The Red Bull-Ford power unit has been officially classified as the benchmark manufacturer under the FIA’s Additional Development and Upgrade Opportunities (ADUO) system. Because the FIA’s assessment identifies Red Bull as having the strongest Internal Combustion Engine (ICE), the team is currently prohibited from implementing any power unit upgrades. In contrast, trailing manufacturers are granted extra development allowances: Mercedes is permitted one extra upgrade, while Ferrari, Honda, and Audi are allowed two each. This ruling has drawn criticism regarding a potential flaw in the ADUO framework. Critics argue the system measures performance based solely on the ICE via the FIA’s ICE Performance Index, ignoring the Energy Recovery System (ERS). While Red Bull is locked out of ICE upgrades, competitors can still modify their ERS packages, turbochargers, and cooling systems. Max Verstappen has publicly questioned ~~the implications of~~ these measurements. He noted that the data, which suggests Mercedes trails Red Bull by 2% to 4% in ICE performance, fails to account for the battery or total power delivery. Verstappen emphasized that the ICE and battery are distinct components, suggesting measurements, noting that a strength in combustion could be offset by a weakness in electric deployment. ~~He maintained that continuous~~ In response to these controversies and unintended consequences, the FIA is now evaluating potential reforms to the ADUO system.
