F1 journalist Dan Knutson in Barcelona: Kimi Raikkonen completed the first 15 laps of his race distance on the super soft tyres, did 18 on the softs, and then switched to the medium compound Pirellis. It looked like he was doing the same thing Ferrari teammate Sebastian Vettel did in his race simulation yesterday and going the last half of the 66-lap run on the same set of tyres.

But that all ended after 12 laps on the mediums when he spun his Ferrari because of an apparent mechanical problem, stopped on track and brought out the red flags.

Kimi Raikkonen's Ferrari has been dealt with so we are back under way with just under 90 minutes remaining.

Paulinator Maximus: Ouch!! Ferrari discover a gearbox problem as the car is pushed on the last day of testing? Qually looks like it could be a problem.  

Kimi Raikkonen was approaching 100 laps for the day before coming to a stop. He got the fastest time in testing so far this morning but that's two incidents in the two days he's been involved in this week.

Time to hand the Karaoke mic over to Kimi?

A second spin this week for Kimi Raikkonen, it would appear.

Worry not, McLaren fans. It's the Ferrari that has brought out the red flag this time.

Red flag, the first of the afternoon...

We haven't seen Lewis Hamilton for a while and it's interesting to see him propping up the lap count at the moment. 

1) Lance Stroll - 99 laps

2) Kimi Raikkonen - 91 laps

3) Sergio Perez - 90 laps

4) Carlos Sainz - 86 laps

5) Romain Grosjean; Marcus Ericsson - 59 laps

6) Valtteri Bottas - 53 laps

7) Nico Hulkenberg - 45 laps

8) Max Verstappen - 33 laps

9) Fernando Alonso - 28 laps

10) Pascal Wehrlein - 27 laps

11) Jolyon Palmer - 20 laps

12) Lewis Hamilton - 19 laps 

McLaren are rapidly closing in on surpassing Red Bull's total laps for the day. Max Verstappen is still on 33 for the day because he has not been out since this morning. The reason? "Max's afternoon running limited so far as we run some checks on the turbo," says Red Bull. "Team pushing to get the #RB13, external back on track."

Some hot lap action for Romain Grosjean on ultra-softs. He clocks a personal best for the day but it is not enough to move him up from P10.

McLaren confirm that they "carried out several fixes to the car" after encountering an electrical issue this morning.

They are cracking on with their original afternoon plan.

F1 journalist Dan Knutson in Barcelona: Kimi Raikkonen is doing a race distance in the Ferrari. He did his first 15 laps on the super-soft Pirellis and then made this pit stop to switch to the soft compound tyres.

Fernando Alonso posts an improvement on the time he set this morning as he does a 1:22.412 on super-softs. He stays P12, but is up to 25 laps for the day now.

Fernando Alonso is back out on the track. He's got two hours and plenty of work to do. 

Fingers crossed for a trouble-free afternoon.
