From EV Review Ireland.
Welcome back to the channel! Today we are in beautiful Lisbon for a very special demonstration from Mercedes-Benz. We’re taking a deep dive into the future of driving with their all-new Steer-by-Wire technology. Using two identical EQS models—one with a traditional round steering wheel and one with the new Steer-by-Wire system—we’re going to put them through a high-speed slalom test to see if a digital connection can truly out-perform a mechanical one. From reduced driver effort to variable steering ratios, this is a look at how Mercedes is reimagining the relationship between the driver and the road.

Features
Variable Steering Ratio: Features a highly responsive system that allows for full wheel lock with only 170° of rotation, eliminating the need for hand-over-hand steering during tight manoeuvres [01:05, 05:51].
Enhanced Rear Axle Steering: When equipped with Steer-by-Wire, the EQS includes an upgraded 10° rear axle steering system as standard, reducing the turning circle by a full meter compared to the standard model [01:21, 01:42].
Advanced Force Feedback: Utilises dual motors on the steering column to provide simulated "road feel," allowing the driver to sense curbs or surface changes while filtering out unwanted vibrations [03:05, 03:17].
Multi-Layer Safety Redundancy: Incorporates a "diverse redundancy" architecture with two separate sensors, two communication lines, and two independent battery supplies to ensure the system remains operational even if a single component fails [03:41, 04:35].
Increased Cabin Space: By removing the mechanical steering column, Steer-by-Wire enables more flexible interior design concepts and improved legroom for the driver [02:15].
Competitive Technology Package: Launching first on the updated EQS, the Steer-by-Wire system is expected to be offered as a combined technology package with the enhanced rear-wheel steering for approximately €2,500 in Germany [06:17, 06:23].
