Charles Leclerc recovered from a Q3 spin to take pole as Max Verstappen was left to rue a DRS failure in qualifying for the Spanish Grand Prix.
Ferrari driver Leclerc span out at turn 14 on his first flying lap but produced an immense time with his next and only completed attempt, to ensure he will start from the front of the grid.
All four of the Monegasque driver's Formula One victories have come after starting on pole. Some 28 of the past 31 winners at the Circuit de Barcelona-Catalunya qualified on the front row.
Verstappen aborted his final lap after reporting a loss of power, with Red Bull team principal Christian Horner confirming to Sky Sports that was due to a DRS issue.
The Dutchman will consequently start from second, with Ferrari's Carlos Sainz in third.
"I feel good. It was a difficult session, especially in Q3 because I made a mistake in the first run and then only had one lap," said Leclerc.
"But it went extremely well, I had a few moments but made it stick and very happy with pole position. It was a very good lap and the car was amazing too, so very happy.
"We've been struggling with tyres in the last few races compared to Red Bull, so Max is just behind. If we don't manage those tyres we will lose that advantage, so we need to get on top of it.
"I hope we can do a one-two. It will be great for the team and we will give it our all."
Verstappen acknowledged he may not have been able to beat Leclerc's time but still felt second was a good return for the team.
"It's always difficult to tell, I couldn't do my final run. Either the DRS didn't open or I just lost power," he said.
"It's a bit of a shame, but overall to be on the front row here looking at the whole weekend here, it's a good achievement, but I'd have liked to go for that final run.
"Hopefully, our car will be a bit kinder on the tyres again, but it's difficult to tell at the moment."
Sainz added: "I think everything is possible tomorrow. We are definitely going to try our best to get ahead at the start and lead from there, but it wasn't the ideal qualifying because I couldn't set a good lap on the used tyre."
George Russell was fourth and Lewis Hamilton qualified sixth as Mercedes' record run of nine straight poles in Barcelona came to an end.
Mick Schumacher will start 10th after making it through to Q3 for the first time in his career, while home favourite Fernando Alonso was eliminated in Q1 alongside the two controversially remodelled Aston Martins.
