Typically changeable weather conditions produced an exciting pair of GP3 Series races at Spa-Francorchamps, with Robert Wickens and Adrien Tambay taking a win each.

Saturday's Race 1 began in dramatic style as several cars collided at the first corner. Status driver Wickens was leading the field when on Lap 4 parts of the track were hit by torrential rain. As he crossed the start-finish line he started to lose control of the car on the standing water and spun into the pit wall, knocking off his nose cone. All of the other cars behind him were struggling for grip, many spinning and hitting each other. Wickens managed to retain the lead as the safety car was deployed and opted to stay on slicks as most of the field pitted for wet weather tyres. When the safety car came in the race was reaching its time limit, so Wickens slowed the field down enough to cross the line just as the clock ticked to zero.

A rain shower hit the circuit in the middle of Race 2 on Sunday morning, and as most of the field pitted for wet tyres Manor's Tambay, who had started 27th, stayed out to earn himself a 10 second lead. As the wet-shod cars, led by ART's Alexander Rossi, closed in on Tambay with three laps to go, the circuit was drying. This allowed Tambay to hold on to take his first GP3 win.

Rossi's second place gave ART the team's title. Series leader Esteban Gutierrez holds an 18 point lead over Wickens in the drivers' standings ahead of the final race weekend in Monza.
