Mercedes-Benz has unveiled the EQS, a standalone model in the S-Class lineup. The electric luxury sedan will be launched in late summer 2021.

The one-bow design of the new Mercedes-Benz EQS stretches over a length of 5216 mm with a wheelbase of 3210 mm. The electric S-Class is 1926 mm wide and 1512 mm high. With its coupe-like basic shape and its flat windshield pulled far forward, narrow and adjustable radiator shutter and smooth underbody, the Mercedes EQS is the first production vehicle in the world to achieve a cw value of 0.20. In addition to low fuel consumption, this also results in low wind noise, which has been further reduced with measures such as retractable door handles, acoustic laminated glass windows and an A-pillar with a specially shaped decorative bar.

Automatic comfort doors are available as an option. When approached, the door handles first extend, then the door opens – and closes – fully automatically. The interior of the four-seater is available in eight coordinated color combinations, with comfort or sports seats (AMG Line). In addition to the active ambient lighting or the Burmester surround sound system, the highlight is the MBUX Hyperscreen, which is available at extra cost and combines three displays on a 141 cm wide screen band: the instrument cluster for the driver, the infotainment display, and a display for the front passenger.

The system’s adaptive AI software adjusts to the driver’s needs. Navigation Electric Intelligence calculates the best route, including charging stops, and takes into account topography, route, ambient temperature, speed, heating and cooling needs. The EQS can be parked via smartphone and is prepared for Automated Valet Parking. New vehicle features can be activated via Over-the-Air (OTA) updates.

All EQS use a 400 V architecture and are driven by a Permanently excited Synchronous Machine (PSM) on the rear axle, while the 4Matic all-wheel-drive versions also have an electric motor on the front axle. Torque Shift allows intelligent and continuously variable distribution of drive torque between the front and rear axles. The chassis is related to that of the S-Class. A four-link axle operates at the front, a space-steering axle at the rear. Adaptive air suspension is standard, as is rear-axle steering. The EQS travels on aero wheels ranging from 19 to 22" in size.

Start with two versions of the EQS

The EQS 450+ with rear-wheel drive produces 245 kW (333 PS), maximum torque is 568 Nm. The EQS 580 4Matic produces 385 kW (523 PS) and a maximum torque of 855 Nm. The top speed of the luxury sedans, which weigh around 2.5 t, is a regulated 210 km/h. The driver can choose between Comfort, Sport, Eco and Individual driving modes. The strength of the recuperation power enables deceleration to a standstill and can be set in three stages via shift paddles on the steering wheel. Depending on the version and equipment, it should be possible to achieve a WLTP range of up to 770 km.

The batteries consist of ten or twelve cell modules and have a usable energy content of 90 and 107.8 kWh. At fast-charging stations, the EQS can be charged at up to 200 kW. Thermal management allows charging of up to 300 km range in 15 min. At home or at public charging stations, the EQS can be charged at up to 22 kW with AC using the optional on-board charger. The range is up to 770 km. The cobalt content has been reduced to 10 %, and the optimized active material consists of nickel, cobalt and manganese in a ratio of 8:1:1.
