The upcoming SLS AMG Black Series was officially confirmed to deliver at least 50 HP over the standard SLS AMG->ke2504, possibly with revised 6.2 liter naturally aspirated V8 engine as the power source. That means a final output of 633 HP when compared to the 583 HP in the new GT Version. With the extra power, the Black Series will most likely go from 0 to 60 mph in less than 3.5 seconds.
