Initially introduced on the fully electric RZ last year, the vehicle has since hit the market. However, it presently incorporates the conventional steering system as Toyota works through certain challenges inherent in the steer-by-wire system. Since its prototype stage, a significant enhancement includes the upgrade from a 150-degree steering ratio to a more responsive 200-degree steering ratio.
The automotive publication Autocar recently got a chance to experience the system's latest iteration and reported that the increased ratio contributes to a smoother, less abrupt steering experience while maintaining the vehicle's agility at lower speeds. Toyota's refinements have also reportedly simplified the process of reversing the vehicle.
Toyota has gathered input from a substantial number of individuals regarding the steering system, tailoring it to comply with stringent European and Chinese regulations. The steer-by-wire technology is set to debut in the Lexus RZ and the Toyota bZ4X, with the potential for future over-the-air software updates, though such updates are currently not permissible under existing laws.
This steer-by-wire technology is expected to be adopted by various other electric vehicles in the future. This includes upcoming Toyota and Lexus electric models that will be built on a new platform, which was highlighted with the LF-ZC concept at the Japan Mobility Show.
Simon Humphries, Lexus' design chief, expressed that the steer-by-wire system paves the way for revolutionary interior designs in their forthcoming models. He emphasized the potential for more open and streamlined interiors, stating that with fewer mechanical components necessary, there is less need for interior panels and coverings, thus allowing for greater design freedom.
