It’s arrived, AMG’s latest weapon, the very Green 2018 Mercedes-AMG GT R, design to go head to head to head with Porsche’s 911 GT3 RS. At it’s heart is a handcrafted AMG 4.0L V8 Biturbo with output of 577 hp, which is 74 hp more than the previous top-of-the-range engine in the GT S. Peak torque of 516 lb-ft is available between 1,900 and 5,500 rpm.

The increase in performance was achieved with the help of new turbochargers with modified compressor machining, a smaller wastegate and new engine mapping. Boost pressure supplied by the turbochargers has been increased from 17.4 psi on the AMG GT to 19.6 psi. In addition, the exhaust ports have been optimized and the compression ratio modified.

The seven-speed dual-clutch transmission has been extensively revised by AMG, with modified hardware and  software to make the transmission even more suitable for the racetrack. First gear in the AMG SPEEDSHIFT DCT 7-speed sports transmission has a longer ratio, while seventh gear and the final drive have shorter ratios to allow for more rapid acceleration.

 

Expect savage performance due to the liberal use of weight saving aluminum and carbon fiber. Mercedes estimates 0-60 in 3.5 seconds but we believe it will be quicker. The specially developed exhaust system not only delivers genuine racing car sound, it also saves around 13 lbs. of weight compared with the AMG GT S thanks to the use of titanium for the rear silencer and thin-walled stainless steel for the front section of the exhaust system.

Drivers can tailor the AMG GT R to their personal preferences using the AMG DYNAMIC SELECT controller. Various modes are available: “C” (Comfort), “S” (Sport), “S+” (Sport Plus) and “I” (Individual). The “RACE” mode optimally adjusts the shift strategy of the dual clutch transmission to the needs of racetrack usage – shortest shift speeds and highly emotional engine sound are included. By pressing the separate “M” button in the center console, the driver can activate the manual transmission mode in any drive mode.

Conventional suspension measures include the wider front and rear track as well as the standard-fit Michelin Pilot Sport Cup 2 tires, of size 275/35 ZR 19 at the front and 325/30 ZR 20 at the rear. The street-legal racing tires allow faster laps and up to 50 percent more mileage on the racetrack.

The interior is also strongly inspired by motorsport. AMG Performance Seats (also equipped in the AMG GT S) are covered in Nappa leather and DINAMICA microfiber come as standard. They offer good lateral support even in extreme driving maneuvers. The optional yellow seat belts, dials with yellow highlights, the AMG Black Piano Lacquer interior trim and special controls, including those for the new AMG TRACTION CONTROL, underline the unique standing of the new AMG GT R.

The new AMG Interior Night package will also be available. In this package, the shift paddles, steering wheel bezel, door sills and trunk cross member are finished in high-gloss black, which combines with the standard-specification AMG Interior Piano Lacquer package to further emphasize sportiness. As an option, customers can order the trim in matte black carbon fiber.

The car is expected to arrive in US dealers by mid- 2017.
