Antonio Felix Da Costa posted the fastest time in GP3 free practice as the British Grand Prix weekend got underway at Friday morning at a wet Silverstone circuit.
After getting in some wet-weather practice on his debut as a Red Bull Junior in the Formula Renault 3.5 Series at the Nurburgring last weekend, Felix Da Costa traded fastest times with Tamas Pal Kiss throughout the session.
Carlin's Felix Da Costa improved at the very end to finish up 0.373 seconds clear of Atech CRS GP driver Pal Kiss.
Mitch Evans comes into the weekend four points clear at the head of the standings, and he also took his turn at the top of the timesheets during the session. The MW Arden ace finished up third, 0.845 seconds off Felix Da Costa.
Fresh from victory in the reverse grid race at Valencia, rookie Patric Niederhauser was fourth for Jenzer Motorsport. Evans' title rival Aaro Vainio was fifth, nearly two seconds off Felix Da Costa's time and just 0.035s ahead of his Lotus GP teammate Conor Daly.
Kevin Ceccon took seventh for Ocean Racing Technology ahead of the locally-based team Status Grand Prix's leading driver Marlon Stockinger.
Three seconds off the pace was ninth-placed Tio Ellinas of Marssia Manor Racing, narrowly ahead of Carlin's Alex Brundle.
Matias Laine was 11th for MW Arden, ahead of the third Carlin driver William Buller and the third Lotus driver Daniel Abt.
Giovanni Venturini was the fastest of the three debutants, driving the GP3 car for the very first time and ending up 14th and the best of the Trident Racing cars.
Fellow Italian David Fumanelli was 15th after ending up in the gravel, with Antonio Spavone 16th. Facu Regalia was 17th in his first session for Jenzer Motorsport, ahead of Vicky Piria and Kotaro Sakurai – the Japanese driver returning to the fold this weekend for Status after missing out in Valencia due to budget issues.
Dmitry Suranovich was 20th, ahead of the final debutant Fabio Gamberini. He was 1.6 seconds clear of his new Atech teammate Ethan Ringel. Robert Visoiu and Alice Powell ended their sessions early in the gravel and subsequently finished up 23rd and 24th.
