They have only gone a couple of tenths quicker than last year whereas most of the other teams have gone a second or a second and a half quicker than their 2016 times.
Jolyon Palmer didn't improve so he is out. Also, a terrible session for Williams. Both cars out...

I've just been down to Haas to ask if they could fix Kevin Magnussen's suspension and has it done any damage to the gear box?
The unfortunate reply I got was, "he's done"...
Esteban Ocon improves and nudges Jolyon Palmer into trouble. The Briton is on a flying lap now, though. Can he get into Q2?

Image source, EPA"There is already some vibration on these tyres..." says Hamilton in a gloomy sounding voice.
It doesn't stop him from going quickest of all, though, as he does a 1:05.238 to move three tenths clear of Sebastian Vettel.
Hamilton is on ultra-softs, however.

That is a good run from Sebastian Vettel but he still has a little way to go before he reaches his peak. Although that time will send him through to Q2.
Image source, ReutersSebastian Vettel goes top of the pile with a 1:05:585. That's eight tenths quicker than Daniel Ricciardo, who is on the faster tyre. Impressive.
A moment for Romain Grosjean as he goes for a trip into the gravel.
Surprising lack of moaning over the airwaves from the Frenchman so far today.
Haas had a very good final practice session with both cars inside the top 10 and Kevin Magnussen has just gone quickest courtesy of a 1:06.143 on ultra-softs.
Image source, EPAThe Saubers are the first to post times as Marcus Ericsson sets the early pace with a 1:07.764. Pascal Wehrlein is around three tenths of a second slower. They are on the ultra-softs but Sebastian Vettel has just emerged with super-softs on his Ferrari.

The clouds can develop here very quickly - you can get rain on one part of the circuit very quickly and the teams will not just be looking at their radar forecasts, they will also be physically looking outside at the sky over the back end of the circuit.
This was the scene on Lewis Hamilton's side of the garage a few minutes ago.
Right now he is putting on his race helmet and stepping into his car. Looks like he is good to go.
