More analysis:

http://www.f1wm.pl/php/wiad_gen.php?id=11343

It's in Polish. 3rd column is weight of the car in kgs, 4th column is weight of fuel in kgs, and the last column is the anticipated number of laps to pit.

Facinating information. Why would Kovy go into Q2 with some 70kg more fuel than needed? They only have to set their fuel for the race if they get into Q3, surley the point of Q1 and Q2 is to GET INTO Q3?. Most puzzling. Same can be said for both Force Indias and Piquet as well.

That'll be his race start weight, having been filled up after Q2 had finished.

Interesting to see Hamilton is going light. I think Rubens could've carried a few more kg's though.

James Allen on the car weights.

The fuel weights have been published by the FIA for the first time, under the new rules for this season.

There are some very interesting things here. For a start the Brawn cars are, as we expected, massively quick, given that Jenson Button’s car has 22 laps worth of fuel in it (59 kilos). Barrichello will go one lap longer, to 23. This is a long first stint for a two stop strategy.

Knowing this we can say that Jenson did a stunning job today in the final part of qualifying as the extra fuel he’s carrying will have given him less than a tenth of a second of lap time compared to Rubens and yet he is three tenths faster.

Rubens liked the car more on low fuel in the early part of qualifying, Jenson liked it more in heavy fuel mode. He will be on his own tomorrow in the race.

Sebastien Vettel, who qualified third, will go to lap 20, the same as Nico Rosberg. This means that the Red Bull is a couple of tenths faster than the Williams.

Meanwhile the Ferraris are in trouble, Massa has only 18 laps of fuel in his car and yet he was 8/10ths off Button, who has 3/10ths of a weight disadvantage. That puts the Ferrari a second slower in quali trim today. Raikkonen has a similar amount as his team mate and was a tenth slower.

Kubica’s lap looks less stellar when you realise that he is running light - he will be stopping on lap 17.

Button should control the race, reliability is his only competitor tomorrow. Barrichello has more than enough speed to stay ahead of Vettel and Rosberg who will be fighting for a podium. Massa moves forward to 6th on the grid after Glock’s exclusion and he has a shot at a podium from there to get his championship campaign off to a strong start. The Ferrari should prove a faster race car than qualifier here.

Do we need another thread for this? It's becoming a habit at the moment to start new threads on subjects that should be and are being discussed already in the main race weekend thread. Not having a go but can we not get out of this habit before it becomes a complete pain in the arse. wink

Disagree. This is new information to us lowly fans this year, and as such an important part of F1 racing these days, is realy worthy of a thread all of it's own.

No point, they want to do a 2 stop race which means throwing in three lots of about 20-25 laps worth of fuel. If you fuel heavier and still do a 2 stop you just handicap yourself for the first stint, the only reason you'd fuel heavier than the Brawns is if you were doing a one stopper.
