Grid and weights

Using a car minimum weight of 605kg, and fuel consumption of 2.88kg/lap (thanks to Williams) and allowing some excess weight for driver weight loss (heat leads to water loss) and fuel for the formation lap and the drive to the grid, I estimate that the cars will stop as follows (pole on left):

Front row: Trulli (12) Glock (10/11)
2nd row: Vettel (16) Button (14)
3rd row: Hamilton (14) Barrichello (12/13)
4th row: Alonso (13) Massa (18)
5th row: Rosberg (20) Raikkonen (20)
6th row: Kovaleinen (13) Nakajima (23/24)
7th row: Kubica (30) Heidfeld (29)
8th row: Piquet (22/23) Buemi (23)
9th row: Fisichella (13/14) Webber (15)
10th row: Sutil (23) Bourdais (19)

KERS cars in brackets, drivers I expect to start on softs in italics. It is a 57 lap race, and I'm working on the assumption that teams will choose a 2 stop strategy (except perhaps BMW). I also expect Massa and Bourdais to take long middle stints, to provide a short super-soft period.

Having said all that, the super-softs are designed to work in the conditions expected tomorrow, so shouldn't degrade as they did in Melbourne.
