2017 Mercedes-AMG GT R – Driving (Good Exhaust Sound). The heart of the new high-performance athlete is pumping stronger than ever: the AMG 4.0-litre V8 twin-turbo engine in the AMG GT R has an output of 585 horsepower (430 kW), which is 75 hp (55 kW) more than the previous top-of-the-range engine in the GT S. The peak torque of 700 Nm is available between 1900 and 5500 rpm.
The increase in performance was achieved with the help of new turbochargers with modified compressor machining, smaller wastegate aneroid capsule and sharpened engine mapping. The boost pressure supplied by the turbochargers has been increased from 1.2 bar in the AMG GT to 1.35 bar. In addition, the exhaust ports have been optimised and the compression ratio modified. The entire combustion process has been retuned.
A correspondingly modified application of the accelerator characteristics, charge-pressure build-up and transmission parameters ensures that the engine responds to load changes even more spontaneously and that gear changes are effected with even greater speed. The fact that the two-mass flywheel is 0.7 kilograms lighter than its counterpart in the AMG GT S likewise contributes to the highly agile impression.

The Mercedes-AMG GT R was designed with racetrack use firmly in mind. Its development was largely based on vast motor-racing experience in AMG GT3 customer sport and the German Touring Car Masters. Figures such as 3.6 seconds from zero to 100 km/h and a top speed of 318 km/h.
