The Mercedes-AMG C63 Coupe is BMW M4’s newest “enemy”. The new sporty coupe from Stuttgart will make its world debut at the upcoming 2015 Franfurt Motor Show. Based on the sporty C-Class, the exterior design differs significantly from the standard model, which shares merely the same doors, roof and trunk lid. The flared wheel arches make the AMG Coupe 2.51-inches (64 mm) wider at the front and 2.59- inches (66 mm) wider at the rear.

The larger wheel arches allow the use of wider tires, up to 10 inches (255 millimeters) on the front axle and up to 11.2 inches (285 millimeters) on the rear.

The 2.36-inch (60 mm) longer aluminum hood is adorned by two distinctive powerdomes, which are among the typical distinguishing features and underscore the muscular appearance. The extremely wide front section is characterized by large air inlets and precisely positioned aero flics. The low, arrow-shaped “twin blade” grill with AMG lettering visually lowers the vehicle’s center of gravity. The typical AMG “A-wing” front spoiler is three-dimensional, also serving as an air deflector for the three cooling air inlets. Additional aero flics ensure an optimal flow of air to the cooling modules, while a front splitter at the bottom of the front apron helps reduce front-axle lift.

Inside, as an alternative to the standard sports seats in ARTICO/microfiber DINAMICA, performance seats are also available, which offer occupants a lower seating position and more aggressively contoured bolsters for increased lateral support.

Like the AMG versions of the C-Class sedan and station wagon, the new Mercedes-AMG C 63 Coupe is powered by a twin-turbo V8 with 4.0 liter displacement. The base engine delivers 476 hp eight-cylinder, already around 10 percent more powerful than the 425 hp six-cylinder in the BMW M4. The AMG C63 S delivers 510-hp version from the same engine. The base C63 features has 479 lb-ft of torque while the C63 S comes with 516 lb-ft.

The C63 S Coupe accelerates from 0 to 60 mph in 3.8 seconds, and the C63 Coupe in 3.9 seconds. This makes the Coupe just a fraction faster than the Sedan – thanks to the wider tires and shorter- legged rear-axle ratios. The top speed is electronically limited to 155 mph on the C63 Coupe, and 180 mph on the C63 S Coupe. Both variants send the power to the wheels via the Speedshift seven-speed automatic transmission.

A tradition here at BMWBLOG is to compare BMW cars with similar vehicles in its segment, so we put together a visual comparison between the M4 Coupe and the new AMG C63.
