Not that the recently updated Mercedes-Benz SL65 AMG with its 612HP twin-turbocharged V12 engine isn’t powerful or fast enough, but you’ll always have a few customers -very few to be honest- that crave for something a bit more special, a bit more fast and a whole lot more expensive. The result was the introduction of the SL 65 AMG ‘Black Series’ of which only 350 will be produced, with around 200 of those earmarked for the U.S. As a typical example of Merc’s ‘Black Series’ cars, this SL has been stripped out and tuned to the bone. Among other upgrades the ‘Black Series’ has been enhanced with a fixed carbon-fiber rooftop and a tweaked 6.0-liter twin-turbo V12 engine producing 670HP and a monstrous 738 lbs/ft of torque.
