Adrian Quaife-Hobbs extended his Auto GP World Series points lead with a fourth victory in the ninth race of the season in Portimao.

The Kent racer started from his fourth pole position of the season, but lost the lead at the start to Argentine Facu Regalia. Super Nova man Quaife-Hobbs quickly fought back though, using the boost to regain P1 at the end of the lap.

From there he gradually pulled away, winning with an advantage of nine seconds. His nearest championship rival Pal Varhaug would finish in second place, the Norwegian just about keeping Russian teenager Sergey Sirotkin behind.

Sirotkin launched from sixth to third at the start and then took second from Regalia on lap three when the latter ran wide. An early stop on lap four by Varhaug's Virtuosi crew however meant that he had the opportunity to run in clean air and get his tyres up to temperature, meaning he got ahead of Sirotkin shortly after the Euronova driver made his stop.

Quaife-Hobbs' teammate Victor Guerin returned from his GP2 escapades to finish fourth after a race-long duel with Sergio Campana. Regalia lacked pace after his start and slumped to sixth, ahead of the Manor MP duo of Daniel De Jong and Chris van der Drift. Newcomer Juan Carlos Sistos was ninth for Zele Racing, with Giancarlo Serenelli completing the top ten.
