Lewis Hamilton, Charles Leclerc discuss reasons why Ferrari went from US GP pole favourites to behind Kimi Antonelli, Red Bulls on grid

For the first time this season, Ferrari went into qualifying having topped all three practice sessions in Austin, on a weekend their car features the team's final significant upgrade of the season.

Leclerc finished second fastest to McLaren's Lando Norris in Q1, but only after the McLaren driver completed a second run to do so, and then was then back at the head of the field in Q2.

But the Scuderia found themselves on the back foot immediately from the start of Q3 with Leclerc holding a provisional fourth and Hamilton sixth after the first runs of the decisive final phase.

Hamilton improved one place to fifth on his final run, but Leclerc stayed where he was, to leave the Ferraris behind the two Red Bull drivers and Mercedes polesitter Kimi Antonelli for the start of Sunday's 56-lap race.

Yet had Leclerc matched his benchmark time from the theoretically-slower Q2 session he would have qualified second.

Team principal Frederic Vasseur told Sky Sports F1 : "Bit of mixed feelings for sure. The potential was there over the weekend. We had good pace in free practice.

"Until the last corner we are fighting for pole but it is like it is."

On team radio after ending up fifth, 0.276s away from pole, a bemused Hamilton said: "These guys must be turning up [their engines] for that last Q3 because where did that time go?"

Speaking to Sky Sports F1 afterwards, Hamilton said that his car's handling had felt consistent through all three sessions, suspecting that the team's straight-line speed deficit had again played a central role in them being usurped.

"We did a really good job overnight. The car felt really good in FP3 - competitive," said Hamilton, who had topped that final practice session.

"Q1 and Q2 both felt pretty strong. It felt like we were right there in the fight and the car was just as good as.. we didn't make any changes, the car didn't flip upside down in Q3. It was a really good lap.

"Those guys just somehow took another step. I don't know what it is. Ultimately we do lose, I think we are a few tenths off on the straight as we usually are, but a great lap by Kimi and the power deficit to the Red Bull and Mercedes is still significant.

"Our car is clearly as good as theirs through the corners but we lose that down the straights."

Leclerc, though, offered an alternative suggestion, believing that a decrease in track temperature for the start of Q3 had made a pivotal difference to their competitiveness, causing tyre warm-up issues.

Asked if it was again a case of rivals finding something extra to them at the end of qualifying, Leclerc replied: "This time I think it's slightly different in that I don't think the others have changed anything from Q2 to Q3. Where we have lost is on ourselves and that is mostly the tyres.

"The out lap was extremely difficult. There was a bit more cloud in Q3. We lost one or two degrees of track temp and, for us, it was night and day different and already from the out lap I felt I was having lots of difficulties.

"It's a shame that it happened in Q3 because I strongly believe that we had the pace to be fighting in front but unfortunately not today again."

Ferrari last started a Grand Prix from pole position in 2025 in Hungary.

Why Ferrari are not out of victory hunt yet

All is not yet lost, however, for Ferrari in terms of fighting at the front in Sunday's race on a track where overtaking is possible and tyre degradation is predicted to be high.

Leclerc felt they could even still repeat his Austin victory from the same starting berth two years ago.

"Yeah [Ferrari can still win the race]. The last time I think I started from fourth here I won so I hope we can do the same," he said.

"Just a good start and then where you position your car and trying to anticipate what is going to happen [is key] because there are many different scenarios that can happen in such a turn one with very wide entry.

"Then if you are doing the right choices you can get a lot more than any other track, so I'm looking forward to that."

Hamilton was staying cautious given the pace of the cars ahead, but expressed hope that Ferrari could still be a threat over the full race distance.

"Starting position isn't everything. You have to have really good pace to overtake," he added.

"It's a long race. There was more degradation than anticipated on Friday on the long runs. Our car will hopefully be decent and we will do the best job we can to apply pressure.

"To beat the Red Bulls and Mercedes will be challenging, for sure, but we will give it absolutely everything."
