But Red Bull team principal Christian Horner said over the course of the weekend in Spain that they had tried 'hot blowing' and abandoned it because it was burning the bodywork - so had stuck with the less influential 'cold-blowing', where the throttles are kept open but fuel is not burnt. This produces significantly less energy and so is less effective than hot blowing.
That means that far from the Silverstone ruling hurting Red Bull, it could actually help them - as their closest rivals,
Ferrari and
McLaren, are both using hot-blowing.
It was already difficult to imagine Red Bull being beaten at
Silverstone - a track that abounds with the sort of long-duration corners of varying speeds that bring out the car's strengths. With these latest revelations, their advantage in Northamptonshire could be even bigger.
