The FIA has revealed the ADUO results following the third analysis period of the season.
"For the third period, the relative performance gaps to the leading ICE evolved, but these changes did not result in any additional homologations being granted to the Power Unit Manufacturers," the motorsport federation has declared in today's announcement.
Nikolas Tombazis, the federation's single-seater director said: "The FIA has undertaken extensive analysis as part of the review of ADUO this year. Based on the quality of the data and the robustness of the assessment process, we are confident in our findings and the conclusions reached.
"The first year of implementation has also reinforced our belief that the ADUO concept is the right one for Formula 1. However, it is important that the system continues to evolve to ensure it remains efficient, relevant and fit for purpose. To that end, we have been working closely with the Power Unit Manufacturers and teams to explore refinements to the methodology that will support the continued effectiveness of ADUO in future seasons."
