Lewis Williamson has recorded the quickest time on the first day of the official GP3 Series test at the Hungaroring, as his MW Arden team topped both sessions. In the morning session, Michael Christensen set the early pace for RSC Mucke Motorsport, until Arden's teenage New Zealander Mitch Evans knocked him off top spot in the middle of the session. His time remained good enough to finish the morning on top, with Christensen staying second.
 Nico Muller was third quickest for Jenzer Motorsport, with Lotus ART teammates Valtteri Bottas and James Calado ending up fourth and fifth. Antonio Felix da Costa was just three thousandths off Calado in sixth place for Status Grand Prix, ahead of Barcelona race winner Tamas Pal Kiss (Tech 1) and Addax's Gabby Chaves. Williamson and Adrian Quaife-Hobbs rounded out the top ten as the quickest 17 drivers were covered by just one second.
 
In the afternoon, championship leader Nigel Melker held top spot for Mucke for the first half of the session, before Muller took his turn at the top of the timesheets. In the final hour the drivers switched to fresh Pirelli tyres and a battle for the top spot ensued. Chaves was the first man to take first place, before he was dethroned by Williamson. Quaife-Hobbs had a brief spell on top but Williamson regained his place before the end of the session, setting the quickest time of the day.
  
Alexander Sims took second for Status, pushing Quaife-Hobbs down to third. Calado was fourth, making it an all-British top four. Tom Dillmann, who is returning to GP3 for the rest of the season with Addax, was fifth. Felix da Costa was sixth again, ahead of Mucke teammates Christensen and Melker. Bottas and Tech 1 driver Aaro Vainio completed the top ten.
