Updated Mercedes-Benz C63 AMG Leaks Ahead of Geneva Debut

Like the new C-Class Coupe, the updated Mercedes-Benz C63 AMG sports sedan wasn't supposed to appear before the Geneva Motor Show. But though the exposition is still over a month away, the car has found its way onto the internet.

Updated for the new model year, the C63 is distinguished by two major changes: one is the revised styling with new headlights, tail-lights and LED daytime running lights, new 18-unch wheels and upgrade brakes. Second is the new seven-speed multi-clutch transmission for smoother and faster shifts. It remains mated to the 6.2-liter V8 engine with its 451 horsepower (or 481 with the optional performance package).
