The GT R is a high-performance variant of the Mercedes-AMG GT and was revealed at the Goodwood Festival of Speed on 24 June 2016. The M178 engine in this variant is tuned to an output of 577 hp and 516 lb-ft of torque. The GT R accelerates from 0 to 100 km/h (62 mph) in 3.6 seconds and has a claimed top speed of 198 mph (319 km/h). While the GT R retains the key mechanical differences the GT C gains over the GT S, it also gains manually adjustable coilover springs (in conjunction with the AMG Ride Control suspension of its lesser siblings), an active underbody fairing, a manually adjustable rear spoiler, and a 9-mode AMG Traction Control system. As befitting of a high-performance variant, the GT R loses Keyless-Go, the integrated garage-door opener, the heated / power-folding side mirrors, the auto-dimming interior / exterior mirrors and reverts to the basic light-weight 4-speaker audio system that the GT comes with. When it was launched, the GT R had several cosmetic changes compared with the standard car, notably the vertical slats in the front grille, a fixed rear wing, new front air intakes and new front and rear diffusers. The styling of the GT R is more comparable to that of the AMG GT3 race car. However, the standard car gained several of these cometic changes as part of a mild facelift in the 2017 model year. The GT R went on sale in November 2016, with deliveries beginning in 2017. It completed a lap of the Nürburgring Nordschleife track in 7:10.92, in a test conducted by German magazine Sport Auto. he GT and GT C roadsters are the roadster versions of the GT and GT C coupés, and were announced shortly after the GT R variant. Both variants made their debut at the 2016 Paris Motor Show. The GT and GT C roadsters utilize the active air management system found on the GT R variant to help with cooling and airflow performance. The GT C roadster retains the wider bodywork of the GT C coupé, and the GT roadster has a slightly higher first and lower seventh gear
