Mercedes-Benz to Add Steer-by-Wire to 2026 EQS

Mercedes-Benz has unveiled plans to introduce steer-by-wire technology in its facelifted EQS electric sedan, marking the first time a German automaker will bring the system to series production vehicles starting in 2026. The innovation replaces the traditional mechanical connection between the steering wheel and front wheels with electronic signals, sensors, and actuators, aiming to enhance driving precision and comfort in the luxury electric flagship.

The system, which debuted in prototypes and has undergone more than one million kilometers of testing on benches, tracks, and public roads, allows for dynamic adjustments to the steering ratio. At low speeds, it reduces the lock-to-lock wheel rotation to about 170 degrees, simplifying parking and urban maneuvering without the need for drivers to readjust their grip. At higher speeds, the ratio extends for greater stability, working in tandem with the EQS's optional 10-degree rear-axle steering to improve lateral agility and eliminate vibrations from uneven surfaces. Mercedes-Benz officials described the technology as elevating the driving experience to a new level, preserving an intuitive feel while optimizing sportiness and comfort.
