The RZ 450e will be getting a steer by wire system at a later date that "enables the electronic exchange of steering and road surface information between the advanced steering control and tires via electrical signals, not mechanical linkage."
PLANO, Texas (April 20, 2022) -- Lexus is proud to unveil details of the all-new 2023 RZ 450e, the luxury brand’s first global Battery EV (BEV).
AVAILABLE STEER BY WIRE WITH INNOVATIVE STEERING CONTROL ELEVATE THE HUMAN-MACHINE CONNECTION
Available in the U.S. at a future date, the Lexus-first Steer by Wire system enables the electronic exchange of steering and road surface information between the advanced steering control and tires via electrical signals, not mechanical linkage.
The control’s steering angle is set at approximately 150 degrees, thus greatly reducing the driver’s workload and eliminating the need for hand-over-hand operation at intersections, U-turns, parking, winding roads and other driving situations. Unhindered by a sizeable standard steering wheel, designers crafted the steering control’s compact shape and lowered the instrument meter’s placement to encourage driver engagement and environmental awareness.
A cockpit space encouraging even more engagement with the car has been achieved by minimizing driver eye movement during driving and naturally drawing the driver’s eyes forward. With Steer by Wire enabling the electronic exchange of steering and road surface information between the steering wheel and tires via electrical signals, Lexus focused on the quality and transmission speed of important driving information. The system achieves maneuverable and confidence inspiring performance through precise judgment, by blocking out unnecessary vibrations from the tires and brakes, only relaying vital driving information such as road information to the driver.
When Lane Tracing Assist is activated, the wheels are controlled as needed, allowing for gentle steering and vehicle movement. Furthermore, in addition to the vehicle’s overall maneuverability, the system provides nimble and agile performance on winding roads and high-speed stability on the highways by optimizing the steering gear ratio according to vehicle condition.
