The FIA has announced its final Additional Development and Upgrade Opportunities (ADUO) results for the 2026 Formula 1 season, with no changes granted for any power unit manufacturer. From this season, the FIA introduced a mechanism allowing power unit manufacturers to make updates via tokens under a performance scale if they fell behind the leading engine. After the first period in 2026, Red Bull Ford Powertrains emerged as the benchmark, while Mercedes’ internal combustion engine trails by between 2-4%, giving Mercedes one additional upgrade this year and one more next season.
Ferrari, Audi and Honda fell into the category of being more than 4% behind on ICE power, granting them two upgrades during the current campaign and two more in 2027. Red Bull Ford Powertrains requested a review of the ADUO analysis, which delayed the official publication of the first results, as it disputed being considered the manufacturer with the strongest engine. The third and final FIA analysis of ADUO, covering Dutch GP up to and including US GP, also resulted in no changes.
There was also no change in the second ADUO period over the summer. The next ADUO period will start in 2027, covering the opening six races from the Bahrain GP to the Miami GP.
