With the new EQS 53 4MATIC+ (combined WLTP power consumption: 23.4-21.1 kWh/100 km; CO2 emissions combined, WLTP: 0 g/km; electric range, WLTP: 529-586 km)[1] 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.
“The AMG EQS 53 4MATIC+ is the first all-electric ambassador in the performance segment, made in Affalterbach. It is tailor-made for car enthusiasts who are looking for a combination of innovative electric mobility in a luxurious ambience, coupled with sportiness and agile driving dynamics. With our first all-electric AMG vehicle, we will undoubtedly appeal to and win over a new clientele for Mercedes-AMG. In addition, the EQS 53 is further proof that Mercedes-Benz is consistently driving electrification forward with all its brands as well. Further all-electric AMG models will follow in the not too distant future, also on our AMG.EA platform developed entirely in-house,” says Philipp Schiemer, Chairman of the Board of Management of Mercedes‑AMG GmbH.
“Also with electrification, we ensure that our models based on the EVA2 group platform will deliver on our AMG brand promise. Our customers can also look forward to a dynamic and emotional driving experience in this area. We ensure this with AMG-specific solutions, particularly when it comes to the drive system, suspension, brakes and, above all, sound,” says Jochen Hermann, Chief Technical Officer of Mercedes‑AMG GmbH.
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 75 percent. The top speed is limited to 250 km/h with the optional AMG DYNAMIC PLUS package. In the base version the AMG EQS accelerates from 0-100 km/h in 3.8 seconds (minimum 30 percent battery charge). Its maximum speed is limited to 220 km/.
AMG SOUND EXPERIENCE: emotional sound spectrum for a unique driving experience
Mercedes-AMG models have always stood for emotionality. The vehicle sound has always been an important part of the typical 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 speakers, a bass actuator and a sound generator to create a special sound experience in two versions: “Authentic” or, as an option, “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.
AMG-specific electric motors for perfectly balanced Driving Performance
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.
Added to this is the highly resilient thermal concept, which allows repeated acceleration manoeuvres with consistently high performance. The centrepiece of the sophisticated design is the so-called water lance in the shaft of the rotor, which cools it. Other AMG-specific cooling elements in the cooling circuit are special ribs on the stator and the needle-shaped pin-fin structure on the inverter, which is made of high-performance ceramics. In addition, there is the additional transmission oil cooler which also increases efficiency during cold driving, as it warms the transmission oil as needed.
Intelligent recuperation for efficient energy recovery
The new Mercedes-AMG EQS 53 4MATIC+ sets standards not only with its highly dynamic power delivery when accelerating, but also with efficient energy recuperation when braking. The recuperation output is up to 300 kW[2].
The driver can adjust the level of recuperation in three stages via switches on the steering wheel, and receive situation-related support from the ECO Assistant. Combined braking can take place until a standstill. With the help of the optional DRIVE PILOT, deceleration is automatic in response to detected vehicles ahead until they come to a standstill, for example at traffic lights.
New battery generation with a capacity of 107.8 kWh
The new Mercedes-AMG 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.
