Mercedes Is Opting for Yoke Steering Wheels | Carscoops

      The new technology is expected to provide improved agility, comfort, and readiness for autonomy, but what will the implications be?

      Mercedes has unveiled a new steer-by-wire system that removes the mechanical link to the wheels. The yoke design enhances cabin space, visibility, and functions for both autonomy and in-car entertainment. A thorough testing phase guarantees safety through redundant systems and backup mechanisms.

      The German automaker is set to implement its steer-by-wire system in production vehicles by 2026, featuring a yoke-shaped steering wheel. Joining other automakers such as Tesla, General Motors, Geely, Toyota, and Lexus, Mercedes is adopting steer-by-wire technology, which replaces the conventional mechanical linkage between the steering wheel and the wheels with an electrical connection.

      Currently, it's unclear which model will be the first to receive this update, but a disguised prototype of the refreshed EQS has recently emerged, and it's speculated to be the leading candidate. This electric sedan is anticipated to launch next year, potentially equipped with the yoke-shaped wheel. The new S-Class may also adopt this technology, along with the next generation of their internal combustion engine models.

      Mercedes states that the new steer-by-wire system delivers "superior driving characteristics," which they claim enhances responsiveness on open roads and agility in urban settings. It is also designed to simplify parking, as the driver won’t need to re-grip the wheel. Additionally, the system is adaptable to different vehicle types and architectures, allowing for a wider array of comfort or sporty settings.

      However, some question Mercedes’ choice to implement the yoke. While it might free up space, it complicates fundamental maneuvers, such as low-speed turns or parking, leaving drivers longing for the familiarity and control of a traditional steering wheel. It appears to prioritize style and novelty over practicality and ease of driving.

      Mercedes’ steer-by-wire technology has been tested over one million kilometers in controlled environments and traffic conditions. For safety, the system is equipped with redundant architecture, onboard data, and a backup power supply to ensure driver control at all times. In the rare event of total failure, lateral guidance is maintained through rear-axle steering and targeted braking of individual wheels.

      Markus Schafer, Mercedes-Benz’s CTO, views steer-by-wire as a pivotal advancement in future mobility. He mentions that “the technology enables a unique customer experience that transcends mere steering. Paired with SAE Level 3 conditionally automated driving, it will provide an even more engaging entertainment experience over time. The flat steering wheel will offer an unobstructed view of the display while watching your favorite show.”

      Mercedes also points out that the first automobile, Carl Benz’s 1886 Patent Motorwagen, utilized a steering crank, and the traditional steering wheel made its debut with the 1894 Panhard 4HP. The company has previously experimented with alternative steering mechanisms in concept vehicles, including the innovative joysticks in the 1996 F200 Imagination and the F-Cell Roadster from 2009.

      As of now, other production vehicles featuring steer-by-wire systems include the Tesla Cybertruck, GMC Hummer EV, Rolls-Royce Spectre, Lotus Eletre, and the Lexus RZ 405e, the latter of which will be the first to introduce this technology in Europe later this year.
