Spain 2009: Post-Qualifying Car Weights

Spain 2009: Post-Qualifying Car Weights

The top ten finishers have had their cars weighed and the rest of the pack have declared their fuel levels for tomorrow’s Spanish Grand Prix. From the weights of the cars we can work out how much fuel each car is carrying simply by deducting the minimum car-and-driver weight (605kg) from the total figure, and from this we can work out how many laps of gas they are each holding in their tanks. From this, we can allow one laps worth of fuel for grid forming and one more as a margin, and we can predict when the drivers will stop.

According to Williams (via F1Minute), fuel consumption around Circuit de Catalunya is about 2.27164 kilograms/lap.

From the table we can see that Jenson Button was relatively light on his final run, indicating that the other teams have indeed started to close the gap up to the Brackley squad. Sebastian Vettel and Felipe Massa did quite well with slightly heavier cars than those immediately around them, and both Red Bulls are on the same fuel level, although unless one driver falls particularly far behind the other in the opening laps, it is unlikely they will pit on the same lap.

Also worthy of a mention is Fernando Alonso, who is running light and will hope to make up some places at the start. Although it highlights how much his Renault is under-performing at the moment. Nico Rosberg is particularly heavy and will run a long first stint, as will many of those behind him. Lewis Hamilton is the heaviest driver while team mate Heikki Kovalainen is obviously looking to make up some places at the start as he is comparatively light.
