Mercedes-AMG’s new GT R is the most extreme version of the AMG GT ever released, featuring a wider front and rear fenders, along with a new front fascia and large air intakes. Its unique grille is borrowed from the track-oriented AMG GT3, and it's matched by the large rear wing and exclusive green paint job as some of the more distinctive features. The car weighs in at 3,428 pounds, using aluminum alloys for the chassis and body, magnesium for the front deck and steel for the trunk lid. Additionally, there's carbon fiber at the front fenders, roof, and torque tube between the engine and transmission.
Performance wise, the Mercedes-AMG GT R packs a familiar twin-turbo 4.0-liter V-8 used on standard GT models, though it's been tuned to generate 577 hp and 516 lb-ft of torque. Backed by a seven-speed dual clutch transmission, the rear-wheel-drive car is able to hit 60 mph in an estimated 3.5 seconds, with a top speed of 198 mph.
The manually adjustable coil-over suspension is designed for the track has AMG Ride Control adjustable adaptive dampers. As for the aforementioned rear-steering system, the rear wheels are turned in the opposite direction of the front wheels at speeds up to 62 mph, resulting in a virtual shortening of the wheelbase to enhance agility when cornering. Above that speed, the system turns the rear wheels in the same direction as the front wheels, corresponding to the opposite effect, a virtual lengthening of the wheelbase and improving handling and stability.
The 2018 Mercedes-AMG GT R will arrive in the U.S. in the back half of 2017, with pricing to be announced.
