Accelerating Efforts to Make Ever-Better Motorsports-Bred Cars and Achieving a Carbon-Neutral Society.

Today the Toyota Motor Corporation (Toyota) announced its team setup, as well as efforts in producing, transporting and using hydrogen and carbon-neutral fuel, for the ENEOS Super Taikyu Series 2022 Powered by Hankook Round 1 Suzuka 5-Hour Endurance Race (Suzuka 5-Hour Race), which takes place from March 19 to 20, 2022.

This year, Toyota will enter three vehicles equipped with powertrains that use different fuels in the Super Taikyu Series. We aim to achieve a carbon-neutral society while promoting the making of ever-better motorsports-bred cars by refining vehicles and solving issues in an agile manner in the field of motorsports. In collaboration with other industries, we will also continue to promote the generation of new partners in producing, transporting, and using hydrogen and carbon-neutral fuel.

In addition, we aim to contribute not only to motorsports but also to social development and future life through cooperation with the Super Taikyu Organization and Super Taikyu Series 2022 main sponsor ENEOS Corporation , as well as other Super Taikyu sponsoring and operating companies and related organizations.

Goals of the three vehicles entering the Super Taikyu Series 2022

Hydrogen engine-equipped Corolla

The hydrogen engine-equipped Corolla competed in a total of four rounds in last year’s Super Taikyu Series, promoting agile development through motorsports. In the approximate six months between the first round in May of last year and the final round in November, engine performance was improved to levels comparable to gasoline engines, with a 24% increase in power output and 33% increase in torque, along with successful control over abnormal combustion. However, improved cruising range and reduced hydrogen filling time for practical use are major issues that will be addressed throughout the year.

GR86 (carbon-neutral fuel)

Starting this year, we will enter a new GR86-based vehicle that uses carbon-neutral fuel as an attempt to expand internal combustion engine fuel options. The vehicle will be powered by a 1.4-liter turbo engine developed from the GR Yaris engine and the hydrogen engine-equipped Corolla, and development will be promoted using technology on hand.

Carbon-neutral fuel has been attracting attention as a means of achieving carbon neutrality. The reason for this is that while carbon dioxide is emitted during combustion, the fuel itself uses carbon dioxide present in the atmosphere which results in plus/minus zero emissions, as well as the fact that it can use existing infrastructure and vehicle technology. Though competing throughout this year with Subaru Corporation, another ST-Q class competitor, and by training in the field of motorsports, we will discover issues, make improvements, and explore the possibility of future practical applications. In addition, the knowledge gained through refining the vehicle during races will be applied to the evolution of the Subaru BRZ and GR86.

GR86 (gasoline)

We will enter a vehicle based on the GR86 from Round 2, the FUJI SUPER TEC 24-Hour Race under the banner of TOM’S SPIRIT. Closer to a production car than the GR86 (carbon-neutral fuel) competing in the ST-Q class, it will be refined through races and we will apply the findings to develop production models and parts, promoting the making of ever-better motorsports-bred cars. We also hope to contribute to the overall excitement of the ST-4 class through a friendly rivalry with other teams.

Producing

In addition to solar power-derived hydrogen from Namie Town (FH2R) in Fukushima Prefecture, the hydrogen engine-powered Corolla will use a supply of hydrogen derived from solar power generation produced in cooperation between Yamanashi Prefecture, Tokyo Electric Power Company Holdings, Inc., and Toray Industries, Inc.

The Yamanashi Prefecture, Tokyo Electric HD, and Toray produced hydrogen is currently used in factories in Yamanashi Prefecture. Up to 370 Nm3 of hydrogen is produced per hour by electrolyzing water with electricity derived from solar power through a P2G (power-to-gas) system at the Komekurayama Electric Power Storage Technology Research Site in Kofu, Yamanashi Prefecture. Yamanashi Prefecture established the Yamanashi Hydrogen Company, Inc., the first in Japan to specialize in P2G systems, in February together with Tokyo Electric HD and Toray to promote the development of this P2G system in Japan and abroad and to promote the creation of a hydrogen energy society. It focuses not only on the technological development of P2G systems, but also on sales activities.

Transporting

Hydrogen for the hydrogen engine-equipped Corolla will be transported to the Suzuka Circuit in the bio-fuel trailers of Toyota Transportation Co., Ltd, and the electric fuel cell trucks of Commercial Japan Partnership Technologies. Until now, we have used metal tank in hydrogen transportation, but going forward, CJPT’s fuel cell electric trucks will use racks tanks mounted with lightweight resin liners cultivated in the development of the FCEV MIRAI, enabling high pressure hydrogen transport. By changing current tank to those with resin liners, tank pressure can be increased from 20 MPa to 45 MPa, and the amount of hydrogen that can be transported has increased by approximately four times compared to the previous race. In addition, we will continue to make improvements to meet the demands of those who need hydrogen in various fields, such as by raising the tank pressure to 70 MPa, and take on the challenge of transporting hydrogen even more efficiently.

Using

We will take on the following issues of the hydrogen engine-equipped Corolla at the Suzuka 5-Hour Endurance Race: (1) Cruising range improvement, and (2) hydrogen filling time reduction.

Cruising range improvement

We can control abnormal combustion by precisely controlling fuel injection and use hydrogen in the tank more efficiently. As a result, the possible driving distance on a single hydrogen fill-up has been improved by 20% since the last race. In addition, seeking to improve cruising range even further, we have started to take on the challenge of developing a new technology that can convert currently used gaseous hydrogen into liquid hydrogen. If this is eventually achieved, the improved energy density per volume will not only make it possible to greatly extend cruising distance, but also expand the options for the state of hydrogen that can be used.

Hydrogen filling time reduction

Last year, we made improvements to the vehicle to allow for filling from both sides, and reduced hydrogen filling times with each round. This year, with an eye on expanding the use of hydrogen in the future, we will take on the challenge of “high flow filling,” increasing boosting the rate of pressure during filling. Normally, the temperature inside the tank increases rapidly if filled all at once, but we have changed the filling port and piping to handle large flow rates while ensuring safety to make sure the upper temperature limit isn’t reached. By using high flow filling while maintaining the method of filling on both sides of the hydrogen engine-equipped Corolla, hydrogen filling time has been shortened from just under two minutes in the previous race to one and a half minutes.

In the ST-Q class, in addition to the hydrogen engine-equipped Corolla and GR86 (carbon-neutral fuel), Mazda Motor Corporation’s MAZDA SPIRIT RACING Bio concept DEMIO and Subaru’s Team SDA Engineering BRZ CNF Concept will also participate in the rounds using carbon-neutral fuel. The three companies will exchange information in areas of cooperation while still competing against each other during the race, increasing technological research speed and striving to achieve a carbon-neutral society.

Toyota will continue to work together with many relevant parties to refine vehicles and accelerate development in the strict environment of motorsports, create a wide range of partnerships beyond the boundaries of the industry, and further expand options for producing, transporting, and using hydrogen and carbon-neutral fuels to help achieve a better carbon-neutral society.
