible to influence the dive and roll behaviour as well as the grip of the AMG GT R precisely. The coil-over suspension is combined with the AMG RIDE CONTROL continuously variable, adaptive damping system.
The system is electronically controlled and automatically adapts the damping on each wheel to the current handling situation, the speed and the road conditions. Furthermore, the driver can adjust the adaptive damping characteristics at the touch of a button in the AMG DRIVE UNIT or by using the AMG DYNAMIC SELECT transmission modes. Three modes are available: “Comfort”, “Sport” and “Sport Plus”.
Easier to control at the limit.
The new AMG GT R is even more sensitive to steering inputs thanks to standard-fit active rear-wheel steering, which is being used for the first time on a Mercedes-AMG model. The system offers an ideal combination of agility and stability ‑ handling characteristics that are normally in direct conflict. The active rear-wheel steering not only improves cornering, it also assists the driver in the event of sudden evasive manoeuvres and thus enhances active safety, This makes the AMG GT R easier to control at the limit.
The standard 3-stage ESP® with the settings “ESP ON”, “ESP SPORT Handling Mode” and “ESP OFF” works in perfect unison with the limited-slip differential and is optimally tuned to the outstanding driving dynamics of the AMG GT R.
Traction under control.
In ESP OFF mode, another innovation allows the driver to exert even more influence on the handling characteristics of the AMG GT R. The new AMG TRACTION CONTROL system also comes directly from motorsport. It allows drivers to pre‑select the slip on the driven rear axle in nine levels. Just like in the current AMG GT3, it isolates the grip on the driven wheels and does not affect the stabilisation provided by the ESP®. Corresponding characteristic maps are programmed into the vehicle electronics to this end. Control is via a special rotary switch located in the centre console below the ventilation outlets. Depending on the setting, the system permits more or less slip on the rear wheels ‑ very helpful in varying road conditions.
Mercedes-AMG uses an intelligent material mix for the structure of the AMG GT R: various aluminium alloys for the chassis and body, steel for the boot lid and magnesium for the front deck. A host of further measures contributes to the weight reduction as part of the AMG lightweight-performance strategy. The use of carbon fibre, the lightweight and high-strength material from motorsport, helps to achieve the ambitious goals. Carbon fibre is the material of choice for, among other things, the front wings, the roof and the torque tube between engine and transmission. Overall the new AMG GT R is 15 kilograms lighter than the AMG GT S, despite incorporating far more technical features.
The AMG 4.0-litre twin-turbo engine in the AMG GT R has an output of 430 kW (585 hp), which is 55 kW (75 hp) more than the previous top-of-the-range engine in the GT S. The peak torque of 700 Nm is available between 1,900 and 5,500 rpm. The AMG 4.0-litre V-8 engine features the tried-and-tested twin turbochargers, which are not mounted on the outside of the cylinder banks but rather inside the V configuration – experts call it a “hot inside V”. This basic principle of the new AMG V-8 family has been further optimised for the AMG GT R. The seven-speed dual-clutch transmission configured in a transaxle layout at the rear axle has likewise been extensively revised by the AMG developers to make the transmission even more suitable for the racetrack. Drivers can tailor the AMG GT R to their personal preferences using the AMG DYNAMIC SELECT controller. Various modes are available: “C” (Comfort), “S” (Sport), “S+” (Sport Plus) and “I” (Individual). The “RACE” mode optimally adjusts the shift strategy of the dual clutch transmission to the needs of racetrack usage.
By pressing the separate “M” button in the centre console, the driver can activate the manual transmission mode in any transmission mode.
