Mercedes-AMG GT4 Facelift Ready for Homologation

More than half a year after introducing the facelifted GT3, Mercedes-AMG are now ready to show an updated version of the successful GT4 model. This is the younger brother of the GT3, and it too will see some new design and technical optimisations for the 2020 model year.

Expect better engine and brake cooling on this facelifted GT4 model.

Here’s the press release with more.

PRESS RELEASE

363 races, 137 podium finishes, 151 class wins and 53 overall wins: the record of the Mercedes-AMG GT4 since its market launch in 2018 is quite impressive. In the past two years, the ‘little brother’ of the Mercedes-AMG GT3 advanced to one of the most successful cars in the booming GT4 segment worldwide. So far, the performance and sports car brand from Affalterbach 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 even further extends 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 as well as enhanced engine cooling. Both the enlarged brake air inlet as well as the dimensionally stable brake air lines with larger diameter 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. Thanks 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 instance, 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.

Market launch in the 2020 motorsport season

The market launch of the new Mercedes-AMG GT4 will follow in March, 2020 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. 

Stefan Wendl, head of Mercedes-AMG Customer Racing: “When we entered the GT4 segment two years ago, it was our aim to build a car that was capable of winning right away. 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.”
