Racing fuel in all Grand Prix classes will be of 100% non-fossil origin from 2027, as confirmed by the Grand Prix Commission. The C14 test will be used to assess all fuel used in MotoGP and related racing classes.
The C14 test measures the fraction of the short-lived carbon isotope C14, which is not found in fossil fuels due to its long carbon decay period. The test then compares it to the standard C14 levels found in the atmosphere.
For 2027, fuels used in MotoGP should have the same numbers minus a tolerance, meaning the C14 content of the fuel sample should be the same as the atmosphere. This eliminates the possibility of the fuel being of fossil origin.
Fuels will therefore no longer be obtained by means of crude oil refinement. Fuels used in MotoGP maybe either; bio-fuels i.e. fuels obtained from bio sources, or; e-fuels obtained by direct atmosphere CO2-capturing.
Burning this combinations of non-fossil fuels releases the same amount of carbon that existed before being captured, i.e. the fuel is carbon-neutral. Since 2024, MotoGP has mandated fuels contain at least 40% non-fossil content when used for racing, predominantly derived from crude oil refinement.
