Just Nasr out on track at the moment in the Sauber. Soft tyres bolted on.
@ian: Yes, all the other eight cars have been out for at least 10 laps.
@RonLongwood: Engine upgrades have a fairly long lead time, so it's not like they work on something and it's ready by the end of the week. Right now it seems Honda's main focus should be reliability, but there is nothing stopping them working on performance parts on the assumption they will be able to add them this year - or even for next year.
@drynog: Yes. They had the car at the final test but it just stayed in the garage. I think it was just 11 laps by the time they arrived in Australia where they failed to qualify. Their first season wasn't much better, Karun Chandhok's car wasn't ready until qualifying day if I remember correctly.
@Damon: Don't read too much into that time - just like Vettel's, it's not a true representation of the pace of the car. Hopefully we will see that later today
@Canuck: Track temperature is up to 24C today. That's about 10C up on yesterday afternoon.
@Senthil: That's what we are expecting. Ferrari was pretty happy with Raikkonen's day yesterday, he set his quick time just before lunch, so we'll keep an eye on the Ferrari garage to see if Vettel goes out on super-softs
@ManuPaul: Not right now. No laps from McLaren so far today
They did say they hoped to be out in the morning session, but just 35 minutes left now before lunch.
@Canuck: So far they have only said they are running system checks, but 3.5 hours is a long time for that without the car turning a wheel.
Rosberg is the only driver on track. Medium tyres fitted to his Mercedes - he said on Friday that he wasn't happy with the oversteer he was getting while using the mediums, so I imagine he is trying to find a solution.
And as I type Rosberg returns to the pits for more fettling.
@ian: Here are the relevant regulations:
5.3.1 Cylinder bore diameter must be 80mm (+/- 0.1mm).
5.3.2 The crankshaft centre line must lie on the car centre line and 90mm (+/-0.5mm) above the reference plane. The power unit may only transmit torque to the gearbox by means of a single output shaft that must be co-axial with the crankshaft. The output shaft must rotate clockwise when viewed from the front of the car.
5.3.3 Valve stem diameter must not be less than 4.95mm.
The McLaren has just been fired up. Hopefully we'll see Button on track before lunch.
Nasr is out there on super-softs and has improved to 1:24.023. Ferrari has bolted some mediums on Vettel's car and sent him out too.
Vettel improves to a 1:25.552 to go fourth fastest using the medium tyres.
@yash: Perez has improved and is now on the super-soft tyres. He just set a 1:25.113, but that's still over two seconds off Bottas' pace in the Williams on the same tyres.
@noski: No, our last update was two hours ago on the ERS problem. That could take a while to fix, so I wouldn't be surprised if we don't see the camouflaged RB11 again before lunch. Incidentally, it's the last day for the black and white livery - I for one am going to miss it
Nasr, Vettel, Perez, Rosberg and Verstappen are all on track with 20 minutes to go before lunch.
@nikhilesh: Judging by the lap time it wasn't a quali sim. If it was then the Force India is at least two seconds off the Williams with the same power unit and tyres.
@9021: Nope, he's been writing up the latest words of wisdom from Ferrari boss Maurizio Arrivabene. He might go hunting for sandbags later.
@nikhilesh: We've been promised something even better than the camouflage by Christian Horner, but I doubt we'll see a dramatic departure from the familiar blue, purple, red and yellow.
