The AMG 4.0-litre V8 biturbo engine in the 2021 Mercedes E63 S AMG 4MATIC+ continues to achieve 612 horsepower (450 kW) and a maximum torque of 850 Nm. It’s 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 E 63 4MATIC+ base model has an output of 571 horsepower (420kW) and 750 Nm torque. The S version of the Saloon completes the sprint from 0 to 100 km/h (62 mph) 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-liter 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 4 or 8-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.
The S version is the only car in its competitive segment that is fitted with dynamic engine mounts. They solve the conflicting goals of achieving as soft a connection as possible to the powertrain for high comfort and as rigid a connection as possible for optimum driving dynamics. The dynamic mounts are quickly and variably able to adapt their stiffness to the driving conditions and requirements. These measures enhance the vehicle’s precision when driven dynamically, while the soft setting increases comfort tangibly.
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.
All E63 variants are equipped with the AMG Performance 4MATIC+ all-wheel drive as standard. This intelligent system combines the advantages of different drive concepts: torque distribution on the front and rear axles, which is fully variable for the first time, ensures optimum traction on any surface. The driver can rely on a high level of handling safety. An electromechanically controlled clutch connects the permanently driven rear axle variably to the front axle. The best possible torque distribution is calculated continuously. The performance model can thus be driven in a continuously variable way from traction-oriented all-wheel drive to purely rear-wheel drive. In addition to traction and lateral dynamics, the all-wheel-drive system also improves the longitudinal dynamics for even more powerful acceleration.
It’s still possible to drift thanks to fully variable torque distribution. The Drift Mode integrated into the S-Models as standard is ideal for this. This can be activated in the «RACE» drive program using the shift paddles, provided that ESP is deactivated and the transmission is in manual mode. When Drift Mode is activated, the E 63 S 4MATIC+ becomes a purely rear-wheel drive vehicle. Drift Mode remains engaged until the driver deactivates it again.
Direct and with clear feedback: the AMG speed-sensitive steering:
The electromechanical speed-sensitive power steering has a variable ratio and impresses with its precise, authentic feedback. The steering servo assistance is reduced at high speeds, and continuously increases at lower speeds. This means that comparatively little steering force is required at low speeds, while the best possible control over the vehicle is maintained at high speeds. The steering assistance is assigned to the various stages of the AMG DYNAMICS system. Comfortable steering tuning is set in «Basic». In «Advanced» and «Master/Pro», the driver receives incrementally more feedback about the driving status thanks to sportier steering tuning.
