The proven production technology of the front-mid engine allows for particularly long service intervals and also provides sufficient performance reserves for the future. Depending on the balance of performance, this results into an output of up to 503 hp (375 kW) and a maximum torque of over 443 lb-ft (600 Nm).

Like in the Mercedes-AMG GT3, the sequential six-speed competition gearbox in the Mercedes-AMG GT4 is linked to the rear axle in transaxle formation and is pneumatically operated. This arrangement results into a favorable weight distribution and a lower center of gravity. A differential that is adjustable from the outside optimizes the driving characteristics for the specific requirements of competition use. In the construction and the integration of the gearbox, the focus of the development was not only on performance, but also on service and rebuild ease.

To achieve maximum performance at the race track, the Mercedes-AMG GT4 has been weight-optimized in every area. An intelligent mix of aluminum and carbon has been used for the chassis and the bodywork. The structure of the GT4 consists of a very light and extremely rigid aluminum spaceframe that can also be found in the Mercedes-AMG GT R and that has been honored with the 'Leichtbau Award 2017,' an innovation award from the German engineers' association VDI. As a part of the AMG Lightweight Performance Strategy, further measures and optimizations of details contribute to the weight reduction. Thus, racing-specific bodywork parts such as the hood, the front bumper or the front splitter have been made of a particularly lightweight composite material. In the production version of the GT R, carbon is already used as a material for the front fenders and the torque tube between the engine and the gearbox.

The Mercedes-AMG GT4 has adopted the proven safety concept of its 'big GT3 brother' and is thus setting new benchmarks in its class. The best possible driver protection has the highest priority. Here, the rollcage of high-strength steel and the aluminum spaceframe play a central role. The carbon driver safety cell meets the latest FIA homologation standards and features an integrated headrest. Optionally, this is also available for the passenger seat. Because of its design, the safety cell also provides a very high level of protection for a driver's shoulders, hips and legs. Moreover, it is compatible with the HANS (Head And Neck Support) system. An extrication hatch in the roof and a powerful fire extinguishing system round out the competition- specific safety features.

Ergonomics and functionality can be found in the interior of the Mercedes-AMG GT4: all the elements, systems and displays have been designed in such a way that less experienced drivers can also handle them quickly. In the large cockpit, even tall drivers find sufficient space, especially as the steering wheel has a wide adjustment range and the pedals can be adjusted as well. For easy handling and good visibility in the dark, the controls on the steering wheel are illuminated as are the large switches on the center console that is orientated towards the driver. The effective circulation of fresh air in the interior is particularly pleasant for the driver and, to allow the drivers to keep cool in all racing conditions, air conditioning is available for the Mercedes-AMG GT4 as an option.

The electronics of the Mercedes-AMG GT R were revised to meet the requirements of the GT4 race car. A durably high user and service friendliness complements reliable operation under extreme pressure. Customer Racing Teams that are familiar with the Mercedes-AMG GT3 will particularly benefit as they will find proven menu structures and solutions. The racing engine control unit is the digital heart that guarantees an exact performance. A new torque control allows for excellent measurement and drivability. Further highlights include an optimized version of the AMG TRACTION CONTROL that enables the driver to adjust the slip on the rear axle in eleven levels to suit varying grip conditions.

The highly precise driving characteristics rank among the outstanding features of the Mercedes-AMG GT4. The suspension, with double wishbones and dampers with adjustable rebound and compression, gives direct and clear feedback to the driver in every situation. Drivers of every level quickly find confidence in the car as a result. Moreover, the Mercedes-AMG GT4 convinces with exact steering response, outstanding agility and excellent traction. A powerful competition brake system with multi-adjustable ABS ensures maximum stopping power. The Mercedes-AMG GT4 is equipped with 18 inch forged AMG light-alloy wheels.

The new Mercedes-AMG GT4 is bringing the characteristic design of its production counterpart to the race track. The unmistakable features include the flat front section with the radiator grille that is tilted to the front. This lay- out lowers the stagnation pressure point on the car to improve both the aerodynamic performance and the flow of the cooling air through the hood. All other design elements of the Mercedes-AMG GT4 are focused on the technical benefit and add to the overall performance. The aerodynamics are playing a leading role: building on the innovative aerodynamic concept of the Mercedes- AMG GT R, the race car was further optimized in a comprehensive wind tunnel test to achieve a handling that is as neutral as possible. Like this, it is easier for the teams to find an individual track set-up. To this end, the rear wing of the GT4 car has a very wide adjustment range to select the required combination of low drag and high downforce levels. At the aerodynamically optimized front, a wide splitter reduces the lift on the front axle, to which the flics mounted to the side of the front bumper contribute as well.

The boom of the GT4 class was initiated in Europe and is reflected in a rapidly increasing number of opportunities for competition, be it with exclusive GT4 formats or as separate vehicle categories within various series or events. Currently, the following series can be considered as the most important 'hunting grounds' for the new Mercedes-AMG GT4: the IMSA Continental Tire SportsCar Challenge and the Pirelli World Challenge in the US, the Blancpain GT Series Asia in Asia and the Australian GT Trophy in Australia. In Germany, the VLN endurance racing championship and the Nürburgring 24-hours are the designated highlights for the new race car from Affalterbach. The GT4 European Series Northern Cup and the GT4 European Series Southern Cup are dedicated international GT4 series. The 24H Endurance Series also provides a large international platform for GT4 competition. Therefore, the new Mercedes-AMG GT4 is eligible to race at a large international platform where it can compete for victories and titles in the hands of the AMG Customer Racing Teams.
