Chequered flag

And that's a wrap for day two.

Valtteri Bottas finishes the day fastest with the 1:23.261 he set on super softs earlier.

Swift work by Sauber as they get Marcus Ericsson back out for the final two minutes after his earlier spin and the subsequent separation of his wheel.

Last minute action in the garage - compliments for the whole crew! Marcus is on track again #ME9

Kevin Magnussen is definitely done for the day, because there is a water leak on the Renault.

Elsewhere, there's been no major shift in the times. Sergio Perez has improved marginally but not enough to improve his place in eighth.

It looks like day two of testing will end with Valtteri Bottas top of the timesheet.

F1 journalist Dan Knutson: "I stood nearby when Pascal Wehrlein made a practice start in the Manor at the end of pit lane earlier today. When he wound the engine up to full rpm it was LOUD. My ears were ringing for a while afterwards. Of course, people can’t get this close during an actual race start, and so the sound gets dissipated before you hear it."

Is there time for another run? There always is. Except when there is no time. But today there is! #VamosCheco

Here's the aftermath of that Sauber spin a little earlier. 

No more laps for Renault, meanwhile, they are done for the day and at the moment Nico Rosberg, Sebastian Vettel, Daniel Ricciardo and Carlos Sainz are on the circuit.

Valtteri Bottas is also back out and has soft tyres on as Sergio Perez improves, clocking 1:26.036. He remains eighth fastest.

Only Bottas and Kevin Magnussen have given the super softs a go today. Anyone else for the final 25 minutes?

Race simulation done, Nico Rosberg is heading back out for the closing stages.

Sebastian Vettel is also out on the track.

We're really into this #IfAnythingCanStopMercedes thing and can see it becoming an obsession, so we're only going to do one more. Ready?

Is that a Sauber?

Go! Go! Go!

The Sauber and its missing wheel have been recovered by the flatbed truck and taken back to the pits, so the track is open once again.

Forty minutes remaining.

We've done well to get to one hour before the end of testing to have our first red flag of the day!

It is for the Sauber of Marcus Ericsson. He's in the gravel just after Turn 4 and facing the wrong direction.

A good day for McLaren, with Jenson Button passing a century of laps.

Maybe the predictions many of you gave earlier for the season are not too optimistic after all...

Is this the magic roundabout in Swindon? Proud to say it never caused me bother when I lived there. 

I guess that makes me better than Lewis Hamilton.

Just over an hour to go, and JB's getting down to business @Circuitcat_eng.

Jenson Button is also on a race simulation.

Race sims are the order of day for a number of teams today. We know Nico Rosberg and Daniil Ricciardo are doing them, with Rosberg coming to the end of his.

Carlos Sainz and Kevin Magnussen are also on race runs.

@bbcf1 Any chance of getting the tyres that drivers have set fastest laps on when updating the live feed? #bbcf1

Here's the tyres the fastest times were set on at lunch. 

Since then Valtteri Bottas has gone fastest on the supersoft while Nico Rosberg's time of 1:28.298 was on mediums.

Speaking of Haas, their running is done for the day. 

Esteban Gutierrez had managed just one install lap before the team spotted an anomaly after changing the turbo charger and he hasn't been out since.

Meanwhile, Daniel Ricciardo's race sim continues, he has just taken on a set of hard tyres. 

Problems? What problems?

Both Kimi Raikkonen and Ferrari customer team Haas have had reliability issues in testing, prompting speculation there may be problems with its engine.

Team principal Maurizio Arrivabene and there's been no issues for Sebastian Vettel when he has been in the car. He has had a trouble-free day so far and is on 107 laps and counting.

What are your thoughts on this? Let us know via#bbcf1

#F1 AT MOMENT it appears Q1+Q2 will be new elimination style from OZ GP onwards - Q3 top 8 cars will battle as before. Still to be approved.

General feeling from speaking to bosses in the paddock is there is still a lot up in the air but this plan might work to mix the race up #F1

We've got a new name at the top of the timesheet for today. Valtteri Bottas has reached for the super softs and popped out a solitary flying lap in which he clocked 1:23.261. 

That time is three tenths of a second quicker than Lewis Hamilton's, but the world champion had set his on the soft tyre.

And another whose programme for this afternoon involves a race simulation...

Nico Rosberg, into his third stint of his race simulation, posts a personal best for the day with 1:28.697. He's on to 43 laps now.

Like Nico Rosberg, Daniel Ricciardo also appears to be on a race simulation. A good chance to see how the two compare.
