The revised C63 gets new headlights and taillights with embedded LEDs. The front end gets a reworked grille and a new bumper and there are new alloy wheels. Under the hood Mercedes has decided to stick with the naturally aspirated 451-hp 6.2-liter V8 engine instead of the new 5.5-liter biturbo engine. The Development Package raises the engine’s output to 481 horsepower and allows the C63 to reach a top speed of 174 mph. The big change under the hood is that the seven-speed Speedshift MCT automatic transmission, ditches a conventional torque converter for a clutch pack. The transmission allows the driver to choose between four driving modes.
