Red Bull’s Engine Future Teeters on Crucial Decision
Highlights
- FIA to announce Red Bull’s engine upgrade eligibility before Italian GP.
- Second ADUO evaluation covers Monaco to Hungarian Grand Prix performance.
- Red Bull barred from upgrades if engine is within 2% of rivals.
- Third ADUO period offers final upgrade chance before 2027 reset.
- FIA admits ADUO system is accurate but may need refinement.
- Red Bull awaits decision impacting 2023 season engine development plans.
Red Bull expects a ruling before the Italian Grand Prix on whether its power unit qualifies for in‑season upgrades under FIA ADUO rules. The verdict will shape development plans.
The second ADUO evaluation covers Monaco to Hungary. If Red Bull is over 2% behind any rival, it unlocks extra dyno hours, permitted spend, and a new homologated specification.
FIA’s second ADUO verdict arrives before Monza and will decide Red Bull’s in-season engine development rights.
The first ADUO audit, from Australia to Canada, labelled Red Bull the benchmark. The FIA judged its engine over 2% clear, barring extra development. A subsequent challenge reportedly changed nothing.
Under the process, the FIA must notify manufacturers within a fixed window, enabling homologated upgrades if eligibility is granted. This announcement lands just before Monza.
This call is strategically pivotal for Red Bull’s programme. A deficit exceeding 2% across Monaco to Hungary would unlock development rights for the remainder of the year.
Red Bull is barred from ADUO upgrades if its engine sits within 2% of the class leader.
If the engine sits within 2% of the nearest competitor, likely Mercedes, or ahead, Red Bull will again be denied further development this season.
One final window remains. The third ADUO period runs from Dutch to United States Grands Prix, the last chance before the 2027 reset, as noted in recent Dutch GP coverage.
The system’s focus is narrow. ADUO measures only internal combustion performance, helping explain why Red Bull can lead the ICE table while many regard Mercedes as owning the strongest package.
Tombazis says the methodology is accurate but should be streamlined to reduce complexity and contention.
FIA single‑seater director Nikolas Tombazis maintains the measurement approach is sound, but accepts refinements could streamline the process and reduce controversy.
He also rejects suggestions of sandbagging. With opportunities granted only once per season, manufacturers gain nothing by deliberately lagging rivals.
Approaching Monza, Red Bull awaits confirmation that will define its remaining programme and resource deployment. The verdict follows a recent Red Bull F1 warning that underlined mounting competitive pressure.
