FIA announce crucial final ADUO results as upgrade plans for every F1 team revealed

The FIA has revealed the results of its third Additional Development and Upgrade Opportunities (ADUO) review for the 2026 Formula 1 season, which covers races 12 through 18. Red Bull Powertrains was designated as the benchmark power unit, receiving zero in-season upgrade opportunities. Mercedes was evaluated as trailing by 2-4 percent, earning one upgrade opportunity for both 2026 and 2027.

Ferrari, Audi, and Honda were each assessed as trailing by more than four percent, granting them two upgrade opportunities each across 2026 and 2027. The ADUO system evaluates only the Internal Combustion Engine to aid parity under the 2026 regulations, and FIA single-seater director Nikolas Tombazis confirmed the governing body remains confident in the findings.
