Toyota Motor Corporation has been very outspoken about its efforts in producing, transporting, and using hydrogen and carbon-neutral fuel. For this year’s ENEOS Super Taikyu Series, Toyota is racing three vehicles equipped with powertrains that use different fuels. The 2022 Super Taikyu Series team setup includes a hydrogen engine-equipped Corolla, a carbon-neutral fuelled GR86 and a race gasoline GR86.
The hydrogen engine-equipped Corolla competed in four rounds in 2021’s Super Taikyu Series, promoting the development motorsport brings to technology. 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 still significant issues to address throughout this year. Also starting this year is a new GR86-based race car that uses carbon-neutral fuel as an attempt to expand internal combustion engine fuel options. The vehicle is powered by a turbocharged 1.4-litre engine developed from the GR Yaris engine and the hydrogen engine-equipped Corolla. The development will be done using contemporary technology rather than new innovations.
