Mercedes SL65 AMG Black Series on the dyno

Mercedes isn't playing games with it's new SL65 AMG Black Series, especially with it's powerplant. The V12 is very potent on it's own, but a pair of turbos ensure that the Black Series is ridiculous enough to warrant it's high price tag.

Automobile decided to see just what kind of numbers they could pull with this shiny new Mercedes on the dyno. And it didn't disappoint, laying down 573 hp @ 5300 rpm and 682 lb-ft @ 3620 rpm at the rear wheels. The Black Series SL65 showed its superiority over the S65 AMG, as the more spartan AMG Benz put down 36 fewer ponies and 61 fewer lb-ft. At 5500 rpm, the Black Series' beefier turbos out-muscled the the S65 by 100 hp and 100 lb-ft.
