Mercedes Benz

Mercedes-AMG is readying the anticipated C 63 AMG Black Series hardcore models (Limousine and Coupe) for an official debut slanted for the Frankurt Auto Show in September. Tweaking session include German streets and lately, the famous Nurburgring track, where a Coupe prototype was recently scooped. Engineers from Affalterbach have fitted the new uber-sports versions with a grumpy V8 engine - there's still a lot of uncertainty whether the chosen one will be the new twin-turbo or the already outgoing aspirated unit. In any case, hints indicate the performance figures will somehow match those of the discontinued CLK 63 AMG Black Series, meaning 507 hp as peak output. Boundaries of ultimate dynamics are to be pushed to the highest-ever limits, as any part from the front air intakes to the rear diffuser and exhausts going through the brakes, suspension, dampers, chassis, the upgraded architecture and the intricate technology were specially re-developed for top on-road behaviour.
