Mercedes-Benz is offering the new EQS sedan with steer-by-wire technology. The steering system of this electric luxury sedan eliminates the mechanical connection between the steering wheel and the front wheels, transmitting steering commands instead via electrical wires. In Germany, this premium feature costs 2975 euros.
The standard equipment includes rear-wheel steering with a steering angle of up to ten degrees, as well as a new, flatter-designed steering wheel with an innovative airbag structure. The more compact steering wheel is intended to improve visibility of the driver display and facilitate getting in and out of the vehicle. It is available in black and, depending on the trim level, also in beige.
Steer-by-Wire reduces the required steering angle, especially at low speeds. According to the manufacturer, 170 degrees, or about half a turn, is sufficient from one end of the steering range to the other, eliminating the need for manual intervention. This system is designed to simplify maneuvering and parking tasks while reducing the effort required. Additionally, it is intended to enhance the electric EQS sedan’s driving stability and lateral agility.
The steering system works in conjunction with rear-wheel steering. This setup is designed to suppress unwanted vibrations caused by road irregularities that are transmitted through the steering wheel. For safety reasons, Mercedes states that steer-by-wire features “highly precise” sensors, powerful control units, and a redundant system architecture with independent signal paths. Even in the event of a complete system failure, lateral control can still be maintained through rear-wheel steering and targeted individual wheel braking assisted by ESP, according to the company.

More Information
A few months ago, Mercedes-Benz introduced an upgraded EQS sedan, with over a quarter of its components being renewed or revised. The new electric architecture includes 800-volt technology, newly developed drive units by the company, a two-speed transmission for the rear-wheel drive system, and larger batteries with optimized cell chemistry.
"The Mercedes-Benz Operating System (MB.OS) transforms the EQS sedan into an even smarter companion that understands, anticipates, and evolves alongside its driver," claim the Stuttgart-based team. "MB.OS integrates and controls every aspect of the vehicle. This supercomputer utilizes artificial intelligence (AI) as well as high-performance chips and is connected to the Mercedes-Benz Intelligent Cloud. As a software-defined vehicle, the EQS sedan remains up-to-date for years through over-the-air updates."
The 6-speed steer-by-wire system in the EQS works together with rear-wheel steering to effectively eliminate unwanted vibrations transmitted through the steering wheel.
