batteries will start with batteries for HEVS, which
we have been developing for years and require a
small battery volume, rather than building a
massive production line for batteries for BEVS,
which require a larger volume of batteries. This will
not only enable us to accelerate the release of the
products but also position us to better focus on
improving manufacturing technologies. Moreover,
Toyota's strategy of "starting up using small basic
units" is also meant to enable the Company to
swiftly respond to the ever-changing stages of the
product cycle, in which new technologies arrive as
the manufacturing costs for older models come
down and stabilize.
Effective Reduction of CO2 Emissions
with Few Batteries
Since the introduction of the first-generation Prius
in 1997, Toyota has introduced PHEVS, FCEVS,
and BEVS while continuing to improve their perfor-
mance. Our more than 20 years of producing HEVS
have resulted in cumulative sales reaching 19.8
million units as of March 2022.

According to a Toyota estimate, the CO2 emis-
sions reduction effect of three HEVS is equivalent to
the reduction effect of one BEV. Accordingly,
Toyota's HEVS sold to date achieve a CO2 reduc-
tion effect equivalent to about 6.0 million BEVS. The
volume of batteries for HEVs that we have pro-
duced thus far is the same as that of the batteries
for about 280,000 BEVs. In other words, we can
say that the batteries needed for 280,000 BEVS
have been used to achieve the CO2 emissions
reduction effect of 6.0 million BEVS.
Providing the Fuel Cell System of the
Second-generation Mirai Globally
In the field of fuel cell electric vehicles (FCEVS), we
released the completely redesigned Mirai in
December 2020. Premised on the use of an FCEV
system, the second-generation Mirai was devel-
oped with the goal of delivering a futuristic premi-
um car that would be genuinely appreciated and
sought after by our customers. Specifically, we
strove to deliver a vehicle that could win drivers'
hearts during and after driving, if not from the

moment they first catch sight of it.
Moreover, Toyota aims to become a fuel cell
(FC) system supplier supporting the realization of
a hydrogen-powered society. In line with this aim,
we provide a variety of business operators with a
compact FC system module package that we
have developed. This package consists of FC
stacks for the second-generation Mirai, which
boast higher performance, as well as air supply,
hydrogen supply, cooling, power control, and
other FC system-related parts.
In North America, we have unveiled a new
prototype for an FC commercial heavy-duty truck
that uses the second-generation FC system
installed on the new Mirai. This truck boasts
considerably improved performance, including
more powerful acceleration and flexible driving
response. Furthermore, having attained a maxi-
mum loaded weight of 80,000 pounds (approxi-
mately 36 tons) and a cruising range of 300 miles
(more than 480 kilometers), the truck is designed
to accommodate a wide range of commercial
truck needs. We will conduct the verification
testing of this new FC truck in actual cargo
transport operations.

Utilizing e-Fuel Made from Hydrogen
To achieving carbon neutrality, we are also
considering a revolutionary approach expected
to drastically curb CO2 emissions through the
combination of such carbon-neutral fuels as
biofuel and e-Fuel made from hydrogen with
high-efficiency engine and motor technologies.
Not only is the above approach practicable via
the use of existing infrastructure, it could help us
reduce CO2 emissions from all types of vehicles
currently in use.
For example, when gasoline vehicles are fed
gasoline mixed with a certain amount of e-Fuel,
their CO2 emissions decline to a level on par with
emissions from HEVS. The mix of e-Fuel in gaso-
line will similarly curb the CO2 emissions from
HEVS to a level on par with PHEVs, and emissions
from PHEVS to closer to the level of BEVS.
Development of an FC System for
Maritime Applications
Toyota is applying its FC technologies for
maritime applications and provides them to
Energy Observer Developments (EODev).
Headquartered in France, EODev is a com-
pany that conducts research on renewable
energy. By conducting trials in demanding
marine environments that vary by location,
EODev continues to probe the possibilities
of renewable energy.
In February 2020, EODev's ship Energy
Observer carried out testing of a Toyota FC
system at sea. In October 2020, we
announced the use of Toyota FC modules
on a pleasure boat, as well.
