The all-new Mercedez-AMG C 63 Coupe is set to make its worldwide debut on September 15 at the International Motor Show in Frankfurt. On the heels of the Mercedes-Benz C-Class Coupe, the AMG version represents a significant stride toward visual autonomy and technical design for the German marque. The forthcoming car is being touted by AMG as a new plateau of driving performance, thanks to a 4.0-liter V8 biturbo engine in 476 hp or 510 hp variants, the result of a complete in-house development from AMG. On the exterior, the car benefits from nicely balanced expression of proportions - specifically several tweaks on the standard Mercedes-Benz version - including wider front and rear axles, flared fenders, and redesigned front end.
