What Comes After RX?

By Gary S. Vasilash

Lexus has revealed the 2023 RZ 450e, the brand’s first electric vehicle. Like the RX—which it undoubtedly hopes the RZ will follow in the tire treads of—it is a crossover.

(The RX isn’t going anywhere, of course. It continues to be the linchpin of Lexus. In Q1 in the U.S. Lexus sold 64,365 vehicles, of which 26,795 were RXes.)

Lexus plans to have an electric version of all types of its vehicles by 2030 and to have full EV sales on a global basis by 2035.

So the RZ is the start of what promises to be an unfurling ribbon of new products powered by electricity.

Driven

One of the things that Lexus is touting for the vehicle is the DIRECT4 all-wheel drive system that basically distributes torque based on factors including speed, acceleration and steering angle. The distribution ranges from 100% to the front to 100% to the rear depending on conditions.

This is what the steering wheel of the future (as in late 2022) will look like: Inside the Lexus RZ 450 e. (Image: Lexus)

The vehicle has motors on both the front (201 hp) and rear (107 hp) axles (for a total of 308 hp). Cleverly, so as to keep things going smoothly even should someone mash the accelerator, there is a front-to-rear drive force ratio distribution between 60:40 and 40:60– there is said to be a linear feel as a result.

Also in this smoothness realm is the use of Frequency Reactive Dampers that work to adjust the force on the extension stroke so as to provide handling and comfort. (The objective is to create a drivable vehicle for those who like to imagine that they’re piloting the vehicle [which could go to the point of the available rectangular steering wheel, which looks like it could be in a flight deck] as well as for those who buy a luxury vehicle because they want to feel cossetted.)

And while on the subject of steering, know that there is a steer-by-wire system deployed and the steering control is setup so that the need for hand-over-hand steering movements is minimized. (One thing the shape of the geometric steering device does: maximizes visibility of the control panel.)

As an EV, there is the key question regarding range. The vehicle has a 71.4-kWh battery and it will provide an estimated range of 225 miles.

The RZ 450e will be available late this year.
