The facelifted 2012 Mercedes-Benz C63 AMG wasn't supposed to see the light of day until the Geneva Motor Show this March, but a sizable batch of photos have leaked out giving us a clear look at what to expect in Switzerland.
On the outside, the C63 gets a set of SL-inspired headlamps with ornate light-piping and LED DRLs mounted in the revised fascia. LEDs make their way to the tail lamps, while redesigned 18-inch wheels fill the wheel wells and frame upgraded brakes.
AMG opted to retain the 6.2-liter V8 instead of fitting its new 5.5-liter biturbo mill, so output remains at 451 horsepower and 443 pound-feet of torque. The Development Package will reportedly stick around for 2012, raising output to 481 hp and nixing the 155 mph limiter to allow the C63 to top out at 174 mph. The sports package also includes a few interior tweaks, a carbon fiber trunk spoiler and red calipers that clamp onto 14.2-inch front discs.
However, the biggest change comes in the form of a new transmission. The C63 now sends power to a seven-speed Speedshift MCT auto 'box which swaps out the conventional torque converter for a high-performance clutch pack said to deliver smoother, more immediate shifts.
After the C63's big day in Geneva, the revised C-Class will go on sale this fall, with the AMG-fettled version getting a very slight bump in price.
