Markus Pommer turned the tables on Matheo Tuscher by taking pole position for Sunday's FIA Formula Two race at Paul Ricard.
Tuscher had beaten the German to pole on Saturday and gone on to win the race, but this time Pommer put in a quick final lap to beat the teenager by 0.139 seconds.
“Yesterday I didn’t get a good start and nearly stalled so I’m hoping for better today,” said Pommer. “My race pace was off yesterday and my front tyre was blistered which made it un-driveable but for today we made a better and smoother set up which made the car feel good and now I’m optimistic for the race.”
Tuscher said: “I’m happy to be second today. My qualifying wasn’t that good as I got blocked in the first corner by another driver and in my next run I made a huge mistake so I’m happy to come away with P2 and I’m looking forward to the race.”
Christopher Zanella was three tenths away from Pommer in third place, narrowly ahead of Kevin Mirocha. Dino Zamparelli set himself up for another good result with fifth place, edging out fellow Englishman and championship leader Luciano Bacheta by just 0.002s.
Mihai Marinescu was seventh, while Plamen Kralev was a career-best eighth and only seventh tenths off pole. Alex Fontana was ninth, with Daniel McKenzie a lowly tenth after finishing third in Saturday's race.
The second race of the weekend takes place at 13:30 BST.
