Britain: Fuel adjusted qualifying times
The FIA now publishes the weights of each car after qualifying on Saturday. Those cars that make it through to the final qualifying session must use the fuel they qualified with while the rest of the field may refuel before the race.
Below is a graph showing the actual top ten qualifying times as well as those times adjusted for the weight of fuel each car is carrying. The graph assumes a standard lap time cost of 0.3 seconds per 10kg of fuel.
Nobody looks particularly out of place, although Kazuki Nakajima’s time was only possible because he was fuelled lighter than anyone else on the grid.
What it does show is how fast Sebastian Vettel really was. His team mate Mark Webber was fuelled lighter than him but could only manage 3rd. Vettel looks a lot faster than anyone else on the grid.
