You can consider the Mercedes-Benz C 450 AMG a bridge between a top-spec C-Class and the full berserk C 63 AMG performance model.
It comes with all the exclusive AMG exterior and interior appointments as well as the go-faster technology that comes with the badge. Mechanically, you get the AMG adaptive suspension, AMG-engineered exhaust system as well as the AMG Dynamic Select feature to control the suspension and power delivery. Speaking of which, the engine is the only thing setting the C 450 AMG apart from the C 63 AMG - a tuned 3-liter V6 mated to a 7G-TRONIC PLUS automatic gearbox.
