The Mercedes-Benz SLS AMG Black Series is a track-oriented variant of the SLS AMG from the AMG division of Mercedes-Benz. The standout features of the SLS AMG Black Series include an upgraded engine which now produces 60 bhp more than the standard SLS V8 and has an 8,000 rpm redline, an aerodynamic package inspired by the SLS AMG GT3 race car, reduction in weight with extensive use of carbon-fibre and titanium parts, and an electronic limited-slip differential in place of a mechanical one found in the standard model.
