Lexus LF-30 Concept
In its continued efforts to deliver innovative and amazing experiences, Lexus unveiled its "Lexus Electrified" vision for an upcoming generation of electrified vehicles. Headlining this moment was the debut of the Lexus LF-30 Electrified Concept, which made its world premiere at the 46th Tokyo Motor Show.
Since the brand's creation in 1989, Lexus has endeavored to deliver to its customers innovative and amazing product and brand experiences that stimulate the five senses. Since the launch of the RX 400h in 2005, Lexus has led the world as a pioneer in electrification technologies such as the two-stage reduction gear and the multi-stage hybrid system which leverage technology to offer excellent performance and the direct driving sensation characteristic of Lexus Hybrid vehicles.
The "Lexus Electrified" vision unveiled today 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.
Evoking the original fun of driving, Lexus is developing new advanced posture control and other electrification technologies to further evolve driving pleasure, and to fundamentally transform the essence of luxury vehicles of the future. Towards this end, Lexus is drawing on the lessons learned developing the core technologies found in Lexus' popular range of gasoline-electric hybrids, including battery management, power control modules, and electric motors. In particular, 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 HV. With this technology, we can control the driving force to provide ideal vehicle posture according to each driving situation. Lexus endeavors to continue providing enjoyable and safer driving vehicles.
To advance this goal, Lexus plans to unveil its first BEV in November 2019―broadening our response to the needs of various regions around the world, including the development of HEVs, PHEVs, BEVs, and FCEVs. Moving forward after that, Lexus plans to expand its electrified vehicle lineup―we will launch our first Lexus PHEV and a new dedicated BEV platform early in the coming decade. By 2025, Lexus will have available electrified versions of all Lexus vehicle models, and we are aiming for the sales of electrified vehicle models to outpace those of conventional internal combustion engine vehicle models.
Lexus LF-30 Electrified highlights
'LF-30 Electrified' new concept embodies the vision of Lexus' electrification
The LF-30 Electrified concept vehicle embodies the "Lexus Electrified" vision. For its exterior styling the advanced image expected of a BEV has been channeled into artistic qualities that result in a futuristic form, and an interior that assertively weaves in autonomous driving and other new technologies aims to manifest Lexus' distinctive worldview. Performance is rooted in Lexus Electrified components, adding Lexus' latest technology to our leadership in development of HEV systems. Precise electric motor control enables instantaneous adjustments to posture not possible with conventional vehicles. Furthermore, the LF-30 Electrified employs numerous advanced technologies with a look ahead to the year 2030- such as a new-concept cockpit based on a human-centered design philosophy and a steer-by-wire system.
• In taking up the challenge of expressing a new design that could only be achieved with a BEV powered by in-wheel electric motors, Lexus visually articulated the LF-30 Electrified's unique energy flow. The vehicle form is meant to visually express the energy created by the wheels set at the corners of the vehicle body streaming toward the vehicle cabin and past the driver to directly flow onto the road surface.
• Taking advantage of a hoodless vehicle shape made possible by being a BEV, Lexus' signature "spindle" form has been further evolved 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 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 color of the front face of the vehicle and luminescence patterns help identify from the outside whether the vehicle is being operated in its normal mode or in its autonomous driving mode, reflecting Lexus' pursuit of both a high level of styling and functionality. The exterior color 'voltaic sky' employs a leading-edge metal-infused coating to achieve a unique quality tinted by a touch of blue-green.
To manifest in a higher dimension 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 Electrified employs next-generation interfaces, such as gesture control and enhanced presentation of vehicle information through AR (augmented reality). The resulting interior is one that provides comfort and convenience for both driver and passengers.
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. All switches and other controls being comfortably within reach and a gesture-control large-screen display for the passenger seat add to the achievement of interior comfort and convenience.
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-favorite videos, and even navigation.
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 fibers for use in creating the pleated door trim. This approach expresses Lexus' distinctiveness and innovative spirit.
With in-wheel electric motors, steering by wire, and Lexus Advanced Posture Control, the LF-30 can offer a dynamic experience unlike any currently available
To achieve a fundamental leap in vehicle performance, handling, control and driver enjoyment, the LF-30 employs numerous state-of-the-art technologies even beyond advanced posture control. In-wheel electric motors for each of the vehicle's four wheels and low positioning of the battery enable better handling of inertia and high-level driving performance. Autonomous driving technologies and drone support vehicle technologies look ahead to the year 2030 and the widely expanded value that vehicles can offer.
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.
Positioning Lexus Advanced Posture Control technology as a core element of the 'Lexus Electrified' vision, Lexus intends to widely apply this technology throughout its lineup of electrified vehicles.
The steer-by-wire system eliminates a mechanical connection to allow more flexible turning control depending on driving conditions, and a more precise steering feel aligned with the driver's intention. It also contributes to a greater sense of openness by allowing the steering controller can be shifted forward and out of the way during autonomous driving.
As a next-generation BEV, LF-30 uses wireless charging technology to simplify daily charging, and AI-based energy management to enable optimal distribution of electric power to both the vehicle and the home, and charging control coordinated with the user's daily schedule.
Onboard AI distinguishes the voices of vehicle occupants, and uses personalized information stored on the driver's control key to serve as a partner. It facilitates the adjustment of elements of the interior environment, such as air temperature and audio, and the setting of navigation routes and destinations, while also making proposals for activities after arrival. It also understands driver's preferences and helps them control the suspension and powertrain settings in real-time according to the driving scene.
The LF-30 Electrified 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.
Based on the latest autonomous driving technology concept of 'Lexus Teammate', the LF-30 Electrified 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 pickup function in which the LF-30 Electrified autonomously moves from driveway to doorstep provide an especially high level of convenience.
In addition to the LF-30 Electrified exhibition, the Lexus booth at Tokyo Motor Show will contain "Lexus Senses theatre", a space where people can experience the "stimulation of the five senses". It consists of two experience spaces, audio and visual. In Theater 1, the sensual engine sound of Lexus LFA stimulates hearing with 360 degree 3D sound.
Theater 2 offers a visually stimulating experience with the Lexus LC model by projection mapping - which changes its appearance according to the time of day and the viewing angle. In this booth layout you can appreciate the Lexus philosophy, while enjoying sensory stimulation through "real experience".

2020 Mazda MX-30
Mazda’s new proposal for satisfying diverse needs. Packaging that stimulates creativity through flexibility.
People spend a lot of time with their cars; they are a big part of our lives. This is why Mazda wants to make their car a place they can relax and be themselves and an experience that enriches their daily routine, raising expectations of good times and new possibilities. To achieve this, the interior of the MX-30 combines functionality based on the latest research into psychology and ergonomics with a design theme that creates the novel sensation of being “enveloped in openness.” At its base is Mazda’s characteristic driving environment, which builds on human-centric design to achieve the ideal driving position and implement the brand’s Human-Machine Interface (HMI). The MX-30 is focused on the emotional connection between car and person and aims to provide a space where people can relax and be themselves, including when they are not driving the car. A new experience begins the moment one opens the doors. Because the space puts the driver at ease, they can enjoy a pure Jinba-ittai driving experience on a deeper level than ever before. Likewise, when parked they can explore a variety of new ways to use a car. The MX-30 stimulates people’s creativity and offers an enriching time that allows people to connect in a variety of ways. Mazda hopes it will be a car that begins a new era and opens the door of new possibilities as wide as the freestyle doors themselves.
One of the most outstanding features of the MX-30 is its unique center-pillar-less Freestyle doors with custom-designed hinges that allow the front doors to open to 82° and rear doors to open to 80°. This not only makes entering and exiting the car and loading and unloading cargo easier but also provides easier access for strollers and wheelchairs. The wide angle to which the front doors open was designed to facilitate this wide variety of usage styles. For example, the layout and the absence of a center pillar make it possible to bring a stroller right up beside the rear seat and smoothly and comfortably put a baby into a child seat while maintaining eye contact. The front door is opened first, followed by the rear door, and both can be opened without changing position. Opening the freestyle doors wide provides a new view and, in addition to improving access, opens a range of new possibilities for enjoying the car. For instance, drivers may wish to take time out of their daily routine to stop by the park, open up the doors and listen to the sounds of nature for a few moments or to use the car like base camp from which to enjoy outdoor activities with their friends.
To further enhance the freedom of ingress and egress provided by the Freestyle doors, the height and shape of the door openings are designed in accordance with human characteristics. The rear door trim adopts a vertical grip that makes opening and closing the door easier and that does not place much burden on the wrist when reaching for it, even with the door wide open. The front seats are equipped with a walk-in mechanism that, with a single touch, folds the seatback forward and simultaneously slides the whole seat toward the front.1 The folding angle and slide distance were chosen in consideration of the occupant’s body movements, ensuring smooth entry to and exit from the rear seats. The cross-section of the side sills and shape of the side sill garnish are also carefully designed to facilitate smooth, effortless exit from the cabin.
Human machine interface (hmi) Floating console
The shift lever and commander control are positioned toward the front and the center armrest is high so these controls can be operated with the arm at a natural angle. The center armrest also adopts a slide mechanism. The layout affords all drivers a comfortable posture, regardless of their build. Cupholders are positioned in the deeply recessed area between the shifter panel and the center armrest. The height of the armrest makes both putting drinks in the cupholders and operating the commander easy and natural. A distinctive feature of the MX-30 is the opening in the lower area at the front of the console, which can be used as a storage space. It achieves a clean design that also offers added functionality.
7-inch touchscreen display interaction that brings you closer to your car
The MX-30 adopts a 7-inch touchscreen display at the front of the console that encourages closer communication between car and driver. When the driver opens the door and gets into the car, a subtly changing graphic appears on the screen. The graphic changes look depending on the time of day and the temperature outside and helps get the driver in the mood for driving. Once the car is switched on, it displays the air-conditioning controls and lets the driver know that the car is ready to go.
Touchscreen air-conditioning controls
The 7-inch display integrates design and function at the highest level by serving as a touchscreen air-conditioning control panel when driving. Temperature, airflow and seat heater adjustments can all be controlled via the touchscreen. The controls are displayed in simple fashion and functions are grouped intelligently so all operations can be performed intuitively and quickly. Push switches mounted on the display’s bezel offer alternative control over A/C on-off, auto control, temperature adjustment, fan speed and window demisting. These switches help ensure proper operation, even when wearing gloves.
The MX-30 shares the same basic cockpit design found on all Mazda cars, with a horizontally symmetrical layout centered on the driver. It offers a driving position that feels natural and enables the driver to focus confidently on the road ahead.
The MX-30 adopts electronic gear shifting. In keeping with Mazda’s philosophy of placing top priority on safety, the MX-30 uses the same stationary design as the company’s conventional AT shifters. That means the lever locks into each of the P-R-N-D positions, making it easier to determine what gear the vehicle is in at any given time. The shift pattern puts D (Drive) at the back, R (Reverse) at the front and P (Park) offset to the side at the front. This intuitive and simple scheme supports sure and safe operation.
The MX-30’s seating position is set relatively high to secure a clear and unobstructed view. Optimization of the way the hood appears from the driver’s seat makes it easier to recognize the position of the front nose, helping to give the driver a better sense of the vehicle and its proportions. Attention to these details improves driving ease in scenes that can otherwise make drivers nervous, such as when driving on narrow roads or in parking lots. The shape of the rear door glass and quarter windows were carefully designed in accordance with studies on human characteristics. This enables drivers to turn their heads in place and clearly see vehicles diagonally behind the MX-30, allowing him or her to change lanes or back up with greater confidence.
To create a sense of being “enveloped in openness,” the front seats of the MX-30 are separated by a floating console. This not only creates an open space between the left and right sides that customers can use as they wish, but it has also been carefully designed to enhance a sense of togetherness connecting driver and passenger for a more pleasing and communicative driving experience. The rear door glass and quarter windows are positioned to enable rear seat occupants to view the scenery outside from a natural seated position, while the rounded space created by the doors, side trim and rear seats is designed to convey a feeling of being wrapped in reassuring comfort.
The luggage area is large enough to accommodate four (115cm) carry-on suitcases,1 realizing the space needed for use in a wide range of situations, from leisure to everyday use. There is also a sub-trunk beneath the floor that is convenient for storing small items. The height from the ground to the lower edge of the luggage area’s opening is designed in accordance with human characteristics to make loading and unloading luggage items easier. The space presents a clean look of quality and roominess, and care was taken with details such as minimizing the height difference between the luggage area and the rear seatbacks when they are folded down to make the space as easy to use as possible.
Power supply function
The MX-30 offers a rich set of power supply functions as it aims to support a variety of lifestyles. A pair of 2.5A USB ports and a 12V DC power socket are mounted on the front of the floor console as standard equipment. These power outlets make it easy to charge a smartphone, tablet or some other device. The model also includes a 150W AC outlet,1 making it possible to charge devices with larger batteries, such as notebook computers, e-mobility and drones.
Driving gets more enjoyable with every outing. Human-centric design delivers a pure driving experience in an electric vehicle.
Mazda has long challenged to deliver driving pleasure based on its Jinba-ittai driving experience. With the 2019 launch of the latest generation Mazda3, Mazda introduced Skyactiv-Vehicle Architecture, a set of new-generation structural technologies born of efforts to further evolve its human-centered development philosophy. As the third entry in Mazda’s new-generation car lineup, the MX-30 adopts this advanced technology, as well as its new e-Skyactiv electric-drive technology. As a result, the MX-30 realizes a pure driving experience that skillfully blends the dynamic performance and faithful response Mazda values so highly with smooth behavior and seamless operation. The MX-30 makes driving more enjoyable with every outing. The introduction of e-Skyactiv adds a new layer of depth to the driving pleasure derived from Mazda’s Jinba-ittai driving experience.
An ev that aims to deepen the Jinba-Ittai experience.
Jinba-ittai. It’s about the car and driver’s intention moving together as one, providing greater confidence, safety and faithful response. The desire to provide this Jinba-ittai driving experience led to the birth of technologies that leverage Mazda’s human-centric development philosophy to maximize the potential of human abilities. That’s how Mazda builds cars. Both the multi-directional ring structures of the body and G-vectoring control (GVC) were evolved to develop technology and fully exploit the characteristics and unique qualities of an EV. Mazda also developed its own unique motor pedal for the MX-30. These technologies realize seamless vehicle motion in all directions, composed ride quality coming from a feeling that the vehicle constantly gravitates toward the road surface, and an intuitive feeling of total control over all operations, including driving, turning and stopping, that makes such actions feel as though the car is an extension of driver’s body. The result is a further evolved expression of the Jinba-ittai driving experience.
E-Skyactiv electric-drive technology
Mazda developed new e-Skyactiv electric-drive technology to realize an EV that runs purely on electric power. By fusing a system that uses a lithium-ion battery pack and electric motor with technologies born of Mazda’s human-centric development philosophy, the MX-30 realizes a driving feel by which the car faithfully responds to the driver’s intentions.
The high-voltage components that comprise the e-Skyactiv system include the motor, battery pack, inverter, and DC-DC converter. The direct current from the battery is converted to alternating current by the inverter to drive the motor, while the DC-DC converter steps down the voltage to supply power to the car’s various 12V auxiliary equipment.
The motor, inverter, DC-DC converter and junction box are integrated into a single high-voltage unit that is mounted toward the front of the car. The size of the high-voltage battery mounted beneath the floor was carefully chosen to minimize CO2 emissions throughout its life cycle, from resource extraction through to battery disposal. To limit the height of the battery pack, it uses a high-density battery module and thin busbar wiring as part of a scheme that minimizes the size of wiring between high-voltage parts, as well as a thin cooling system. As a result, it minimizes the impact on interior space and helps secure roomy comfort in the cabin. As an additional measure, the battery case is joined to the body to effectively help increase overall rigidity. The normal and rapid charging ports are packaged as a set that is accessed from the right rear fender, with the onboard AC charger positioned in the luggage area.
Another feature is a control scheme that minimizes energy loss throughout the system, including loss from the inverter, the motor and in converting battery power into drive power. This combines with harmonious control between the system and the vehicle that reduces power consumption to maximize the amount of energy that goes directly toward powering the MX-30.
Battery cooling system
The MX-30 adopts a refrigerant cooling system that cools the battery pack when the temperature rises. By maintaining the best possible battery temperature even on hot days, the system helps protect the battery pack from degrading due to heat. Thin cooling tubes attached to the bottom plane of the battery module make contact with a heat exchanger. This structure contributes to realizing a compact battery pack. A sensor constantly monitors the battery’s temperature and controls the flow of coolant as needed. The result is an effective battery cooling system. Cooperative control between the air-conditioning and battery cooling systems achieves effective cooling performance for both systems.
Protective structure for the high-voltage components+
To prevent direct contact with the high-voltage components, the system adopts a cover and a control system that instantly shuts down power flow when it detects any irregularities. It also features a protective structure that protects the battery from external forces in the event of a collision, along with a mechanism to block off the high-voltage power. These measures prevent electric shocks in the event that an accident of some sort damages the high-voltage components.
The e-Skyactiv system can be charged using AC power or rapid-charged using DC power. The model supports DC charging with either the CHAdeMO or COMBO standard. Adopting the most appropriate standard for a specific region makes it possible to charge the MX-30 at any charging station in the world. AC charging of up to 6.6kW is also supported.
New-generation structural technologies: Skyactiv-vehicle architecture
Human beings have an amazing unconscious ability to control their legs, pelvis and spine in a way that balances their bodies and suppresses head sway when walking or running. To make it possible for people to tap into this natural ability in the car as well, Mazda worked to develop a human-centered design where the seats, body and chassis work together as an organic whole. This led to the birth of the new-generation structural technologies that comprise Skyactiv-Vehicle Architecture. The goal was to allow people a natural seating position that can be comfortably maintained while driving. Unflinching determination to pursue this goal led to creating a perfect fit with human sensibilities in terms of ride comfort and handling stability.
Toward this purpose, the MX-30 takes Mazda’s original body concept, which is based on straight framework bolstered by continuous ring structures, and enhances it by increasing its rigidity and energy transmission efficiency. The vertical, lateral and longitudinal connections of the body’s multi-directional ring structures increase rigidity while reducing lag in energy transmission and maximizing the function of the dampers and tires. By concentrating energy input from the road surface in specific locations and using the damping structure that serves as a buffer material to absorb it, the body effectively reduces vibration that would otherwise cause noise and does so without increasing vehicle weight. Incorporating the battery pack as a part of the body’s ring structure enhances the multi-directional ring structures of its basic design by greatly increasing diagonal rigidity. Specifically, the frame that surrounds the battery pack is connected to the body in 20 locations. Straight crossmembers sandwiching the battery pack from above and below combine with a reinforced ring structure for the rear axle mounts significantly reduces the delay in the transmission of inputs. Careful control over the rigidity of the battery pack mounts lets the MX-30 use the battery to help suppress road noise.
Skyactiv-vehicle dynamics new-generation control technologies. Electric G-Vectoring Control Plus (e-GVC Plus)
In the MX-30, Mazda’s G-Vectoring Control (GVC), which uses the powertrain to improve chassis performance, has evolved into e-GVC Plus, which leverages the torque characteristics of the electric motor to optimize the front-rear load shift under an even wider range of usage scenarios. In every speed range, the system achieves smooth and seamless transitions between longitudinal and latitudinal G-forces, whether the driver is making steering corrections on a straight roads or cornering. This provides vehicular behavior that always feels natural and pleasing.
e-GVC Plus provides fine control over motor torque in response to the driver’s steering wheel operations. When the driver turns the steering wheel to enter a corner, the system reduces torque slightly to instigate load transfer to the front and assume a smooth turning posture. When the driver starts to return the steering wheel to its original (neutral) position as the car begins to exit the corner, torque is increased slightly to shift the load to the rear and stabilize vehicle behavior. This also helps assist in quickly returning to straight-line travel. If the driver quickly returns the steering wheel to the neutral position, brake moment control that settles cornering behavior operates in cooperation. As a result, it greatly improves stability when driving on mountain roads, highways and slippery surfaces. These measures realize an EV that features incomparable handling performance.
The motor pedal for e-Skyactiv uses Mazda’s own electric motor torque control system to realize the desired vehicle speed and posture control based on the driver’s intended amount of acceleration or deceleration. It seamlessly connects forward and reverse torque and supports smooth fore-aft G-force control. Closely monitoring the stroke as well as the speed of the driver’s pedal action enables the pedal to meet the expectations of the driver in responding with linear application of G force. Gradual torque transition makes it easy to maintain vehicle speed when the driver operates the pedal slowly. In contrast, it interprets quick pedal operation as an indication that the driver wishes to accelerate and responds quickly by providing powerful acceleration. Following a similar scheme when lifting the foot from the pedal, the system monitors the speed with which the driver operates the pedal and controls the response of deceleration G force accordingly. Power unit mounts and other measures to increase the rigidity of the torque transmission system realize smooth and stable vehicle behavior, even as the motor torque changes from generating drive power to generating braking force. In addition, cooperative control over deceleration by the motor and brakes as the brake pedal is operated allows kinetic energy to be recovered and electricity regenerated without waste. Seamlessly connecting deceleration force as the driver moves his or her foot from the motor pedal and starts to press the brake pedal provides greater control over the front-rear load shift when stopping, maintaining a safe distance between the MX-30 and other vehicles, or when cornering.
Even though an EV produces no engine sound, Mazda’s e-Skyactiv provides aural feedback to the driver that enables him or her to subconsciously recognize the torque status of the power unit and thus control vehicle speed with greater precision. For example, when people hear the sound of a river flowing, they can imagine the amount of water and speed at which it is flowing based solely on the sound frequency and sound pressure. Mazda takes advantage of this human characteristic by actively controlling the sound through the audio system in a way that sounds natural and pleasing to the driver’s ears. Synchronizing the sound to perfectly match the motor torque makes it possible to supply the driver with feedback that precisely reflects the driving conditions and helps realize the control needed to satisfy the driver’s intentions.
Mazda’s ideal for braking performance is to have braking force build gently starting the instant the driver touches the brake pedal and then maintain a consistent strength level. Braking force should also drop off smoothly when gently lifting one’s foot from the pedal. Developed according to this same philosophy, the MX-30’s braking system reduces rolling resistance while increasing control. The resulting vehicle behavior enables cabin occupants to maximize their innate ability to maintain balance and enjoy a comfortable driving experience.
Safety performance designed for greater reassurance and to help realize an accident-free automotive society
Mazda Proactive Safety is the philosophy that guides all of Mazda’s safety performance research and development. With safety fundamentals such as driving position at its core, this philosophy drives ongoing efforts to continue evolving Mazda’s advanced i-Activsense active safety technologies and passive safety features. It of course applies equally and fully to the MX-30.
The MX-30 further evolves i-Activsense. One such evolution to the injury- and damage-mitigating brake system adds Turn-Across Traffic functionality to the existing Smart Brake Support (SBS) system to help prevent collisions when turning across traffic at intersections. The MX-30 also introduces new technologies, including Road Keep Assist, which helps keep the car on the right track even in the absence of lane markings and Emergency Lane Keeping with Blind Spot Assist, which helps prevent collisions when changing lanes. Adding these to the various safety technologies Mazda has developed and implemented to date expands coverage to apply to a wider range of driving scenes. On the passive safety front, despite the MX-30 adopting Mazda’s center-pillar-less Freestyle door system, rigid body and structures that efficiently absorb crash energy achieve a high level of collision safety performance.
Active Safety: I-Activsense. Smart Brake Support (SBS) with turn-across traffic.
SBS adds a new Turn-Across Traffic function to the vehicle, pedestrian, nighttime pedestrian and bicycle monitoring functions already built into the system. When turning left at an intersection, (on left-hand drive units), the forward-sensing camera and milliwave radar sensors monitor oncoming traffic. When the system determines there to be a chance of a collision occurring, it automatically applies the brakes to help prevent impact or mitigate damage that may occur. The function only operates at low speeds and is programmed to monitor nearby vehicles.
Emergency lane keeping
• Road keep assist - When travelling at speeds of approximately 60km/h or greater, the forward-sensing camera monitors grass, curbs and such along the edges of unmarked roads. When the system determines there to be a chance of the vehicle drifting off the road, it assists steering operations to prevent that from happening. This helps instill greater peace of mind when driving on roads without lane markings.
• Blind spot assist - The system uses 24GHz milliwave radar sensors to monitor the areas behind and to the sides of the car when travelling at speeds of 60km/h or greater. If the driver steers to change lanes when there is a threat of colliding with a vehicle approaching from the rear, the system assists steering operations to help prevent impact or mitigate damage that may occur.
Passive safety. Lightweight, high-rigidity body designed for safety.
To protect cabin occupants in the event a collision occurs, the MX-30’s center-pillar-less design incorporates a process by which hot-stamped material is first attached to the multifaceted reinforcing material before both are formed together into the A-pillar and roof side shapes. Extensive use of 1,310 MPa-class and other ultra-high-tensile steel combines with efficient energy-absorbing structures throughout. In addition, aiming to combine high-level collision safety with the Freestyle door system, hot-stamped vertical reinforcements are positioned inside the rear doors. The result is a structure that firmly receives impact energy from side collisions and effectively diffuses it out toward the body opening. Reinforcing of the front and rear hinges, as well as the side sills, has realized body strength and energy-absorbing efficiency on par with cars that have center pillars.
The MX-30 also adopts a safety system that shuts down the flow of power the instant a collision is detected. In addition, the battery packs are covered with high-strength material and surrounded by a rigid frame. This design offers the batteries solid protection, which in turn protects cabin occupants from potential secondary injuries caused by exposure to high-voltage power.
Mitsubishi Mi-Tech Concept
Mitsubishi Motors Corporation (MMC) today unveiled the Mi-Tech Concept small-sized electrified SUV concept car, Mi-Tech Concept at 2019 Tokyo Motor Show.
Takao Kato, chief executive officer, MMC, and Ashwani Gupta, chief operating officer, MMC, presented those vehicles at the press conference and explained MMC's electrification strategy.
"We are dedicated to electrification technology, particularly plug-in hybrids (PHEVs)," Kato said. "We will be expanding our lineup of electrified vehicles by delivering more variations and leveraging the diverse electrification technology in the alliance to make MMC the leader in the PHEV category going forward."
Overview of Mi-Tech Concept
The Mi-Tech Concept was built to be "small plug-in hybrid electric SUV that delivers unparalleled driving pleasure and confidence over all terrain in light and wind." This concept car embodies the MMC brand statement "Drive Your Ambition" with a lightweight, compact, new PHEV drivetrain, a four-motor electric 4WD system, and advanced driver assist and preventive safety technologies—all packed into the small-sized electrified SUV.
Dynamic Buggy Type Design
Under the concept of "Stimulates the driver's adventure", the Mi-Tech Concept is designed to be a dynamic buggy-type vehicle that embodies the very essence of Mitsubishi-ness.
A sense of progressiveness as an electric vehicle is expressed through the light blue body color and a secondary copper color in a motor coil motif on the grille, inner wheels, and interior.
The front end adopts MMC's signature Dynamic Shield new front design concept. It uses a satin plated color in the center of the grille, and copper as a secondary color to accentuate its expressiveness as an electrified vehicle. T-shaped headlights are embedded in the front end to emphasize a distinguishing outward appearance.
On the lower bumper, aluminum skid plate is placed on both sides to protect the body, while the interior has an air intake.
On the sides, the highly raised overfenders and large diameter tires project a high level of mobility plus power as an SUV, as well as the stability to thoroughly grip the terrain. The body radiates grandeur and sharpness with a design reminiscent of a metal ingot carved in a cutting machine, while the use of a side step on the carved sides balances utility with design.
The rear-end was designed with large and bold hexagon carved from metal ingot to emphasize the robustness of SUV. The T-shaped tail lamp shared the same design pattern used on the front end.
Inside, a horizontal instrument panel and functional design makes handling easier. The horizontal theme is further accentuated by copper lines added on the instrument panel and steering wheel. Keyboard-shaped switches are positioned atop a center console with a horizontal theme, and the front handgrip also functions as a hand pad to make the switches easy to operate. Functions are presented in a straightforward manner, easy to understand just by seeing them and with a reassuring feel when pressed.
MMC emphasizes a design that gives driver extra peace of mind. The front window shield presents all the relevant information in graphics such as car behavior, terrain recognition, and optimal route guidance.
Light, compact PHEV drivetrain
The power generator in the new PHEV drivetrain is a lightweight, compact gas turbine engine-generator in place of the traditional gasoline engine. As environmental awareness grows and downsizing progresses, the concept explores the technological proposition to plug the PHEV drivetrain into a small SUV. The gas turbine engine-generator has a powerful output for its size and weight.
Another benefit of the gas turbine is its flexibility to run on a variety of fuels such as diesel, kerosene and alcohol which can be selected depending on the regions. Further, its exhaust is clean so it responds to environmental and energy issues.
Electric 4WD system
MMC took pride to apply its S-AWC Integrated Vehicle Dynamics Control System to a Quad Motor 4WD System with front and rear Dual-Motor Active Yaw Control (AYC) units. Making the brake calipers electric has also allowed for high response, high accuracy control of drive and braking force of the four wheels while delivering a drastic improvement in turning and traction performance. When driving off-road and two wheels are spinning out, the ability to transmit the optimal driving force to all four wheels makes it possible to transmit force to the two wheels still on the ground and keep driving. MMC has thus delivered a safe, exhilarating driving experience in which the driver feels with the vehicle in all conditions, either in daily driving or when traversing rough roads, while also allowing for thrilling new driving experiences such as 180-degree spins by counter-rotating the left and right tires.
Advanced driver assistance and preventive safety technologies
The vehicle comes equipped with Human Machine Interface (HMI) which displays various information detected through sensing technology including advanced optical sensors on an augmented reality (AR) windshield. With vehicle, road, and surrounding traffic conditions shown on the AR windshield, drivers can make accurate, heads-up decisions even in poor visibility.
Equipped also with Mi-Pilot, next-generation driver assistance technology, the concept car extends driver support not only on freeways and ordinary roads, but also on unpaved roads.
