2019 Mercedes AMG C63 S Coupe

The proven AMG 4.0-litre V8 biturbo engine in this case puts out 350 kW (476 hp) or 375 kW (510 hp), while the maximum torque is 650 or 700 Nm. Depending on body style, the C 63 S accelerates from zero to 100 km/h in 3.9 seconds, the C 63 in 4.0 seconds. The top speed is up to 290 km/h for the C 63 S and 250 km/h for the C 63 (both electronically limited).

The 4.0-litre eight-cylinder biturbo engine is already used in numerous AMG Performance vehicles. A characteristic feature is that the two turbochargers are positioned not on the outside of the cylinder banks, but inside the cylinder "V". The main advantages of this design are the compact engine construction and optimal response.

The spray-guided direct petrol injection system ensures clean and efficient combustion with high thermodynamic efficiency. Fast-acting piezo injectors enable multiple injections of fuel to be delivered to the engine on demand and with the utmost precision.

The large cooling system guarantees the performance of the engine even under extreme loading ‑ such as at track days on the race track. The same is true for the flow-optimised cylinder heads, which are made of a special heat-resistant alloy. Continuous adjustment of the intake and exhaust camshafts improves power delivery and efficiency. It delivers excellent throttle response and optimises the charge cycle for every operating point. An oil pump with variable control also contributes to low fuel consumption.

One mechanic assembles each engine in the engine shop in Affalterbach according to the "one man ‑ one engine" principle.

The typical V8 engine sound is another key element of the AMG driving experience. The C 63 comes as standard with an AMG exhaust system with a variable flap. This is steplessly map-controlled depending on the drive program, the power demanded by the driver and the engine speed. The engine sound varies accordingly between discreet/suitable for long-distance driving, and robust/emotively appealing. A Performance exhaust system with three selectable exhaust flaps is optionally available for both engine variants. This gives the driver an even wider sound range. In any case, the exhaust systems are designed in such a way that all statutory noise limits are complied with at all times, irrespective of the flap position.
