The FIA has granted no additional Formula 1 power unit homologations following its third performance review of 2026, covering races 12 to 18 through the United States Grand Prix. The governing body said the gaps between internal combustion engines had changed, but those changes did not lead to extra allowances.
The Additional Development and Upgrade Opportunities system allows manufacturers whose engines are at least 2% behind the leading engine over a review period to receive additional homologated upgrades, as well as extra cost cap and dynamometer testing allowances. The FIA said the individual performance measurements remain confidential.
After the first review, Mercedes was placed in the 2–4% band and allowed one additional homologation in each of 2026 and 2027. Audi, Ferrari and Honda were assessed as more than 4% behind and allowed two in each year. The second review produced no additional homologations.
The FIA said its next review period will cover the first six races of 2027, from Bahrain to Miami.
