Mercedes-AMG is set to release a development of its GT4 model for the 10th anniversary season of its Customer Racing Programme.
The MY20 GT4 features new design characteristics and technical optimisations that enhance the endurance racing performance. Thanks to improved engine and brake cooling, the new GT4 also reliably bring its top performance to the track in extremely hot conditions. Once the homologation has been completed, the first examples of the new model will be delivered in March, 2020.
The 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 during endurance races.
Thanks to a new carbon brake air duct, adapted heat protection and optimised brake caliper 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 more effective cooling of the AMG 4.0 litre V8 biturbo engine, as do the new carbon exhaust air duct and the newly shaped edge on the bonnet, which are made of natural fibre enforced material.
The AMG GT4 update includes optimised head and rear lights, identical to the units on the Mercedes-AMG GT3 and in line with the current Mercedes-AMG GT road car design. 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.
Modified track rods on the rear axle are also like those used on the new GT3 model and offer significantly extended longevity.
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 fire extinguishing system complements the comprehensive safety concept.
The car comes with a competition-specific traction control and a multi-adjustable ABS that is 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 and response.
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 GT4s built so far can be brought to the level of the new homologation 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. 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, said head of Mercedes-AMG Customer Racing, Stefan Wendl.
“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.”
