Batch of 10 cars on the rest did not provide between the qualifications and career, so his pace in qualifying for a certain amount of fuel to perform, which in turn defines the space when the first cavity.
So when the weight of cars have been published, it is possible that a man who was really a de facto faster.
And this time Barrichello, Brazil, even as the case may be implied in his comments after the qualifications.
Given fuel costs, adjusted net BBC Sport fuel is as follows:
1 lap 19 Rubens Barrichello
2 Heikki Kovalainen 0.216secs (round 16)
3 Lewis Hamilton 0249 (round 15)
4 Jenson Button 0291 (round 18)
5 Sebastian Vettel 0507 (round 16)
6 Nico Rosberg 0540 (round 20)
7 Mark Webber 0610 (round 20)
8 Kimi Räikkönen 0614 (round 18)
9 Fernando Alonso 0871 (round 17)
10 Robert Kubica 1,114 (round 17)
Barrichello is around 9.5 kg more fuel than Hamilton, which means it will probably four rounds before the race. Is likely to create an exciting Grand Prix.
Hamilton and Kovalainen, is almost certain that the use of their systems to offer to ensure that workers will be held earlier. However, the assumption of Italy can live with them - and there is no reason why it should not be capable of faster cars - has the opportunity to add the first stop in the pits.
Thus, despite the strange, Barrichello is in fact a strong position for his first win of the season - and notes that at least in these conditions of heat, Brawn has returned to form here in Valencia.
Kovalainen second in a network of custom fuel confirms the good results that occurred on Saturday afternoon, even small errors, which is the fourth cycle, which arrives May Pole in the final session.
But this is not the first time the Finn was faster than Hamilton in qualifying the fuel must adjust the time of the year. Your problem - how to make their position vulnerable groups in 2010 - that is having trouble converting the strong momentum in the performance race.
The fifth position on the grid for the button, and the fourth fuel corrected times, do not score well on his way to world leaders in the league, which is far from the pace of Barrichello.
Moreover, just four percent less than its closest championship rival, Red Bull Mark Webber, who had 18.5 points below the button.
Teammate of Webber, Sebastian Vettel, who was 1.5 points behind in third place in the league before the button on the web.
However, the button is just a place behind, and English has two advantages - the car is faster, and is very clean and the cause of the network may be enough to get ahead of the curve first Vettel.
The race, as if between McLaren and Brawn. Inaugural event last year was an impressive boredom.
Year, however, seems to provide enough excitement to fans awake in suffocating heat.
