Mercedes-AMG GT R premiered to great fanfare with a 585 PS V8 bi-turbo beast of an engine and an aero-kit made in Heaven. Now, Gustavo Estrada, the man in charge with Mercedes-AMG’s Aerodynamics department explains how that trick aero kit works.
At the front, the big star is the carbon fiber piece which automatically descends at a speed of 80 km/h (50 mph). The active aerodynamic solution reduces lift on the front axle by replicating the Venturi effect. The percentage is impressive: 50 percent at full speed. The balance between lift and downforce makes the AMG GT R feel more agile and easier to control when cornering at high speeds. The same active carbon fibre front apron works in tandem with two vertical air curtains for sending more cold air to the brakes.
The Venturi effect is the reduction in pressure that results when a fluid or air flows through a constricted section. It is named after Giovanni Battista Venturi (1746–1822), an Italian physicist.
At the rear, a massive diffuser steals the show. But not only in terms of road presence. The diffuser optimizes air flow and can increase the stability of the rear axle. Time to see Mr. Estrada explain what he created.
Mercedes-AMG GT R, the most potent sports car in AMG’s portofolio today, is powered by the biturbo 4.0-liter V8 of its GT S brother, boosted to 585 PS or 577 hp, 75 PS more than the Mercedes-AMG GT S. Compared to the GT S torque also increases by 50 Nm to 700 Nm. The GT R must be able to reach a speed of 100 km/h in 3.6 seconds. It’s also 0.2 seconds quicker than the GT S. Top speed is 318 km/h.
Besides additional spoilers, the “beast of the Green Hell” will feature a special color: Green Hell AMG Magno. Also brand new for the Mercedes-AMG GT R are the lighweight alloy wheels, modified brakes, suspension and steering ratio and last, but not the least, the huge fixed rear wing and front grille which pays homage to the W194 300SL Gullwing race car from 1954.
