This isn't the first time they are showing us a mystery AMG model hiding under a sheet, however, this time it's not much of a mystery. We've been looking at the spy photos and videos for the past year, and finally the SL 65 AMG Black Series is ready to debut next month at the Formula One German Grand Prix.
Transformation towards Black Series will see a boost in performance of the 6.0-liter twin-turbo V12 up to 680hp – that's 76hp more than the standard SL 65 AMG Roadster and 30hp more than the Mercedes-McLaren SLR 722. According to Autoweek, an insider close to the development stated that engineers could have easily extracted 720hp out of this engine without any major modifications but decided to cap it.
Capable of 220 mph but electronically limited to 186 mph (300 km/h), 0-60 mph should arrives in less than 4.0 seconds.
Only 350 units will be sold worldwide with deliveries commencing in 2009.
