The Mercedes-Benz C63 AMG Black Series: it's got the special name, the special body kit, the special wing and the extra-special motor. But how special is its performance and handling? To find out, we took the latest Black Series Benz to the test track to generate performance numbers. Acceleration was tested with 0-60 and quarter-mile tests, while braking was calculated using 60-0. Handling tests included a timed slalom and two trips around a skid pad to generate a lateral acceleration calculation.
