2010 Catalunya GP2 Series round

The rookie Frenchman moved into first place when previous leader Sergio Pérez (Barwa Addax) was delayed by a slow pitstop, and survived a brief challenge from DPR's Giacomo Ricci to take Arden's first win since the same event 12 months ago.

Less fortunate in his progress through the field was Barwa Addax's Giedo van der Garde, who was dealt a 10s penalty for leaving the pit exit after it had closed prior to the race, and then a drive-through for jumping the start.

ART's Sam Bird echoed his overtaking masterclass of the day before with another excellent performance, the Briton climbing from ninth to fourth, and he could potentially have challenged for third were it not a late excursion into the gravel that cost him six seconds.

Once again it was a difficult day for some of the series favourites, with Jules Bianchi finishing 12th after banging wheels with Giedo van der Garde and sliding off the track, while Sergio Pérez was unable to make the start after the engine in his Barwa Addax Dallara blew on the formation lap.

There could be more bad news ahead for the Mexican, who is facing a post-race investigation for trailing oil around the racing line on two thirds of the lap before finally pulling over, forcing the start to be delayed by 10 minutes while powder was laid down.
