Mercedes-Benz has released the 2027 EQS electric sedan. This is likely the last major update to the EQS before it becomes obsolete.
The new car has undergone a comprehensive technological upgrade, with significant improvements in almost every core indicator, from the 800V architecture, longer range, and steer-by-wire to enhanced energy recovery and a smart cockpit. However, it still retains the controversial “teardrop” shaped exterior. Mercedes-Benz will later launch a pure electric version of the S-Class to inherit the technological mission of the EQS, but with a more traditional design style.
Full Specifications of the 2027 EQS Mercedes-Benz
The 2027 EQS is scheduled to launch in the US in the second half of 2026. Mercedes-Benz claims that more than a quarter of the vehicle’s components are “new, updated, or optimized,” with the most significant change being the upgrade of the vehicle’s electrical architecture from 400V to 800V, enabling DC fast charging power of up to 350 kW. When connected to an 800V charging station, the EQS can replenish approximately 320 kilometers of WLTP range in just 10 minutes.
Furthermore, its battery has been upgraded from 118 kWh to 122 kWh, and the anode material uses a new chemical system of silicon oxide and graphite, while reducing the amount of cobalt used. The single-motor rear-wheel-drive EQS 450+ has a WLTP combined range of 925 kilometers, an improvement of 109 kilometers compared to the current model. Mercedes-Benz stated that all versions of the EQS will achieve significant improvements in range.
Another noteworthy new technology is the steer-by-wire system, which will be the first time Mercedes-Benz has introduced this feature in a production vehicle. Customers can opt for a near-rectangular yoke steering wheel (which Mercedes-Benz calls a “steering rudder,” with a rotation angle of only about 270 degrees, less than a full rotation). The vehicle’s computer determines the distribution of steering angle between the front and rear wheels based on vehicle speed and driving mode: it is more responsive to steering input when parking at low speeds, and reduces the steering ratio to improve stability at high speeds.
With the optional steer-by-wire system, the maximum rear wheel steering angle increases from 4.5 degrees to 10 degrees, further improving the vehicle’s maneuverability in narrow road conditions. Of course, if users prefer a traditional round steering wheel and electromechanical steering system, Mercedes-Benz also offers the standard configuration.
In terms of energy recovery, the 2027 EQS increases regenerative braking power by one-third, reaching 385 kW. For reference, the recently released all-electric GLC has a maximum regenerative braking power of 300 kW, and Mercedes-Benz claims that the electric motor handles 99% of the braking task, so the new EQS is expected to have an equally low frequency of friction braking intervention.
In terms of intelligent features, the new car is equipped with Mercedes-Benz’s latest MB.OS system and the iconic 56-inch triple screen, introduces a multi-agent AI assistant, and deeply integrates Google Maps.
The “zero-level” interface can learn the user’s most frequently used functions through AI and display them directly on the main screen as widgets, reducing the tedious operation of multi-level menus.
Meanwhile, its driver assistance systems have also been enhanced, with a total of 10 cameras and 27 sensors throughout the vehicle, supporting automatic lane changing, evasive steering, and automatic parking. However, it should be noted that Mercedes-Benz has not offered the Level 2++ “Drive Pilot Assist” system, which will debut on the CLA electric sedan, in this vehicle—the latter allows for hands-free driving in the city, but still requires the driver to remain alert.
In terms of appearance, the 2027 EQS retains the controversial “teardrop” single bow profile, with a drag coefficient of 0.20Cd, leading the industry.
However, the front end has also been adjusted: it retains the slender and sharp headlights and the continuous LED light strip, but the headlights now feature a complex three-pointed star emblem. The “fake grille” panel between the headlights adopts a design style similar to the CLA and GLB. Some foreign media believe that this change actually lowers the vehicle’s perceived quality, and unlike the gasoline-powered models, the fake grille is not surrounded by a high-gloss black trim.
Other exterior tweaks include new wheel designs and subtle embellishments. The taillights have also been subtly redesigned, featuring spiral-shaped LED elements to emphasize visual width and luxury. Furthermore, Mercedes has brought the heated seatbelt function down from the S-Class, which the company claims not only provides comfort in cold weather but also encourages passengers to remove heavy coats, allowing the seatbelts and safety systems to perform better in the event of an accident.
For users who seek personalization, Mercedes-Benz also offers the “Manufaktur Made to Measure” customization program, providing over 100 paint colors and numerous exclusive interior options, attempting to bring the EQS from the feeling of “mass production” into the realm of “tailor-made”.
Mercedes-Benz has not yet announced the specific price of the 2027 EQS. It is currently known that several versions will be offered: the EQS 450+ is a single-motor rear-wheel drive version with the longest range; the EQS 500 4MATIC and EQS 580 4MATIC are both dual-motor all-wheel drive, equipped with an integrated decoupling unit on the front axle that can quickly disconnect the front motor to save energy when not needed, and then “lightning-fast” reconnect it when traction or rapid acceleration is required. Furthermore, thanks to dual-axle energy recovery, these two versions offer the highest regenerative braking power.
