Threat of heavy rainstorm in Miami causes organisers to move up race start time to 17:00 GMT on Sunday.

Championship-leading teenager Kimi Antonelli has claimed pole position for the Miami Grand Prix as the race’s start time was brought forward by three hours due to an expected heavy rainstorm.

The 19-year-old Italian, the youngest title race leader in Formula One history, resisted a late charge by four-time champion Max Verstappen in a tense qualifying session on Saturday.

The Mercedes driver produced a fastest lap of one minute 27.798 seconds to top the times ahead of Red Bull’s Verstappen with Charles Leclerc third quickest in his Ferrari.

World champion Lando Norris, who won the sprint race earlier in the day, will start his McLaren from fourth in Sunday’s grid.

It was Antonelli’s third pole and his third in consecutive races, a feat that draws him alongside great former champions Ayrton Senna and Michael Schumacher in the record books.

His Mercedes teammate George Russell was fifth ahead of seven-time champion Lewis Hamilton in the second Ferrari and Oscar Piastri, who was seventh in the second McLaren.

Alpine’s Franco Colapinto was eighth ahead of Isack Hadjar in the second Red Bull and the second Alpine of Pierre Gasly.

“It has been an amazing day for me to be on pole again,” Antonelli said.

“It was obviously a difficult sprint for me earlier, but I am super happy with this recovery. I got a little too excited in that last lap in Q3, but my first lap was good enough.

“I was so stressed because I was waiting for everyone to finish their laps, but it was good enough, and now, hopefully, I will have a magic start tomorrow.”

‘Heavier rainstorms’

The Miami Grand Prix will start at 1pm (17:00 GMT) rather than the previously scheduled 4pm (20:00 GMT) due to a forecast of extreme weather, including potential thunderstorms, officials announced on the eve of the race.

The sport’s governing body, FIA, along with commercial rights holders and local promoters acted “due to the weather forecast that is expected to bring heavier rainstorms later in the afternoon close to the original planned race start time”, they said in a statement.

“This decision has been taken to ensure the least amount of disruption to the race, and to ensure the maximum possible window to complete the Grand Prix in the best conditions and to prioritize the safety of drivers, fans, teams and staff.”

The change was made as F1 returns from a five-week hiatus due to the United States-Israel war on Iran, which several teams exploited with upgrade packages on their cars.

“For me to be on the front row is way better than I expected,” said Verstappen, who was close to his best in his heavily revised Red Bull.

“Let’s hope for a good start. I’ve not had many of them this year.

“The team has worked flat out for the past few weeks to make me more comfortable in this car.”

‘No grip’

The qualifying session began in sweltering heat and a swirling wind as Valtteri Bottas led out in his Cadillac before teammate Sergio Perez.

It took time for the lap times to tumble before the leading contenders clocked fast laps with Norris and Verstappen setting the pace with Antonelli and the two Ferraris.

Verstappen grumbled his tyres “have no grip” as he was outpaced by both Ferraris with Hamilton top in 1:28.477 until Antonelli took over in 1:28.352 with Russell slotting in third with an identical time to Hamilton.

Ferrari have clearly improved their set-up after the earlier sprint race won convincingly by Norris in a McLaren one-two ahead of Piastri.

Like the Italian team, Mercedes also seemed to be quicker, and Antonelli improved to 1:28.289 before, in a final flurry, Verstappen took command in 1:28.116 to finish Q2 ahead of Antonelli, Leclerc, Piastri and Hamilton. Norris improved to seventh.

Piastri and Norris set the pace in Q3 before Verstappen and Leclerc outdid them and Antonelli, with a sizzling lap in 1:27.798, securing provisional pole after the first runs, three-tenths clear of Leclerc’s Ferrari.

The top five were separated by just hundredths of a second with Hamilton sixth, 0.578 off the Italian’s pace as they paused before the drama of the late final runs.
