pole

Hamilton also faces an investigation for failing to slow sufficiently for the yellow flags waved when Leclerc lost control.

Norris topped all three sessions in sprint qualifying and had a comfortable advantage over Piastri throughout.

He said: “It was a little bit tougher than I would have liked. But we did the job we needed to do, which was to be fastest today.

“Qualifying is always one of the best things here. It’s difficulty, it’s bumpy, it’s tricky, always a joy, always puts a smile on your face.

“But a long weekend, another qualifying and another couple of races to go but a good start.”

Rain is forecast for Saturday morning in Sao Paulo, when the sprint race is due to start at 14:00 GMT. Qualifying for the grand prix is at 18:00.

Norris’ result is the best possible start to the weekend and gives him the opportunity to build his championship lead – eight points are awarded to the winner of the sprint, seven for second and so on down to eighth place.

Antonelli impressed in second, his best time set on his first lap, while the surprise package of qualifying was Alonso, who set the fastest time in the second session and was just 0.253secs off pole in his midfield car in the final shootout.

His team-mate Lance Stroll was seventh fastest, ahead of Leclerc, Racing Bulls’ Iscak Hadjar and Sauber’s Nico Hulkenberg.

Piastri, meanwhile, cut a somewhat forlorn figure. He had a difficult weekend in the US a week ago and thought he had found the answers. But as he put it: “What’s been a bit surprising here has just been that the gap has been the same pretty much every session.

“I feel like I’ve done some decent laps through the weekend, but everything seems to be about 0.4-0.5secs off.”

Team principal Andrea Stella said Piastri was losing a little bit everywhere, and Piastri said: “I feel like I did a reasonable job and the car felt reasonable as well. So, yeah, the lack of lap time is a bit of a mystery.”

Piastri has been off Norris’ pace whether on short runs or long, low fuel or high, so it is more in hope that he said of the race: “If I can unlock the pace in the car, we can have some fun. We’ve just got to try to unlock it.”

This is now Piastri’s fifth difficult weekend in a row, his form mysteriously evaporating since he won in the Netherlands at the end of August.

He did not talk directly about what this means for the championship, but there was no hiding the meaning behind one of his comments: “There’s a lot of things I could worry about, but ultimately being that far off when you feel like you’ve done a reasonable job is a difficult place to be. And so that’s my biggest concern at the moment.”

Stella said that the conditions in Mexico, like those in Austin, are ones in which Norris thrives and Piastri is less comfortable – low grip, hot tyres.

And he said that “every evidence, every piece of data, every indirect measurement of information we have, tells us that there is no problem with the car”.

He added that it was “good” for McLaren to be able “to confirm that we can have the fastest car”, adding that their “focus is to stop the momentum of Verstappen”.

Red Bull’s Max Verstappen beat McLaren’s Lando Norris to pole position at the United States Grand Prix with championship leader Oscar Piastri down in sixth.

After the McLaren drivers crashed out of the sprint earlier on Saturday, neither was able to challenge Verstappen even though the world champion failed to complete a final run in qualifying.

Verstappen was sent out too late to get around in time to start a last lap before the chequered flag but still beat Norris by 0.291 seconds.

It was an imperious performance that underlined why McLaren are concerned about his threat in the drivers’ championship.

Norris saved his best for last in a difficult session to pip Ferrari’s Charles Leclerc to second on the grid by just 0.006secs.

But Piastri, who has looked out of sorts all weekend, was not quick and he ended up 0.574secs off the pace, and behind Mercedes’ George Russell and the second Ferrari of Lewis Hamilton.

Piastri had looked to be struggling compared with Norris since the start of practice and was a good chunk off the Briton in all three qualifying sessions.

Norris said: “Disappointed not to be on pole but not a surprise for us to be just a bit slower than the Red Bull lately.

“A little couple of bits here and there I could have improved on and caught a few bumps a little bit wrong, that’s the difficulty of this track. Otherwise, all happy.”

Piastri said: “A pretty scruffy lap. Just didn’t really get it together. In some ways, I feel a bit fortunate to be third. The pace in the car is good. It’s nothing major, just been a bit of a messy lap and hopefully I can tidy it up tomorrow.”

The sprint offers eight points for the winner down to one for eighth place.

The stand-out performance in qualifying came from Hulkenberg, the first time he has qualified in the top 10 all year, and the best Sauber performance of the season.

Their previous top grid position was seventh for team-mate Gabriel Bortoleto in Hungary at the start of August.

“Satisfied, happy, as you might imagine,” the German said. “P1 looked too good to be true. We weren’t sure if it was the real deal but we were able to continue that trend. Hopefully we can hang on to it this weekend.

“The pace was just there. The car seemed to be fast and in a good window, hit the sweet spot, I think that’s all.”
