Spotted wearing minimal camouflage, the C55 features an aggressive design and a new engine.

Our spies have managed to catch several new images of the 2012 Mercedes C55 AMG Coupe.

Spotted wearing minimal camouflage, the coupe appears to have a front end that is virtually identical to the sedan variant which leaked late last month.  Further back, the car's profile is similar to the standard C-Class coupe but there's modified side sills, a larger rear spoiler, a four-tailpipe exhaust system, and AMG wheels which cover a high-performance braking system with cross-drilled brake discs.

Unlike the sedan and estate, which use a 6.3-liter (6208cc) V8 with 451 hp (336 kW / 457 PS) and 443 lb-ft (600 Nm) of torque, the coupe is slated to feature a naturally-aspirated version of the twin-turbo 5.5-liter V8 from the S63 AMG and CLS63 AMG. Details are limited, but the engine is expected to produce 422 hp (315 kW / 428 PS) and have multi-cylinder deactivation for improved fuel efficiency.

No word on when the car will be unveiled, but the standard model is scheduled to debut at the Geneva Motor Show.
