Overview
- Ferrari used both ADUO‑authorised engine steps, bringing ADUO 2 to Monza, but team principal Fred Vasseur said the changes delivered only incremental gains and the team is still “missing pure power.”
- Monza lap and telemetry data showed a measurable straight‑line shortfall for Ferrari — about 5.6 km/h in the cited qualifying sample — and the Italian Grand Prix result widened Ferrari’s constructors’ gap to Mercedes.
- The FIA’s ADUO system assesses only internal combustion engine output, not hybrid battery capacity or deployment, which teams say can misrepresent overall power‑unit performance on track.
- Mercedes has not yet fitted its one permitted ADUO hardware step but is reported to be preparing an upgrade for the late‑season triple‑header that would also be supplied to its customer teams under the rules.
- Red Bull Powertrains remains the ICE benchmark and cannot upgrade while the ADUO ranking stands, a finding the team has publicly mocked, and the next ADUO monitoring window will review Dutch‑to‑Mexican Grand Prix data.
