James Calado was the fastest man of the second day of testing in Barcelona as the rain continued to fall.
The ART driver, who was quickest when the track was at its wettest on day one, once again set the pace in the morning session and his time of 1m50.218s was unbeaten for the rest of the day.
Calado was second to Johnny Cecotto in the afternoon session, but the Venezuelan was over two seconds off the Brit’s earlier time.
In fact Calado was one of only two men to dip into the 1m50 bracket in the morning running, but even Carlin‘s Felipe Nasr was still almost seven tenths adrift of the 23 year old’s pace.
In a heavily disrupted start to the day, the treacherous conditions saw the morning session end prematurely after first Daniel Abt and then Cecotto fell foul of the wet track at turn four.
The weather failed to improve in the afternoon, with red flags once again appearing for the stricken Riccardo Agostini, Julian Leal and Rene Binder who all suffered minor offs.
And although Cecotto recovered from his earlier off to secure top spot in the afternoon, it was not enough to depose the ART as the fastest man overall.
