When the Mercedes-AMG C63 Coupe hits showrooms in 2015, it will line up squarely against the BMW M4, Lexus RC F and the Audi RS 5. Rendering artist X-Tomi has manipulated the recent pictures of the C63 S Sedan, creating a sleeker profile and nixing the back doors. The S model delivers 503 hp and 516 lb-ft of torque, which translates to an electronically-limited top speed of 155 mph, a 0-62 mph time of 4.0 seconds in the sedan and 4.1 in the wagon. All variants are mated to AMG's seven-speed Speedshift MCT automatic with paddle shifters.
