Currently the BMW M4 GTS is the Bavarian benchmark when it comes to street and track performance and by the looks of things, Mercedes-AMG are coming at them with a seriously hardcore version of it’s C63 Coupe. Looking at the spy shots I would lean away from this being the C63 Coupe Black Series replacement but rather a track-focused model dubbed the C63 R Coupe. Whatever it is called, it will look wild thanks to a more aggressive front bumper and that not so subtle rear wing. If it is the R version of the C63, we can expect a power increase to something around the region of the GT R which is 577 horses but I would assume a power output of around 550 horses is a safe bet. What do you all think?
