Jimmy Eriksson managed the best time in a rain-affected afternoon session on day one of GP3 pre-season testing at Estoril.
Eriksson, who joined Koiranen for the 2014 season after the Russian Time’s GP3 entry collapsed, set a time of 1m29.183s early in the session prior to the rain. That put him 0.038s slower than the morning benchmark of Dino Zamparelli, who was 23rd of the 24 drivers in the afternoon standings.
Marussia Manor recruit Dean Stoneman was second, 0.599s slower than Eriksson. German F3 champion Marvin Kirchhofer took third for ART.
Fourth was single-seater returnee Richie Stanaway for Status Grand Prix ahead of GP3 debutant Alex Lynn (Carlin). Santiago Urrutia was sixth for Koiranen ahead of Arden’s Robert Visoiu, with Luis Sa Silva (Carlin), Patrick Kujala (Marussia Manor) and Nick Yelloly (Status) completing the top ten.
