Canadian racer Nicholas Latifi set the quickest time in the first practice session of the British F3 round at Spa, which remained the lap to beat until the very end of the Carlin-dominated day of running.
Latifi cleared the rest of the field by 0.7s in the morning practice run, taking first ahead of his teammates Jordan King and Jann Mardenborough. He failed to improve on his time in session two, going only 0.007s slower than King’s session-topping time as Mardenborough posted the third time again, just 0.01s slower than King.
Silverstone race winner Antonio Giovinazzi was fourth in both practice sessions, failing to match the pace of the Carlin cars but easily placing himself above the rest of the field. His teammates Tatiana Calderon and Sean Gelael rounded out the top five in morning and afternoon practice respectively, while the Fortec cars struggled as both championship leader Will Buller and Felipe Guimaraes had to settle for a best place of sixth in the session timesheets.
In the National class, Sun Zheng topped both practice runs.
