Valtteri Bottas was fastest in both the morning and afternoon sessions on the second day of the GP3 Series pre-season test at Barcelona's Circuit de Catalunya.
The ART driver went to the top of the timesheets just twenty minutes into the morning session. He then put in a succession of quick laps, at one point getting himself six tenths ahead of anyone else.
Nobody could beat his quickest time before the checkered flag. Nigel Melker ended the morning in second position for Mucke, nearly two tenths off Bottas. Andrea Caldarelli was third for Tech 1, ahead of Nico Muller of Jenzer and Lewis Williamson of Arden.
The teams concentrated on race simulations in the afternoon session, with nobody challenging the kind of lap times seen during the morning. Pedro Nunes held top spot for much of the session, only knocked into second when Alexander Sims went quickest for Status with half an hour remaining.
As drivers fitted new tyres at the end of the session, Bottas moved to the top spot, where he remained until the checkered flag. Williamson was second, ahead of Rio Haryanto for Manor, ART's James Calado and Tuesday's pacesetter Antonio Felix Da Costa.
