Lexus LF-30 concept shows the electrified future of Toyota’s luxury brand (w/VIDEO)

Since Lexus was created in 1989 as Toyota’s luxury brand, it has usually been used as a technological showcase, introducing new technologies that in later years trickle down to Toyota models (Optitron meters are on example). It has enjoyed autonomy to choose its direction and product portfolio, coming out with successes like the RX which was a game-changer when it appeared in 1997. And while the Toyota brand steadily gravitated towards electrification, Lexus stuck with big internal combustion engines that still had demand from its upper strata customers.

This is not to say Lexus has not been supporting hybrids; since the launch of the RX 400h in 2005, the brand has been among the pioneers in electrification technologies, examples being the two-stage reduction gear and the multi-stage hybrid system.

Like most global brands that want to continue their business into the next decade, Lexus now has to prepare for electrification on a bigger scale, as the ‘big picture’ for the Toyota Group dictates. At the same time, its upcoming generation of electrified vehicles must offer the brand experiences that have been part of the reason for its continuing success.

LF-30 – Lexus Electrified Vision in 3-dimensional form
The Lexus LF-30 Electrified concept unveiled at the 2019 Tokyo Motor Show targets a fundamental leap in vehicle performance, handling, control and driver enjoyment – even as mobility within our society continues to change with autonomous driving and vehicle electrification.

Presenting the vision in 3-dimensional form as the LF-30 concept, the technology of Lexus Electrified enables integrated control of powertrain, steering, suspension, and brakes, realizing the ultimate potential of the motor control technology cultivated in hybrid vehicles. With this technology, it is claimed that it will be possible to control the driving force to provide ideal vehicle posture according to each driving situation, enhancing safety and driving pleasure.

Lexus Advanced Posture Control technology regulates the drive-power output from high-torque electric motors to adjust vehicle posture in tune with human sensibilities. Completely independent control of front and rear drive wheels allows appropriate provision of front-wheel drive, rear-wheel drive, and all-wheel drive, depending on the driving situation.

Compact and lightweight drive-power units expand freedom in vehicle packaging and are used to enable the driver to enjoy ideal driving, regardless of the road surface or driving conditions. As a core element of Lexus Electrified, Lexus intends to widely apply this technology throughout its line-up of electrified vehicles.

New design freedom with a BEV
In taking up the challenge of expressing a new design that could only be achieved with a BEV (Battery Electric Vehicle) powered by in-wheel electric motors, Lexus visually articulated the LF-30’s unique energy flow. The car’s form is meant to visually express the energy created by the wheels set at the corners of the bodywork streaming toward the vehicle cabin and past the driver to directly flow onto the road surface. ‘Voltaic Sky’, the colour of the exterior, employs a leading-edge metal-infused coating to achieve a unique quality tinted by a touch of blue-green.

Taking advantage of a shape that has no defined bonnet – made possible by being a BEV – Lexus’ designers further evolved the signature spindle form to span the entire vehicle architecture. The window glass, which continually stretches from the front to rear, the muscular fenders, and the wing-shaped headlights now form the contours of the Lexus iconic spindle.

The shape of the body is fashioned with an elegantly flowing front which transitions into a linear and sharp rear. In addition to the wing-shaped headlights, the sharpness of the rear lights and side air intakes combine to achieve both excellent aerodynamics and cooling performance, resulting in styling fused with function.

The opacity of the side windows can be freely adjusted, providing occupants with expansive views of the surrounding scenery and a high level of privacy at night and in other situations. The colour of the front face of the car and luminescence patterns help identify from the outside whether it is being operated in its normal mode or in its autonomous driving mode, reflecting the brand’s pursuit of both a high level of styling and functionality.

Tazuna – new Lexus concept
Adhering to Lexus’ fundamental human-centered philosophy, the cockpit was designed based on the new Lexus concept of ‘Tazuna’. Inspired by how a single rein can be used to achieve mutual understanding between horse and rider, the steering controller-mounted switches and head-up display have been coordinated to a high degree, creating a space that enables the driver to focus on driving while controlling various functions, such as the navigation and audio system and driving-mode selection, without having to shift one’s vision or operate manual switches.

As an indication of the future image of a Tazuna cockpit, the LF-30 employs next-generation interfaces, such as gesture control and enhanced presentation of vehicle information through AR (augmented reality). With the layout of the front passenger seat echoing that of a first-class seat on an airliner, the interior is one in which a sense of openness and a sense of envelopment coexist.

The rear seats use artificial muscle technology to mold to their occupant, and can support various modes such as reclining, relaxation, and alert functions. A Mark Levinson audio system creates a next-generation listening environment, in which minute speaker control establishes ideal acoustic spaces for music listening pleasure for the driver and each passenger, and speakers built into the headrests not only provide an optimal audio environment but also have a noise-cancelling feature that contributes to enhanced quietness.

A glass roof above the rear seats features voice control and a gesture-controlled ‘SkyGate’ display window that uses AR to display various types of information, such as a realistic star-filled sky, user-favourite videos, and even navigation.

Sustainable materials
In addition to its unique design, the interior also indicates the direction of next-generation luxury by using sustainable materials to reduce environmental burden. Yakisugi (charred cedar), a traditional Japanese material, is used in the floor and steering controller while recycled metal was processed into fibres for use in creating the pleated door trim. This approach expresses Lexus’ distinctiveness and innovative spirit.

Based on the latest autonomous driving technology concept of ‘Lexus Teammate’, the LF-30 features advanced driving support functions in the form of a Chauffeur mode and a Guardian mode. Occupants can enjoy both comfort and peace of mind during autonomous driving with advanced posture control technology being employed. Furthermore, a self-parking function and a front-door pick-up function in which the LF-30 autonomously moves from driveway to doorstep will provide an especially high level of convenience.

The LF-30 also carries the ‘Lexus Airporter’ drone-technology support vehicle. Using autonomous control, the Lexus Airporter is capable of such tasks as independently transporting baggage from a household doorstep to the vehicle’s luggage area.

First production Lexus BEV next month
While we won’t see a model looking like the LF-30 in Lexus showrooms anytime soon, we will see the first BEV with a Lexus badge having its global debut next month. It’s not known if this will be adapted from a current model (like how Volvo has done with its XC-40 Recharge) or something entirely new. But it is confirmed that the first Lexus PHEV with a new dedicated BEV platform will be launched in the early part of the next decade.

By 2025, Lexus will have electrified versions of all its models, with the aim for sales of electrified models being higher than those of conventional internal combustion engine models.

Toyota to preview ultra-compact battery electric vehicle (BEV) it will start selling in 2020

After its pioneering role in mass producing hybrid vehicles in the late 1990s and then taking on a leadership position in the segment, it looks like Toyota plans to do the same for battery electric vehicles or BEVs. With hybrids, Toyota successfully brought the more environment-friendly powertrain into the mainstream, enabling volumes to become larger. This, in turn, allowed economies of scale to kick in and lower production and technology costs, making hybrids more affordable.

At the Tokyo Motor Show this month, the carmaker will display a new, production-ready ultra-compact BEV which it plans to start selling in Japan late next year. The ultra-compact 2-seater is specifically designed to meet the daily mobility needs of customers who make regular short-distance trips, such as the elderly, newly licenced drivers or businesspeople visiting local customers.

The next-generation mobility solution is designed to provide short-distance mobility while limiting impact on the environment. It has a range of approximately 100 kms on a single charge, can reache a maximum speed of 60 km/h and features an extremely tight turning radius.

Development chief Akihiro Yanaka said the BEV, which is less than 2.5 metres long and 1.3 metres wide, can be considered a mobility solution that can support Japan’s ageing society and provide freedom of movement to people at all stages of life.

New business model to popularise BEVs
Toyota is also pairing its planned launch next year with a new business model that aims to promote the wider adoption of BEVS in general. This includes examining every step of the battery pack’s life, from manufacture through sale, resale or re-use, and recycling to maximise its value.

In the near term, Toyota will focus on expanded leasing initiatives designed to recapture used batteries for evaluation and re-use as appropriate in pre-owned vehicles, as service parts, or even in non-automobile applications. Toyota is also developing peripheral services for BEVs such as recharging stations and insurance.

Karma Automotive to debut SC1 Vision Concept car in California this weekend

Karma Automotive, the company created from the previous Fisker Automotive purchased by a Chinese autoparts supplier Wanxiang Group, will reveal its design and technological direction with the North American debut of its SC1 Vision Concept car.

“The SC1 is a signpost to Karma’s future,” said Karma CEO Dr. Lance Zhou. “Designed and engineered in less than 12 months, SC1 is a full battery electric vehicle (BEV) that explores the brand’s striking design language and the innovative technology integration possible through our collaborative Open Platform strategy.”

Humanized communication system
The SC1 Vision Concept seamlessly integrates a new infotainment architecture with 5G connectivity and a humanized communication system with touch, voice, eye and graphical interfaces. Artificial Intelligence understands conventional language and commands, while a camera-based eye tracking system is capable of biometric identification, allowing for the multi-modal authentication of occupants. The eye-tracking system monitors a driver’s irises, eyelids and gaze – should the driver become distracted or fatigued, AI safely takes control of the vehicle.

With the use of 8 radar systems, 6 Lidar sensors, and half a dozen external cameras, the SC1 Vision Concept is fully equipped for autonomous motoring in the future. It will store information on cityscape and points of interest which are displayed in augmented reality.

Both driver and passenger can immerse themselves in comfort with an all-new surround audio system with dedicated sound environments for each of them. Karma says it will soon offer audio capabilities similar to the SC1 Vision Concept’s system through the company’s guided customization program.

New definition of luxury and style
“The SC1 Vision Concept draws its inspiration from Karma’s pioneering spirit,” said Andreas Thurner, Karma’s VP of Global Design and Architecture. “It is thought-provoking — it conjures a new definition of luxury and style with distinct Karma DNA.”

The SC1 Vision Concept features a one-off fluorescent orange paint scheme with flakes of violet mica capturing stunning sunset colours, juxtaposed by a darker palleted interior fading from black to deep indigo. A bold body design is reminiscent of an H-1 racing aircraft of the 1930s, with impressive length stretching from the car’s front axle to windscreen.

Striking patented articulating hinge doors open in a winged motion, gently rising up and forward, rotating around front wheels. The SC1 Vision Concept’s interior prioritizes simplicity and ease of use, eliminating excess to reveal a stratified design with a multi-dimensional in-cabin experience. The car’s battery is housed in a centre tunnel cascading down from dashboard into seats, before gliding upward to the decklid.

Toyota developing mobility vehicle as ‘last mile solution’ at 2020 Olympics in Tokyo

Providing ‘Mobility for All‘ is something Toyota Motor Corporation takes seriously. It is demonstrating this in its role as worldwide partner of the Olympic and Paralympic Games, specifically the one which will take place in Tokyo in 2020.

Besides various forms of transport that it has developed for different groups at the event, it is developing a special new product known as the Accessible People Mover (APM). This is a mobility vehicle designed expressly for use at the Games.

‘Last mile solution’
The APM will offer a ‘last one mile’ solution that helps transport as many people as possible to events and venues. These include athletes and staff related to the Games as well as all types of visitors with accessibility needs such as the elderly, people with impairments, pregnant women, and families with small children, among others. Part of the fleet of APMs, to number around 200 in total, will be used to support relief activities at events/venues during summer.

There will be two versions – a Basic Model and one with Relief specifications. The Basic Model will be for general transportation and feature 3-row seating. Up to 5 passengers can be carried and when used for passengers in wheelchairs, the configuration can be modified by folding the seats to allow the wheelchair rider in the second row.

Safety, comfort and convenience
With safety in mind, the position of the driver’s seat has been elevated and centrally located in order to allow the driver to see passengers and support their individual needs as they enter/exit the vehicle which is about 2 metres high.

The passenger seats are accessible from both sides of the vehicle, and the overall design considers varying customers’ needs, with safety bars on both sides to help passengers while entering and exiting the vehicle, and fitted with wheelchair anchor plates and ramps to enable the optimal access and transportation of wheelchair passengers.

The Relief specification is similar but has more open space to install a stretcher. In addition, to help convey people in a stable, safe way, a stretcher that can be attached/secured in the vehicle will also be equipped. There will also be space to allow 2 relief staff workers to sit immediately adjacent to the stretcher.

Needless to say, the APM – which has dimensions that are similar to a Toyota Avanza – will operate with zero emissions using a battery electric powertrain that should also be quiet. It can travel at a speed up to 19 km/h and a full charge should provide 100 kms of range.

Toyota, Sharp and NEDO to conduct road trials of high-efficiency solar cell panels

Sunshine does good and bad things for mankind. It provides light to see better for about half the day and it helps to dry clothes. However, it can cause skin cancer and in certain conditions, even start fires. Sunshine also contains energy which can be converted into electricity and at least one study suggests that solar power can be the world’s largest source of electricity by 2050.

Unfortunately, capturing sunshine to convert it in amounts large enough for practical usage has required technologies that have taken a while to develop. In fact, research began as far back as the 1930s but it is only in the past decade that R&D has accelerated and advanced technologies have been developed which are also commercially viable.

Technological advances needed
While sunshine alone can’t power a car (the technology would need to be very, very advanced), it can be used for the battery packs in electrified vehicles. Currently, the battery packs are recharged by drawing electricity from public or household electrical supply stations or by regeneration in the car’s powertrain. Solar power can supplement this and has the potential of improving cruising range and fuel efficiency of hybrid vehicles.

In fact, Toyota has already been using the approach since 2010 in the Prius to provide power for the climate control system. In 2017, it went further by enlarging the solar panel on the roof to provide electricity for the battery pack. Later this month, NEDO (a national R&D organization in Japan), Sharp Corporation, and Toyota Motor Corporation will carry out public road trials to assess the effectiveness this approach with Sharp’s modularized high-efficiency solar battery cells.

Thin-film solar battery cells
These solar battery cells are in a thin film about 0.03 mm in thickness. This makes it possible to efficiently install the film to fit the curves of parts with limited space. The battery cells will be installed on the roof, bonnet, rear hatch door and other areas of a Toyota Prius.

The idea is, of course, to maximise the area of coverage to capture as much sunshine as possible. By enhancing the solar battery panel’s efficiency and expanding its onboard area, Toyota was able to achieve a rated power generation output of around 860 W, which is approximately 4.8-times higher in comparison with the Prius Prime’s solar charging system.

In addition to substantially boosting its power generation output, the testcar will employ a system that charges the driving battery while the vehicle is parked and also while it’s being driven, a development that is expected to lead to considerable improvements in electric-powered cruising range and fuel efficiency.
