"Taking on the challenge of racing in the Super Taikyu Series next year using biomass-derived synthetic fuel (Subaru and Toyota)
Toward the achievement of carbon neutrality, Subaru and Toyota are promoting efforts that include vehicle electrification, such as by introducing the jointly developed Subaru Solterra and Toyota bZ4X BEVs, which are scheduled for global launches in mid-2022.
To study new options, the two companies plan to enter and conduct verification tests of two new vehicles powered by carbon-neutral synthetic fuel derived from biomass in the ST-Q class of the 2022 season of the Super Taikyu Series. Specifically, Subaru intends to race in a Subaru BRZ-based vehicle and Toyota in a Toyota GR86-based vehicle. By collaborating and competing together in racing, the two companies plan to accelerate the development of technologies for all options and take on the challenge of achieving carbon neutrality."
