Here are the latest photos showing the Mercedes-Benz SLS AMG Black Series out doing some cold weather testing. If the regular SLS is not enough for you, AMG is working on a hard-core version to fulfill your racing dreams. If the 6.3-liter V8 with 563hp also doesn\'t impress you, then Mercedes engineers may have your best solution.With less weight, more power (around 650hp has been rumored) and an aggressive body kit this will be the hottest SLS built by the automaker so far. We can also see that the fenders are wider in order to fit those massive wheels. In addition, the front bumper has larger air intakes to feed the engine with loads of fresh air.So start saving your money because this monster will be out sometime next year.
