The FIA has published the results of the first two assessments of Formula 1 power-unit performance under its ADUO framework, with Red Bull-Ford established as the benchmark and rival manufacturers receiving varying levels of technical concessions.The first assessment, completed after the Canadian Grand Prix, identified Mercedes as being approximately 2–4% behind the benchmark. As a result, Mercedes was granted one additional homologation for both the 2026 and 2027 seasons, alongside increased spending allowances and additional test-bench capacity.Ferrari, Audi and Honda were found to be more than 4% behind the benchmark. Each manufacturer was therefore awarded two additional homologations for both 2026 and 2027.The second assessment, which concluded following the Hungarian Grand Prix, resulted in no further homologation concessions. The FIA has not disclosed the precise performance figures, citing the confidentiality of the technical data submitted by the manufacturers.The third stage of the assessment will cover the races from the Dutch Grand Prix through to the Mexican Grand Prix.Nicolas Tombazis, the FIA’s Director of Single-Seater Racing, said the findings from the second assessment demonstrate that the federation’s methodology is accurately identifying differences in power-unit performance.
The FIA will continue to keep the underlying data confidential while engaging with the manufacturers on any potential changes to the ADUO framework.
