Aerodynamic Mastery: Form Follows Function
The development of the Mercedes-AMG GT R witnessed unprecedented collaboration between aerodynamics experts and designers. The AMG design philosophy of “Dynamic Presence” forms the foundation for its more aggressive and athletic appearance. In the AMG GT R, form and function are inextricably linked; every design element serves a technical purpose, contributing to enhanced driving dynamics, while aerodynamicists successfully translated the designers’ vision into reality. This synergy even resulted in patented innovations.
The AMG Panamericana grille immediately commands attention. This distinctive feature, originating from motorsport, makes its production debut in the AMG GT R. Its 15 chrome-plated vertical fins are directly inspired by the new AMG GT3 racing car. The grille’s fundamental shape pays homage to the Mercedes-Benz 300 SL racing car, a victor of the legendary 1952 Panamericana road race in Mexico, connecting the GT R to a rich racing heritage.
Front-End Aerodynamics: Unbridled Thrust
The AMG GT R’s low-slung front section and forward-leaning radiator grille create a distinctive “shark nose” profile, visually lowering the car and enhancing its assertive stance. This design also optimizes airflow by lowering the vehicle’s back-pressure point, improving cooling and aerodynamic performance.
The more pronounced V-shape and arrow-like design of the front end amplify the dynamic aesthetic, visually conveying the AMG GT R’s relentless forward momentum even at a standstill. The front fascia, featuring a completely redesigned jet-wing design inspired by the A-wing, broadens the perceived width and gives the car a more grounded appearance. The large outer air intakes, reminiscent of jet engines, are not merely stylistic; they are crucial for meeting the AMG GT R’s increased cooling demands. These intakes incorporate two aerodynamically optimized horizontal fins that effectively channel airflow to the radiators.
The wide front splitter plays a vital role in reducing lift at the front axle. Additional Air Curtains positioned at the outer edges of the front fascia manage airflow, contributing to an improved drag coefficient for the AMG GT R. These narrow, vertical openings precisely direct air towards the wheel arches, optimizing airflow in this critical area. To ensure efficient airflow through the double wheel arch radiators, the AMG GT R features unique wheel arch liners with specialized cooling-air slits.
Active Underbody Aerodynamics: Venturi Effect Innovation
A groundbreaking feature is the active aerodynamics profile, ingeniously integrated within the underbody ahead of the engine. In RACE mode and at speeds above 50 mph, this carbon component, weighing a mere 4.4 lbs., automatically extends downwards by approximately 1.6 inches, dramatically altering airflow. This deployment generates the Venturi effect, effectively “sucking” the car closer to the road and reducing front-axle lift by around 88.2 lbs. at 155 mph.
This aerodynamic innovation translates directly into enhanced steering feel and precision, particularly during high-speed cornering. The AMG GT R exhibits even greater directional stability and responsiveness. Especially during aggressive cornering and under high lateral acceleration, the AMG GT R delivers remarkably agile responses with clear steering feedback, while maintaining exceptional control at all times. Furthermore, this system contributes to an improved drag coefficient without compromising downforce on the rear axle.
This pioneering technology was developed using advanced computer simulations and refined through extensive wind tunnel testing. Real-world validation was conducted during rigorous test drives, including sessions on the demanding Nürburgring Nordschleife. The active aerodynamics profile remains discreetly concealed within the underbody, seamlessly integrating with the car’s overall silhouette.
When the electrically operated profile extends, the radiator air outlet at the front opens, precisely directing airflow towards the double rear diffuser, optimizing its efficiency. This enhances rear-axle handling stability and reduces heat build-up in critical rear components. The aerodynamics package also contributes to optimized braking performance by channeling more cool air directly to the wheel discs. To prevent damage, the carbon component is spring-mounted, allowing it to flex upwards upon encountering obstacles.
Active Air Management: Louvers for Optimized Airflow
Another key aerodynamic enhancement is the active air management system, featuring vertical louvers positioned in the lower front fascia, directly behind the grille. These electronically controlled louvers can open and close within a second, adjusting airflow to optimize aerodynamic performance and cooling efficiency.
Normally, the louvers remain closed, even at top speed, during braking, and during high-speed cornering. This closed position minimizes drag and directs air towards the underbody, further reducing front lift. The louvers open only when predefined component temperatures reach critical thresholds and cooling demand is high, allowing maximum cooling airflow to the heat exchangers. The comprehensive aerodynamics strategy of the AMG GT R ensures an optimal balance between lift and downforce across all driving conditions, while achieving a lower drag coefficient compared to the AMG GT and GT S models.
Side Profile: Powerful and Elongated
The front fenders, crafted from lightweight carbon fiber, add 1.8 inches to the AMG GT R’s front width, accommodating the wider track and larger wheel and tire combinations. These sculpted fenders accentuate the car’s dynamic, elongated profile. A distinctive fender vent, featuring a stylized fin and a large air outlet for engine bay heat, further differentiates the GT R. This fin is perforated and incorporates the AMG diamond logo with five slats, adding a signature detail.
The side view is further enhanced by optional AMG Performance forged wheels in matte black. These exceptionally lightweight 10-spoke wheels, exclusive to the AMG GT R, feature a complex design including a drop-center rim, a milled groove, and two high-sheen rim rings of varying widths. The front wheels measure 10.0 J x 19, while the rears are 12.0 J x 20. The lightweight design of these wheels delivers multiple benefits: reduced overall weight, lower rotational mass, and decreased unsprung mass.

The rear end of the AMG GT R showcases numerous distinctive innovations. New aluminum side walls widen the rear by 2.2 inches, creating space for larger 20-inch wheels and a wider track. These changes improve traction and enable higher cornering speeds. The wider rear fascia design, with large outer vent openings and vertical swaging, optimizes airflow at the rear, as does the double diffuser. The double diffuser also enhances heat dissipation from the exhaust system during driving.
A small air outlet integrated between the tail lamps further aids in dissipating heat generated by the rear silencer. Another defining feature of the AMG GT R is the large exhaust tip with a central spar, positioned centrally in the rear fascia. It is flanked by two additional black exhaust tips integrated into the diffuser on either side.
The large, fixed rear wing, mounted on the hatch, significantly increases downforce on the rear axle. The aerofoil mounts are painted in body color, while the blade is finished in high-gloss black. The blade angle is manually adjustable, a motorsport-derived feature allowing for fine-tuning based on track conditions or driving style.
The combined effect of all aerodynamic measures results in a 342 lbs increase in surface contact at top speed compared to the standard AMG GT. The Mercedes-AMG GT R achieves maximum grip, exceptional drivability, and a powerfully proportioned design that seamlessly integrates aerodynamic functions. Remarkably, despite its increased power output, wider body, larger tires, substantial rear aerofoil, enhanced cooling demands, and increased downforce, the AMG GT R boasts a lower drag coefficient (Cd) than the AMG GT.
AMG Coil-Over Suspension: Individualized Track Setup
The suspension of the AMG GT R is meticulously engineered for racetrack performance. Wishbones, steering knuckles, and hub carriers on both front and rear axles are constructed entirely from forged aluminum to minimize unsprung mass. The double-wishbone design ensures precise wheel location with minimal elastic movement. High camber and toe-in stability contribute to exceptional cornering speeds and provide the driver with optimal road feedback at the limits of grip.
Uniball spherical bearings on the lower wishbones of the rear axle, inspired by motorsport technology, are significantly more durable than conventional wishbone bushings. Their zero-play design ensures that toe-in and camber remain consistent even under extreme loads, allowing for even greater driving precision in the AMG GT R. A thicker tubular anti-roll bar at the rear axle, adapted to the heightened dynamic demands of the AMG GT R and utilizing a hollow design for weight savings, further enhances handling.
The new AMG coil-over suspension is specifically developed for the AMG GT R. Mirroring professional motorsport setups, drivers can fine-tune their personal suspension settings and manually adjust the spring pre-load. This allows for precise adjustments to dive and roll behavior, and grip levels, tailoring the car’s handling to individual preferences or specific racetrack characteristics.
The coil-over suspension is paired with the AMG RIDE CONTROL continuously variable, adaptive damping system. This electronic system automatically adjusts damping at each wheel based on driving conditions, speed, and road surface. Damping characteristics are modulated rapidly and precisely by separate valves for rebound and compression forces within the dampers. Increased damping rates during cornering and braking effectively minimize body roll. Continuous damping adjustments based on speed ensure optimal road contact even at high velocities, enhancing safety.
Drivers can adjust the adaptive damping characteristics via a button on the AMG DRIVE UNIT or through the AMG DYNAMIC SELECT drive modes. Three damping modes are available: “Comfort,” “Sport,” and “Sport Plus.” “Comfort” is optimized for public roads, “Sport” is ideal for demanding tracks like the Nürburgring Nordschleife with undulating surfaces, prioritizing maximum ground contact and dynamic driving. “Sport Plus” is tailored for smoother, modern Grand Prix circuits like Hockenheim, conveying a high degree of structural rigidity.
Conventional suspension enhancements include wider front and rear tracks, and standard Michelin Pilot Sport Cup 2 tires, sized 275/35 ZR 19 at the front and 325/30 ZR 20 at the rear. These street-legal racing tires enable faster lap times and offer up to 50 percent greater mileage on the racetrack.
Active Rear-Wheel Steering: Agility and Stability
The Mercedes-AMG GT R boasts standard active rear-wheel steering, a first for a Mercedes-AMG model, enhancing steering responsiveness. This system delivers an optimal blend of agility and stability, handling characteristics that are typically at odds with each other.
Two steering actuators replace conventional control arms on the rear axle. The core of the system consists of two electro-mechanical actuators (electric motors with jackscrew) that are electronically controlled and not mechanically linked to the steering wheel—a “by-wire” system. This system adjusts rear wheel toe angle within a predefined operating range, with a maximum change of 1.5 degrees on the rear wheels of the AMG GT R.
At speeds up to 62 mph, the rear wheels steer in the opposite direction to the front wheels, effectively shortening the wheelbase. This enhances agility when cornering, resulting in greater driving enjoyment and reduced steering effort, particularly on tight, winding roads, narrow racetracks with frequent direction changes, or during slalom maneuvers. Benefits also include improved maneuverability and a tighter turning circle in everyday driving, especially when parking.
Above 62 mph, the system steers the rear wheels in the same direction as the front wheels, virtually lengthening the wheelbase and improving handling stability. Lateral force build-up on the rear wheels becomes significantly faster during direction changes, quickening steering response. Drivers experience enhanced rear axle grip and stability during rapid direction changes, eliminating the twitchiness often felt at the rear end.
Active rear-wheel steering not only improves cornering performance but also assists during sudden evasive maneuvers, enhancing active safety, and making the AMG GT R more controllable at its performance limits. The standard 3-stage ESP® system, offering “ESP ON,” “ESP SPORT Handling Mode,” and “ESP OFF” settings, works seamlessly with the limited-slip differential and is finely tuned to the AMG GT R’s exceptional driving dynamics. The ESP OFF mode programming is derived directly from the AMG GT3 race car.
AMG TRACTION CONTROL: Grip to the Power of Nine
In ESP OFF mode, the new AMG TRACTION CONTROL system, another motorsport-derived innovation, allows drivers to further fine-tune handling characteristics. This system enables pre-selection of rear-axle slip in nine levels. Like the AMG GT3, it isolates grip control on the driven wheels, without interfering with ESP®-provided stabilization. Specific characteristic maps are programmed into the vehicle’s electronics.
A dedicated rotary switch located on the center console below the ventilation outlets controls the system. Depending on the selected level, the system permits varying degrees of slip on the rear wheels, highly beneficial in changing road conditions. Level 1 provides maximum safety reserves for wet conditions, while Level 9 allows for maximum rear-axle slip. An illuminated LED band around the rotary switch indicates the current setting, mirroring motorsport display logic. The setting is also displayed in the instrument cluster’s central screen.
The AMG system distinguishes itself from conventional systems by predicting situations using a virtual µ(mu) simulator and other data processed by a control unit in milliseconds. The maximum permissible slip on the driven rear wheels is calculated based on the selected AMG TRACTION CONTROL level. When wheel slip reaches this threshold during acceleration, the traction control modulates engine output to maintain the specified slip level and ensure continuous acceleration. The electronic limited-slip differential’s effect is also incorporated into the adjustment range. This lag-free control enhances both driving enjoyment and performance. The system also assists in optimizing engine torque and torque increase when accelerating out of corners, crucial elements for achieving fast lap times.
Electronically Controlled Rear-Axle Limited-Slip Differential
The AMG GT R comes standard with an electronically controlled limited-slip differential on the rear axle, integrated into the compact transmission housing.
