Formula One leader Mercedes granted engine upgrade under ADUO system
The sport has entered a new engine era this season, and ADUO is designed to prevent one manufacturer from establishing a significant advantage without rivals being able to respond.
The FIA has once again determined that Red Bull holds the most powerful internal combustion engine in Formula 1, according to the latest rankings. This finding echoes the initial results from three months ago, leaving the team disappointed as they had hoped for the possibility of upgrading their engine. The FIA's Additional Development and Upgrade Opportunities (Aduo) programme, introduced this year, is designed to allow manufacturers with a deficit to catch up.
However, the programme only measures the power of the internal combustion engine, excluding its electrical components, which make up nearly 50% of the total performance. Mercedes and Ferrari have been classified as having engines that are 2-4% and above 4% behind the best internal combustion engine, respectively. As a result, Mercedes are permitted one additional upgrade in 2026 and 2027, while Red Bull and the other manufacturers, except Red Bull, are allowed two upgrades each.
The FIA's findings are based on a thorough and exhaustive analysis, according to Nikolas Tombazis, FIA director of single-seaters. However, the FIA must respect the confidentiality and intellectual property of the teams and their power-unit manufacturers when sharing the findings.
