Vettel downplays impact of FIA ruling regarding Red Bull's engine mapping

The world champion's team was summoned to see the stewards to explain the characteristics of its engine maps - which FIA technical delegate Jo Bauer did not believe complied with the regulations.

Although the stewards decided that Red Bull had not been in breach of the rules, a subsequently clarification of the situation by the FIA on Wednesday means the team will no longer be allowed to run the settings that it had in Hockenheim.

But despite that decision likely to have some effect on the competitiveness of the team, Vettel believes the differences will be minor - and he insists his engineers are not viewing the matter as seriously as those outside the outfit.

"Obviously there is a lot of talk, and there was some talk Saturday night and Sunday which was not nice for us in terms of race preparation," said Vettel ahead of the Hungarian Grand Prix.

"We only knew an hour before the race what was going to happen, but we took it and obviously it was good for us to start from the grid. It was also clear that probably it was not the last action to be taken.

"But, to be honest, I think there was more of a fuss in writing and talking, than in the mapping in the car."

Vettel concedes, however, that the changes - which will limit the way in which Red Bull Racing can change torque settings to help improve the blowing of gases through its exhaust - will make a difference to the handling of the car.

"Obviously, if you look at the cars this year they are different to last year in terms of regulations, and the way you are forced to put your exhaust in a certain position," he said.

"If you look at what people tried to achieve it is similar to last year, so everyone tries to do his best. But it is not as if the car does not work now any more. I am quite confident that nothing will change.

"But obviously we had what we had in the car in Hockenheim because we believed it was quickest, so it is a little bit different for here. But it is hard to give you a figure: if it is two tenths, half a tenth, or nothing. We cannot measure."
