This is the Mercedes-Benz SL 65 AMG Black Series.
MB describes it as the 'exclusive high-performance coupe for the discerning motorist'. By 'discerning' we presume they mean 'totally and utterly crazy in the heed'.
The SL Black - the third Black series car after the SLK and sensational CLK - is based on the latest SL 65.
The 6.0-litre V12 biturbo engine has been tweaked by AMG to 670bhp and 1000 Nm of torques - that's 737lb/ft in old money or 152lb/ft more than an SLR...
The standard SL 65 AMG has a measly 612bhp.
The SL Black also gets a chunky wide-arch bodykit, modified intake system, two trapezoidal tail pipes and a carbon roof. The SL's trick vario roof folding hardtop has been junked in favour of an integral roll cage. Composite brakes are fitted, as are 20-inch alloys and a retractable boot spoiler. The Black is 250kg lighter than the SL 65 AMG.
0-62mph comes up in 3.9 seconds and top speed is limited to 199mph - figures near identical to the SLR and all for £100,000 less than the big McMerc. Which begs the question, why spend the extra?
