Powertrains The front motor of the RZ 450e is taken from the
front-wheel drive version of the bZ4X, while the rear unit is taken from the all-wheel drive version of the same car, making it quicker than the bZ4X/Solterra. Using the 'DIRECT4' system, front/rear axle torque output can be varied continuously from 100:0 to 0:100; during normal driving, the torque split ranges from 40:60 to 60:40.

Steer-by-wire system The
steer-by-wire system, which Lexus have branded "One Motion Grip" for some markets, comes with a
steering yoke and removes the physical connection between the yoke and the
steering rack. The position of the yoke is used to drive a motor attached to the steering rack, while a second motor provides feedback to the yoke itself. The effort required to turn the yoke varies in response to driving conditions. Regardless of the situation, the total rotational range of motion is 300 degrees, which removes any need to perform a hand-over-hand movement for which a conventional
steering wheel may be more suitable. In a hands-on test,
Motor Trend called the yoke "little more than a novelty" but declared the "steering system that minimizes movement by instantly and intuitively adjusting to ever-changing conditions ... [is] a brilliant bit of engineering that could well change driving for the better". But it was delayed in the production version and replaced with a conventional steering wheel.
Chassis The chassis takes advantage of structural adhesives, laser-based welding processes, and high-tensile steel to enhance rigidity and reduce weight; the hood is aluminum and the battery is carried underneath the passenger floor, contributing to the vehicle's low center of gravity. ==F Sport Performance models==
