Mercedes-Benz introduces steer-by-wire system and compact steering wheel on EQS model
Digital Revolution at Mercedes-Benz: EQS Ditches Steering Column for the “Steer-by-Wire” Future
The Stuttgart-based automaker's flagship is getting a major technological upgrade, aimed at correcting the model's commercial trajectory and redefining the driving experience. Mercedes-Benz is betting on eliminating the mechanical linkage and on a "spoke" steering wheel to recapture the electric luxury segment.
Although it was launched with great fanfare as the “S-Class of the electric age,” the Mercedes-Benz EQS has had a challenging journey. Controversial design and below-expected sales figures forced the German manufacturer to act quickly. After a facelift implemented in 2024 to “sweeten” the aesthetics and improve autonomy, the EQS is now moving to the next level: full digitalization of the steering.
Goodbye, steering column! What does Steer-by-Wire mean?
The most important new feature is the introduction of steer-by-wire technology. In simple terms, this system eliminates the physical steering column between the steering wheel and the wheels. The driver's commands are transmitted purely electronically, via sensors and actuators, a solution inspired by the aeronautics industry.
According to the engineers in Stuttgart, this change is not just an engineering exercise, but brings tangible benefits:
- Acoustic and tactile comfort: Without a direct metal connection, unpleasant vibrations from the road are no longer transmitted to the driver's palms.
- Variable agility: The steering ratio can be adjusted by software in real time. At low speeds (parking), the steering wheel requires a much shorter stroke, while at high speeds it becomes stiffer and more precise.
- Passive safety: Eliminating the metal rod from the passenger compartment reduces the risk of injury to the driver in the event of a severe frontal impact.
Did you know? Mercedes-Benz has tested this system over a distance of over 1 million kilometers, both on test circuits and in rigorous digital simulations, to ensure the system's total redundancy and safety.
The "Yoke" Steering Wheel: Form, Function and Visibility
Along with the new steering, the EQS also introduces a compact “yoke” steering wheel. While Tesla popularized the concept (with mixed success), Mercedes-Benz claims their approach is superior due to its integration with the steer-by-wire system.
Since it is no longer necessary to turn the steering wheel several times to turn completely (thanks to the variable ratio), the rectangular shape becomes much more ergonomic. The main benefits include:
- Increased visibility: The driver has an unobstructed view of the Hyperscreen dashboard and the road.
- Easy access: The compact steering wheel offers more legroom, making getting in and out of the car much easier.
Availability and Versatility
The new technology will not be limited to a specific engine version. Whether we are talking about the EQS 450+ or ??the AMG performance variant, customers will be able to tick this option on the equipment list. What's more, the system is fully compatible with all-wheel steering (rear-wheel steering), turning the EQS into an unexpectedly maneuverable car for its dimensions of over 5 meters.
However, Mercedes-Benz remains cautious. The steer-by-wire technology will be offered as an optional feature. Conservatives or those who prefer the "analog" feedback of a classic steering column can still opt for the traditional electromechanical system.
Conclusion: A bet on the future
With this upgrade, the EQS stops being just an “S-Class on batteries” and becomes a technological laboratory on wheels. It remains to be seen whether the elimination of vibrations and the new futuristic steering wheel will be the arguments needed to convince luxury customers to make the definitive switch to the Stuttgart-based manufacturer’s electric fleet.
