Mercedes’ 2027 EQS details

Mercedes-Benz has turned the next EQS into a deeper overhaul, adding steer-by-wire and a yoke-like steering control to its flagship electric sedan. (group.mercedes-benz.com) Steer-by-wire replaces the usual mechanical link between the steering wheel and the front wheels with electronic signals, and Mercedes said the new EQS will offer it a few months after launch. The company said it will be the first German automaker to sell a production car with the system. (group.mercedes-benz.com) Mercedes said the flatter wheel shape improves the view of the driver display and makes entry and exit easier. The company also said the system has logged more than 1 million test kilometers and uses redundant signal paths, rear-axle steering and brake interventions as backups. (group.mercedes-benz.com) The EQS update lands in the middle of Mercedes-Benz’s broader product push. In February 2026, the company said it was rolling out more than 40 new models by 2027 and extending its Mercedes-Benz Operating System, or MB.OS, across more of its lineup. (group.mercedes-benz.com, group.mercedes-benz.com) MB.OS is the software layer that ties together infotainment, automated driving, body functions, and charging, with over-the-air updates across the vehicle. Mercedes has said that in-house hardware and software integration is central to its next generation of cars. (group.mercedes-benz.com, cars.com) Independent outlets that previewed the car on April 13 said the 2027 EQS also moves to an 800-volt electrical architecture, larger battery options, new motors, and much faster charging. Motor1 said the sedan goes on sale in the United States in the second half of 2026. (motor1.com, insideevs.com) Cars.com reported the new setup raises peak DC fast-charging to 350 kilowatts from 200 kilowatts on the current car, and Mercedes said 10 minutes of charging can add nearly 200 miles of range. Those reports also said the sedan keeps its cab-forward shape while getting modest exterior revisions rather than a full redesign. (cars.com, insideevs.com) That mix of visible restraint and deeper engineering work fits how Mercedes is now pitching the EQS: less as a cosmetic facelift, more as a reset for the brand’s electric flagship. The company’s own message is that the steering system, software stack and vehicle architecture are all moving at once. (group.mercedes-benz.com, group.mercedes-benz.com)
