Mercedes EQS Update: Larger Battery, New Technologies, and a Controversial Yoke
Despite Mercedes-Benz not planning to develop an entirely new generation of the EQS, instead offering a future S-Class in two variants—with an internal combustion engine and an electric one—the company has presented a comprehensive second update for this model. It includes a number of important technical improvements that could make the car more attractive to buyers.
Among the key changes are an updated powertrain and battery packs. Four versions are currently confirmed: EQS 400, EQS 450+, EQS 500 4Matic, and EQS 580 4Matic. The latter three are equipped with an 800-volt electrical architecture and new battery packs with a capacity of 122 kWh, promising improved energy density. The base EQS 400 model received a smaller 112 kWh pack.
Mercedes has also improved the charging capabilities of the electric sedan. It now supports DC fast charging with a power of up to 350 kW, allowing for the recovery of up to 199 miles (320 km) of range in 10 minutes.
Power, Range, and Revolutionary Steering
In addition to the new batteries, updated electric motors have been installed for all versions. The base EQS 400 delivers 362 hp, the EQS 500 4Matic—469 hp, and the top-tier EQS 580 4Matic develops 577 hp and 800 Nm of torque. The claimed WLTP range for the EQS 450+ version is an impressive 575 miles (926 km).
One of the most significant innovations has been the introduction of steer-by-wire technology, i.e., a wire-controlled steering system like in Lexus or Tesla. The steering ratio at low speeds is 4:1, which significantly facilitates maneuvering.
New Look and Controversial Interior
Externally, the updated EQS can be recognized by its redesigned front end with a new radiator grille, completely black and covered with dozens of three-pointed stars, as well as by new lighting with daytime running lights in the shape of stars.
The interior remains recognizable but has received a substantial update. The most noticeable and likely controversial change is the new yoke steering wheel, which resembles the one from Tesla. Importantly, Mercedes will continue to offer a traditional steering wheel with an electromechanical power steering system as an alternative to the new system.
The cabin also features the latest version of the Mercedes-Benz Operating System (MB.OS) and the new MBUX virtual assistant. The massive Hyperscreen remains in place, and new 13.1-inch entertainment screens have been installed for second-row passengers.
Pricing and Availability
Prices for the US market have not yet been announced. In Europe, the starting price will be from 94,403 euros for the base EQS 400. The EQS 450+ model will cost from 108,635 euros, the EQS 500 4Matic—from 123,285 euros, and the top-tier EQS 580 4Matic—from 134,732 euros.
This update demonstrates how rapidly the premium electric vehicle segment is evolving. Mercedes is investing significant resources into improving key parameters for buyers—range, charging speed, and steering innovations—trying to make the EQS a more competitive model. The introduction of steer-by-wire technology and the yoke indicates the brand’s readiness to experiment, following market leaders, even if it provokes an ambiguous reaction. The success of these changes in the market will depend not only on technical specifications but also on how ready buyers are to accept a new, non-traditional way of interacting with the car.
