Image: XPB Images<\/p>\n<p>The governing body released the outcome of its second Additional Development and Upgrade Opportunities (ADUO) review, <a href=\"https:\/\/speedcafe.com\/f1-news-2026-engine-upgrades-ferrari-mercedes-red-bull-aduo-system-latest-reason-why-monaco-grand-prix\/\" rel=\"nofollow noopener\" target=\"_blank\">with the competitive order established earlier in the season remaining unchanged<\/a>.<\/p>\n<p>According to the results, Red Bull Ford continues to set the benchmark, while Mercedes sits between two and four percent behind and Ferrari, Audi and Honda remain more than four percent away.<\/p>\n<p>It means no new homologation opportunities have been awarded following the second assessment period, which incorporated data through to the Hungarian Grand Prix.<\/p>\n<p>Mercedes retains the additional upgrade it earned for both 2026 and 2027 following the opening assessment, while Ferrari, Audi and Honda each have two additional homologation opportunities available this year and another two next season.<\/p>\n<p>Those allowances are accompanied by additional spending and testing capacity designed to help manufacturers close performance deficits.<\/p>\n<p>Mercedes receives an extra US$3 million (A$4.18 million) under the cost cap and 70 additional hours of bench testing as a manufacturer between two and four percent behind.<\/p>\n<p>The available allowance increases depending on the size of the deficit, rising to US$4.65 million (A$6.48 million) and 100 hours for manufacturers between four and six percent behind.<\/p>\n<p>A deficit of six to eight percent brings US$6.35 million (A$8.85 million) and 150 hours, while manufacturers between eight and 10 percent behind can receive US$8 million (A$11.15 million) and 190 hours.<\/p>\n<p>The FIA has not disclosed where Ferrari, Audi and Honda sit within those bands.<\/p>\n<p>ADUO opportunities are not cumulative, meaning the second review has not added to the concessions already awarded earlier in the season.<\/p>\n<p>That leaves Red Bull unable to make use of the catch-up provisions despite its continued concerns over how the system measures performance.<\/p>\n<p>Its position as the benchmark is based specifically on the internal combustion engine rather than the performance of the complete hybrid power unit, with areas including battery performance and energy deployment not determining the ADUO ranking.<\/p>\n<p>That distinction has fuelled debate throughout the season, particularly with Mercedes widely regarded as possessing the strongest overall power unit package.<\/p>\n<p>Mercedes team principal Toto Wolff added to the controversy following the Belgian Grand Prix <a href=\"https:\/\/speedcafe.com\/f1-news-2026-toto-wolff-engine-mercedes-admission-aduo-update-latest-laurent-mekies-red-bull-reaction\/\" rel=\"nofollow noopener\" target=\"_blank\">when he declared Mercedes had the most powerful power unit<\/a>.<\/p>\n<p>\u201cWe are trying our best as a team. We have the most powerful power unit, a strong car that is capable of winning.<\/p>\n<p>\u201cEveryone is giving their maximum to minimise the mistakes, and still it happens because we are humans at work.\u201d<\/p>\n<p>Red Bull team principal Laurent Mekies subsequently backed Wolff\u2019s assessment despite the FIA\u2019s numbers placing Red Bull Ford at the top of the ICE rankings.<\/p>\n<p>\u201cToto is right. I also think that they have the most powerful power unit,\u201d Mekies said at the Belgian Grand Prix.<\/p>\n<p>Red Bull sought a review of the FIA\u2019s findings from the opening ADUO assessment after disputing the scale of the advantage attributed to its engine, but that process has not resulted in a change to the ranking.<\/p>\n<p>FIA single-seater director Nikolas Tombazis defended the methodology following confirmation of the latest results.<\/p>\n<p>\u201cThe FIA has undertaken thorough and exhaustive analysis as part of our ADUO review process,\u201d Tombazis said.<\/p>\n<p>\u201cWith the release of the findings of period two, we are confident that, based on the quality of the data, its analysis is incredibly robust, giving us a high level of confidence in our findings.\u201d<\/p>\n<p>The FIA did not publish the detailed performance data behind its calculations because of the commercially sensitive information involved.<\/p>\n<p>\u201cWe also have to respect the confidentiality and intellectual property of the teams and their power unit manufacturers in disseminating any details from the findings.\u201d<\/p>\n<p>Honda\u2019s updated power unit introduced at the Dutch Grand Prix was not part of the latest assessment, with the review period ending before the Zandvoort weekend.<\/p>\n<p>Red Bull\u2019s next opportunity to qualify for ADUO assistance will therefore depend on how the manufacturers compare during the final assessment period of the season.<\/p>\n<p>The FIA also acknowledged that the framework could be refined after its first season of operation.<\/p>\n<p>\u201cThis is the first year of ADUO so naturally there are areas which we may evolve over time, in discussion with all the PU manufacturers,\u201d Tombazis said.<\/p>\n","protected":false},"excerpt":{"rendered":"Red Bull has once again topped the ADUO rankings released by the FIA.
