In the supporting Indy Lights, the title was decided on a tie-break after two wins for Jack Harvey. That wasn’t quite enough for the British rookie, who lost out to the more consistent Gabby Chaves after the pair tied on points.

The GP2 title battle is alive and well. Felipe Nasr continued to erode Jolyon Palmer's points lead at Spa, and despite a consistent weekend from the Brit there's still everything to play for.

Raffaele Marciello won the Feature Race after a fantastic duel with local hero Stoffel Vandoorne, both men proving that rookies can impress in GP2. Johnny Cecotto was third after briefly leading early on.

Nasr won the Sprint Race after a blistering getaway from fifth on the grid. Cecotto pushed him hard but the Brazilian always seemed to have an answer. Palmer was third and now leads Nasr by a reduced 32 points with three race weekend remaining.

Belgium 2014 GP2 podium

A frantic and sometimes strange GP3 Feature Race was won by Dean Stoneman, who led a British sweep of the top four ahead of Dino Zamparelli, Nick Yelloly, and Jann Mardenborough. The contest should have been won by Matheo Tuscher, but the 17-year-old Swiss spun out of a comfortable lead with only a few laps to run.

Championship leader Alex Lynn and title rival Richie Stanaway were seventh and eighth after making the wrong tyre call, but that put them one-two for Sunday's reverse-grid Sprint Race. They delivered, taking a one-two in Lynn's favour after an intense mid-race scrap.
