Pastor Maldonado ended the final day of the post-Spanish Grand Prix test fastest for Lotus.
Maldonado, who suffered a miserable race weekend in Spain, had been fastest in the morning, losing the top spot to Nico Rosberg in the early afternoon, before a late flurry on the super soft tyres on his final run returned the Venezuelan to the top of the time sheets with a best lap of 1:24.871.
Rosberg, who was trialling a new style ‘megaphone’ exhaust in the morning on his Mercedes, ended the day second overall, nine tenths shy of Maldonado’s best time, the German having switched to a more conventional style exhaust for the afternoon.
In what was a busy day for all the drivers, the top two both completed 102 laps of the Circuit de Catalunya respectively.
Kimi Raikkonen ended the final day of the test in third for Ferrari, adding 93 laps to the mere 20 he completed on Tuesday.
Esteban Gutierrez was fourth in the Sauber, one spot ahead of Susie Wolff, who completed 55 laps on her first day at the wheel of the 2014 Williams, despite a spin in the morning.
Jules Bianchi missed most of the days running, but appeared late in the session to go sixth fastest for Marussia.
Sebastian Vettel ended the second in-season test with seventh fastest overall, the German completing 72 laps in the RB10, despite a two hour delay in the morning.
Daniel Juncadella and Stoffel Vandoorne both spent Wednesday completing tyre test work for Pirelli, and ended the day eighth and ninth for Force India and McLaren respectively.
The Belgian completed 135 laps over the course of the day, on what was his first taste of current Formula One machinery at the wheel of the McLaren.
Daniil Kvayt propped up the order in 10th, completing just 21 laps as a result of two stoppages out on track.
Caterham did not take part in the final day of running owing to a crash for Kamui Koabayashi late on Tuesday, which damaged the chassis.
Robin Frijns had been scheduled to take the wheel of the CT05.
