F1 teams have been allowed to run non-homologated fuel in 2026 pre-season testing – but why?
Allowing Formula 1 teams to use non-homologated fuels during pre-season testing, which are not permitted on race weekends, has sparked interest recently due to an unintended regulation loophole. The complexity of introducing sustainable fuels by 2026 led to this pragmatic decision by the authorities. Reports questioning the legality of Mercedes’ Petronas fuel were vehemently dismissed by team principal Toto Wolff as “nonsense.” Teams like Mercedes are using a ‘surrogate’ fuel in testing, similar to race fuel but with components from outside the sustainable supply chain. This temporary allowance will not continue after this year’s testing. The FIA’s aim is for all fuels to be certified before racing, but there might be a delay due to the intricate process. Overall, this adjustment was made to facilitate testing while ensuring compliance with future sustainability goals.
