Christian Vietoris, Spa, 2011Christian Vietoris claimed pole position by a massive 1.4sec in a wet GP2 qualifying session at Spa on Friday.

The Racing Engineering driver was the early pacesetter in the session, and he remained in the thick of the fight for pole throughout. In the final minute of qualifying, he knocked Luca Filippi (Coloni) off the top spot, but his pole position could be in doubt as yellow flags were waving at Blanchimont when he set his fastest lap.

Those flags were out for Addax's Charles Pic, who had pulled over and stopped on the exit of the left-hander. The Frenchman ended the session with the third-fastest time.

ART driver Jules Bianchi recovered from a low-speed spin at Les Combes to complete the second row of the grid, while Coloni's Michael Herck continued his good form from practice to take fifth, having been a factor at the front throughout qualifying.

Marcus Ericsson (iSport) and Adam Carroll (Super Nova) were next up, with championship leader Romain Grosjean – who could clinch the title this weekend – only eighth for DAMS as he struggled to get a clear lap when the track improved in the second half of the session.

He is still ahead of his main title challenger, though, as Giedo van der Garde (Addax) could only manage 11th on the grid. If Grosjean can extend his points lead over the Dutchman by two points on Saturday, he will seal the title.

Of 2011's usual front runners, Sam Bird had the worst session. The iSport driver had a similar spin to Bianchi's at Les Combes, but unlike the Frenchman he could not avoid contact with the barrier and will start 22nd.
