With the new EQS53 4MATIC+ Mercedes-AMG is embarking on the all-electric future of Driving Performance. The first battery-electric AMG production model is based on the Mercedes EQ architecture for luxury and executive-class vehicles. It thus fits seamlessly into the Group-wide electric strategy. The luxury saloon with an output of up to 560 kW has been newly developed or refined in Affalterbach in all performance-related areas. It impresses with brand-specific features wherever the customer can experience them directly: from the technology to the exterior/interior design and the emotive vehicle sound.
At the heart of the new Mercedes-AMG EQS53 4MATIC+ is its performance-oriented drive concept with two motors. The powerful electric powertrain with one motor each at the front and rear axles has fully-variable AMG Performance 4MATIC+ all-wheel drive, which optimally transmits the drive power to the asphalt in all driving conditions. The basic version achieves a maximum total output of 484 kW (658 hp), with a maximum motor torque of 950 Nm. With the AMG DYNAMIC PLUS package, which is available as an option, the maximum output increases to up to 560 kW (761 hp) in RACE START mode with boost function. The maximum motor torque is then up to 1020 Nm.
The AMG-specific electric motors at the front and rear axles are permanently excited synchronous motors (PSM). The decided emphasis on performance is already evident in the output and torque values. In addition, the Mercedes-AMG electric motors are characterised by an optimum balance of enhanced power, efficiency and noise comfort. Among other things, this is ensured by new windings, stronger currents and new actuation via inverters with specially developed software. This allows higher rotational speeds and thus more power, setting standards especially in acceleration and top speed.
The new Mercedes-AMG EQS53 4MATIC+ is equipped with a powerful 400-volt battery manufactured using the latest lithium-ion technology. A major advance in sustainability has been achieved in the cell chemistry: the cobalt content is reduced to ten percent, the optimised active material consists of nickel, cobalt and manganese in a ratio of 8:1:1. The high-voltage battery has a usable energy content of 107.8 kWh. One special technical feature is the AMG-specific wiring, which is adapted to the high performance capacity. The battery management system is also configured specifically for AMG.
The battery sits in a crash-protected area in the underbody, embedded in the body shell structure including an extruded aluminium profile on the side. During extrusion, a heated block of metal is pushed through the dies and turns into an endless section, which is then cut to fit. This makes highly complex sections that are precisely tailored to the requirements possible. The housing with energy-absorbing structures at the front and side as well as a rigid, double-walled base plate provide additional protection for the modules. Extensive crash and component tests have been part of the standard procedure at Mercedes-Benz for decades, and the standard is acknowledged to be high – the internal requirements are often significantly more stringent than the law requires.
