Mercedes-AMG reveals new GT4 model for its Customer Racing Programme

11 March 2020

Following the launch of the new Mercedes-AMG GT3, Mercedes-AMG has now revealed its new GT4 model for the 10th anniversary season of its Customer Racing Programme. It features new design characteristics and technical optimisations that, among others, enhance the endurance racing performance.

Due to improved engine and brake cooling, the new Mercedes-AMG GT4 is also able to bring its top performance reliably to the track in extremely hot conditions. Once the homologation has been completed, the first new vehicle deliveries and update kits of the new model are being delivered in March.

Since its market launch in 2018, the model has been entered in 363 races, achieving 53 overall wins, 151 class wins and 137 podium finishes. To date, the performance and sports car brand from Affalterbach in Germany has delivered more than 120 examples of the race car to Customer Racing Teams all over the world. With the new edition of the GT4 that will be racing globally at tracks from March 2020 onwards, Mercedes-AMG is further extending the already high level of competitiveness of its successful model.

Improved brake and engine cooling

The particular advantages of the new Mercedes-AMG GT4 can be found in its optimised brake cooling around the front axle along with enhanced engine cooling. Both the enlarged brake air inlet along with the dimensionally stable and larger diameter brake air lines prevent the brake components from overheating. As a result, they ensure better driveability as well as considerably reduced wear of the brakes that are under particular load during endurance races.

Due to a new carbon brake air duct, adapted heat protection and optimised brake calliper adapters, the airflow through the thermally affected parts has been improved. A newly developed brake disc on the front axle, aimed at reliability and longevity, complements the optimised brake cooling. The re-arranged oil cooler contributes to an even more effective cooling of the proven AMG 4.0 litre V8 biturbo engine, just like the new carbon exhaust air duct and the newly shaped edge on the bonnet, made of natural fibre enforced material. As a result, the Mercedes-AMG GT4 can reliably deliver its performance, even in extremely hot conditions.

New light concept

The update of the Mercedes-AMG GT4 also includes optimised head and rear lights, identical to the corresponding units on the Mercedes-AMG GT3. Their design is in line with the current Mercedes-AMG GT road cars. Next to the fresh facelift look, the new light concept also comes with a practical purpose: the new LED high-performance headlights provide considerably better illumination of the track. In darkness or in poor visibility, this leads to decisive advantages for the drivers in terms of safety and performance.

Optimises handling for the teams

Another optimisation are the modified track rods on the rear axle that are also similar to those used on the new GT3 model and that come with a significantly extended longevity. As a result, the Mercedes-AMG GT4 that has, among others, already racked up three class wins in the Nürburgring 24-hour race, is even better prepared for endurance races in the toughest conditions. The integration of an enlarged brake fluid tank, optimised with the particular requirements in endurance races in mind, is also one of the novelties of the Mercedes-AMG GT4 for the year 2020.

Highest safety standards

In addition to the further development of the exterior and the vehicle technology, there is also a range of qualities that the Mercedes-AMG GT4 has stood out for from its earliest days, such as, for example, the particularly high safety standards of the vehicle. The roll cage of high-tensile steel has been bolted to the aluminium space frame and a recovery hatch has been integrated into the roof of the car. The carbon driver safety cell with integrated headrest provides a considerably higher level of protection than usual race seats. A powerful fire extinguishing system complements the comprehensive safety concept.

User- and service friendliness are also the characteristics of the proven competition electronics of the Mercedes-AMG GT4. For instance, the car comes with a competition-specific traction control and a multi-adjustable ABS. They are based on GT3 technology, just like the sequential competition gearbox with adjustable differential. The suspension with double wishbones and shock absorbers with adjustable bounce and rebound ensures a highly precise handling with unmistakable response. The innovative torque control of the V8 biturbo engine is a guarantee for accuracy and exact driveability. Drivers of all skill levels quickly build up confidence in the vehicle as a result.

The Mercedes AMG GT3 and GT4

Market launch in the 2020 motorsport season

The market launch of the new Mercedes-AMG GT4 will follow once the homologation has been completed. Orders for new cars can be placed with immediate effect. As the basic construction and the key components of the new edition of the GT4 are based on the current model, all the Mercedes-AMG GT4 built so far can be brought to the level of the new homologation (valid from March, 2020) without limitation and any problems thanks to a cost-effective update package.

“When we entered the GT4 segment two years ago, it was our aim to build a car that was capable of winning right away,” says Stefan Wendl, head of Mercedes-AMG Customer Racing:. “Looking at the achievements of the Mercedes-AMG GT4, we have succeeded in doing so in an impressive way.

“In order to enable our Customer Racing Teams to accomplish such top achievements at the race track in the future as well and to be prepared in the best way for the challenges in newly entered markets like Asia and South America, we have now decided to update the Mercedes-AMG GT4. The new edition combines performance, safety and economical aspects like no other car in this segment and has been tailor-made to meet the requirements of the customer teams. With its powerful V8 biturbo engine, the new Mercedes-AMG GT4 also guarantees plenty of fun away from the major international racing stage, be it during track days or in race series with open classes. The course for a successful future in the GT4 category has been set.”
