Lexus announces the global debut of the new UX 300e, a significant evolution of the brand’s first production BEV model. The updated UX 300e joins the new UX 200/250h announced earlier this year, with deliveries scheduled to begin in spring 2023.

Since the 2005 launch of the RX 400h, the world’s first hybrid SUV, Lexus has been a pioneer of electrification in the luxury market. Based on the electrification vision “Lexus Electrified” announced in 2019, Lexus aims to meet the diverse needs of global customers through a broad range of electrified vehicles, from HEVs to PHEVs and BEVs. Using electrification technology to significantly enhance fundamental vehicle performance, Lexus continues to refine the timeless joy of the automobile, through hallmark precision and sophistication. In 2020, Lexus launched UX 300e as the brand’s first production BEV model. In 2022, this was followed by the introduction of the Lexus RZ, a dedicated BEV model. As of the end of August 2022, cumulative sales of Lexus electrified vehicles stand at approximately 2.3 million units, as the brand accelerates their development and adoption to contribute to the realization of a carbon-neutral society.

In addition to its maneuverable body size and unique “UX” urban compact crossover design, the UX 300e is highly regarded by customers seeking a distinctly quiet and refined BEV driving experience. The enhancements announced for the UX 300e are based on the relentless pursuit of perfection under an “Always On” philosophy. Enhancements unique to the BEV powertrain include a newly developed battery pack with capacity increased from 54.4 kWh to 72.8 kWh, resulting in a cruising range of 450 km*1―over 40% longer than the current model. The UX 300e also inherits the further refinements made to the dynamic precision of the UX series for confidence-inspiring performance, along with the expanded functionality of active safety technologies, and the evolution of advanced features through the latest multimedia system.

The updated UX 300e underwent rigorous testing and evaluation at Toyota Technical Center Shimoyama. The low center of gravity created by the under-floor placement of the BEV battery pack gives the UX 300e a natural performance advantage, as do standard rear Performance Dampers*2. For even more refined dynamics, body rigidity was strengthened with the addition of 20 spot welding points, and the Electric Power Steering (EPS) and shock absorbers were optimally tuned for the all-electric model.

When it comes to advanced technology, functionality of the “Lexus Safety System +” active safety technology was expanded with the aim of providing a safer and more secure driving experience. In addition, the latest multimedia system brings a larger, higher resolution touch panel display, the form and switch layout of the instrument panel and console area have been optimized, and two new Type-C USB connectors have been added to the front of the console for improved usability when charging devices.

“As Lexus’ first BEV model and a core part of the UX family, the UX 300e embraces the continual performance development and evolution of advanced technology applied to the UX 200/250h announced earlier this year, while enhancing the attributes unique to an all-electric vehicle. Most notably, based on an “Always On” philosophy we significantly extended the cruising range to further enrich the lifestyles of our customers. As a leading light for “Lexus Electrified,” the refinement of UX 300e is a key step on the path towards a carbon-neutral society.”

UX 300e main features

Unique BEV evolution to enhance customer lifestyle

The UX 300e takes full advantage of the electric powertrain configuration. As a unique BEV characteristic, it does not carry front-heavy objects such as an engine, allowing heavier components to be placed towards the center of the vehicle for optimum front/rear weight distribution and moment of inertia. The low center of gravity provided by the underfloor battery pack and the rear Performance Dampers*2 complement these attributes to refine the dynamics and enhance the sense of connection between the car and driver. The underfloor battery also acts as a sound barrier, and extra attention was focused on wind noise and road noise from gravel and other materials that became apparent in the absence of engine and transmission sounds. The result is a comfortable, quiet interior space.

The newly developed battery pack extends cruising range by more than 40% to 450 km*1 compared to the current model and achieves energy consumption of 166.7 Wh/km*1.

Further enhancement of refined, confidence-inspiring performance through strengthened fundamentals

A total of 20 spot welding points were added to the vehicle body around the side and back doors to improve structural rigidity. In addition, the car was driven extensively at Toyota Technical Center Shimoyama in order to further tune the EPS, shock absorbers, and other components. The aim was to achieve a linear response faithful to the driver’s intentions, such as the confidence-inspiring feeling of seamless deceleration, steering, and acceleration in all driving situations.

Expansion of active safety functions and equipment enhancements including the latest multimedia system

In order to achieve the ultimate goal of a mobile society where fatalities from traffic accidents are reduced to zero, the new UX has expanded functionality of the Lexus Safety System + active safety technology. The aim is to prevent accidents, further reduce traffic injuries and fatalities, and to lighten the burden on drivers. Furthermore, an advanced digital key feature enhances customer usability, enabling door lock/unlock and EV System Start via smartphone. A panoramic view monitor with transparent ground surface image display has also been added to show the road surface conditions and tire position beneath the vehicle.

Lexus Safety System +

  • An improved single lens camera and millimeter wave radar expands the Pre-Collision System safety capabilities by detecting bicyclists in the daytime and pedestrians at night. The system can detect oncoming vehicles before right turns in intersections, as well as crossing pedestrians approaching from the front, when turning right or left. In addition, Emergency Steering Assist has been added, allowing assisted steering support within the lane when triggered by the driver’s input.
  • Lane Tracing Assist (LTA), an advanced driving support function that assists in keeping the vehicle in the center of the lane, utilizes AI technology for lane recognition and expands the range of support, thereby achieving smoother and more consistent steering support.
  • A curve speed-control function that decelerates the vehicle in advance according to the size of an approaching curve has been added to Dynamic Radar Cruise Control (with an all-speed tracking function), which controls acceleration and deceleration so that the distance to an immediately preceding vehicle is constant within the speed set when driving on roads such as motor-vehicle-only roadways.
  • Emergency Driving Stop System supports the driver through audio and visual alerts and gentle deceleration if non-operation by the driver continues during use of Lane Tracing Assist. It then activates the vehicle’s hazard lamps and horn to alert those outside the vehicle to help prevent or reduce damage to the vehicle or others, while slowing and eventually stopping the vehicle within its lane. After stopping the vehicle, the system unlocks the doors and makes an emergency call through automatic connection to Help Net, which contributes to early driver rescue.

Digital Key

Installation of a dedicated smartphone app allows the smartphone to be used as a digital key for vehicles with this feature. In addition to being able to lock/unlock the doors via smartphone screen, the EV system can be started by pressing the power switch while holding the smartphone. The vehicle can be operated with just one smartphone, even if you own multiple vehicles compatible with a digital key. In addition, because digital keys can be shared between smartphones, it becomes easier and convenient to lend or borrow vehicles between far-away family members or friends.

Panoramic View Monitor

The Panoramic View Monitor combines images from the front, rear, left and right side cameras of the vehicle and displays them on the center display. The newly added under-body transparent display function combines images of road surface conditions taken in the past with an image of the vehicle underbody, thereby helping the driver to understand road surface conditions and tire position below the vehicle.

Latest Multimedia System and Improved Cockpit Usability

The multimedia system and connected services have been dramatically re-envisioned for an improved customer experience. The system features the latest 12.3″ touch display with larger size/higher resolution and intuitive state-of-the-art multimedia system for ease-of-use. In addition, G-Link*3 functionality has been greatly expanded to provide services that are more meaningful in our customers’ daily lives. We will continue to further the personalized customer experience by updating our multimedia systems through OTA*4 software updates. In addition, the shapes and switch layout of the instrument panel and console area have been optimized in accordance with the use of the touch-screen display, and two new charging USB connectors (Type-C) have been added to the front of the console for improved usability.
