I've not had chance to tally them all but for a quick comparison Mercedes completed 378 laps in the first test in Barcelona (the second of three tests). This year, they are on 660 for the four days so far.

That's 1908 miles. They have basically driven from London to Istanbul.

Kimi Raikkonen has risen from his chair and is back out on the circuit.

The Finn set the fastest time ages ago, but has spent the last four hours in the garage being shown slides from his chief mechanic's winter holiday.*

*might not be true.

Is K-Mag the new Kimi? Does what he wants, when he wants.

Might as well try and squeeze in the last few look-a-likes. 

Not quite a celebrity but I'll allow it because Graham Hill most definitely had the look of a dashing pilot.

The Haas has been removed from the circuit and the track is open again.

Alfonso is straight out. Alfonso Celis of Force India that is. Time is fast running out for Fernando Alonso to add to his three laps...

Williams haven't sent Felipe Massa out for much track time this afternoon. He's added just six laps to his morning total.

Kimi Raikkonen 1:23.477 58 laps

Daniil Kvyat 1:24.293 85 laps    

Kevin Magnussen 1:25.263 142 laps

Max Verstappen 1:25.393 110 laps

Alfonso Celis 1:25.874 59 laps    

Felipe Nasr 1:25.874 96 laps

Nico Rosberg 1:26.187 62 laps

Lewis Hamilton 1:26.295 99 laps

Esteban Gutierrez 1:27.802 89 laps   

Rio Haryanto 1:28.266 51 laps 

Felipe Massa 1:28.684 34 laps 

Fernando Alonso No time 3 laps

The recovery vehicle has made its way to the stricken Haas. While we wait for it be moved and the track to open again let's have a look at the latest times and laps.

Someone has come to a stop on the circuit, and it is Esteban Gutierrez in the Haas. It's at turn four.

We are closing in on the final hour of testing. 

Still no sign of Kimi Raikkonen, who may well still be receiving instructions, while the McLaren remains firmly in the garage.

On the track, Nico Rosberg has just improved a smidgen, clocking 1:26.187.

Daniil Kvyat is out on the ultra softs. Has he got his eye on nicking top spot off Kimi Raikkonen as the Finn continues to be lectured?

Kvyat has a go and improves with a 1:24.329, but it is not enough to dislodge Kimi, who set 1:23.477 in the morning.

They should leave all the cars sitting empty on the start-finish straight and then let the drivers leg it from the paddock and dive into whichever car they can. Sorted.

It is going to be interesting to see how the battle in midfield shapes up. Force India have looked impressive so far, quietly going out their business putting in good times and amassing plenty of mileage. It could also be quite close between Manor and Sauber. Where do we see Haas slotting into the grid?

Meanwhile, on the track it is Kevin Magnussen, Daniil Kvyat and Max Verstappen who are putting in the laps.

F1 journalist Dan Knutson: "Lewis Hamilton and his dog are getting ready to leave, and his luggage is being loaded in the Mercedes that will take them to the airport. That has drawn a crowd in the paddock as the fans and media hoped to get a glimpse of them."

Wondering what Lewis Hamilton is up to? Is he watching Nico Rosberg? Racing up and down the paddock on his hoverboard? 

No, it looks like he is off... 

Right, here's what we've got to watch out for in the final two hours:

• Nico Rosberg has completed 44 laps. He needs 56 more to surpass Lewis Hamilton's total.
• McLaren are still hopeful of getting Fernando Alonso out. He's managed just three laps so far today.
