TL;DR
The FIA is reviewing its engine performance results after ranking Red Bull as the top power unit manufacturer, despite rival teams’ skepticism. Discussions with teams are ongoing.
The FIA is reviewing its recent assessment that ranked Red Bull as having the best Formula 1 engine, amid surprise and skepticism from rival teams. The governing body is currently evaluating its findings and holding discussions with teams, including Red Bull, ahead of the Austrian Grand Prix.
The FIA released a document earlier this month ranking the performance of the 2026 power units based solely on internal combustion engine (ICE) metrics, excluding electrical components. Red Bull was identified as the top-performing manufacturer, with other teams such as Mercedes, Ferrari, Audi, and Honda receiving engine upgrade allowances based on their relative performance deficits.
Red Bull, which has developed its own power unit for the first time, expressed surprise at the results. Max Verstappen questioned the ranking during the Barcelona-Catalunya Grand Prix, noting that Mercedes has won six of seven races this season despite Red Bull’s top engine status. Red Bull team principal Laurent Mekies confirmed ongoing dialogue with the FIA to clarify the assessment, emphasizing that they do not see a clear data sample supporting their engine advantage.
The FIA has not yet officially confirmed the ranking, and sources indicate that the governing body is reviewing its findings and consulting with all teams involved. Two additional ADUO reviews are scheduled later this year, which could influence engine upgrades for the 2027 season.
Implications of FIA’s Engine Performance Review
This review could impact the development strategies of F1 teams and influence the competitive balance for upcoming races and seasons. The ranking affects which teams can upgrade their engines and could lead to disputes over the measurement methods used. The process also raises questions about transparency and accuracy in performance assessments, which are critical for maintaining fairness in F1.

Background of Engine Performance Assessments in F1
FIA introduced the ADUO system to evaluate engine performance and allocate upgrade opportunities based on measured data. The system aims to prevent dominance by a single manufacturer and ensure fair competition. Red Bull’s rise as a constructor with a self-developed power unit marks a significant shift, and the recent ranking has sparked debate over measurement accuracy and the influence of internal combustion engine metrics in overall power unit performance.
Previously, the FIA’s assessments and upgrade allocations have been scrutinized, but this marks the first time Red Bull has been identified as having the leading ICE performance, despite their relatively recent entry into engine manufacturing.
“We are surprised to see Red Bull ranked as having the best engine, especially considering Mercedes’ race wins this season.”
— Max Verstappen

Unconfirmed Aspects of the FIA’s Engine Ranking Method
It remains unclear how the FIA precisely measured engine performance, especially given that the assessment considers only the internal combustion component and not electrical elements, which contribute significantly to overall power. The specific data samples and measurement techniques are not publicly disclosed, leading to questions about accuracy and potential biases.
Additionally, the official confirmation of the ranking results has not yet been issued, and the outcome of the ongoing discussions could alter the current standings or the interpretation of the data.

Upcoming Review Sessions and Potential Outcomes
The FIA plans two more ADUO reviews later this year, after the Hungarian and Mexican Grands Prix, which will further influence engine upgrade allocations for 2027. The governing body is expected to clarify its methodology and possibly revise the current rankings based on these upcoming assessments.
Teams are awaiting official confirmation of the current results, and Red Bull continues to engage with the FIA to ensure their engine performance is accurately represented. The results of these reviews could impact the competitive landscape in the 2026 and 2027 seasons.

Key Questions
Why is the FIA reviewing the engine performance rankings?
The FIA is reviewing its recent assessment to verify the accuracy of the engine performance rankings, which influence upgrade opportunities and competitive balance among teams.
What does Red Bull’s surprise mean for the sport?
Red Bull’s reaction suggests skepticism about the measurement process, and their engagement with the FIA indicates ongoing discussions that could impact future assessments and development strategies.
How might this review affect upcoming races?
If the rankings are revised, it could alter which teams are eligible for engine upgrades, potentially changing performance dynamics in future races.
Are electrical components of the power unit considered in this assessment?
No, the ADUO system currently only evaluates the internal combustion engine, not the electrical elements, which makes the overall power unit performance more complex to assess.
When will the final decision on the rankings be made?
The FIA is expected to finalize its review after the upcoming ADUO assessments later this year, with results likely announced before the start of the 2027 season.
