Following the launch of the new Mercedes-AMG GT3, Mercedes-AMG presents the further development of its globally successful GT4 model for the 10th anniversary season of its Customer Racing Programme.

The new model year 2020 Mercedes-AMG GT4 features new design characteristics and technical optimisations that, among others, enhance the endurance racing performance.

The AMG-GT4 with optimised brake and engine cooling increases safety and performance
The improvements include ptimised brake cooling around the front axle and enhanced engine cooling. Both the enlarged brake air inlet as well as larger diameter brake air lines prevent the brake components from overheating, ensuring better driveability and considerably reduced wear of the brakes.

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. A re-arranged oil cooler also contributes to more effective cooling of the proven AMG 4.0-litre V8 twin-turbocharged 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.

Modified track rods trickled down from the GT3 provide the reliability it needs for endurance races
The update of the Mercedes-AMG GT4 also includes the modified track rods on the rear axle that are similar to those on the new GT3. Another optimisation is the head and rear lights. The new lights also serve a practical purpose, providing considerably better illumination of the track.

As a result, the Mercedes-AMG GT4 that has already racked up three class wins in the Nurburgring 24-hour race and is now even better prepared for endurance races in the toughest conditions.

The Mercedes-AMG GT4 has stood out for its particularly high safety standards since the early days. 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 driver safety cell is made of carbon fibre with integrated headrest that offers more protection
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 ensure a highly precise handling with unmistakable response. The innovative torque control of the V8 twin-turbo engine is a guarantee for accuracy and exact driveability.
