For the Black Series upgrade, Mercedes has revved the 6.3-liter V-8 to ever-higher speeds, pushing total power to 631 hp, a 68-hp bump over the plain SLS AMG. Combined with revised 7-speed automatic transmission, lighter wheels, revised suspension and other tricks allows the Black Series SLS to hit 60 mph in 3.8 seconds.
How trick? Instead of traditional engine mounts, the SLS AMG Black uses a gas-mounted strut to keep the engine from shifting under massive g-forces. Instead of traditional steel exhaust pipes, AMG engineers crafted the Black Series' tubes from titanium. Even the rear differential switches from a traditional mechanical limited-slip to electric -- in the name of saving weight and better performance.
They even deleted the info-disco dash system to save 13 lbs. -- although buyers who can't do without their Nicki Minaj tunes can add it back as an option.
