Rodin Motorsport's Gianmarco Pradel set the quickest time in Free Practice Two at the Hungaroring, but fell just short of beating teammate Alex Ninovic's effort from this morning's session.
Australian Pradel set a time of 1m38.350s in the closing stages of the 45-minute session, though a late red flag ended the chances of any further improvements in the final two minutes. Pradel's time was 0.112s away from Ninovic's FP1 effort.
Ninovic was second in FP2 to underline his pace this weekend, with Hitech TGR's Deagen Fairclough third having also topped the times inside the final few minutes. Fairclough was half a tenth behind Ninovic and 0.145s clear of teammate Keanu Al Azhari in fourth.
Will Macintyre was the lead Elite Motorsport runner in fifth, 0.053s in arrears of Al Azhari and 0.163s ahead of Xcel Motorsport's Patrick Heuzenroeder, who was sixth fastest for the second successive session.
VRD Racing's Hugo Schwarze moved up to seventh having been ninth this morning, and 0.020s clear of JHR Developments' Noah Lisle.
Rodin's Abbi Pulling and Xcel Motorsport's Jack Sherwood completed the session two top-10, which was covered by 1.019s.
The vast majority of drivers set their best times of the day in FP1, with Ninovic and Macintyre the top-two on the combined times, though Pradel's afternoon effort moved him above Al Azhari into third.
Fairclough was another to improve in the afternoon and was fifth overall ahead of Lisle, with Heuzenroeder ahead of Argenti with Prema's Reza Seewooruthun. Schwarze and Pulling completed the top-10.
Ninovic's best time of 1m38.238s is 1.391s quicker than last year's pole lap in the previous generation GB3 car.
GB3 action at the Hungaroring really kicks into gear tomorrow morning, with the two-part qualifying session commencing at 10.50 local time (09.50 UK).
