Super GT is introducing a new, carbon-neutral fuel for the 2023 season. All the cars in the series will use this fuel called GTA R100. On Monday, the day after the 2022 season finale, Super GT tested this fuel at Motegi. The 22 cars which used the new fuel showed little to no difference in performance. However, there were two strange issues created by the sustainable fuel's exhaust fumes: a strange smell and eye irritation.
Some drivers who raced in the Super GT noticed that the exhaust fumes from the cars using GTA R100 fuel had a strange smell. However, some drivers experienced eye irritation while following other cars around the circuit. According to Honda SUPER GT project leader Masahiro Saiki, the problems result from fuel that doesn't fully combust. Most likely, the solution before next season will entail using different ingredients in the fuel mixture to guarantee a complete burn.
According to ETS Racing, the Renewablaze GTA R100 fuel is produced from a number of different sources of sustainable biomass and consists of 100 percent plant-based raw materials. The feedstock is derived from cellulosic material that is converted into hydrocarbons and oxygenates.
ETS Racing Fuel currently produces it's fuel at sites in Germany and US. Super GT expects to race with carbon-neutral fuel produced domestically in Japan by 2027 after four seasons with imported fuel.
