After launching the all-new Mercedes-AMG GT3 customer race car, Mercedes-AMG has updated its successful GT4 racer for the 2020 model year with a refreshed design and a slew of technical improvements to enhance its on-track performance. Since it launched in 2018, the Mercedes-AMG GT4 has competed in 363 races and achieved 137 podium finishes, 151 class wins, and 53 overall wins. In the last two years, more than 120 examples of the GT4 race car have been delivered to Customer Racing Teams across the globe.

Compared to last year's model, the 2020 Mercedes-AMG GT4 features optimized brake cooling around the front axle thanks to a larger brake air inlet and brake air lines that prevent the brake components from overheating during endurance races. Airflow is further improved thanks to a new carbon brake air duct, adapted heat protection and optimized brake caliper adapters further improve airflow.

Elsewhere, Mercedes-AMG has developed a new brake disc for the front axle and a re-arranged oil cooler provides better engine cooling. There's also a new carbon exhaust air duct and a newly shaped edge on the hood made of natural fiber enforced material to optimize performance during extremely hot conditions. Other optimizations include modified track rods on the rear axle similar to those used on the new GT3 that improve the handling and a larger brake fluid tank.

To give the styling a refresh, the new Mercedes-AMG GT4 has been fitted with restyled headlights and taillights that match the lighting units on the Mercedes-AMG GT3 and Mercedes-AMG GT road cars. New LED high-performance headlights also provide significantly track illumination when visibility is poor.

In terms of safety equipment, the 2020 Mercedes-AMG GT4 is equipped with a high-tensile steel rollcage, a recovery hatch integrated into the roof, an onboard fire extinguisher, and carbon driver safety cell with integrated headrest. The new GT4 also comes with a competition-specific traction control, and a multi-adjustable ABS. Power is provided by a 4.0 liter V8 twin-turbo engine producing 476 horsepower and 464 lb-ft of torque, which is sent through a six-speed sequential competition gearbox with adjustable differential. The suspension with double wishbones and shock absorbers with adjustable bounce and rebound ensures precise, responsive handling.

Mercedes-AMG is currently accepting orders for the new AMG GT4, with customer deliveries starting this month once the homologation has been completed. Owners of the current Mercedes-AMG GT4 can also add the same upgrades included in the 2020 facelift version thanks to a "cost-effective" update package.
