Steer-by-wire stars on the new
COVER STORY
LEXUS
RZ 450E
The RZ battery rides low in the
chassis, is liquid-cooled and sealed
with urethane.
The steer-by-wire yoke makes extra room underneath it due to
the lack of a normal steering column.

The interior of the RZ is meant to be clean and modern while still invoking a
feeling of luxury performance.
Both trim levels come with a 14-inch touchscreen with controls
easy to use for anyone who has a smartphone. The USB-C era has
arrived with authority in the RZ, with three ports up front and two
in the rear.
Without a steering column in the way, Lexus has made available a
radiant heat panel that can warm the front driver and passenger's
legs and feet. One reason to do it, Higashiyama said, was for energy
management. With radiant heat from the seats and the front panel,
the main cabin HVAC system may be called on less, saving energy
overall. This is similar to a proposition supplier ZF offered at CES
2023, where it showed a heated seat belt with a similar thesis.
The 450e comes with a full suite of standard and available driverassistance
and safety tech, including:
* Pre-Collision System with Pedestrian Detection, powered by a
camera and millimeter-wave radar.
* Risk Avoidance Emergency Steer Assist, which can gently brake and
steer away from trouble during daytime parameters.

The easy-to-handle RZ was never hard to maneuver or unsure of
foot, whether on tight two-lane roads or highways.
* Left Turn Oncoming Vehicle Detection/Braking, to
first warn, then automatically brake the vehicle if the
driver is turning left in front of oncoming traffic.
* All-speed Dynamic Radar Cruise Control, which can
maintain safe distances from vehicles in front while
slowing to a complete stop and accelerating again.
* Advanced Park, which can automatically park with minimal
driver input.
* Traffic Jam Assist.
The RZ is assembled at Toyota's Lexus factory in
Motomachi, Japan. U.S. retail pricing starts at just less
than $60,000.
About that yoke: Lexus really doesn't want to call the
steer-by-wire interface a yoke. Asked what they want to
call it, the U.S. contingent said it has yet to be decided,
but that it definitely won't carry the name it has in
Europe: One Motion Grip, or OMG. LOL.
