Lewis Hamilton qualified quickest for the Turkish Grand Prix on Saturday, but a 10-place grid penalty for the Formula One championship leader meant Mercedes teammate Valtteri Bottas took pole position.
Hamilton's title rival Max Verstappen, two points behind the Briton with seven races remaining, qualified third for Red Bull and will join Bottas on the front row at Istanbul Park on Sunday.
The pole was a first since Portugal in May for Bottas, and the 18th of his career, but Hamilton was fastest in every phase of qualifying after taking the hit for a new engine that exceeded his season's allocation.
"Tomorrow is going to be difficult, but I'll give it everything," said Britain's seven times world champion Hamilton of the task ahead.
"We've got the long straight down the back, we'll see what we can do. Hopefully, we can give the fans here a good race."
Verstappen took a grid penalty at the previous race in Russia and finished second after starting at the back of the field, his progress helped after late rain caused problems for others.
Mercedes will be looking to Bottas, who is leaving the team for Alfa Romeo at the end of the season, to keep Verstappen behind him while Hamilton sets about fighting through from 11th.
"I'll focus on my own race tomorrow, that's the way to go when you start in front and try to keep up a good pace," said the Finn.
Verstappen struggled with the setup in Friday practice, with the track far grippier than last year's slippery surface, but said the team had made "a decent recovery.
"Tomorrow, lining up in second, let's wait and see what the weather will do, but overall I'm pretty happy," said the Dutch 24-year-old.
"Let's see how competitive we will be in the race. The tyre wear seems quite high around the track, but it's quite fun to drive."
Ferrari's Charles Leclerc will share the second row with AlphaTauri's Pierre Gasly, who will be expected by Red Bull to make life difficult for Hamilton as a driver for their sister team.
Double world champion Fernando Alonso, for Alpine, and Verstappen's Mexican teammate Sergio Perez line up together on row three and will also be hard to get past.
McLaren's Lando Norris, on pole in Russia and leading until the final laps, was eighth fastest and starts seventh with Lance Stroll alongside Aston Martin.
Hamilton will also have to get past AlphaTauri's Yuki Tsunoda and four times world champion Sebastian Vettel's Aston Martin.
Further back, Mick Schumacher got his Haas into the second phase with an impressive lap and lines up 14th for the only team yet to score a point this season.
McLaren's Australian Daniel Ricciardo, winner of the Italian Grand Prix at Monza, qualified 16th with Ferrari's Carlos Sainz keeping him out of the second phase right at the end.
Sainz, who starts at the back of the grid due to an engine change, also gave teammate Leclerc a useful aerodynamic tow to help the Monegasque into the final phase.
