GP3 title contender Aaro Vainio set the fastest time in GP3 practice on Friday morning at the Hungaroring, more than four tenths quicker than anyone else.
The flying Finn posted a time of 1m37.396s. Antonio Felix da Costa came closest with his effort of 1m37.819s.
Vainio's Lotus GP teammate Conor Daly was third fastest, just ahead of Marlon Stockinger, who was the last of those to dip below the 1m38 barrier.
William Buller took fifth, ahead of points leader Mitch Evans and the third Lotus car of Daniel Abt. Tio Ellinas was eighth, just ahead of local hero Tamas Pal Kiss. Romania's Robert Visoiu can also claim this as a home race, and he was edged out by Pal Kiss for ninth by just 0.004s.
David Fumanelli was 11th, one thousandth of a second ahead of Hockenheim Race 1 winner Patric Niederhauser. Lewis Williamson was 13th, ahead of fellow Briton Alex Brundle and Matias Laine.
Alex Fontana was 16th on his return to the series with Jenzer Motorsport, ahead of Italian duo Giovanni Venturini and Kevin Ceccon. 19th was Facu Regalia, who has switched to Atech CRS GP this weekend after racing for Jenzer at Silverstone.
Fabiano Machado was 20th as he returned to the track after his heavy landing in Hockenheim, ahead of Alice Powell and Vicky Piria – another who required medical attention in the second race in Germany but escaped injury. Robert Cregan, Dmitry Suranovich, Ethan Ringel and Carmen Jorda completed the 26 runners.
Qualifying takes place at 08:45 BST on Saturday morning.
