With a more striking design, enhanced options for individualisation and the MBUX infotainment system, Mercedes-AMG is enhancing the E53 4MATIC+ Saloon and Estate business-class models. The completely restyled front view lends the Performance E-Class an even more powerful appearance. The AMG-specific radiator grille with its A-shaped contour reinforces the impression of width, as do the flat LED headlamps.
Extensive design measures also make the rear view of the saloon look even more muscular. They include the two-piece tail lights, the new rear apron and the new diffuser insert. The interior is also characterised by more sportiness in the form of large displays, the new AMG Performance steering wheel and the AMG-specific MBUX functions. The electrified 3.0-litre engine with twin turbocharging via an exhaust gas turbocharger and an electric additional compressor generates an output of 320 kW (435 hp) and produces a peak torque of 520 Nm. Its EQ Boost starter-alternator briefly provides an additional 16 kW of output plus 250 Nm of torque and also feeds the 48 V on-board electrical system. Other technical highlights include the AMG SPEEDSHIFT TCT 9G transmission and the fully variable all-wheel drive system AMG Performance 4MATIC+.
Six-cylinder in-line engine with EQ Boost starter-alternator
The 3.0-litre six-cylinder in-line engine of the E53 models is characterised by top performance and intelligent electrification. The EQ Boost starter-alternator combines a starter motor and alternator in a powerful electric motor and is fitted between the engine and transmission. It is not only used as an electric alternator, but also performs hybrid functions. These include boost with 16 kW of output and 250 Nm of torque, recuperation, shifting of the load point, gliding mode and the virtually imperceptible restarting of the engine with the start/stop function.
This innovation as well as the intelligent charging via an electric additional compressor and an exhaust gas turbocharger all have the same goal: to enhance the hallmark AMG performance and driving dynamics, while at the same time reducing fuel consumption and emissions. The starter-alternator provides support with its boost when moving off, plus the electric additional compressor builds up a high charge pressure without any delay, for a faster increase in torque for acceleration until the large exhaust gas turbocharger is deployed. As a result the 3.0-litre engine reacts extremely spontaneously, and provides a highly dynamic response without what is known as turbo lag. An additional bonus is the high level of refinement of the six-cylinder in-line engine.
