Mercedes-Benz will bring steer-by-wire technology to production vehicles in 2026, becoming the first German manufacturer to do so.
The new Tesla-style system eliminates the traditional mechanical linkage between the steering wheel and front axle, instead transmitting steering input electronically. This approach allows more responsive handling and expanded design freedom while still prioritising safety.
With no physical connection, drivers will notice a distinctly different steering feel.
Mercedes-Benz claims the system improves urban manoeuvrability and allows for effortless parking without the need to re-grip the wheel. Integration with rear-axle steering (up to 10 degrees) further enhances agility and stability.
Tailored dynamics
By enabling variable steering ratios, steer-by-wire lets engineers fine-tune responsiveness across driving conditions. It balances comfort with sportiness - traditionally seen as mutually exclusive traits.
Vibrations from uneven surfaces, which typically transmit through the steering column, can now be filtered out almost entirely.
Interior flexibility also benefits. The system supports flatter steering wheels and more open cabin layouts. Entry and exit are made easier thanks to a lower steering wheel profile, while the absence of mechanical components allows for new vehicle architectures.
“Steer-by-wire is another big step towards the mobility of tomorrow,” said Markus Schafer, Mercedes-Benz CTO.
He added that paired with SAE Level 3 automation, the setup could support more immersive in-car entertainment - highlighting its flat wheel design and enhanced screen visibility.
Built-in redundancy for max safety
Safety is central to the technology’s deployment. Mercedes-Benz has engineered full system redundancy, including dual signal paths, actuators and backup power.
In the rare event of a failure, the vehicle retains lateral control through rear-axle steering and ESP-assisted braking.
Over two million test kilometres split between benches and real-world trials have validated the system’s reliability.
The SFU (steering feedback unit) recreates signature Mercedes steering feel, despite the lack of physical feedback. Tyre-road contact is modelled using wheel-specific data.
Coming next year
The move builds on a long lineage of steering milestones for Mercedes-Benz, from kingpin steering in 1893 to sidestick controls in late-90s concept cars. More recently, the brand introduced rear-axle steering in the S-Class and the Drive Pilot SAE Level 3 system.
With steer-by-wire, Mercedes-Benz is advancing beyond mechanical steering, aligning with broader trends in vehicle software, electrification and user experience customisation.
