Dynamics plus long-distance comfort -the Mercedes-AMG C63 sedan offers impressive engine output with exceptionally low fuel consumption figures, outstanding longitudinal and lateral dynamics and yet delivers a high level of everyday usability. As form is just as important as function, the interior and exterior design is more distinctive than ever before.
The V8 pinnacle in the C-Class portfoilio is available in a choice of two models -the Mercedes-AMG C63 and C63 S, with the C63 S set up for even more dynamic handling and performance.
This impressive efficiency improvement is rooted in the new drive package. The M177 4.0-litre V8 biturbo engine, the newest member of the BlueDIRECT engine family, is a close relative of the M178, which is the sports-car heart of the new Mercedes-AMG GT. The innovative eight-cylinder is notable for its outstanding power delivery, targeted lightweight design, high efficiency and environmental compatibility. It also fulfils the highest standards in terms of noise and vibration comfort.
The newly developed eight-cylinder features biturbocharging, whereby the two chargers are not located on the outside of the cylinder banks, but instead, within the cylinder V - specialists refer to this as the “hot inside V”. The benefits are compact engine dimensions, optimum responsiveness and low exhaust emissions.
Mixture preparation is handled by the petrol piezo direct injection system used exclusively by Mercedes. The third generation of the spray-guided combustion process has been developed to meet all future legislative requirements. The highly efficient and clean 4.0-litre V8 biturbo engine fulfils the Euro 6 emissions standard, including the rules pertaining to maximum particulate emissions that do not come into effect until 2016. A sophisticated engine cooling system ensures high performance even at ambitious race-track speeds.
A further new feature of the C 63 S that is unique in the competitive field is the dynamic engine mounts - as used on the Mercedes-AMG GT. They address the conflict of interest between comfort and handling by reducing vibration from the engine/transmission unit. The dynamic mounts can adapt their stiffness smoothly and in fractions of a second to the prevailing driving conditions and style. Soft engine mounts improve comfort by better decoupling noise and vibration. Handling and agility, on the other hand, benefit from slightly stiffer mounts. When driving dynamically, the driver feels more closely connected to the vehicle as a result of increased feedback, while steering response is more direct. The driver benefits overall from a more precise driving feel. Minimized movement of the drivetrain mass calls for less correction on turn-in.
Powerful V8 engines have always been one of the competencies of AMG, the Mercedes-Benz performance brand. Mercedes-AMG GmbH is fully responsible for development and production. The 4.0-litre V8 biturbo engine is manufactured in the Affalterbach engine shop in accordance with the “one man, one engine” principle.
