Mercedes-Benz is looking at a steering wheel that does more than move up, down, in and out.
A newly described patent points to a wheel with an adjustable diameter, potentially giving drivers more space, a different hand position or a more compact, sporting feel from the same basic setup.
It’s the kind of cabin idea that sounds unusual at first, but it speaks to a real challenge in modern car interiors, where ergonomics, safety systems and driver preference all compete for room.
At a glance
- Mercedes-Benz has patented a steering wheel concept that can change its overall size.
- The design uses telescopic adjustment elements and is shown with a split, yoke-like layout.
- Mercedes describes potential comfort, access and sporting-use benefits, though production is not confirmed.
An adjustable wheel for different driving positions
The patent describes a steering wheel fitted with at least three telescopic adjustment elements on each side.
Rather than simply changing the wheel’s distance from the driver, those elements would allow the diameter itself to be altered.
In a larger setting, Mercedes suggests the wheel could suit drivers who prefer a more relaxed hand position or sit closer to the wheel.
In a smaller setting, it could create more clearance for taller drivers or make it easier to get in and out of the vehicle.
Mercedes also notes that reducing the size could give the wheel a more sporting, race-car-like feel.
A yoke-like layout with powered mechanisms
The patent drawings show a split, yoke-like design rather than a traditional circular steering wheel.
That shape is significant because it separates the concept from a conventional rim that merely expands or contracts in a familiar round form.
The wheel angle could also be adjusted independently of the standard steering-column height adjustment.
Mercedes envisions power-assisted motors controlling the mechanism, while hydraulic and pneumatic systems are also mentioned as possible alternatives.
Still a patent, not a production promise
As with any patent, the idea doesn’t guarantee a future Mercedes showroom feature.
Automakers regularly protect engineering concepts that may evolve, be shelved or influence later systems in less obvious ways.
Even so, the concept is notable because steering wheels have become one of the most contested parts of the cabin, especially as brands experiment with driver assistance, digital controls and unconventional interior layouts.
If Mercedes ever brings an adjustable-diameter steering wheel to production, its success would depend on how naturally it feels in daily use, not just how clever the mechanism is.
For now, it’s an intriguing look at how far the brand is willing to rethink a component most drivers still expect to be fixed, round and familiar.
