Kimi Antonelli became Formula 1's youngest ever pole-sitter as he edged out his Mercedes team-mate George Russell in qualifying for the Chinese Grand Prix.
Russell, who won the Sprint earlier on Saturday, appeared to have the edge over Antonelli but suffered a technical issue in the final part of qualifying that limited him to one rushed lap at the end of the session.
Antonelli took full advantage of getting two clean runs in, setting a time of 1:32.064 on his second effort to beat Russell by 0.222s as Mercedes locked out the front row for the third time in as many qualifying sessions this season.
The 19-year-old breaks a record set by four-time world champion Sebastian Vettel, who claimed his first F1 pole at the age of 21 at the 2008 Italian Grand Prix when he was driving for Toro Rosso.
"It was a pretty clean session, so (I'm) really happy," said Antonelli, who had previously claimed a Sprint pole at last year's Miami Grand Prix during his rookie campaign.
"George had an issue in Q3 and it would have been cool to see him with two sets (of tyres). I saw he had the issue and tried to keep my focus to stay calm and deliver a good lap."
Lewis Hamilton produced another encouraging display as he edged out his Ferrari team-mate Charles Leclerc for third, with little more than a hundredth of a second separating the pair as they finished three tenths back from Antonelli.
Oscar Piastri beat his McLaren team-mate Lando Norris to fifth as the reigning constructors' champions showed some improvement but still lacked the pace to challenge for pole.
Max Verstappen's tough start to the season with Red Bull continued as he could only qualify eighth, finishing behind Alpine's Pierre Gasly.
Verstappen's team-mate Isack Hadjar was ninth ahead of Haas' Oliver Bearman, but the French driver was fortunate to make it through Q2 after Gabriel Bortoleto spinning off triggered yellow flags that prevented several others from having the chance to knock the Red Bull out.
The six drivers knocked out in Q1 were the same as in Sprint Qualifying a day earlier, with Williams' hugely disappointing start to the season continuing as Carlos Sainz edged out team-mate Alex Albon for 17th.
Aston Martin suffered another blow amid their engine struggles as Lance Stroll was beaten to 20th by Valtteri Bottas for F1 newcomers Cadillac.
Since Mercedes unleashed their pace at last weekend's season-opening Australian Grand Prix, Russell has appeared to have a significant edge over his young team-mate.
The Brit had quite comfortably outqualified Antonelli in Australia and in Friday's China Sprint Qualifying and also went on to win both races.
The pattern looked set to continue on Saturday in Shanghai until Russell was beset by a series of issues in the business end of the session.
Having already done a lap comfortably fast enough to get him through Q2, Russell reported an issue with his front wing and demanded it be changed, while also requesting checks to the floor of his car.
When he emerged for his first run in Q3, he suddenly stopped on track, and after an agonising period stationary, was able to coax his W17 back to the garage.
The mechanics worked swiftly to get the car ready to go back out on track, but it was only cleared in time to leave Russell with one flying lap, with drama added by the fact he would be the last of all the drivers in Q3 to set a time.
Russell was ultimately unable to get within two tenths of Antonelli's best time, but the second place he salvaged was a far better outcome than the 10th place that was looming had he failed to set a time.
"Definitely damage limitation," Russell said. "Q2, the front wing broke, we were wrapping our heads around that. Then obviously went out in Q3, car stopped on track, car wasn't restarting, couldn't change gear.
"Happy standing here because starting the last lap I had no battery, no tyre temp, no nothing. But the team have done a really great job to get us into this position, it could have been much worse."
