George Russell set the fastest time of the first day of pre-season   testing at Circuito do Estoril during this afternoon’s session, stopping  the clock at 1:27.606, less than a tenth ahead of teammate Nirei Fukuzumi and Raoul Hyman.

The GP3 paddock was greeted by rays of sunshine on the morning of Day  2 of pre-season testing, but grey clouds made their way over the   Portuguese track minutes before the pitlane turned green. As the cars fed onto the track, rain drops fell from the sky and the session was soon declared wet.

The pitlane opened in wet and windy conditions as the cars fed onto the track. After the traditional installation laps, Santino Ferrucci topped the timing sheets. Halfway through the session, most drivers had set a laptime with Steijn Schothorst the quickest man on track in a 1:43.764.

The rain intensified forcing the cars back into the pits to wait for more lenient weather. As the sun made a timid comeback, the proceedings  resumed. With one hour left on the clock, Russell went top ahead of   Fukuzumi. Their teammate Jack Aitken pipped the Japanese driver to move up to P2, with Anthoine Hubert in P4 making it an all ART top four. But  as the clock ticked down, Niko Kari went quickest with a laptime 0.6s quicker than Russell.

In the final stages, on an improving track, the Briton reclaimed the top spot but Alessio Lorandi dipped under 1m38s to take top honours   ahead of Schothorst. As all other drivers remained on wet weather tyres,  and the top spot kept changing hands, Hyman judged the track to be dry  enough for slicks. Just before the flag dropped, he blew past Niko Kari  setting a laptime 5.3s better than the Finn.

The track was dry as the afternoon session started. Fukuzumi set the early pace but it was Leonardo Pulcini who sat pretty at the top of the timesheets as the proceedings were briefly halted on the 50 minute mark  after Russell stopped at Turn 2.

At the restart the session was very busy, with the teams and the   drivers getting to grips with the newly added DRS device: Alessio Lorandi claimed the top spot before Arjun Maini pipped him with one hour  left on the clock. Fukuzumi was the first man to dip under 1m28s, but so did Russell who lapped the Portuguese track 0.079s faster than the Japanese ace.

At the chequered flag, Russell led Fukuzumi and Hyman. Hubert, Maini,  Giuliano Alesi, Dorian Boccolacci, Aitken, Kari and Ferrucci rounded out the top ten.
