The new Mercedes EQS confirms the Star’s tradition of technological leadership by introducing, just a few months after its debut, Steer‑by‑Wire technology. This is a first for a German manufacturer on a production model. Mercedes itself defines this innovation as the result of over a million kilometers of testing on test benches, tracks, and real roads. It is part of an architecture designed according to the company’s rigorous safety standards, with redundancy in signal paths, high-precision sensors, and powerful control units.

Mercedes EQS welcomes Steer-by-Wire technology
Steer‑by‑Wire elevates the driving experience, making it more precise, intuitive, and effortless. Electronic transmission replaces the traditional mechanical connection, eliminating unwanted vibrations caused by road surface irregularities while maintaining the typical Mercedes‑Benz feeling. Tire‑road contact is calculated through models based on the self-aligning forces of the steered wheels, allowing for sharp and responsive steering. Furthermore, the steering ratio adapts flexibly to different driving situations and operates in synergy with the rear-axle steering. Translated: at high speeds, the rear wheels steer in parallel with the front ones for greater stability, while maneuvers and parking are simpler and require less effort from the driver.

Available on all engine versions
The Steer‑by‑Wire revolution is also reflected in the cabin. The steering wheel becomes more compact and flattened, visually expanding the space, improving the visibility of the driver display, and thus facilitating entry into the vehicle. The system is available in combination with all engine versions and with rear-axle steering up to 10 degrees. In any case, Mercedes-Benz will continue to offer traditional electromechanical steering as well.
