Mercedes-Benz has introduced steer-by-wire technology for its updated EQS electric saloon, eliminating the mechanical connection between the steering wheel and front wheels.
The German automaker said it is the first domestic manufacturer to offer the technology in a series-production passenger car.
Available to order in all EQS markets worldwide, the optional system costs from €2,975 (RM13,600) including VAT in Germany.
Unlike conventional steering, the system transmits driver inputs electronically to actuators that control the front wheels.
It also allows the EQS to use a flatter, Formula 1-inspired steering wheel, improving visibility of the instrument display and making entry and exit easier.
Steering wheel movement is limited to 170 degrees from lock to lock, removing the need for hand-over-hand steering during tight manoeuvres.
The package includes rear-wheel steering of up to 10 degrees, helping the large electric saloon negotiate confined spaces.
Mercedes-Benz said the electronically controlled system also filters out unwanted vibrations from uneven road surfaces while adjusting steering response to different driving conditions.
Safety is addressed through redundant sensors, control units and independent signal pathways designed to maintain steering functionality if individual components fail.
In the unlikely event of a complete system failure, the car can still receive directional assistance through rear-wheel steering and selective braking controlled by its electronic stability programme.
The steer-by-wire system joins several major upgrades introduced with the latest EQS.
These include an 800V electrical architecture, new in-house-developed electric motors, a two-speed transmission on the main rear drive unit and larger batteries with improved cell chemistry.
The updated saloon also uses Mercedes-Benz’s MB.OS operating system, which integrates vehicle functions and supports over-the-air software updates.
