The AMG 6.3-liter V8 engine in the Mercedes-Benz C63 AMG Coupe delivers a maximum output of 451 hp and peak torque of 443 lb-ft. Reflecting its outstanding performance, the coupe is capable of accelerating from 0 to 60 mph in 4.4 seconds with a top speed of 155 mph (electronically limited).

The new coupe shares all the technology updates from the 2012 Mercedes-Benz C63 AMG Sedan and features the AMG SPEEDSHIFT MCT 7-speed sports transmission with standard “Controlled Efficiency” mode, and a new power steering pump that helps to reduce fuel consumption.

This reduction in fuel consumption also applies to the Mercedes-Benz C63 Coupe when equipped with the AMG Development Package which generates 481 hp. This optional package improves acceleration from 0 to 60 mph to 4.3 seconds thanks to technology transferred from the SLS AMG. The forged pistons, connectin grods and lightweight crankshaft adopted from the gullwing model’s high-tech drive system save 6.6 pounds in weight. Top speed increases as well to 174 mph (electronically limited).

The AMG SPEEDSHIFT MCT 7-speed transmission on the C63 Coupe features a compact, wet start-up clutch which reduces the power losses normally associated with conventional automatic transmissions and significantly lowers fuel consumption. The Controlled Efficiency “C” mode provides early, comfortable upshifts while maintaining the lowest possible engine speed and “soft” accelerator characteristics to help improve fuel economy.

It’s not just the engine and MCT transmission which influence the Mercedes-Benz C63 AMG Coupe’s aggressive character – the AMG sports suspension and AMG high-performance braking system are also key here. Compared with the standard suspension, the AMG coupe has a separate three-link front suspension, a reinforced multi-link independent rear suspension and a wider track front and rear.

The AMG speed-sensitive sports steering with a direct ratio (13.5: 1) provides excellent road feel and contributes to the nimble driving experience. The precise steering is complemented by three-stage ESP¨, the Electronic Stability Program that enables three individual control strategies to be accessed at the touch of a button. The driver can use the ESP¨ switch on the center console to choose between ESP ON, ESP SPORT and ESP OFF modes.

With nine airbags as standard, belt tensioners and belt-force limiters for all seats, the new Mercedes-Benz C63 AMG Coupe has extensive safety features. The airbags, which can deploy in milliseconds in the event of an accident, include front, side and pelvic bags for the driver and front passenger, a kneebag on the driver’s side, and windowbags.

The new Mercedes-Benz C63 AMG Coupe will make its U.S. showroom debut in September 2011.
