Mercedes-Benz Launching Steer-By-Wire System in 2026 EQS
Mercedes-Benz is set to roll out its first steer-by-wire system in 2026, joining other innovators in replacing traditional mechanical steering with fully electronic controls. The debut model is expected to be the updated EQS, the brand’s flagship electric sedan, scheduled for a refresh next year.
The steer-by-wire setup eliminates the physical link between the steering wheel and the front wheels, using electronic signals instead. Mercedes claims this technology improves responsiveness, enhances handling, and reduces steering effort. With a variable steering ratio, the system adjusts input based on speed—tightening at low speeds for easier parking and relaxing at higher speeds for more control on highways.
In a move echoing trends seen in the Tesla Cybertruck and Lexus RZ, Mercedes will also replace the traditional round wheel with a flat-bottomed yoke. This modern design improves dashboard visibility and frees up space, especially when paired with SAE Level 3 autonomous driving.
To ensure safety and reliability, Mercedes includes full redundancy: dual sensors, actuators, and backup power. This means the vehicle remains operable even in the unlikely event of a system failure.
With over one million miles of testing already logged, the steer-by-wire system is primed for integration in models like the EQS and S-Class—vehicles that also benefit from rear-wheel steering. The 2026 EQS is expected to be the first production Mercedes to feature this advanced steering tech.
