Why the FIA still hasn’t released ADUO results

The FIA was expected to publish the first ADUO classifications shortly after the Canadian Grand Prix on May 24, marking the end of the initial evaluation window defined in the updated May 8 technical directive. Under the new system, engine manufacturers are placed into performance tiers after the sixth, twelfth and eighteenth races, with those lagging behind granted additional development opportunities. Yet thirteen days have passed without any communication, and the topic was notably absent from discussions in Monaco. According to paddock reports, the delay is tied to ongoing negotiations over the 2027 power‑unit regulations.

Ferrari are reportedly unhappy that a potential redesign aimed at increasing fuel flow could allow already competitive manufacturers to make substantial improvements, undermining the intended ADUO freeze. Journalists Thomas Maher and Julianne Cerasoli both indicated that the FIA may wait until meetings with engine suppliers conclude this weekend in Monte Carlo before releasing the long‑anticipated results.
