Prototypes of the Mercedes-Benz SLS AMG Black Series has been spied here and there, but we’ve finally caught some video of the hardest SLS AMG the street-legal world will soon get to know.

No specifications have been leaked yet, but it is speculated to have a 6.2-liter V8, uprated to something beyond 600 horsepower from its current 563 through engineering and not forced induction. Car and Driver predicts the Black Series will lose 100 pounds or so.
