Antonio Felix da Costa dominated the second day of Formula Renault 3.5 testing at Paul Ricard on Saturday, leading the way by half a second.
The Red Bull junior driver came out on top in a frantic finish to the test, as teams closed out their running in France with qualifying simulations.
Arden Caterham driver da Costa had also led the way in the wet morning session, where his best lap was one second clear of his closest challenger.
FR3.5 rookie Stoffel Vandoorne, who had topped both of the pre-season test days so far this year for Fortec, ended the day second, just ahead of Arthur Pic and Kevin Magnussen. Sam Bird, who was brought in for this test to help ISR's 2013 preparations, rounded out the top five.
The Briton had shone in the morning, managing the fourth fastest time despite completing around one third of the laps of most of the other front-runners.
Marco Sorensen was next up, while Draco teammates Nico Muller and Andre Negrao were together in the order for the second day running to complete the top eight.
