The Black Series vehicles have always been the ultimate in what AMG can do with a Mercedes-Benz model. In the case of the C63 AMG Black Series, we suspect that it will get more power, lose a bit of weight and come with more performance parts.

The 6.2-litre V8 develops 336kW in its current form but rumours suggest the Black Series will push around 380kW through its AMG 7 speed gearbox. That will surely get its 0-100km/h time as close to 4.0 seconds as possible.

Apart from the wider fenders, the front spoiler is also likely to be larger and the rear diffuser might feature some Formula 1 inspired looks.

The Black Series is also sure to get bigger brakes with ceramic discs and other performance upgrades. It's likely that the Mercedes-Benz C 63 AMG Black Series saloon will be followed by a Coupe variant later on.
