In April 2022, Lexus revealed its first globally-available pure battery electric vehicle (BEV) model. The All-New Lexus RZ 450e embodies the unique Lexus vehicle design and driving experience created by advanced electrification technology.
The RZ possesses impressive fundamental performance by using high-precision motor torque control, as well as optimal battery and motor placement, to achieve ideal weight distribution and high response. The concept is called "The Natural" and is based on the DIRECT4 all-wheel drive force system that controls front and rear drive force according to driving and road surface conditions. It achieves driving performance where the vehicle directly responds according to the driver's input, taking the Lexus Driving Signature to an even higher level.
A Lexus-first One Motion Grip system and yoke-like advanced steering control create an enhanced relationship between human and machine via electrical signals, not mechanical linkage. Having this connection enhances the quality and transmission speed of imperative driving information. One Motion Grip achieves impressive vehicle manoeuvrability and confidence-inspiring performance through precise computational judgement and blocks out unnecessary vibrations from the tyres and brakes.
DIRECT4, a Lexus-first all-wheel drive force system, and the newly developed high-output eAxle motor continuously control the drive force of the four wheels with high precision. It works according to the ground contact load of the vehicle regardless of road surface and driving conditions to achieve an exhilarating driving experience in line with the driver's intention. Vital information such as cornering speed and steering angle help to optimise drive force distribution and helps attain excellent handling stability.
THE RZ 450e utilises a Lexus-first dedicated BEV platform (e-TNGA) to significantly evolve the fundamental performance of the vehicle and provide the exhilarating joy of driving. The platform offers high levels of stability and ride comfort by mounting the battery under the vehicle floor and features a low centre of gravity and moment of inertia.

Take a look closer at the exciting new design and pioneering features of the RZ 450e.
The design concept expresses seamless acceleration and a sense of torque unique to a BEV. The elimination of the internal combustion engine has changed the functional requirements of the front end and challenged Lexus to create a new visual identity through the adoption of a "spindle body" design. The interior is inspired by the BEV's dynamic performance, presenting a clean and nimble image. A sense of refinement and high-quality craftsmanship exists, even within a space pursuing functional essence.
In-cabin sounds convey the exhilaration of driving by establishing a dialogue between the car and the driver. Engineers have matched sound frequencies to the vehicle’s speed and sound levels during dynamic actions such as acceleration. The tone and acoustic transmission characteristics of the drivetrain’s sounds were tuned to ensure its pleasantness. Quietness is also pursued to maximise interior cabin comfort.
The philosophy of Omotenashi runs through The RZ’s cabin – a minimalist yet airy luxury environment. The flowing shape originating at the cowl and leading to the doors integrates with the low positioned instrument panel, while the simple door trim and console present a clean, wide-open impression.The combination of a clean, modern space and simple surfaces with a focus on texture, expresses a welcoming sense of freedom. The long wheelbase provides a spacious rear seat space and ample rear headroom providing a further sense of spaciousness for the passengers. In addition, the available panoramic roof further lends a sense of wide openness and front-to-rear expansiveness.
Ambient illumination offers a rich experience while driving. The recommended 14 colours represent the emotions and feelings experienced when viewing beautiful natural phenomena. In addition, the world's first In-ei illumination changes the shade of light projected on to the door trim ornament when the doors are opened and closed, adding new flair to the interior space.
“THE RZ HAS BEEN DEVELOPED WITH THE AIM OF CREATING A UNIQUELY LEXUS BEV THAT FEELS SECURE TO RIDE IN, IS PLEASING TO THE TOUCH, AND IS EXHILARATING TO DRIVE.”
Takashi Watanabe, Chief Engineer, Lexus Electrified Lexus International
The RZ uses the latest Lexus Safety System + based on the belief that it is important to develop world-class advanced safety technologies faster and adopt them into more vehicles. The addition of Proactive Driving Assist support situations and optimal control based on driver monitor linked driver conditions will further contribute to a safe and secure drive. Functions include Pre-crash safety which detects a driver looking sideways or falling asleep at the wheel, warning them at an early stage.
The centre display utilises a large touch display, with many functions integrated into the soft switches within the display. Close attention was paid to the size, shape, layout, and display information of the switches. This allowed the pursuit of the optimum shape and placement for intuitive operation, while also considering frequency-of-use for each function.
Over-the-Air (OTA) updates enable constant upgrades to the latest software. Even after purchase, new features are added, improving performance of the car, allowing it to evolve into a safer and more secure vehicle equipped with the latest driver-assist technologies. A smartphone can be used as a digital key for vehicles with this function. Carrying a smartphone allows the ability to lock/unlock the doors and start the engine without operating the screen. One smartphone can operate multiple vehicles if they are registered to the same digital key.
BEV-exclusive high-capacity batteries and silicon carbide power semiconductor elements in the inverter, as well as the incorporation of low-loss technologies, contribute to extending the single-charge cruising range of the vehicle, which is estimated to be 400 km (250 mi). High-output charging capability meets the needs of customers in each country. The RZ’s battery warming system allows for the charging of batteries in a short time, even in the winter and in colder regions. Improved battery control technology ensures a world-class battery capacity retention rate (90% or more after 10 years) and allows customers to confidently drive the vehicle for long periods of time.
