This is the most powerful Black Series car ever built. OK, so just two AMG Blacks were built before it, but weighing in at 670bhp and 737lb ft of torque, it is a genuine heavyweight.
Seconds out, round three...
AMG
 replaced the 6.0-litre V12's turbochargers with specially developed 
blowers incorporating a new spiral cross-section (12 per cent bigger), 
fitted a modified air intake duct and, of course, an AMG sports exhaust 
said to "produce a distinctive 12-cylinder sound" (read: LOUD). And 
while you're making that noise, it also covers ground in a dandy 
fashion: 0-62mph takes 3.9 seconds and it's limited (limited) to a top 
speed of 199mph.
The
 roof is made of CFRP with an integral rollover bar (binning the SL's 
drop-top), there's a CFRP spoiler, twin-spoke AMG 19in wheels and 390mm 
front discs (360mm rears). The engineers fitted adjustable coil spring 
suspension (allowing for driver adjustments) sitting on a track 97mm 
wider at the front and 85mm wider at the rear. They even fitted a 
limited slip diff as standard and a five-speed automatic gearbox with 
four transmission mode
