For those who want more than just a standard SLS AMG, Mercedes->ke187 is about to unveil an even hotter version: the SLS AMG Black Series. After being caught testing around the Nurburgring, the car was recently taken out once again, this time for some tests during cold weather conditions.

Compared to a standard SLS, the Black Series will be lighter, deliver more power - rumored to be somewhere in the 650 HP area - and, of course, get an aggressive body kit. The spy shots reveal wider fenders and massive wheels, while the front bumper looks to have received bigger air intakes to push loads of fresh air into the rumored, revised 6.2 liter naturally aspirated V8 engine.

Tobias Moers, Member of the Board of Directors and Head of Vehicle Development for AMG, already confirmed that the company is hard at work on this model, so we should see it out sometime next year.
