Mercedes-Benz Introduces Steer-by-Wire on the 2026 EQS, Revolutionizing the Steering Wheel with a Controversial Yoke Design

Mercedes-Benz has confirmed that it will introduce steer-by-wire technology in 2026, marking a significant turning point for the automotive industry. The first model to integrate this system will be the updated version of the Mercedes-Benz EQS, the brand's flagship electric sedan.

Steer-by-wire represents a radical change compared to traditional steering systems, as it completely eliminates the mechanical connection between the steering wheel and the front wheels. Instead, the driver's commands are transmitted via electronic signals. This allows for dynamic adaptation of the steering response: more responsive at low speeds to facilitate maneuvers and more stable at high speeds.

According to Mercedes-Benz, the system has undergone extensive testing, with over one million kilometers driven on test benches and on the road. Additionally, safety is ensured by a redundant architecture, with duplicated signal paths, additional actuators, and a backup power supply. In case of failure, systems such as rear steering and selective wheel braking still allow for vehicle control.

The Future of Mercedes and This Technology

The technology integrates seamlessly with the rear steering system already present on the EQS, allowing the rear wheels to rotate up to 10 degrees. This combination promises increased agility, directional stability, and a significant reduction in road vibrations.

One of the most noticeable innovations is the new "yoke" steering wheel, which replaces the classic circular shape. This design, characterized by a flattened top and a concave bottom section, is made possible precisely by steer-by-wire, which eliminates the need for multiple rotations of the steering wheel.

The goal is to enhance ergonomics, offer more legroom, and ensure a clearer view of the instrument cluster. This choice echoes solutions already seen on Tesla models, such as the Tesla Model S and Tesla Model X, where, however, the absence of steer-by-wire had generated criticism for poor practicality in low-speed maneuvers. Mercedes-Benz aims to avoid these problems thanks to the complete integration of hardware and software. The system will initially be introduced on the EQS, but is expected to expand to other models, including the upcoming S-Class and vehicles with traditional engines.
