Alexander Sims returned to the grid, this time for Carlin. He replaced Eric Lichtenstein, whose contract was terminated for non-payment.
MW Arden locked out the front row of the grid for race 1, with Carlos Sainz Jr. beating Daniil Kvyat to take his first pole position. Kvyat got a better launch than Sainz, taking the lead into La Source. The first of three safety cars was called on the opening lap when Emanuele Zonzini and Josh Webster collided at turn one. On the restart, Adderly Fong and Patric Niederhauser also crashed in turn one. Then, with four laps remaining, Jack Harvey collided with Sainz, the impact with the barriers splitting Harvey's car in half. The race ended under safety car, with Kvyat taking his first win of the season.
Tio Ellinas started from pole for race 2. Sims had a good launch from fourth on the grid, taking the lead into turn 1 as Ellinas and Melville McKee collided. Sims pulled an eight-second gap over Conor Daly and Facu Regalia to win the race. Another weekend of poor results for Ellinas meant Regalia took the lead of the championship, fourteen points ahead of Daly.
