Petronas Secures F1 Fuel Homologation for Mercedes Ahead of 2026

Mercedes Formula 1 team has cleared a major regulatory hurdle ahead of the 2026 season opener, with its long-time fuel supplier Petronas securing homologation for the new sustainable fuel just days before the Australian Grand Prix in Melbourne.

The development resolves lingering uncertainties that surfaced during winter testing in Bahrain and Barcelona, where it became clear that not all fuel suppliers had completed the certification process. Without homologation, the teams risked having to switch to an alternative compliant fuel, potentially compromising engine performance.

The homologation process for 2026 introduces stricter standards aligned with Formula 1's shift to fully sustainable fuels, alongside chassis and power unit overhauls, 50 percent electrification, and active aerodynamics. Unlike previous years, where certification involved sending samples to an FIA-affiliated lab for chemical analysis—typically taking about 20 days—the new rules require end-to-end verification...
