Esteban Ocon clinched a crucial pole for the opening race of the Abu Dhabi GP3 season finale, taking the championship lead from Luca Ghiotto by two points.
ART Grand Prix's Ocon had set the early pace before Kevin Ceccon and Jimmy Eriksson went quicker than the Frenchman.
But the Mercedes junior came back and went 0.337s ahead of Eriksson after 10 minutes.
It was then Trident driver Ghiotto who headed the timesheets, his lap of 1m55.634s putting him 0.417s ahead of Ocon, albeit only after appearing to exceed track limits.
For the final runs, Ceccon took provisional pole before Ocon lapped in a 1m55.491s, going a mere 0.016s ahead of the Italian driver to take his third straight GP3 pole and the championship lead.
Ceccon finished second ahead of Marvin Kirchhofer with Ghiotto only managing fourth, after losing crucial time in the final sector.
The top four were separated by only 0.088s, while the top 16 were within a second of the polesitter's time.
Eriksson was fifth ahead of Emil Bernstorff, while a fast looking Antonio Fuoco only finished seventh in an incident-free session.
The top 10 was rounded by Alex Palou in eighth, Matt Parry ninth and Artur Janosz 10th.
