Carlin Motorsport’s Alex Lynn ran quickest in both the morning and afternoon sessions on day two of the first GP3 pre-season test at Estoril.
The Red Bull junior driver settled upon a best lap of 1:28.552 in the latter part of the day, after settling upon a 1:29.2 in the morning.
A heavy downpour the previous night ensured a damp and green surface for the 24 runners, leading to a brief spin for Visoiu as the track slowly dried.
As the slick tyres emerged, some competitive times registered with Yelloly once again heading the pack, before Bernstorff and Marvin Kirchhöfer broke the 1:30s barrier. A brief red flag gave the drivers a quick breather in the lead up to lunch, but not before Lynn lowered the benchmark significantly.
Plenty of red flags interrupted the start of the afternoon session, with Eriksson, Melville McKee and Santiago Urrutia all falling off track at various points. Despite further charges from Bernstorff, Luis Sa Silva and Roman de Beer, Lynn went quicker still to end the first session on top.
The next session runs at Jerez from April 10-11.
