2026 F1 ADUO review: no extra upgrades reported

Autosport, Motorsport.com and RaceFans reported the FIA’s final 2026 ADUO review granted no extra development scope to any power unit manufacturer.

Autosport and Motorsport.com reported that the FIA’s final 2026 Additional Development and Upgrade Opportunities review brought no extra development scope for any power unit manufacturer. No primary FIA document was supplied in the source set, so that outcome remains reported rather than independently confirmed here.

Both outlets said the ADUO mechanism was added to the 2026 Formula 1 regulations as a way for manufacturers to gain extra development opportunities if set conditions were met. With no changes granted in the final review, the reported position stayed unchanged through the last assessment of the season.

RaceFans also reported that FIA single-seater director Nikolas Tombazis defended the ADUO system while indicating the rules could be revised in future seasons. Without a primary publication from the FIA in the supplied material, any broader regulatory impact remains provisional.
