First AMG out-AMG'd itself with the CLK63 Black Series. Next up is a car likely to make you forget that Mercedes-McLaren SLR, the SL65 AMG Black Series. Power from the SL65 AMG's twin-turbo 6.0-liter V-12 will be increased well past that car's 604 horsepower, and significantly past 650 horses, while maintaining the 738 pound-feet (1,000 KW) of the "quotidian" SL65 AMG. The SL Black Series gets new, mostly carbon-fiber bodywork and a fixed roof, which helps cut bodyweight. The Black Series is expected to shed more than 500 pounds versus the SL65. Only the rear quarter-panels remain rendered in steel. The SL's new grille is more squat on the Black Series, and the hood is apparently exempt from new European pedestrian safety laws, thanks to very low volume production. The SL65 Black Series is scheduled to make its debut at the German Grand Prix in July.
