British driver Will Buller was fastest on the test day of the Aragon Formula Renault 3.5 Series weekend. The Arden Motorsport driver set a lap time of 1:41.222s just as the chequered flag fell to oust Spaniard Carlos Sainz Jr of DAMS by the merest margin of 0.035s.
Buller’s team-mate Pierre Gasly was third quickest in a session where all twenty-one cars were covered by 1.027s. Zeta Corse driver Roberto Merhi, who surprised many by grabbing a podium finish in Monza two weeks ago, continued his good form by setting the fourth fastest time of the day, just ahead of Nikolay Martsenko in the sole Comtec Racing entry. Comtec, ISR and Tech 1 Racing are still only fielding one car in Aragon like they did in Monza, while Carlin remain absent. It means the field is once again set at 21 cars.
The leading Fortec Motorsport entry of Sergey Sirotkin was sixth fastest, and his lap time was 0.001s slower than that of Martsenko ahead of him. Seventh went to the Lotus of Marlon Stockinger, with Jazeman Jaafar of ISR just behind him in eighth. The top ten was rounded out by Strakka Racing’s Will Stevens, who won the opening race of the season in Monza, and by Oliver Rowland in the second Fortec Motorsport machine.
Stevens had topped the morning session ahead of Gasly and Buller, but all signs point to the weekend being a close-run affair. Qualifying for race one will take place tomorrow morning, with Sainz Jr aiming for three-in-a-row after taking both pole positions in Italy.
