TL;DR
The FIA is reviewing its engine performance results following Red Bull’s ranking as the top power unit, despite internal disagreements. The outcome could influence future upgrades and regulations.
The FIA is reviewing its recent engine performance assessment after ranking Red Bull’s power unit as the best in Formula 1, despite internal disagreements and surprise from teams like Mercedes and Red Bull itself.
The FIA released a document earlier this month ranking the performance of the 2026 power units, with Red Bull identified as the leading manufacturer based on internal combustion engine (ICE) performance. This ranking influences engine upgrade opportunities for the current season, where Red Bull will not receive an upgrade, while Mercedes, Ferrari, Audi, and Honda are eligible for varying numbers of upgrades.
Red Bull, which has developed its own engine for the first time in F1, expressed surprise at the results. Team principal Laurent Mekies stated that they do not see evidence indicating an advantage over Mercedes and have opened a dialogue with the FIA to clarify the assessment. The FIA is still evaluating the findings and has not officially confirmed the results, which are under review ahead of next week’s Austrian Grand Prix.
Meanwhile, Mercedes team principal Toto Wolff welcomed the opportunity for engine upgrades, emphasizing that the FIA’s measurements are straightforward and data-driven. The review process includes additional assessments scheduled for later this year, which will also impact the 2027 season.
Implications of the FIA’s Engine Performance Review
This review could significantly impact the balance of power in Formula 1, influencing engine upgrade opportunities and potentially altering competitive dynamics. If the FIA’s findings are upheld, Red Bull’s engine advantage might be confirmed, affecting how teams approach development and regulation compliance.
The controversy highlights ongoing tensions over engine performance assessments and the transparency of the FIA’s measurement methods. For fans and teams, the outcome could redefine expectations for the remainder of the season and future seasons.

Background on the ADUO Engine Performance Assessment
The FIA introduced the Additional Development and Upgrade Opportunities (ADUO) system to regulate engine development and ensure fair competition among power unit manufacturers. The system assesses internal combustion engine performance separately from electrical components, which account for nearly half of the power output.
Earlier this month, the FIA released a ranking based on internal data, placing Red Bull at the top, with Mercedes, Ferrari, Audi, and Honda positioned behind, each with specified upgrade allowances. Red Bull’s ranking is notable because they built their own engine for the first time, and their surprise at the results has sparked internal discussions and calls for clarification.
Red Bull team officials have questioned the measurement process, citing limitations in sensor data and the complexity of accurately assessing engine power solely through the FIA’s methods. The review process is ongoing, with further evaluations scheduled later this year.
“We do not see one single data sample that indicates we have an advantage over Mercedes. We are open to a deeper conversation with the FIA to get the right picture.”
