Thanks and goodnight

OK, that's us done for the evening. 

It's always dangerous to read too much into practice times but you have to say Nico Rosberg looks in decent shape heading into the weekend. Add into the mix a rapid Red Bull, and Lewis Hamilton looks like he's in for quite a battle over the next couple of days as he bids to boost his title chances. 

Click here to read Andrew Benson's FP2 report. M'coll Gary Rose will be with you for third free practice at 16:00 BST on Saturday, followed by qualifying at 19:00. 

Bye for now.

Spin for Sainz

We saw a replay of a spinning Carlos Sainz as that session ended. 

The Toro Rosso driver sailed a long way off circuit, wheels-locked, and ended with huge flat spots on his medium tyres. 

Back to the pits for the Spaniard.

Chequered flag

FP2 is over.

No changes over those slower final runs so here's the final standings: 1 Rosberg 2 Ricciardo 3 Hamilton 4 Vettel 5 Verstappen 6 Hulkenberg 7 Perez 8 Button 9 Alonso 10 Raikkonen    

Someone tape up that Haas!

More debris flying off through those fast sweeping esses, and again it's the Haas doing the shedding.

It's Esteban Gutierrez's car losing weight on this occasion.  

Will the FIA take a dim view of this?

Ricciardo 'quicker' than Mercedes drivers

Our very own Andrew Benson has been studying the long-run lap times and he says Daniel Ricciardo's pace in the Red Bull is a couple of tenths up on the Mercedes drivers.

Tyre trouble creeping in

A few drivers are moaning about their tyres. 

Lewis Hamilton has complained about a "vibration" on his set of medium tyres, while Verstappen says the softs on his Red Bull are "gone". Marcus Ericsson, meanwhile, says his tyres are "falling apart completely".

Palmer spins off

Yellow flags for the yellow car.

That's a second off today for the British driver in the Renault. 

He loses it in Turn 8, takes a trip backwards over the grass and then continues.

Little more than 20 minutes left on the clock and we have @HulkHulkenberg in P6 and @SChecoPerez in P7. Just 0.06 between them! #USGP

Top 10 - 20 minutes to go

The order is not changing during these long runs. Just a reminder of the top 10 as it stands.

Grosjean again shedding car parts

Our radio colleagues say that it was the Haas of Romain Grosjean liberally distributing car parts in the first sector a few minutes ago.

The same thing happened to the Haas in FP1. 

Interesting. Clearly there's something that doesn't want to adhere to that car through those fast esses. 

Green flag

We're running again.

On this day (2007): Raikkonen pips McLaren duo to title

Our third and final title decider for 21 October takes us to 2007. 

This was a weird one. Kimi Raikkonen was there or thereabouts for much of the year but fell 20 points back by just after mid-season, with the title seemingly destined for one of McLaren's drivers - Fernando Alonso and rookie Lewis Hamilton.  

Entering the final race in Brazil, Raikkonen was seven points behind Hamilton and needing everything to go in his favour. In the end, Hamilton hit gearbox trouble and finished seventh, Alonso finished in third, and Raikkonen came through for a win after Ferrari team-mate Felipe Massa moved over. 

Final points total: Raikkonen 110; Hamilton 109; Alonso 109.

Red flag

The session has been halted. Looks like it's debris-related. 

Not sure which car is shedding its component parts this time.

Anyway, a sporting marshal has just run out and picked up the offending item.

And now to the long runs...

The teams have gone the other way now and we're onto the long, race-sim runs. The Mercedes duo are on used super-softs.

Promising for McLaren

The McLarens have gone out on quali-sim runs and they've both popped into the top 10, right on the tails of the two Force Indias. 

Jenson Button is up to P8 with a time a tenth slower than Sergio Perez. Team-mate Fernando Alonso is in P9, 0.088s further back.

McLaren are hoping for a lot better this weekend after their miserable showing in Japan a fortnight ago.

Just over 30mins into #FP2 and here's how things look: @nico_rosberg P1, 1:37:358, 7 laps @LewisHamilton P3, 1:37:649, 9 laps #USGP #F1

Advantage Rosberg?

So the Mercedes drivers have had their first nibble at the quali simulation laps and it's Rosberg with the edge over Hamilton. 

Title leader Rosberg improves his fastest time to 1:37.358, while Hamilton can only slot into third place with a time 0.291 slower.

The man in the middle? Daniel Riccardo's Red Bull - just 0.194 off Rosberg. That Red Bull is looking very strong - particularly in the first sector.

Qualifying sim runs under way

A few super-soft tyres going on now. Teams are doing their qualifying simulation runs so the times should start to come down.

Rosberg is among them.

Raikkonen runs wide

A moment of drama from Kimi Raikkonen as his Ferrari snaps away from him on the way into Turn 19. 

He saves the spin but runs very wide. 

Moments later he's on the radio - in that famous monotone of his - saying: "I don't know why but the car is very bad at the rear."   

Red Bulls get racy

Red Bull went through the first session using just the medium tyre but both drivers have had a run on the soft in this session now. 

So far Daniel Ricciardo has the edge, but only just - he squeezes into third place by just 0.012s from team-mate Max Verstappen.

On this day (1990): Senna takes off Prost to win title

It's 26 years since this particularly large slice of F1 drama took place at the start of the Japanese Grand Prix. 

If you're reading this page you probably don't need me to remind you of the salient points of this incident. Let's just say Ayrton Senna warned he would not yield into the first corner after complaining that the pole position berth was on the wrong side of the track, and he was as good as his word. 

With both Senna and title rival (and bitter rival) Alain Prost out, a second title was in the bag for the Brazilian. A third would follow in 1991.

Ocon spins off

Yellow flags in sector three and it's Esteban Ocon facing the wrong way. 

A replay shows he lost it at high speed into Turn 18 and took a trip through the gravel. A rather jaunty spin-turn later and he's back on the track. 

Mercedes on top

No surprise to be writing this. Mercedes are now at the head of the pack. 

Rosberg - on the soft tyre - is quickest on a 1:38.082. Hamilton - on the medium tyre - is three tenths down. 

Verstappen is up to third place, one tenth behind Hamilton after his first soft-tyre run of the day.

Debris again an issue

We had a problem with debris on track in FP1 and it's happening again in this session. 

The drivers have been warned to be aware of debris in the esses in the first sector.

Ferrari lead the way in these early minutes, Sebastian Vettel first from Kimi Raikkonen by 0.038s. Then it's Kvyat's Toro Rosso and the Force India of Perez. 

The Mercedes boys are yet to set times in this session.

Mercedes team radio

Lewis Hamilton: "There's a vibration in these tyres - front tyres."

Ouch! That's gotta hurt

Poor Jordan King. 

He went out in FP1 and drove the wheels off the Manor, finishing two seconds ahead of team-mate Esteban Ocon.

Chest puffed out with pride, he was then listening in as BBC reporter Tom Clarkson asked Red Bull team boss Christian Horner - tongue-in-cheek - whether there would be a seat for King at Toro Rosso next season. 

"Who?" came Horner's unpromising reply.

Jordan King?

"Ah. He's not on our radar at the moment. He's obviously having a good run in the Manor but he's not on our radar."

Go! Go! Go!

FP2 begins.

Get Involved - just how good is Alonso?

adarsh gm Alonso 3rd best driver in the history of F1 behind Senna and Prost.With a bit of luck he would have been a 5 time world champion.

Ian Difficult to rank but up there with Fangio, Senna, Shumacher, Prost, Stewart. Able to get most out of car in any situation

Calixto Érico Top 15. Rare mix of talent/speed/racecraft, but missed open goals & should have done more. Lots of mistakes in 07, 08, 10.

We've been asking for your views on Fernando Alonso after his interview with Andrew Benson this week.
