The 4.0-litre 8-cylinder biturbo engine is already used in the C 63 Saloon and the C 63 Estate. It is also installed in the GT sports car with dry sump lubrication. Characteristic feature: the two turbochargers are positioned not on the outside of the cylinder banks, but between them in the "V" – experts call this a "hot inside V". The main advantages of this design are the compact engine construction, optimal response and low exhaust gas emissions.
Exhaust system with flap technology for variable engine sound
The typical V8 engine sound was likewise a key development goal. It was specially tailored to the Coupé. A model-specific exhaust system with flap technology is used as standard.
It is automatically map-controlled depending on the AMG DYNAMIC SELECT transmission mode, the power demanded by the driver and the engine speed. The engine sound varies between discreet/suitable for long-distance driving and robust/emotively appealing. Optionally available is the Performance exhaust system, which allows the sound to be modulated at the press of a button. In any case, the exhaust systems are so designed that all noise limits are at all times complied with irrespective of the flap position.
Faster gearshifts: the AMG SPEEDSHIFT MCT 7-speed sports transmission
The transmission plays a major part in the direct and sporty character of the new Mercedes-AMG C 63 Coupé. The AMG SPEEDSHIFT MCT 7-speed sports transmission impresses with its tailor-made dynamics and high variability. Whether automatic or initiated by the driver using the steering wheel shift paddles, upshifts and downshifts are executed noticeably faster than in the previous model. This increased spontaneity is made possible by an even sportier set-up of the engine and transmission parameters.
