Overview
- Audi quietly fitted revised internal combustion engines and turbochargers to both cars in Barcelona late June, with the changes focused on drivability and not large outright power gains.
- Ferrari confirmed it will run its first ADUO‑enabled engine update at the Austrian Grand Prix, a small ICE change paired with new Shell fuel that media dyno estimates put at roughly 4–5hp plus 2–3hp from fuel, worth about one‑tenth of a second per lap at the Red Bull Ring.
- The ADUO system measures only internal combustion engines using in‑car torque sensors and grants extra development tokens, dyno hours and scaled cost‑cap allowances to manufacturers judged behind the benchmark (one upgrade for ~2% deficit, two for >4%).
- The FIA is conducting a review after Red Bull challenged the initial ranking that named Red Bull Powertrains the ICE benchmark, but multiple sources say the original provisional allocations are expected to stand while the recheck concludes.
- Teams stress that dyno or bench gains usually take months of engineering and integration to convert into meaningful race pace, and manufacturers have multi‑step roadmaps — Ferrari plans a larger turbo upgrade after the summer break — that could reshape the pecking order over the second half of the season.
