The FIA has officially closed the book on the 2026 Formula 1 season’s first Additional Development and Upgrade Opportunities (ADUO) cycle, confirming that no changes will be granted to any power unit manufacturers. This final decision resolves a contentious dispute initiated by Red Bull Ford Powertrains, which challenged the initial assessment that placed them at the top of the performance hierarchy. By upholding the original findings, the governing body has locked in the development trajectories for all engine suppliers heading into the latter half of the season.
Red Bull Ford retains benchmark status after successful challenge to initial performance data
Under the new regulatory framework, teams receive development tokens based on their Internal Combustion Engine (ICE) performance relative to the benchmark. The data from the Australian to Canadian Grand Prix period confirmed Red Bull Ford as the leader, while Mercedes trails by 2-4%, securing one additional upgrade for 2026 and one for 2027. Ferrari, Audi, and Honda, identified as more than 4% behind on ICE power, have been allocated two upgrades for the current campaign and two more for the 2027 season, providing them with a significant catch-up window.
This finalization removes uncertainty from the competitive landscape, allowing manufacturers to execute their pre-planned development schedules without further regulatory delays. The ADUO mechanism aims to level the playing field by rewarding lagging teams with extra development opportunities, but the FIA’s refusal to alter the benchmark status underscores the strict adherence to the agreed-upon performance metrics. As the season progresses, the focus will shift to how these allocated upgrades translate into on-track performance, particularly for the manufacturers granted the highest number of development slots.
