Mercedes SL-Class Black Series

Mercedes will add a new model to the Black Series line-up in July. The upcoming SL65 AMG Black Series is based on the SL65 AMG and will follow the route taken by the SLK55 AMG and CLK63 Black Series models.

The SL65 AMG Black Series will be powered by a reworked version of the SL65 AMG’s twin-turbocharged 6.0-liter V12 engine, tuned to deliver in the vicinity of 680 hp.

"We could have easily got 720 hp without any significant modifications. In the end, though, we decided to dial it back," said an insider privy to the new car’s development. "There will be a slight increase in power, but really it’s all about creating optimal conditions for the introduction of direct injection," a source said.
