A prototype for the Mercedes SL Black Series has been spotted on public roads around the Nürburgring, in preparation for some hot laps later this week. This is the most wicked SL ever conceived, with optimum performance its top priority.
Huge flared fenders are likely created with ultra-light carbon fibre, to reduce weight and to accommodate this car's enormous wheels and tires. The roof on this SL has been converted into a fixed coupe roof, also crafted in carbon fibre to lower the Black Series' center of gravity and further reduce weight. Exactly what engine mods have been employed here are uncertain, but you can be sure it's insanely powerful.
Our spies will be hot on the tail of the SL Black Series, so keep an eye out for more pics from the Ring.
