U.S.-based German tuner RENNtech celebrated Black Friday this year the only way they know how, with a Black Series Mercedes. The occasion was the perfect opportunity for them to remind us of the RENNtech Mercedes SLS Black Series and what they can do to improve the super car.  RENNtech Mercedes SLS Black Series

RENNtech Mercedes SLS Black Series is the next logical step if you already own a normal RENNtech SLS, unless you want to get the RENNtech AMG GT which is equally awesome.

But in case you want to go Black, this bad boy features an ECU upgrade and stainless steel long tube headers for a total of 613 horsepower and 515 Nm of torque. If you are wondering what that exhaust system sounds like? Well, as we have mentioned before, it’s deafening!

The big dog RENNtech Mercedes SLS Black Series also features a carbon fiber body kit consisting of an extended front spoiler lip, side skirt, rear tail spoiler and rear diffuser. The kit, as is often the case with RENNtech products, looks pretty discreet and understated, although the car itself is anything but, what with those massive arches and the gullwing doors.
