Hamilton also pointed to an insufficient power deficit on the straights and poor tyre performance as the twin causes . The three-stop strategy was forced by the heat and degradation, but he admitted it "never really worked"
.
Charles Leclerc was even more blunt:
Fred Vasseur — speaking after qualifying — was cautiously optimistic, saying Ferrari would "take the positives" from Leclerc P2 and Hamilton P3 despite Russell pipping them to pole . After the race, Vasseur defended the strategy choices, acknowledging the pace deficit: "The pace of Mercedes was better than us"
. He pointed to the extreme degradation forcing Ferrari's hand on a three-stop when rivals managed two stops comfortably
. Vasseur said there were "no regrets" on strategy given the car's underlying issues
.
Ferrari introduced its first ADUO (Additional Development and Upgrade Opportunities) engine upgrade at Austria, using FIA data showing its power unit was more than 2% behind the benchmark . Ferrari committed to a "hotter engine concept" — running higher intercooler intake temperatures (estimated 110–115°C) to improve combustion efficiency, reportedly worth around 7 extra horsepower
.
But the upgrade backfired in the heat:
The net result: Ferrari went from a front-row lockout in qualifying to being the slowest of the top four teams in race trim, dropping Hamilton from 2nd in the championship to 3rd and leaving both drivers searching for answers a week before the British Grand Prix.
