Force India’s Nico Hulkenberg set the pace during the third day of pre-season testing in Barcelona, being the only driver to try the super-soft compound.
After watching the opening two days of the test from the sidelines, Hulkenberg got his first taste of VJM09, as he completed 99 laps of the Spanish circuit.
His quickest time, 1:23.110, was nearly 2.8 seconds quicker than the Haas of Romain Grosjean, who moved up a few positions after a late run on soft compound.
In all, it was a good day for Haas, with the Frenchman lodging 82 laps and gathering plenty of data for the engineers to analyse.
Third on the board was Kimi Raikkonen, the Finn having to spend hours in garage following a fuel pump failure.
Behind, Renault and Kevin Magnussen enjoyed a productive day in Barcelona, after two troubled sessions, with the Dutch driver completing well over 100 laps.
However, Renault still has to get on top of some of their reliability issues, as vindicated when Magnussen stopped on track during the final hour.
Mercedes drivers Nico Rosberg and Lewis Hamilton split duties today to prevent extra load on a single driver, given the number of laps they have been completing every day.
Rosberg finished fifth quickest with 74 laps, while Hamilton finished two tenths down, but more significantly, completed 13 more laps in the W07 Hybrid.
Carlos Sainz was sandwiched between the two Mercedes drivers in sixth after a long, and mostly trouble free day where he lodged 161 laps - more than any other driver today.
Daniil Kvyat and Felipe Massa were ninth and 10th respectively, while Jenson Button finished 11th in the timesheets. The McLaren driver was reduced to just 51 laps with a hydraulics leak.
And finally, Indonesian debutant Rio Haryanto brought the rear of the table, some six seconds off the pace of Hulkenberg’s super-soft run.
