Red Bull shut out again in FIA engine review
The FIA's second ADUO review confirmed Red Bull Ford as the benchmark, with Mercedes 2-4% behind and Ferrari, Audi, and Honda over 4% behind. No new homologation opportunities were awarded, leaving Red Bull unable to access catch-up provisions. Mercedes retains its 2026-2027 upgrades and additional resources based on its deficit. The FIA defended its methodology, noting Honda's recent updates were not included in the assessment.
