Kimi Raikkonen set the pace during the final day of the first pre-season test in Barcelona, lapping the Catalunya Circuit in 1:23.447 on a set of ultrasoft compound.
Daniil Kvyat, also on the ultrasoft tyre, was eight tenths slower in the Red Bull-Tag Heuer, with 96 laps on board.
Force India tester Alfonso Celis Jr, on his final pre-season outing for the team, was third quickest, setting a time of 1:24.640 on the slower supersoft tyre.
Although Renault didn’t enjoy a bulletproof day with Kevin Magnussen stopping on track at turn 3, he did complete 153 laps en route to the fourth fastest time of the session.
Behind, Max Verstappen was the quickest of the medium tyres runners, but some two seconds off the pace of Raikkonen’s ultrasoft benchmark. Toro Rosso is expected to bring a B-spec car during the final test next month.
Felipe Nasr, testing an upgraded 2015 Sauber, was sixth on board, with 121 laps to his name.
Like yesterday, Mercedes split duties between Lewis Hamilton and Nico Rosberg, with the duo completing 185 laps between them.
The team is clearly focusing on longer runs and trialled a new nose cone today, featuring an S-Duct that channels the air from underneath the car to the top.
Felipe Massa only racked up 54 laps in the Williams, finishing 9th in the timesheets, ahead of Esteban Gutierrez, who enjoyed another productive day in the Haas VF-01.
Indonesian debutant Rio Haryanto was 11th for Manor, and like Williams, could only lodge just over 50 laps.
And finally, Fernando Alonso propped up the timesheets in what was a disastrous day for McLaren. A coolant leak forced the Spaniard to spend almost the entire day on sidelines, as he only managed to complete three, untimed laps early on.
Team’s engine partner Honda will introduce a new version of their power unit during the next test in Barcelona.
