With two preseason testing sessions complete, the season is already shaping up to be a decisive one; however, there could be a major setback for the Mercedes-powered teams.

The 2026 Formula 1 season kicks off in just under a month at the Australian Grand Prix, however, some teams might have already hit a brick wall.

It is rumoured that Petronas, whose sustainable fuel is used for all Mercedes-powered teams, are in a race against time to obtain certification and homologation.

From this season onwards, Formula 1 teams must use fuel that is not derived from fossil fuels. When outlining the new regulations, the FIA explained, "The increase in electrical energy is just one element of a major FIA move towards a more sustainable Formula 1, and from 2026 all F1 cars will use advanced sustainable fuels."

"The FIA has mandated the use of sustainable fuel derived from 'Advanced Sustainable Components' (ASCs), ensuring they are sourced from non-food biomass, renewable feedstock of non-biological origin or municipal waste, and meet stringent greenhouse gas emissions thresholds."

What does that mean for the other teams?

With Petronas still waiting for the lengthy procedure of certification and homologation, it means Mercedes, McLaren, Williams and Alpine will all have a nervous wait.

If Petronas does not obtain approval in time for the Australian Grand Prix on March 8, the teams may have to use temporary fuel for the first race, which has not been developed in harmony with their engine production.

This year, the FIA has outsourced fuel certification to Zemo. The British-based company oversees the approval and production process.

All 11 teams will still be able to complete the second round of preseason testing in Bahrain, as it is not a requirement to use sustainable fuels for the tests. However, at this time, little more is known about the temporary fuel or what the teams will do if they fail to secure homologation in time for the Australian Grand Prix.
