The guesswork continues. At least until the Saturday. Only qualified, you will know whom most punish the disarmament to the exhaust. The competition surprised, that suddenly as Black Red Bull technology Chief Adrian Newey looks.
The moment of truth begins in free practice at Silverstone. Then, all cars must give up the exhaust trick. And then no exhaust gases may be produced in the gas wegnehmen. This will lead any variation in the pressure. The question is: if it is how hard?
"That no one can give an answer, before we went not on the line so that", reply to the McLaren drivers Lewis Hamilton and Jenson button. Is not too much on the Friday practice Fernando Alonso: "We will wait the qualification, to have an accurate picture." Rubens Barrichello joked: "We had previously zero, and null now." "For us practically nothing will change."
The Simulator is only a little help. "You feel already, that something different is so previously, can but difficult to estimate how much", Sebastian Vettel is confirmed. Then the World Championship leader explains: "In the work of the Simulator you compare yourself with the last step." "If you suddenly zuruckgehst to zero, the judgement missing you, how big is the difference."
From Red Bull will not smart these days. The first reaction after the official ban was: this is all the same. In Valencia, team Advisor Helmut Marko conceded: "We are half a second losing." Of assuming even at Ferrari and McLaren. But technology Chief Adrian Newey then followed up. Brain criticized the rule change in the middle of the season. "It is obvious that we have designed our car to this technique around." Therefore, we have also much to lose. I would say that Renault, McLaren, and we are the most affected. "Ferrari could benefit from."
Now leaked out that Red Bull and Renault have become once again made representations in recent days at the FIA to reduce the ban. It was the engine settings that are allowed from the GP of England. The FIA wanted to set individual limits for opening the throttle and roll pusher, depending on how the manufacturer 2009 voted their engines in the season.
"That was the time before Active blowing of the diffuser," explains FIA Race Director Charlie whiting. "We can assume that the settings at the time exclusively, making the engine as stable as possible". The FIA engineers look at the 2009 identification fields but not as decisive. They are merely an indication for them, how much they allow the engine. So no one with crazy excuses so is why he must open the throttle in the forbidden area still to a certain percentage.
Red bull and Renault have fought each percent. A little opening is necessary to reduce the blow-by and thus the pressure in the Kurbelhaus. But the Association wants to allow more than ten percent of at 12,000 rpm and including any manufacturer. That's enough to guarantee a long life to the engines. And here is the effect on the aerodynamics equal to zero.
Nick Heidfeld is surprised, that Red Bull suddenly so much makes wind to a thing that it has dismissed as not critical. "Perhaps they have found that they lose more than initially anticipated." For his own car, Heidfeld is optimistic: "We are less balance shifts feel than the others, because our exhaust leak earlier."
Ross Brawn would not bet. "We can say not clearly on the basis of the simulation, which exhaust position is more affected." "Our old or the new, with the of Red Bull is comparable." Jenson Button dares to his experiences in the Simulator still a forecast: "It feels like in a car with less downforce." The top teams will lose all. You have optimized their cars for this technique. "We hope now that it meets our opponents more than us."
