Mercedes Reportedly Preparing Even More Exclusive SLS AMG Black Series

With 617 horsepower and a 208mph top speed, topping the Mercedes SLR McLaren was no mean feat. Mercedes nearly managed to pull it off with the new SLS AMG. The gull-winged supercar was unveiled at the recent international auto show in Frankfurt to rave reviews. But it still falls a shade short of its predecessor's bragging rights, so the German automaker is reportedly working on an even more exclusive, more powerful and more capable SLS AMG Black Series.

Following in the Black Series that has given us the SLK55, CLK63 and SL65, the SLS Black is expected to gain some extra power and lose some weight to optimize that vital power to weight ratio. Sources expect the 563hp and 479lb-ft of torque from the existing 6.2-liter V8 to get a boost past the 600hp/500lb-ft mark, coupled with a 50kg weight-shaving scheme to drop the "stock" SLS' 0-62 mph time down from 3.8 seconds – already faster than 99% of the cars out on the road – to below 3.5 seconds, and the top speed up from 195 mph to 208.

Of course the added exclusivity won't come cheap: insiders expect the price to jump by half to over $250,000 when the SLS AMG Black Series hits the market in 2013.
