FIA reveals findings of final F1 ADUO window

The FIA has revealed the results of the third and final Additional Development and Upgrade Opportunities (ADUO) window of the Formula 1 season. According to a statement provided to Motorsport Week, the governing body confirmed that no additional homologations were granted to any power unit manufacturers, as the evolving performance gaps did not trigger the required thresholds.

Under this season's new regulations, manufacturers lagging behind the leading internal combustion engine element qualified for upgrade opportunities. While Mercedes, Audi, Ferrari, and Honda gained allowances earlier in the year behind Red Bull's power unit, single-seater director Nikolas Tombazis confirmed the FIA is working with teams to refine the system for future seasons.
