Oliver Turvey and Brendon Hartley secured a victory apiece for Carlin as the British F3 International made its annual visit to Belgium for the latest rounds of the season.
Trevor Carlin's eponymous team dominated proceedings at Spa, leading the way through practice and qualifying before securing victory in both twelve lap races.
Turvey had qualified on pole position for the opening race and managed to lead for almost the entire run around the Ardennes venue as he headed Hartley to the flag to the flag. Hartley has briefly got ahead off the line only for Turvey to reclaim the lead into Les Combes and the Racing Steps Foundation-backed driver wasn't headed from that point on as he secured victory.
Hartley took second ahead of Jaime Alguersuari, while Sam Abay completed 1-2-3-4 for the Carlin squad with fourth place having battled his way back up the pack after dropping down to sixth at the start.
"Brendon managed to get past me at the start and we were side by side into Eau Rouge, and then I managed to slip stream him through Les Combes and get back into the lead," Turvey said. "From there on it was a matter of controlling the race as I felt I was quick enough to win. We really had the pace, Carlin Motorsport have done a fantastic job and given us a great car all weekend."
Race two ended in early disappointment for Turvey who had once again qualified on pole but was left stuck on the grid when the lights went out due to an engine problem.
Behind Turvey, Abay just managed to avoid his team-mate off the line and found himself immediately in a battle with Marcus Ericsson. Contact between the two at the first corner resulted in a puncture for Abay, who had a long drive back to the pits that dropped him to the back of the field – although he displayed his pace with the second quickest lap of the race.
It left Hartley and Alguersuari to uphold honours for the team and Hartley battled his way through from fifth place to secure victory after storming past Sergio Perez on the final lap. Alguesuari meanwhile took the flag just off the podium in fourth.
"Sam and Marcus had a bit of a coming together into the first corner, and I lost a lot of places trying to avoid that, but then I had the car to be able to push and get the places back," Hartley reflected. "I worked really hard with my engineer after the first race and the car felt great today, I have to say the car was doing all the work for me. I have to thank the team, they've worked so hard since the last race at Brands Hatch and the car has been fantastic all weekend.
"I really enjoyed racing with Sergio, he's a very fair racer and left me just enough room to make the move. I'm pleased to have put myself back in the running for the title. I think there will be probably be four or five drivers in with a chance of winning, so it's going to be an exciting end to the season."
