Il Presidente di
Toyota Motor Corporation Akio Toyoda, ha consegnato la prima Mirai al Primo Ministro Giapponese Shinzo Abe.
Durante la cerimonia, Akio Toyoda ha affermato: “La consegna
della prima vettura al mondo equipaggiata con un sistema di celle a
combustibile, prodotta in serie,
segna l’inizio dell’era
dell’idrogeno: sono molto entusiasta. Sarà
un lungo percorso
e, per rendere
questo momento davvero storico,
sarà necessario collaborare a più
livelli, un costruttore da solo non può riuscirci.”
Questo messaggio
rafforza l’impegno di Toyota per lo sviluppo di una mobilità sostenibile
che integri l’idrogeno
tra le fonti di alimentazione.
Impegno testimoniato dalla
recente apertura all’utilizzo
fino al 2020 di circa 5.680
brevetti depositati da Toyota, tra i quali 70 relativi allo sviluppo di
stazioni di rifornimento dell’idrogeno.
Dopo aver provato Mirai, anche il Primo Ministro
Abe ha commentato: “Questo momento segna l’inizio
dell’era dell’idrogeno. Continueremo a focalizzarci sia sullo sviluppo tecnologico che sulle normative ed abbiamo
già eliminato alcune restrizioni.
Lavoreremo anche per
lo sviluppo di
una rete distributiva
sia per il carburante tradizionale che per
l’idrogeno”. Nel suo discorso, il Primo Ministro Abe ha anche invitato tutte le
Agenzie Governative ad utilizzare Mirai
che oggi, ad un solo mese
dal lancio, ha raggiunto 1.500 ordini, il 60% dei quali da
parte di uffici governativi ed aziende.
Mirai ha il potenziale per accelerare ulteriormente la
diversificazione delle fonti di alimentazione e contribuire a sviluppare una
società che utilizza anche questa nuova
risorsa, combinando ottime performance di guida ed un rispetto per l’ambiente senza
precedenti.
The Mirai uses the
Toyota Fuel Cell System (TFCS), which features both fuel cell technology
and hybrid technology, and includes Toyota's new proprietary FC Stack and
high-pressure hydrogen tanks. The TFCS is more energy efficient than internal
combustion engines and emits no CO2 or substances of concern (SOCs) when
driven. Drivers can also expect the
same level of convenience as offered by gasoline engine vehicles, with a
generous cruising range and a hydrogen refueling time of about three minutes3.
The Mirai delivers everything expected of a next-generation
car: an immediately recognizable design; driving exhilaration stemming from
superior handling stability achieved by a low center of gravity; and quiet but
powerful acceleration provided by the electric motor. The Mirai also features
an exclusive telematics service for a safe, secure and comfortable ride, and
the vehicle can double as a high-capacity external power supply system during
power outages, disasters and other emergencies.
Hydrogen can be
generated using a wide range of natural resources and man-made byproducts
such as sewage sludge. It can also be created from water using natural
renewable energy sources like solar and wind power. When compressed, it has a
higher energy density than batteries, and is relatively easy to store and
transport, therefore it also carries expectations for potential future use in
power generation and a wide range of other applications. FCVs are able to
generate their own electricity from hydrogen, meaning they can help make a future
hydrogen-based society a reality, and are therefore expected to further
contribute to accelerating energy diversification.

TFCS provides
superior environmental performance and convenience
The Mirai features the TFCS, a fusion of fuel cell
technology with hybrid technology.
The system provides better energy efficiency than internal
combustion engines, superior environmental performance with no emissions of CO2
or SOCs when driving, and the same level of convenience as gasoline engine
vehicles with a cruising range4 of 650 km (according to Toyota measurements
taken based on the Japanese Ministry of Land, Infrastructure, Transport and
Tourism's JC08 test cycle) and a hydrogen refueling time of about three
minutes3.
The system uses Toyota-developed components including the
Toyota FC Stack, FC boost converter, and high-pressure hydrogen tanks.
Toyota FC Stack
The new Toyota FC Stack achieves a maximum output of 114 kW.
Electricity generation efficiency has been enhanced through the use of 3D fine
mesh flow channels5 (a world first6), which ensure uniform generation of
electricity on cell surfaces, providing compact size and a high level of
performance, and a world-leading6 power output density of 3.1 kW/L (2.2 times
higher than that of the previous Toyota FCHV-adv limited-lease model).
The amount of water on fuel cell electrolyte membranes has a
substantial influence on electricity generation efficiency. Control of the
amount of water is carried out using an internal circulation system for
circulating the water created when generating electricity, meaning the Toyota
FC Stack is a world-leading6 system that, unlike systems used in all other
previous Toyota fuel cell vehicles, does not require the use of a humidifier.
FC Boost Converter
A new compact, high-efficiency, high-capacity converter has
been developed to boost power generated in the Toyota FC Stack to 650 volts.
Increasing the voltage has made it possible to reduce the size of the electric
motor and the number of Toyota FC Stack fuel cells, leading to a smaller,
higher-performance Toyota Fuel Cell System, thereby reducing system costs.
High-pressure
Hydrogen Tanks
Tanks with a three-layer structure made of carbon
fiber-reinforced plastic and other materials are used to store hydrogen at a
very high pressure of 70 MPa (70 megapascals, or approximately 700 bars).
Compared to the high pressure hydrogen tanks used in the Toyota FCHV-adv model,
tank storage has been increased by approximately 20 percent while both weight
and size have been reduced to achieve a world-leading6 5.7 wt%7.
Safe and secure
vehicle design with comprehensive range of safety features
FCV safety measures
The Mirai was designed with safety as a top priority, based
on the basic approach of ensuring that hydrogen does not leak, and in the
unlikely event that any leaks do occur, ensuring immediate detection and
stoppage of hydrogen flow and preventing accumulation of hydrogen within the
car body.
* Development of high pressure hydrogen tanks with excellent
hydrogen permeation prevention performance, strength, and durability
* Hydrogen sensors provide warnings and can shut off tank
main stop valves
* Hydrogen tanks and other hydrogen-related parts are
located outside the cabin to ensure that if hydrogen leaks, it will dissipate
easily
Use of features such as a structure that efficiently
disperses and absorbs impact energy across multiple parts ensures a high impact
safety performance that protects the Toyota FC Stack and high-pressure hydrogen
tanks during frontal, side or rear impacts.
The Toyota FC Stack frame is constructed from a
newly-developed thermoplastic carbon fiber-reinforced plastic, which is light,
strong, and easily mass-produced. This protects the Toyota FC Stack by
absorbing impact shocks from road bumps and other road interference.
A full range of advanced safety equipment appropriate for
next-generation vehicles
* Standard inclusion of advanced safety technologies
* A Pre-collision System (with millimeter-wave radar) helps
prevent collisions or reduce collision damage through alerts and brake control
if a high likelihood of collision is detected.
* A Lane Departure Alert system uses a camera to detect
white or yellow lane markings and alerts the driver when the vehicle is about
to deviate from its lane.
* Drive-start Control limits sudden starts or sudden
acceleration during gear-shift operation.
* A Blind Spot Monitor uses radar to detect vehicles in
adjacent lanes and helps rear view confirmation when changing lanes.
Mirai's connective
services contribute to safer driving
The T-Connect Data Communication Module (DCM) package comes
with additional exclusive support functionality8 to ensure a safe, secure and
comfortable ride.
* The "Hydrogen Station List" a specialized app9
service, uses the navigation system screen to display information and current
operation status of the three closest hydrogen stations based on the location
of the car.
* "Pocket Mirai", an exclusive smartphone
application, displays information and current operation status of hydrogen
stations nationwide, the vehicle's remaining hydrogen fuel, possible cruising
distance, and possible external power supply time. It also includes a hydrogen
refueling record function and a game function that enhances driving pleasure.
* The FC system remote monitoring service displays a warning
notification on the navigation system screen if it detects a system
abnormality, and also includes a remote diagnostics support system that allows
the vehicle to be checked from a terminal at the dealer and the driver to be
given appropriate advice if the dealer is contacted by the driver.
3. Mirai's immediately recognizable design
Exterior
A new technique has been employed in the front face design
to emphasize the left and right grilles that draw in air for the oxygen supply
and for FC system cooling. The novel front face underscores the vehicle's
individuality.
The elegant side profile evokes the flowing shape of a
droplet of water to express the vehicle's characteristic of drawing in air and
emitting water. The roof-side rails and hood appear to pop out of the body to
create the impression of a low-to-the-ground vehicle while communicating a
futuristic feeling.
The rear of the vehicle presents a bold profile with a
trapezoidal shape extending from the license plate garnish to the bottom of the
bumper corners and out toward the wheels, while the top of the bumper
emphasizes width and expresses a powerfully stable stance. It also creates an
agile and clean impression of air passing through and under the bumper.
The headlights exhibit high-tech and sophisticated luxury
through a novel design that presents an ultra-thin profile with an inline
arrangement of four LED lights plus visible heat sinks and other optical
equipment. The front turn signals and clearance lights are separate from the
headlights, contributing to an ultra-thin headlight profile at the same time as
merging with the side grilles. This creates an advanced clean design with
aerodynamics that improve airflow.
The Mirai comes with 17-inch aluminum wheels that have been
made lighter using an engraving process10.
Six body colors are
available, including the new two-tone Pure Blue Metallic11.
Interior
The Mirai's profile connects the front and rear in a
seamlessly pleasant expression of space. It creates a sophisticated cabin space
with soft padding on door trims and other interior surfaces, and a
high-luminance silver finish throughout.
The front seats provide superior body fit and hold through
an integrated cover/seat foaming production process12. Eight-way adjustable
power seats for achieving the optimal seat position and a motorized lumbar
support function are installed as standard on the driver's and passenger's
seats.
The center meter cluster located in the central top level of
the instrument panel includes a speedometer and multi-information display using
a 4.2-inch high-definition TFT liquid crystal display with a design that
appears to pop out. The driver is able to change the display using
steering-wheel-mounted controls.
Seat heater switches and other controls are operated via an
electrostatic air conditioning control panel by lightly touching the flat panel
display.
Functions that provide a comfortable interior space come as
standard, such as a steering wheel heater and seat heaters (two temperature
settings on all seats) that provide instant heat while greatly reducing power
consumption, fully automatic left and right independent temperature control air
conditioning with eco mode switches, and "Nanoe"13 air purification technology
to fill the cabin with fresh air.
Three interior colors are available, including Warm White.
Package
Battery layout enables abundant trunk storage space. 4.
Superior handling stability and outstanding quietness enhances driving pleasure
The high output Toyota FC Stack and optimal battery power
control drive the electric motor and ensure powerful responsiveness at all
vehicle speeds. This provides an immediate increase in torque at the first
press of the accelerator, and powerful and smooth acceleration thereafter.
Handling stability and ride comfort are both improved
through the location of major parts such as the Toyota FC Stack and high
pressure hydrogen tanks centrally under the floor to achieve a low center of
gravity and superior front-and-rear weight distribution, as well as the use of
a high-rigidity body, which features enhanced rigidity around the rear
suspension.
The full under-floor cover and aerodynamically designed
clearance lights reduce wind resistance and contribute to improved fuel efficiency
and handling stability. Aero fins employed at the side of the rear combination
lamps also improve straight-driving stability.
Outstanding quietness is achieved by electric motor drive at
all speeds and reduced wind noise, plus full sealing of all body parts, and the
use of sound-absorbing and sound-blocking materials optimally arranged around
the cabin, including the use of noise-reducing glass for the windshield and all
door windows.
Brake support mode makes efficient use of regenerative
braking and improves braking performance when the driver wishes to greatly
reduce vehicle speed such as when negotiating long downhill sections of road.
5. Large external
power supply system
The Mirai comes with a power supply system with a large
capacity of approximately 60 kWh14 and maximum power supply capability of 9
kW15 for use during power outages, such as those following natural disasters.
When a power supply unit (sold separately) is connected, it converts the DC
power from the CHAdeMO power socket located inside the trunk to AC power and
can power a vehicle-to-home16 system or a vehicle-to-load system. Consumer
electronics can also be connected directly and used from the interior accessory
socket (AC 100 V, 1,500 W).
