The updated Mercedes EQS Saloon gets steer-by-wire technology, making the brand the first German automaker to offer the system in a series-production passenger car.
Instead of relying on a conventional mechanical connection between the steering wheel and front wheels, the system uses electronic signals to translate the driver’s inputs. The result? Just 170 degrees of steering wheel rotation from lock to lock, which should make parking and tight manoeuvres considerably easier.
There are a few cabin benefits, too. The flatter steering wheel improves the driver’s view of the digital instrument display and helps the interior feel more open. The system can also filter unwanted vibrations from rough roads before they reach the driver’s hands.
Mercedes-Benz has paired the technology with rear-axle steering, which turns the rear wheels by up to 10 degrees to improve low-speed agility and high-speed stability.
Safety remains a key concern with any steering system lacking a physical link. Mercedes says redundant sensors, control units and signal paths provide backup, while rear-wheel steering and individual wheel braking can help maintain control in the unlikely event of a complete system failure.
