Renault junior driver Christian Lundgaard topped the second and final day of FIA Formula 3 testing at Paul Ricard for ART Grand Prix, ending the series' first official test session.
The morning provided the top 12 fastest times, with 2018 Formula Renault Eurocup runner-up Lundgaard seting a lap of 1m48.786s.
His time was 1.829s quicker than Dorian Boccolacci's pole time at the same track in GP3 last year.
Lundgaard did stop at the pitlane entry, but was able to get back out on track to set the session best.
Marcus Armstrong was second quickest having topped the times on the first day of the test for Prema Racing on Wednesday.
Hitech GP's Leonardo Pulcini - who was the runner-up on Wednesday - took third.
Prema had two cars in the top four with Armstrong's team-mate and fellow Ferrari junior Robert Shwartzman in fourth, ahead of a second Hitech-run car of Yifei Ye.
The top five were the only drivers to dip into the 1m48s range at the Le Castellet track.
After missing yesterday's session through engine trouble, Jake Hughes was the highest-placed HWA car and set the ninth-fastest time in the morning and completed 78 laps.
Pedro Piquet - son of three-time Formula 1 champion Nelson - lapped the most number of times with 100 laps for Trident.
Yuki Tsunoda, pictured above, topped the afternoon session for Jenzer Motorsport, but his time was only good enough for 13th overall on the day.
The series will test again at Barcelona on April 9-10, then at Budapest on April 17-8.
The FIA F3 season kicks off at Barcelona on May 10-12.
