The new look of the Mercedes-AMG E63 4MATIC+ models, which catches the eye at first glance, is also down to technical reasons to a large extent. In order to ensure optimum air throughput around the 4.0-litre V8 biturbo engine including charge air cooling, the outer air intakes in the jet-wing are not only particularly large; they also guide the air to where it is required in a targeted manner with the aid of two transverse louvres.
AMG 4.0 litre V8 biturbo engine with twin-scroll turbochargers
The AMG 4.0-litre V8 biturbo engine in the E63 S 4MATIC+ continues to achieve 450 kW (612 hp) and a maximum torque of 850 Nm. It is available across a wide engine speed range from 2500 to 4500 rpm, thus conveying the feeling of effortless superiority with every accelerator pedal position. The E63 4MATIC+ base model has an output of 420 kW (571 hp) and 750 Nm torque. The S version of the Saloon completes the sprint from 0 to 100 km/h in 3.4 seconds and in 3.5 seconds as the base variant. The values for the Estate are 3.5 seconds (S version) and 3.6 seconds (base variant), respectively.
In order to ensure optimum output and response from the AMG 4.0-litre V8 engine, the two exhaust gas turbochargers feature twin-scroll technology. They reduce the exhaust gas back-pressure and optimise the gas cycle. Thanks to the standard cylinder shutoff and further measures the performance models are highly efficient. When the driver has selected the "Comfort" drive program, the cylinder deactivation system is available in a wide engine speed range from 1000 to 3250 rpm. A special display in the instrument cluster indicates whether the cylinder deactivation system is in use and whether the engine is presently operating in four or eight-cylinder mode. The transition between these two operating states is immediate, fast and torque-neutral, so the occupants do not have to relinquish any comfort.
Short shift times, high efficiency: the AMG SPEEDSHIFT MCT 9-speed transmission
The AMG SPEEDSHIFT MCT 9-speed transmission is specially tuned to the requirements of the performance models. The autonomous software enables extremely short shift times and fast multiple downshifts while the double-clutching function makes for an emotive gearshifting experience. A wet multi-plate start-off clutch replaces the torque converter. It saves weight and optimises response, especially when accelerating or coming off the power.
