Overview
- Ferrari confirmed on Friday that it will fit its ADUO‑authorised 067/7 internal‑combustion unit at the Italian Grand Prix after repeated bench tests reached the FIA reliability threshold.
- The 067/7 package changes the combustion chamber and fits a larger turbocharger, and Ferrari forecasts about a 15 horsepower gain that engineers say should roughly halve the measured deficit to the leading Mercedes unit.
- The power upgrade will be used together with a new Shell fuel formulation and a lower‑drag version of the 'Macarena' rear wing plus blown‑exhaust tweaks to optimise top speed at Monza.
- Mercedes has confirmed Andrea Kimi Antonelli will take a back‑of‑the‑grid penalty for a full power‑unit change at Monza, which alters the immediate competitive picture for Ferrari’s home race.
- The move follows the FIA’s ADUO ranking that awarded Ferrari two upgrade opportunities after finding it more than 4% behind the benchmark; the ADUO process grants limited extra development but does not change hybrid deployment rules, so Ferrari focused the upgrade on combustion, turbo and fuel to gain straight‑line performance.
