Ferrari’s Kimi Raikkonen ended the penultimate day of the second test in Barcelona on top of the time sheets.

Raikkonen set his fastest time of 1:22.765 in the morning session using Pirelli’s Ultra Soft Compound tyre. But before that, Ferrari trailed the “Halo” head protection that the FIA hope to get on the cars by 2017.

Raikkonen’s reaction to the new device was classic Kimi. “A little bit limited in the front, but I don’t think it’s the final version. Surprisingly little difference.”

There were mixed reactions from the drivers and from fans across social media. Some are all for it and were very complimentary while others mocked the looks and questioned the practicality of it.

After turbo troubles  on Wednesday the Haas F1 team aimed for a complete race simulation on Thursday. Things did not go according to plan for the Kannapolis based team. Romain Grosjean Brought out the red flag three times on Thursday. The first time he went off at Turn 4 in the morning session and again at Turn 1 in the afternoon. He managed to avoid the barriers and the team was able to get him back out on track. With 5mins left in the session, Grosjean once again brought out the red flags stopping out on track. Despite the troubles Grosjean racked up 78 laps.
