Fortec Motorsport's Sten Pentus took his maiden Formula Renault 3.5 pole position with a late effort at the Hungaroring
The Estonian jumped up the order from 12th place in the final seconds of the half hour session.
Pentus edged out reigning Formula Renault 2.0 Eurocup champion Albert Costa by 0.112 seconds. The Spaniard's final sector was a full second slower than the polesitter's time, leaving his Epsilon Euskadi team boss Joan Villadeprat frustrated.
"We are a bit upset. Not because Albert made a mistake, but because we have wasted the whole weekend going back and forth with the set-up," said Villadelprat. "Eventually we said, 'look we know this set-up works, this is what you are using,' and in the first race he went from 16th to sixth. He thought he was a hero, but we were wondering why he couldn't do that on Friday.
"I think Albert is the fastest driver in the pitlane. If I didn't think he had potential, I wouldn't be annoyed. Today his first sector time was astonishing. He was already fastest and then on his next lap his first sector was four tenths up on his own best. The mistake, though, is the third time this year that we've lost pole."
Daniel Zampieri, who struggled for race pace on Saturday, had a much more competitive showing with today's high downforce settings and took third place for Pons Racing.
Comtec also returned to form having shelved the low-downforce aero configuration (LAC) that is mandatory during Saturday races. Greg Mansell achieved his best grid position of the year with fourth. The Briton had made several good overtaking manoeuvres in race one, before a coming together with KMP's Victor Garcia. He had initially feared that damage from the incident could hamper his pace today.
Championship leader Mikhail Aleshin ended the morning in fifth, and will be joined on the third row by the second Comtec entry of Stefano Coletti, who retired in race one with a broken fuel pump.
Saturday winner Daniel Ricciardo had commented that his dominant display in race one might not translate into a similar performance with today's set-up. The British Formula 3 champion will be disappointed to have been proven correct after qualifying in seventh place for Tech 1 Racing.
