Will Stevens topped the final full day of pre-season Formula Renault 3.5 testing at Barcelona on Wednesday
The British driver led title favourites Kevin Magnussen and Antonio Felix da Costa in the afternoon running, as conditions improved after a morning of changeable weather.
Marco Sorensen and Nico Muller made sure the top five was filled with drivers returning for a second FR3.5 season, while Formula Renault Eurocup champion Stoffel Vandoorne was the top rookie in sixth.
McLaren junior driver Vandoorne had led the way in the morning, as he and Fortec team-mate Oliver Webb shone when the track was ready for slick tyres.
Neither Fortec driver got involved in the rush towards the end of the day on new tyres, meaning that they were the only drivers in the top 20 to set their fastest times in the morning.
"I wasn't really looking for performance," said Vandoorne of his afternoon programme.
"I didn't go out with much downforce this afternoon because I wanted to get familiar with the set-up for Monza [for the season-opener]."
The teams will get another half day of testing on the eve of the first round, as the first of two sessions at the first two events to make up for the day of running that was lost at Aragon due to snow.

The 2015 Formula Renault 3.5 season will be notable for being the last with the French company's backing but also produced a worthy champion in Oliver Rowland. PETER MILLS evaluates this year's crop of drivers
Last year's field was extraordinary and hard to match, but the Formula Renault 3.5 grid will still have plenty of talent this season. Glenn Freeman runs through the field ahead of this weekend's season opener
Landing the Fortec seat that took rising star Robin Frijns to the 2012 FR3.5 title was already a good sign for Stoffel Vandoorne. Then McLaren took him under its wing. Peter Mills tells Vandoorne's story so far
