It is being reported that Mercedes-Benz is developing a performance enhanced version of the SLS AMG – an SLS AMG Black Series to be exact. The car is expected to hit the market by 2013, and would be a totally different breed than the current SLS AMG.

Their plan is to increase the engine power and reduce the weight, which as you know is always a good way to increase performance of a vehicle. The current SLS AMG has 563 hp and 479 lb-ft of torque, now compare that with the expected 600 hp and 500 lb-ft of torque, which they’ll get by using a larger intake manifold, higher compression ration, high performance camshafts and others things.

AMG engine boss Friedrich Eichler was quoted as saying to Autocar: “We’re not at the limit with what’s out there the moment. There’s still a good deal more to come from the engine, we’re saving the best until last.”

The weight reduction will be about 50kg, so if we combine that with the increase in horsepower, we could expect a 0 to 62 mph in about 3.5 seconds, compared to the 3.8 seconds for the SLS AMG. The top speed would be raised from 208 mph, from the current 195mph. You can expect the price tag to be 40 to 50% more than the current SLS AMG, which if we take the announced $183,000 price tag for the SLS AMG, would mean that the Black Series would cost around $274,500.
