The new Mercedes-AMG EQS 53 4MATIC+ goes official at IAA Mobility 2021With the new Mercedes-AMG EQS 53 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 EQS 53 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.

In this case, the new Mercedes-AMG EQS 53 4MATIC+ accelerates from 0-100 km/h in 3.4 seconds with a battery charge level of at least 80 percent. The top speed is limited to 250 km/h with the optional package. In the basic version the AMG EQS accelerates from 0-100 km/h in 3.8 seconds (minimum 80% battery charge). Its maximum speed is limited to 220 km/h.

Mercedes-AMG models have always stood for emotionality. The vehicle sound has always been an important part of the hallmark AMG driving experience. This will continue to be the case in the future. The EQS 53 4MATIC+ brings a new, powerfully sonorous sound to electric driving. Its sound system uses special loudspeakers, shakers and a sound generator to create a special sound experience in two versions: "Authentic" or "Performance". This exclusive AMG SOUND EXPERIENCE is generated inside and out with a tonality and intensity to match the current driving status, the selected driving mode or the driver's wishes.

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 electric motor at the rear axle of the EQS 53 4MATIC+ is particularly powerful. A major reason for this is the six-phase design based on two windings with three phases each. The stators with move-in winding ensure a particularly powerful magnetic field.

The new Mercedes-AMG EQS 53 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. In the Sport and Sport+ driving modes the focus is on performance, in Comfort mode on operating range. The new generation of batteries is characterised by a significantly higher energy density compared to previous developments. It also has a higher charging capacity. Another new feature is the possibility to install updates for the battery management system over the air. The battery can be charged with up to 200 kW at quick-charging stations with direct current. Thanks to the onboard charger, the electrified AMG can be conveniently charged at home or at public charging stations with up to 22 kW of alternating current. In Japan, bidirectional charging will also be possible, i.e. charging in both directions. The battery design aims to ensure the optimum battery operating temperature under all operating conditions. The battery certificate stands for the long service life of the high-voltage batteries. It is valid up to a term of ten years or up to 250,000 kilometres.

The power of the battery-powered motors is brought to the road by the standard AMG Performance 4MATIC+ fully variable all-wheel drive system. The system continuously distributes the drive torques between the front and rear axles, depending on the driving situation. The suspension of the new Mercedes-AMG EQS 53 4MATIC+ features a four‑link axle at the front and a multi-link axle at the rear. AMG engineers have specifically improved the components and configured them to meet the special requirements of AMG customers. This applies to ride comfort as well as driving dynamics. The AMG RIDE CONTROL+ suspension is an air suspension system combined with adaptive, electronically controlled adjustable damping together with rear-axle steering as standard.

The suspension components that have an influence on the driving dynamics are new and AMG-specific. This applies to the rear axle beam, for example, which the engineers in Affalterbach have completely redeveloped. The subframe and motor mountings are also completely new developments, and exclusive to the AMG models. This also applies e.g. to the revised transverse stabilisers, as well as the wheel carriers and control arms, which are derived from other AMG Performance models. The standard air suspension of the EQS 53 4MATIC+ uses two pressure relief valves. The suspension control unit analyses data - including data from the acceleration and wheel path sensors - to adjust the damping force for each wheel in a few milliseconds to suit the situation.

The Mercedes-AMG EQS 53 4MATIC+ is equipped with rear-axle steering as standard. The interaction between front-axle and rear-axle steering is designed to achieve agile responses with little steering effort when driving in town or on country roads. At speeds below 60 km/h, the rear wheels steer in the opposite direction to the front wheels. This makes the AMG EQS highly manoeuvrable, light-footed and nimble. The effect is particularly positive when turning off, changing direction quickly and manoeuvring slowly. From a speed of more than 60 km/h, the rear wheels steer in the same direction as the front wheels. The resulting virtually extended wheelbase offers increased handling stability and driving safety at high speeds, and during fast lane changes or sudden evasive manoeuvres.

The driving characteristics of the Mercedes-AMG EQS 53 4MATIC+ can be altered by the driver at the touch of a button, to suit the situation or personal preferences. This is made possible by the five AMG DYNAMIC SELECT driving modes "Slippery", "Comfort", "Sport", "Sport+" and "Individual".

The Mercedes-AMG EQS 53 4MATIC+ is equipped with the innovative MBUX Hyperscreen as standard. This large, curved screen unit extends from A-pillar to A-pillar. Three screens sit under a glass cover and appear to merge into one. With adaptive software, MBUX adapts completely to its user and offers personalised suggestions for numerous infotainment, comfort and vehicle functions. With what is known as the zero layer, the most important applications are always displayed situationally and contextually on the top level in the field of vision. In Europe and China, dynamic content is also permitted on the passenger display while driving. Unrestricted viewing of films, text messages or presentations, pus internet surfing, are therefore possible. This is made possible by the so-called "blanking function", which prevents the driver from seeing the content.

The AMG DYNAMIC PLUS package, available as an option, combines dynamic driving extras - including the powerful boost for RACE START and the increase in maximum speed to 250 km/h - with the emotional AMG sound experience "Performance". The latter provides a distinctive sound experience in the three selectable levels "Balanced", "Sport" and "Powerful". The intensity of the acoustic setup depends on the current driving status and the selected driving mode. Sounds composed especially for the Performance sound world - for charging or infotainment functions, for example - round off the AMG experience.
