Ferrari's Sebastian Vettel says he expects a challenge from Mercedes at the Singapore Grand Prix despite their struggles in qualifying.
Lewis Hamilton and Nico Rosberg were fifth and sixth, ending a run of 23 poles for Mercedes, as Vettel took Ferrari's first pole since July 2012.
He said: "I wouldn't rule them out for the race. They must have some issues.
"It's not the easiest to overtake but if you have the pace you come through. So I expect them to be strong."
Vettel is joined on the front row by Red Bull's Daniel Ricciardo, with the Ferrari of Kimi Raikkonen and Red Bull's Daniil Kvyat third and fourth.
Hamilton said he still hopes to be able to fight for a victory that would make his career record equal to that of his idol Ayrton Senna - 41 wins from 161 grands prix.
'It's exciting to have this kind of fight'
Hamilton, who heads into Sunday's race (at 13:00 BST on the BBC Sport website and on Radio 5 live) with a 53-point championship lead over Rosberg, said his goal for the weekend remains unchanged.
"I'm just going to approach it the same as I do every race - I want to win," he said.
"There's no reason you can't win it from fifth but the guys ahead have been quick all weekend and you've got to assume that's going to be the same tomorrow, but I go ahead with the mentality of trying to win still."
Hamilton said Mercedes' problems were down to a lack of grip from the tyres.
"I don't know really what we got wrong," said Hamilton.
"To be honest, it's exciting to have this kind of fight. It was the first time having to go into qualifying trying to pull even more out of the car, and therefore sometimes making mistakes, so it was really challenging.
"But for some reason the tyres weren't working; you warm up the tyres like everyone else and then you finish your lap and you see someone else a second up the road."
Vettel said he was surprised by Mercedes' lack of pace, adding that when he saw them struggling in practice he suspected they were disguising their potential.
"I thought yesterday they were sandbagging and also this morning, because there's no doubt they have the strongest package this year," the four-time champion said.
"They have a very good car, sorry, a very good power unit, which we know. It usually puts them very high up and difficult to beat."
Ricciardo, meanwhile, said a victory for him was "not impossible", adding: "We put ourselves in the best position for it.
"If our long runs from yesterday are any sign, then, yeah, we've got a chance. I'll be going for it. We haven't been this far at the front for a long time, so I will try to capitalise."
Singapore GP is a modern classic
Singapore has been on the Formula 1 calendar only since 2008, but already it has become a modern classic.
The key was to hold the street race in the south-east Asian city state at night.
The combination of futuristic skyscrapers across the cityscape, colonial buildings lining the circuit and the lighting on the paintwork of the cars is stunning.
The tight and twisty track does not always produce the greatest race, but as a challenge it is among the toughest in the sport - the combination of tropical heat and humidity, the bumpy track and the longest event on the calendar tests the drivers to their limit.
