Daniel Abt continued his fine form as the ART driver ended the Valencia GP3 test on top of the times.
The 18-year-old German, who competed in the F3 Euro Series this year, set the pace in 1m26.147s during the morning session, a time good enough to knock Manor driver Matias Laine off the top spot by just 0.075sec. Marlon Stockinger put his Status car third, ahead of Jenzer's Patric Niederhauser and Atech CRS driver Tamas Pal Kiss, a race-winner in GP3 with Tech 1 this year.
James Calado, who finished second in this year's championship, but is moving up to GP2 with ART in 2012, drove for the squad and was sixth quickest.
Conor Daly headed the afternoon times for Carlin, but with track conditions being less conducive to quick laps and most teams turning their attentions to race simulations, this failed to help him improve on his seventh place overall.
Maxim Zimin (MW Arden), Michael Heche (Jenzer) and Aaron Vainio (ART) completed the top 10, while British drivers Will Stevens and Tom Blomqvist were 14th and 15th for the MW Arden and Carlin squads respectively.
Japanese F3 champion Yuhi Sekiguchi crashed his RSC Mucke car during the morning session and was unable to get out during the afternoon.
