The Lexus RZ performs it secure, however the crossover will finally be supplied with a Steer by Wire system that encompasses a yoke steering wheel.
We just lately took a spin in a prototype and I can’t recall laughing extra throughout a check drive. Earlier than we get too far forward of ourselves, the Steer by Wire system replaces a mechanical linkage with electrical alerts.
Steering inputs are registered and this info is fed to an actuator that controls the steering itself. The automotive additionally sends suggestions to the yoke, so drivers have a way of what’s happening.

That’s over simplifying issues, however Lexus says the system “achieves maneuverable and confidence inspiring efficiency by way of exact judgment, by blocking out pointless vibrations from the tires and brakes.”
That is solely a part of the story as Lexus set the steering wheel’s lock-to-lock at roughly 150 levels and this eliminates the necessity for hand-over-hand operation. In laymen’s phrases, it makes the steering way more direct as even a slight motion can have a pronounced affect.

That being mentioned, the steering ratio modifications based mostly in your pace. That is supposed to assist enhance maneuverability at low speeds in parking tons and garages, whereas retaining the automotive secure at larger speeds.
Whereas this sounds good in concept, it doesn’t precisely work nice in observe. When driving slowly, it’s exhausting to gauge the quantity of steering wheel enter wanted and this leads to a twitchy experience that’s removed from nice. Issues quiet down at larger speeds, but it surely’s exhausting to be clean and I took out a cone or two throughout my preliminary run.
That being mentioned, there’s little doubt drivers will get accustomed to the expertise over time. I solely put in a couple of laps on a brief course, so we’re undoubtedly not writing off Steer by Wire fairly but.
Shifting on, the yoke is sure to attract consideration because it encompasses a rectangular design in addition to distinctive switchgear. The yoke feels comfy sufficient, however turning a circle is far more pure than making an attempt to rotate a rectangle.
Whereas Lexus might have simply put in the yoke and referred to as it a day, engineers determined to go the additional mile and revamp the cabin to “encourage driver engagement and environmental consciousness.” As a part of this effort, the digital instrument cluster has been moved again 1.4 inches (36 mm) and raised by 1.5 inches (38 mm). The distinction is notable and it’s a lot simpler to see the cluster.
Lexus notes the yoke helps to enhance entry and egress, however these weren’t issues to start with. The yoke additionally appears barely misplaced within the RZ because the crossover is pretty typical and doesn’t rock the boat. It’d be one factor in an LFA successor the place house would presumably be restricted, however right here it feels pointless.
All that being mentioned, we’ll maintain off our last judgment till we get slightly extra time behind the wheel yoke.
