Romain Grosjean comfortably led the way in the first GP2 practice session of the weekend at Barcelona.
The championship leader was the first driver to set a genuine lap time six minutes into the session, and his best effort of 1m30.559s was never headed. In fact, none of the Frenchman's rivals could even get within half a second of his time.
All of the quick times were set shortly after Grosjean made his mark, with Davide Valsecchi (AirAsia) and Jules Bianchi (ART) leading the chase. But the session came to a quiet end, as nobody in the top 10 improved in the final 15 minutes.
Addax's Giedo van der Garde overcame a very public on-track row with Rodolfo Gonzalez to set the fourth fastest time, while Luca Filippi completed the top five for Super Nova.
Charles Pic made sure Addax had two cars in the top six, ahead of Fabio Leimer (Rapax) and Grosjean's DAMS team-mate Pal Varhaug.
Sam Bird, who shares the championship lead with Grosjean coming into this weekend, did not hit the same heights as his rival and was only 24th. The iSport driver completed plenty of laps, unlike the two Arden cars that also finished the session near the back, but he could not improve on a best lap that was 2.9 seconds adrift.
