Lexus has premiered the LF-Z Electrified, a conceptual Battery Electric Vehicle (BEV) that incorporates driving performance, styling, and technologies envisioned for realisation by 2025. In the near future, Lexus plans to incorporate technologies and advanced infotainment functions that will further enrich its customers' mobility experience.
The LF-Z Electrified is symbolic of Lexus' brand transformation. To realise the significant evolution of basic vehicle performance using electrification technology, which is the aim of Lexus' 'Lexus Electrified' electrification vision, the LF-Z Electrified adopts a BEV-dedicated platform.
It features a new four-wheel driving force control technology known as 'DIRECT4', which uses the instant responsiveness of an electric motor's driving force to freely control the car's four wheels for superior and highly flexible driving performance that sets it apart from conventional vehicles.
By fusing the electrification technologies and vehicle motion control technologies it has long cultivated, Lexus aims to evolve driving performance in a way that better connects the driver with their vehicle.
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 LF-Z's centre of gravity is lowered for improved dynamics. In addition, this design helps mitigate vibrations and unpleasant noises from penetrating the passenger cabin.
The new four-wheel drive force control technology, DIRECT4, allows the drive force of the high-torque motors to be controlled freely, enabling the LF-Z'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, like front-wheel drive, rear-wheel drive, or all-wheel drive, for each driving situation. The system controls the distribution of driving force through the calculation of accelerator pedal application and steering wheel operation, resulting in powerful acceleration and exhilarating cornering performance.
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.
The LF-Z, as a study model that suggests the direction of the evolution of Lexus styling, aims for a simple shape rooted in strong proportions and a distinctive appearance. The overall form, which starts low in the front and peaks toward the rear is composed of a continuous silhouette centred on a smooth cabin. Large-diameter wheels are situated as much as possible to the four corners for a wide stance with a low centre of gravity.
The accentuation of the doors fluently transitions from the front wheels to the rear wheels, which are surrounded by shiny, projecting, flare-shaped moulding. In the rear, a clean and simple horizontal design combines with the moulding that emphasises the projecting wheels to express a powerful stance in support of a torque-strong driving force.
The LF-Z's cockpit was designed based on the new concept of 'Tazuna', which is Japanese for 'rein'. Inspired by the relationship between horse and rider, who communicate through a single rein, steering wheel-mounted switches and the LF-Z's head-up display have been highly coordinated to create a space.
In this space, 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, emphasising 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.
In the LF-Z Electrified, AI learns the driver's preferences and behavioural characteristics, providing constant support to the driver. Voice communication contributes to improved operability while driving. The voice recognition system uses the latest AI to recognise, learn, and adapt to a driver's habits and preferences, supporting with tasks such as determining driving routes and making restaurant reservations.
The use of a digital key allows family and friends to access the car without having to hand over a conventional key, in addition to operating the vehicle with a smartphone, such as opening and closing the door locks. Also, by enabling service providers to access the car via the digital key, it will be possible to provide vehicle-linked services such as package delivery to the car or car sharing, making life with a car even richer.
The E-Latch system makes door opening and closing smoother and safer. When boarding, the retractable door handle automatically appears above the LF-Z's surface when a driver or passenger approaches with key in hand. The door can be unlocked and opened smoothly by touching the sensor inside the handle.
When exiting the vehicle, the door can be opened by pressing the door-opening switch. As an added benefit, the LF-Z's sensors scan the surrounding environment for oncoming and adjacent traffic prior to passenger egress to provide an additional layer of passenger safety.
The panoramic roof uses electrochromic glass and is equipped with entertainment functions such as dimming for privacy and shade, or illumination to reflect the passing night sky. In the centre of the roof is a touch panel that connects the front and rear seats and is used for communication between passengers. The reclining rear seats are also equipped with a massage function.
The next generation Mark Levinson audio system can reproduce a concert hall-like audio experience. With the next-generation sound management function, active noise cancellation facilitates interaction or privacy amongst passengers, providing a quiet and comfortable interior space.
