Ham on 2013 tyres, both Bulls on 2012 tyres, by my reckoning. I missed the others though.

Yeh, it's very hard to tell the relative pace... The 2013 tyres were meant to be quicker... on the other hand the track rubbered in, and lewis did a lot of race pace running late in the session, rather than setting a new quick lap.
Interesting AMuS article (German/Google translation) on the new tyres.
Tenor: softer sidewall and stiffer tread, two tenths faster, more grip in the apex, easier getting to work, but degrade faster.

Could be anticipating that Button will qualify further down the grid anyway, so they are setting him up to overtake. His long run pace was similar to Hamilton's so he should be able to factor, and given two straights where there is an opportunity to overtake then being THAT much faster in a straight line than the entire rest of the grid could play into his hands.

He was 6 kmph faster than the next car, and 13 kmph faster than the Red Bulls who were pretty much slowest of all. Add another 10 kmph for a DRS assisted overtake and he's going to have quite the advantage in the race. This can work even in the wet if the mechanical grip of the car is good (it usually is).

Sam Michael said to AMuS both will have the high downforce setup tomorrow as they're expecting rain.

That will suit Red Bull fine.

Apparently some forecasts are saying a cold front is moving in and rain could hit earlier than predicted before. It could end up hitting quali instead, or hitting between race/quali.

Button also commented the choice of using the low df configuration in free practice for F1.com
F1.com wrote:Q: Jenson, many of your peers speak of the difficult tyre situation. What is your impression? Any issues today?
Jenson Button: No, not really. True it was unusually hot today - hotter than we’d expected and this is probably going to be difficult for the weekend - but for today, no. We’ve been running a different aero package in the afternoon - and that was quite interesting. When it is hot you have less downforce and then it always gets quite tricky. But it was a useful afternoon. (laughs)

Q: So with conditions expected to change your crew will work until late to give you a different car tomorrow?
JB: Definitely. The temperatures will be also very different tomorrow than to Sunday. The wing level that we’ve been trying, there is a very small chance that we will be racing that on Sunday, but it was a very useful information for next year.

Q: Can you give us a bit more information on the low-downforce running in today’s practice?
JB: It was to see how the wing works and to get information, really. It was the worst condition to run a low-downforce car, because with such high temperatures there is more sliding and you overheat the tyres. It sure was not perfect in terms of lap times, but it was useful data. Surprisingly on the long run it wasn’t that bad. It was only on the short runs, as you can’t use DRS where you’d like.

Q: But when it rains you very likely will not go for a low-downforce car?
JB: No, that is also true. And there is really a big chance of rain on Sunday.

Q: So if it is hot on Friday and Saturday but cooler and rainy on Sunday, how are you preparing? And how useful are these sessions to prepare for the race?
JB: Well, these sessions are just to see how the car is if it is dry. There is the chance that it is dry tomorrow for qualifying and maybe miracles happen and it is also dry on Sunday. But true, today’s conditions were not useful testing for wet tyres, so you have to get the most out of the situation by concentrating on data.

Q: You’ve been running a significantly different wing set-up to Lewis (Hamilton). Can you speak about why that is?
JB: We’ve been trying a wing that we’ve used earlier in the year and we’ve thought that probably it might work here - but the hot conditions trashed that hope.

Q: But isn’t it somewhat of a compromise at the season finale to be looking so much at next year, especially with the new development tyres?
JB: I think for every team it was a useful morning to have that tyre to play with and to start with. It is very different.

Q: When you’re going into qualifying tomorrow, will you do that on a wet set-up?
JB: No, because the cars today, if you set it up for dry if it is dry in qualifying, you need to be as close to the front. You still have the front wing to play with in the race.

Q: Would you welcome rain on Sunday?
JB: I’d prefer it dry, but of course it will be interesting in the wet. We haven’t driven in the wet for a long time and the last time we did our car wasn’t very quick around Silverstone time, so I hope that the upgrades that we did since then will help in the wet, as this was really a weak point for us. So let’s hope this weakness is a thing of the past.

I couldn't bring myself to work out long-run pace for once, for fear of not liking what I saw :lol:

Some driver reaction and insight:

Granted he's more lucky then the equal driver thing at McLaren, but isn't Alonso even more lucky with his teammate?

Interesting...Hamilton running either a rain map or he´s just hit the button by mistake.

You can see it at the end of FP2 doing long runs, rear light blinking.
Same as Hungary.

It looks like it will start to rain right at the end of Q3. So those who will go out first will pull the longest straw.

Perhaps he's doing it to help manage his rears. Put less torque & wheelspin through them to manage his overheating rears (which they were, apparently?). If he did his session-topping laptime with the rain map though... God help us all :lol: (except the Hamilton fans, naturally)

I'm very very disappointed with Simon Rennie. In FP2 Kimi radioed him to say, "Tell me if I'm overheating my tyres because I don't have any grip front or rear." He only replied "Understood, Kimi." He should've said "Yes, yes, yes, yes you don't have to remind me every second." :lol:

Most likely yes, i don´t know how many laps he did or when he turned it on but hopefully it was just to see how much it would help.
Hopefully they are on their game in Qualifying regardless of conditions so he can get that final win. Car looks mighty frankly.


Haha yea that would be awesome :)

If that were true the ramped exhaust teams could be slightly better off in their exhaust blowing.
the only team with ram exhasut is rbr
so are the rest of the team going to struggle?
lotus seems to be in between ramp and bulge
Eh? RBR got the design from Sauber!
i know and nobody is saying otherwise, as this is Brazil race thread and if you could just read my post properly you would know that i said, RBR is the only team in this race with ramp exhaust....Sauber is having mclaren style exhaust from canada i think? but i didnt know they changed to ramp exhaust now....that is my mistake
