Valtteri Bottas drove the fastest time so far in the pre-season tests in Barcelona after he clocked 1:19.310 in the morning part of the session, four tenths faster than the previous best time he set last week.
Finn managed to improve his best time from last week (1:19.705 on the ultrasoft) on harder supersoft tyres while Massa clocked the fastest time so far on the ultrasoft, three tenths faster than his yesterday time on the supersoft.
Raikkonen was third, fastest of the drivers who had set their best time on the soft tyres, but the Finn has clocked only 53 laps all day, 115 less than his team mate Sebastian Vettel managed yesterday.
Kimi crashed an hour and a half before the end of the day after he flew off in a fast third corner and damaged the front wing and left front suspension, and his incident caused one of three red flags. Finn didn’t go out by the end of the day because of the severity of damage to his car.
Max Verstappen was fourth fastest in the Red Bull, 26 thousandths behind Raikkonen, but with 102 rounds for new RB13 who broke the 100 laps mark for the first time in six days. Verstappen also drove the most laps of all drivers in the second day.
However, neither Red Bull had a perfect day because they had to change Renault’s power unit and so lost four hours while Verstappen caused the second red flag 20 minutes before the end when his RB13 stopped in the Turn 12 during the race simulation.
Lance Stroll drove the new FW40 for the first time this week after Massa was driving in the morning and set the fifth fastest time on the supersoft tires with a total of 59 laps.

Marcus Ericsson was 13th fastest with 46 laps, a Swede caused the third and final interruption after his Sauber stopped in the Turn 7, shortly after the break caused by Verstappen.
Jolyon Palmer in Renault drove the slowest time of the day, more than seven seconds slower than Bottas after he drove 29 laps in the afternoon part in his Renault R.S.17.
