Kimi Raikkonen took Ferrari to the top of the leaderboard on the second day of testing in Barcelona, although only just from Mercedes.
Following on from extremely good reliability from both teams on the opening day, it was Ferrari who would pip Mercedes this time by just 0.023 of a second. Lewis Hamilton set the fastest time for the team, with Valtteri Bottas being handed the car for the afternoon session and focusing on long runs.
Once again, those teams racking up the most number of laps were also faster, with Max Verstappen bringing the Red Bull to third and Kevin Magnussen in the Haas in fourth, with the team confirming there are no further updates to the car to come through testing.
Force India lost time in the morning, continuing from a cracked exhaust yesterday and a repair ate time into the morning. They still completed 86 laps with Esteban Ocon onboard and were fifth fastest. Arch rivals Williams lost the afternoon from a spin by rookie Lance Stroll, with the parts required for a fix not available and ended the day at the bottom of the pile.
Once again, it was McLaren-Honda who seemed to getting all the woe. Firstly Stoffel Vandoorne stopped at the entrance to the pit lane at the start of the morning session, the team trying to organise a fix for the oil pump, but an engine change lost them even more time completing just 40 laps. Someone else with an engine problem was Sauber, but rookie step-in Antonio Giovanazzi still managed to complete a good 67 laps for ninth place.
