Overview
- The FIA's first ADUO assessment, issued after the Canadian Grand Prix and circulated during the Monaco weekend, marked Red Bull Powertrains as the internal combustion engine benchmark and qualified Ferrari for two 2026 upgrade opportunities.
- Audi quietly fitted revised internal combustion engines and turbochargers to both cars in Barcelona as the first manufacturer to deploy an ADUO‑driven change, with the work focused on drivability and throttle response rather than large outright power gains.
- Ferrari confirmed a modest first ADUO ICE update at the Austrian Grand Prix and has a larger turbocharger package planned after the summer break, while the team says the Austria step alone will not reorder the front of the grid.
- Red Bull formally challenged the FIA ranking and the governing body is rechecking torque‑sensor data; sources now say the original ADUO verdict is unlikely to be overturned, so provisional upgrade entitlements remain in place.
- ADUO measures only ICE output via standardized in‑car torque sensors and grants extra homologation slots, dyno hours and scaled cost‑cap leeway, but teams warn the metric omits hybrid/ERS contribution and that dyno gains take months to convert into race‑ready performance.
