Lexus has brought its first BEV to the USA! This is the #rz450e fully electric #ev
Here's what I found after driving the RZ for a week. Is this the luxury EV you've been waiting for?
The 71.4 kWh battery delivers on performance with a total system horsepower rating of 308 and a manufacturer-estimated 0-60 acceleration time of 5.0 seconds. It has an EPA-estimated range rating of up to 220 miles when equipped with 18” wheels and an EPA-estimated MPGe rating of 115/98/107 (city/highway/combined). When utilizing 20” wheels, the RZ has an EPA-estimated MPGe of 102/87/95 with an EPA-estimated range of up to 196 miles.
RZ 450e utilizes DIRECT4, an all-wheel drive system first introduced with the 2023 Lexus RX, which features a rear eAxle coupled with the engine and front motor. RZ’s DIRECT4 system utilizes two high-output, high-torque eAxle units that each drive a wheel set, one in the front (150-kW) and the other at the rear (80-kW). Three-point eAxle motor mounts, each using a lightweight aluminum bracket, are placed symmetrically on each side to counterbalance the eAxle’s torque.
The DIRECT4 system works to optimize RZ’s drive force, traction, and posture control (e.g., pitch and dive) in accordance with driving conditions and the load carried by each wheel. DIRECT4’s front-to-rear torque distribution has a maximum range of 100:0 to 0:100, depending on the driving situation.
Also lending to the RZ’s drive performance is the front MacPherson strut type suspension and rear trailing arm multi-link configuration with both specifically tuned and located to enhance handling balance, roll posture, and ride comfort.
At the rear, Frequency Reactive Dampers (FRD) are outfitted to the RZ’s suspension, altering the dampening force on the extension stroke in response to road surface frequency input. The FRD works to provide a high level of handling stability and helps to achieve a comfortable ride. With FRD and e-TNGA, key Lexus Driving Signature traits such as the precise control of sprung weight, along with natural posture changes, a tactile steering feel and the linear responses of steering, braking and acceleration operations are enabled.
Braking and Steering
Lexus Driving Signature is also reflected in the new Active Hydraulic Booster-G (AHB-G) braking system that works with the DIRECT4 system and RZ’s regenerative motor capability to reduce vehicle speed while helping to improve vehicle posture. With a new Vehicle Stability Control actuator and on-demand pressurizing system using a high-performance pump motor, this braking system provides a natural and responsive brake pedal feel. The front-to-rear brake force distribution is controlled by independent pressure regulation, contributing to a comfortable drive and stable vehicle composure while braking. Furthermore, ergonomic brake pedal pads are used for easy pedal changes and pedal depression.
In addition, an all-new Vehicle Braking Posture Control program adjusts front-to-rear brake force distribution according to a driver’s braking input as well as the suspension’s vertical inputs. This aims to improve handling and body posture while braking and turning.
A standard rack assist-type Electric Power Steering (EPS) system reduces the amount of steering input needed by utilizing a new motor and reduction gear setup that is installed parallel to the steering box. Moreover, a Motor Control Unit (MCU) with an integrated motor and motor current control ECU, reduces the EPS’ size footprint and minimizes operational noise.
