How does steer by wire work? | All-New Lexus RZ 450e

The One Motion Grip steer-by-wire system is one of the most significant new technologies featured in the all-new, all-electric Lexus RZ. There is no mechanical link and no conventional steering column; instead, an electrical connection is used to send inputs from the steering wheel and the wheels. The result is instant response and more precise steering control.

The driver will also notice less steering wheel sway when travelling over rough roads; stable control and correction in strong crosswinds; and excellent straight-line performance on angled surfaces. Steering feel is important for driver confidence and control. Lexus engineers have ensured the system still provides feel and feedback at all times, maintaining a strong connection between driver and car.

The optional One Motion Grip steer-by-wire system comes with a new steering yoke, replacing the traditional steering wheel. The steer-by-wire technology requires less steering effort from the driver: with only a 150-degree turn of the yoke needed to move from straight ahead to left or right lock, there is no need for hand-over-hand turns.
