Updated EQS electric saloon is expected to be the first model equipped with firm’s new technology
Mercedes-Benz will launch its first car equipped with by-wire steering next year, allowing it to replace the traditional steering wheel with a yoke.
The system replaces the mechanical connection between the steering and the front wheels with an electronic connection – the ‘wire’ – that is said to provide a quicker responses and a greater bandwidth of feedback.
For example, the steering quickens at low speeds to reduce the physical effort required for manoeuvres such as parking.
And because the wheel no longer needs to be spun through multiple revolutions to achieve full lock, Mercedes has done away with the traditional wheel.
It is now a flat-bottomed yoke similar to that in the recently updated Lexus RZ, which is due to become one of the first cars sold in Europe with a steer-by-wire set-up.
This new design is said to free up knee-room, making it easier to get in and out of a car, as well as provide a better view of any interior display screens.
Mercedes claimed the new set-up also brings a more natural interaction with the rear-wheel-steering set-up available on its flagship models, such as the S-Class and EQS saloons.
The latter has been used as a test mule for the system, and given that it’s due a facelift within the next year, it could be the first Mercedes model to be equipped with the new technology.
Mercedes added that the removal of the physical linkage between the steering wheel and the front end of the car “almost completely” removes the feel yielded by rough road surfaces.
The set-up is backed by a second (redundant) group of sensors and cables, meaning you can still steer the car in the event that its main steer-by-wire system fails.
“Steer-by-wire is another big step towards the mobility of tomorrow, and we’re proud that we will be launching such a system in 2026,” said Mercedes tech boss Markus Schäfer.
He added that the technology also “enables a unique customer experience that goes far beyond steering alone”.
He suggested that, in combination with level-three automated driving (hands and eyes off the road in certain situations), the “flat steering wheel provides a better view of the display when streaming your favourite show”.
