Mercedes-AMG GT4: a new version of the famous model


Following the launch of the new GT3 racing car, Mercedes-AMG is introducing the next iteration of the world-famous GT4 model. In addition to the updated design, the Mercedes-AMG GT4 has undergone technical optimizations to improve performance in endurance racing, among other things. With improved engine and brake cooling, the new GT4 can reliably deliver peak performance even in extremely hot temperatures.

363 races, 137 podium finishes, 151 class wins and 53 overall wins: the list of achievements of the Mercedes-AMG GT4 since its market launch in 2018 is truly impressive. Over the past two years, the "little brother" Mercedes-AMG GT3 has established itself as one of the most recognizable racing cars in the growing GT4 segment worldwide. To date, the high-performance sports car brand Affalterbach has delivered more than 120 units to private teams. With the new incarnation of the GT4, Mercedes-AMG is further raising the level of competitiveness of its highly acclaimed car.

Better engine and brake cooling

The benefits of the new Mercedes-AMG GT4 include optimized front axle brake cooling as well as a more efficient engine cooling system. Both the larger air intake that cools the brakes and the dimensionally stable, larger diameter air ducts prevent overheating of the brake system components. The result: better driving performance and reduced wear, especially important in endurance racing. A new carbon fiber air duct, well-matched thermal insulation and optimized clamp adapters improve airflow around heat-sensitive components. Optimized brake cooling is complemented by newly developed front axle discs designed for increased reliability and longer life. A new oil cooler arrangement, as well as a new carbon exhaust duct and a new bonnet contour made of natural fibre-reinforced material, contribute to even more efficient cooling of the time-tested 4.0-litre AMG V8 biturbo engine. As a result, the Mercedes-AMG GT4 can reliably maintain its performance even at extremely high temperatures.

New lighting concept

The Mercedes-AMG GT4 update also includes redesigned front and rear lights to match the modules used in the Mercedes-AMG GT3. Their design matches the current road-going versions of the Mercedes-AMG GT. In addition to the updated design, the new lighting concept also has practical advantages: the new high-performance LED headlights provide much better illumination of the track. In the dark or in conditions of poor visibility, this offers decisive advantages in terms of safety and productivity.

Optimized Control

Another optimization carried out concerns the modification of the rear wishbones, which are also similar to those used on the new GT3. They have a much longer service life. The result is a Mercedes-AMG GT4 that, among other things, three class wins at the 24 Hours of Nürburgring makes it even better prepared to compete in endurance marathons. Another new feature of the 2020 GT4 is the use of a larger brake fluid reservoir, optimized for the specific requirements of endurance racing.

The highest safety standards

In addition to further technical development, the Mercedes-AMG GT4 has been distinguished by a number of advantages since its introduction to the market, including exceptionally high safety standards. A safety cage made of high-strength steel is bolted to the aluminum space frame, and there is a hatch in the roof. The carbon fiber driver's roll cage with integrated headrest offers a much higher level of protection than traditional racing seats. An effective fire extinguishing system completes the comprehensive safety concept. The proven racing electronics used in the GT4 are easy to operate and maintain. The car was equipped, for example, with a special traction control system and multifunctional ABS. These systems are based on GT3 technology, as is the variable differential sequential gearbox. Double wishbone suspension and sag and rebound dampers provide very precise handling and exceptional responsiveness. The innovative torque control system of the V8 biturbo engine guarantees precise dosing and delivers the desired response. As a result, drivers of all skill levels quickly gain confidence in their vehicle.
