Mercedes-Benz has a history of offering performance models that would make any niche super car manufacturer cower. The latest among them is the SLS AMG, but the gull wing coupe and its roadster counterpart aren't the extent of what the German automaker's skunk works have in store. No, that place of honor at the top of the Mercedes-Benz lineup will soon be taken by an SLS AMG Black Series.
Following in the footsteps of the SLK55 AMG Black Series, CLK63 AMG Black Series, SL65 AMG Black Series and the C63 AMG Black Series, the new SLS AMG Black Series promises to eclipse them all with an anticipated 560 horsepower, reduced curb weight and aggressive aerodynamics package.
These spy shots, snapped while the vehicle was undergoing cold-weather testing in the frigid north, also show the tell-tale widened fenders to house the upgraded rolling stock and a new front bumper to feed the over-clocked engine with all the air it needs to breathe.
We're told to expect the SLS AMG Black Series sometime next year
