2013 Macau Grand Prix winner and new Red Bull junior driver Alex Lynn topped the times of the final day of the first GP3 pre-season test in Estoril. The British driver set a best lap time of 1:28.553s to beat Carlin team-mate Emil Bernstorff into second place. The two Carlin drivers were the only two drivers to set a lap time under 1:29s. Swedish driver Jimmy Eriksson completed the top three in the Koiranen GP entry, but was over seven tenths of a second behind pace-setting Lynn.
South African Roman de Beer impressed for Trident Racing, ending the day an impressive fourth place, finishing just ahead of the third Carlin entry of Angolan Luis Sa Silva. Former Formula 2 champion Dean Stoneman ended the day sixth fastest for his new Marussia Manor Racing team. Alex Fontana, Dino Zamparelli and Marvin Kirchhofer ended the day in seventh, eighth and tenth for ART Grand Prix, with Nick Yelloly ending ninth for Status Grand Prix.
The day began wet after overnight rain, and Robert Visoiu in his Arden International machine span and stopped on track causing the first red flag of the day. Midway through the morning session, it was dry enough for the teams to bolt on the dry tyres to their cars, and it was Lynn who set the pace, his morning time of 1:29.266s again placing him just ahead of Bernstorff. The top five of the morning session were all Brits, with Zamparelli, Melville McKee and Yelloly behind the two Carlin cars. Zamparelli caused two red flags in the session, the second of which came ten minutes before the scheduled end of the session.
McKee, Eriksson and Santiago Urrutia all spun into the Estoril gravel traps, causing the other red flags of the day in the afternoon session.
The second pre-season test will take April 10th-11th at the Circuito de Jerez in Spain, and will see the first appearance of the Hilmer Motorsport GP3 team, who missed this test due to the late announcement of their participation in the series.
