Oh dear, a problem for Haas as Romain Grosjean is off the circuit at Turn 4. 

That will signal an ever so slightly early lunch.

The red flag is waved just before lunch. 

Kimi Raikkonen, Nico Rosberg, Max Verstappen, Daniil Kvyat, Felipe Massa and Romain Grosjean were all out on the circuit.

Because of the sheer amount of mileage the Mercedes has been able to do the team didn't want to tire the drivers out.

What would you do if you were in charge of Formula 1?

F1 journalist Dan Knutson in Barcelona: "Max Verstappen did a lap on the ultra softs. He set his personal best times in sectors 1 and 3, but not in sector 2. So, once again the drivers are having problems getting the super and ultra soft tyres to work for a whole lap."

It feels like times have been changing every time I write an update, but things are pretty quiet on the circuit now. 

Felipe Massa and Romain Grosjean are out there, while a flash of silver leaving the pits means Nico Rosberg is out for the final 20 minutes before lunch.

These things are getting a mention again...

We'll get a full run down of what compound the fastest times were set on, but Kimi Raikkonen's was on the ultra soft, while Nico Hulkenberg has just improved slightly to 1:23.251 on his ultra soft run, almost half a second down on the Ferrari.

Max Verstappen's time came on the soft tyre, with Nico Rosberg doing his on mediums.

1. Kimi Raikkonen 1:22.765 34 laps

2. Nico Hulkenberg 1:23.352 45 laps

3. Max Verstappen 1:23.650 45 laps

4. Nico Rosberg 1:24.126 68 laps

5. Felipe Nasr 1:24.760 34 laps

6. Fernando Alonso 1:24.870 50 laps

7. Daniil Kvyat 1:25.141 44 laps

8. Felipe Massa 1:25.962 30 laps

9. Jolyon Palmer 1:27.182 26 laps

10. Romain Grosjean 1:28.442 35 laps

11. Pascal Wehrlein 1:28.476 18 laps

Kimi Raikkonen has swapped from the super soft to the ultra soft compound and he goes even quicker with 1:22.765. 

Halo removed, Raikkonen has turned into a devil on track.

F1 journalist Dan Knutson in Barcelona: "Team Haas is now on an “hourly plan” after the car completed just one lap yesterday because of turbo problems.

"'We will just have to try and get a race simulation in and get as many laps as possible to learn what the car is doing and what other problems we have,' Team Principal Guenther Steiner said last night. 'The main aim is to get as many laps in as possible.

"'Depending on how tomorrow goes is how we go on Friday. It’s not a weekly plan, it’s an hourly plan, so we could change tack depending on how we go tomorrow. Maybe we can be confident we have analysed the problem and made the fix, but you never know what is coming next. I think we will be good to go again tomorrow.'

"It’s now 'tomorrow,' and Romain Grosjean completed just over 20 laps in the first three hours.

Ferrari are finally doing some quick laps on the soft tyre and the result is very interesting. 

Kimi Raikkonen’s 1:23.009, which he has just set, is a smudge faster than the fastest lap of the week so far - Nico Rosberg’s 1:23.022 from Tuesday and that makes it the fastest soft-tyre lap of the winter. 

Problem is, Mercedes have not yet done any qualifying-type laps this morning so there is no direct comparison. And the track is definitely colder and windier on Thursday than it was on Tuesday.

Kimi Raikkonen is on one today. He improves on his timesheet-leading time by clocking 1:23.009 on soft tyres.

In Kimi speak, I'd imagine that lap was 'OK'...
