Fuel consumption here is 2.9kg per lap and the fuel effect is 0.35 secs per 10 kg. We can see therefore that Trulli decimated his team mate. A very strong run by the Italian. But he's still lighter than Vettel's Red Bull, Hamilton's McLaren and Button's Brawn. Vettel could have the strategy in place to do the double this weekend. Rosberg is heavy, so maybe he can do something from ninth, as is Kimi Raikkonen in the improving Ferrari. He had no new tyres left for Q3 - if he had, he would have been quicker.

Predictions for today? I've always said Toyota will be up there. They're light, particularly Glock, but Jarno has a shot at a win today and should expect a podium at the very least. Vettel is looking really good and could well win. Hamilton is the fastest we've seen him this season and his strategy should deliver a podium if the team get it right this afternoon. The Brawns of Button and Barrichello perform better in the race than qualifying and will also be right up there, but I understand Brawn are experiencing cooling problems which could affect them here.

So, if I were to stick my neck out, I would predict the following podium:

1) Sebastian Vettel

2) Jarno Trulli

3) Lewis Hamilton
