Official: Mercedes SLS AMG Black Series

The new Mercedes-Benz SLS AMG Black Series has been revealed ahead of going on sale in the Summer of 2013. The SLS Black Series gets the usual mix for a Mercedes Black Series model – more power and less weight – and uses the same 6.2 litre V8 as the regular SLS but with the wick turned up to 622 horses from the regular, but hardly wanting, 583 thanks to a new air intake, cams, boost tweaks and better cooling. The oily tweaks for more power – and some weight shedding (70kg) – means the SLS Black can get to 62mph in 3.6 seconds – 0.2 seconds quicker than the regular SLS – and top out at 196mph (due to the extra downforce).
