The most extreme version of the Mercedes C63 AMG - the Coupe Black Series - takes a trip to the racetrack. The C63 Black is one of the most insane rides available on the market today. With an electronically limited top speed of 186 mph and a 0-62 mph acceleration of just 4.2 seconds, the C63 AMG Black is a serious tool for both the circuit and the public roads. In comparison, the SLS AMG supercar makes the trip from nought to 62 mph in 4.1 seconds.
