GP3 graduate Juan Manuel Correa denied European Formula 3 champion Mick Schumacher the top spot with a last-gasp lap in Abu Dhabi Formula 2 testing on Friday.
Correa, who scored a best result of fourth place in his first full GP3 season this year, switched to Charouz Racing System for Friday's F2 running after testing with MP Motorsport on Thursday.
Schumacher, in action for the Prema Racing team that has run him through Formula 4, F3 and has already announced him as part of its 2019 F2 line-up, inched ahead of experienced F2 driver Luca Ghiotto by 0.002 seconds to hit the front when the test resumed with 23 minutes remaining after a red flag.
But Correa was able to outpace Schumacher by two tenths of a second late on to end the day fastest.
Ghiotto ended up third ahead of fellow series regular Sergio Sette Camara, running with likely 2019 team DAMS, and Carlin's returnee Nobuharu Matsushita.
GP3 champion Anthoine Hubert had caused the late red flag with a spin but set the morning pace for MP.
Jack Aitken, in second for Charouz, was the only 2018 F2 driver in that session's top six.
Giuliano Alesi, Dorian Boccolacci and Leonardo Pulcini were third, fifth and sixth, with F3 convert Guan Yu Zhou fourth.
In the day's GP3 sessions, series regular Niko Kari's morning time for Trident stood as fastest. Jehan Daruvala was his closest rival in the morning and led the afternoon.
