LF-Z Electrified Establishes Next-Gen Lexus Performance, Styling, and Technology

By Chris Stanley - March 30, 2021

Lexus plans to introduce 20 new or improved models, including more than 10 electrified models by 2025 that take inspiration from the LF-Z Electrified concept.

Today Lexus debuted the LF-Z Electrified, a conceptual BEV that incorporates driving performance, styling, and technologies envisioned for realization by 2025. The goal here, according to Lexus, isn’t to launch the LF-Z, specifically, but to use it as a philosophical benchmark for what the brand plans to offer in the next five to ten years.

It features “ideal dynamic balance” achieved through the optimal placement of the battery and high-output electric motors, as well as, among others, a new four-wheel driving force control technology known as “DIRECT4” that generates a superior and highly flexible driving performance, setting the LF-Z Electrified apart from conventional vehicles. Also, in the near future, Lexus plans to incorporate technologies and advanced infotainment functions that will further enrich our customers’ mobility experience.

The LF-Z Electrified evolves the “Lexus Driving Signature,” a unique Lexus driving experience that aims for a linear response that is faithful to the driver’s intentions, including the feeling of seamlessly connecting deceleration, steering and acceleration in all driving situations. The LF-Z Electrified achieves an ideal balance and inertia by optimally positioning the battery and motors. The electrification technology allows for innovative packaging and design, and raises the Lexus Driving Signature to an even higher level by significantly evolving the basic performance of the vehicle.

By orienting the battery assembly longitudinally under the floor of the vehicle, the chassis becomes more rigid and the vehicle’s center of gravity is lowered for improved dynamics. In addition, this design helps mitigate vibrations and unpleasant noises from penetrating the passenger cabin. The Lexus DNA of quietness and ride comfort has evolved dramatically yet remains.

The new four-wheel-drive force control technology, DIRECT4, allows the drive force of the high-torque motors to be controlled freely, enabling the vehicle’s posture to be finely controlled according to human senses and inputs. In addition, by controlling the front and rear drive wheels independently, the system can provide the appropriate drive system – e.g. front-wheel drive, rear-wheel drive, or all-wheel drive – for each driving situation. The system controls the distribution of driving force through the seamless orchestration and calculation of accelerator pedal application and steering wheel operation, resulting in powerful acceleration and exhilarating cornering performance that aligns near-perfectly to the driver’s will.

The use of steer-by-wire eliminates the need for a mechanical connection through the steering shaft, resulting in a more direct response between steering operation and driving force. This enables the vehicle to turn with less steering angle – and more precision – in response to driving conditions.

LF-Z Electrified as the Future of Lexus Styling

The LF-Z Electrified, as a study model that suggests the direction of the evolution of Lexus styling, aims for a simple and captivating shape rooted in strong proportions and a distinctive appearance. Specifically, the overall form, which starts low in the front and peaks toward the rear, as suggestive of a BEV, is composed of a continuous silhouette centered on a smooth cabin. Large-diameter wheels that transmit the power of the high-power electric motors to the road surface are situated as much as possible at the vehicle’s four corners for a wide stance with a low center of gravity.

Lexus has taken up the challenge of evolving the Lexus design icon of the spindle shape into a spindle body as the overall body architecture in a new form of expression. The aim was to create a three-dimensional design that transforms the form of the vehicle body itself into the icon of the Lexus brand and to continuously develop functional expressions and styling that keep abreast with the evolution of technology.

The use of DIRECT4, which freely controls the driving force of the four wheels, enabled styling that evokes the image of dynamic driving in which the distribution of driving force is linearly shifted. The accentuation of the doors fluently transitions from the front wheels to the rear wheels, which are surrounded by shiny, projecting, flare-shaped molding.

In the rear, a clean and simple horizontal design combines with the molding that emphasizes the projecting wheels to express a powerful stance in support of a torque-strong driving force. Also, horizontally displaying “LEXUS” in the continuous slender rear combination lamp contributes to styling that, along with the front of the vehicle, symbolizes the next generation of Lexus.

LF-Z Electrified as the Future of Lexus Interiors

To embody to an even higher degree Lexus’s human-centered approach, which has been the foundation of the Lexus-brand since its birth, the cockpit was designed based on the new concept of “Tazuna” (“tazuna” is Japanese for “rein”). Inspired by the relationship between horse and rider, who communicate through a single rein, steering wheel-mounted switches and the vehicle’s head-up display have been highly coordinated to create a space in which various functions, such as the navigation system, audio system, and driving mode selection, can be performed while concentrating on driving and without movement of the driver’s line of sight or need to operate complicated switches.

While the cockpit is a key focal point, the low positioning of the instrument panel relative to the vehicle occupants and other measures are used to express a refreshing minimalism and a space that offers true Omotenashi.

The entire interior has been made a clean and high-quality space by a form that seamlessly connects the cowl to the front doors and on to the rear doors. Also, a panoramic roof uses long plates of glass that bring about a feeling of openness, emphasizing the minimalist environment.

While the augmented reality head-up display, gauges, touch display, and other information-provision functions are grouped into a single module, driving system functions are concentrated around the steering wheel. This suggests the direction of next-generation Lexus interior styling, with expanded forward visibility and the driver being naturally invited to look forward.

The Future of Lexus

By 2025, Lexus plans to introduce 20 new or improved models, including more than 10 electrified models such as BEVs, plug-in hybrid electric vehicles(PHEVs), HEVs, in line with the needs of each country and region around the world and based on the concept of offering the right products in the right place at the right time.

In addition to strengthening and expanding its core sedan models and SUV lineup, Lexus will pursue the possibility of rolling out models such as sports models that continue to provide the fun of driving, a car that redefines the concept of having a chauffeur, and new genres that have never before existed. In doing so, it will take on the challenge of providing new value that exceeds the expectations of its diverse customers.

Lexus aims to offer electric variants of all its models by 2025, with the sales ratio of electric vehicles exceeding that of gasoline-engine vehicles. By 2050, Lexus aims to achieve carbon neutrality throughout the lifecycle of its entire model lineup – from the manufacturing of materials, parts and vehicles, to vehicle logistics, to the final disposal and recycling of older vehicles. In this perspective, and with a clear mission to achieve carbon neutrality, Lexus will reduce the environmental impact of materials’ manufacturing processes.
