Bertrand Baguette repeated his morning form to go fastest in the second Formula Renault 3.5 free practice session at Motorland Aragon
With the newly-completed circuit yet to fully rubber in, the Belgian was able to slice 1.7 seconds from his earlier effort.
Chris van der Drift, hunting his and Epsilon Euskadi's maiden win of the season, went second quickest in a session that was interrupted by three red flags. The final stoppage occurred just seven minutes before the chequered flag, shortly after van der Drift had toppled Baguette's best time with a lap of 1m45.273s.
With the clock still counting down, Baguette was afforded just one flying lap to reclaim his position when the session restarted, and responded with a 1m45.053s.
Julian Leal had one of his best showings of the season with Prema to end the day in third, while Comtec's new, all-British pairing of Jon Lancaster and Greg Mansell took fourth and sixth positions, sandwiching early season points leader Marcos Martinez.
James Walker was eighth fastest for P1 Motorsport, and the Jersey driver felt that his plans to overhaul Charles Pic for second in the championship remained on course.
"We have spent the entire day experimenting, and the tyres that I used to set my final lap time were really old in comparison to some others," said Walker. "I think that we are there or thereabouts, I am not saying we have an advantage, but I think we can do our usual job of making Superpole."
"If I can stay ahead of Pic, then I think we should also be able to handle [the threat of fourth placed] Alguersuari.
"The balance of aero is really important here, because the first part of the lap is quite twisty and then you have a very long straight. If you can get it just right I think that there's a big advantage to be had. If you overdrive, you can lose a lot of time."
Among those to cause red flags today have been Salvador Duran, Bruno Mendez and Mansell. Daniil Move was forced to sit out 10 minutes of track time, after the Russian P1 driver was judged to have set a quick lap under reds.
"The first I saw of a red flag was crossing the start/finish line, but I think the officials only looked at the sector times," said Move.

The 2015 Formula Renault 3.5 season will be notable for being the last with the French company's backing but also produced a worthy champion in Oliver Rowland. PETER MILLS evaluates this year's crop of drivers
Last year's field was extraordinary and hard to match, but the Formula Renault 3.5 grid will still have plenty of talent this season. Glenn Freeman runs through the field ahead of this weekend's season opener
Landing the Fortec seat that took rising star Robin Frijns to the 2012 FR3.5 title was already a good sign for Stoffel Vandoorne. Then McLaren took him under its wing. Peter Mills tells Vandoorne's story so far
