Race stewards at the German Grand Prix ruled on Sunday that the Red Bull cars of Sebastian Vettel and Mark Webber are not in breach of regulations.

Earlier on Sunday the F1 technical delegate Jo Bauer said that he had informed race stewards that the cars might have infringed FIA regulations.

In a statement issued by the sport’s governing body FIA Bauer said that there was an issue with the engine maps of the two cars.

“Having examined the engine base torque map of car numbers 01 and 02 it became apparent that the maximum torque output of both engines is significantly less in the mid rpm range than previously seen at other events.

“In my opinion this is therefore in breach of article 5.5.3 of the 2012 Formula 1 technical regulations as the engines are able to deliver more torque at a given engine speed in the mid rpm range.

“Furthermore this new torque map will artificially alter the aerodynamic characteristics of both cars, which is also in contravention of TD 036-11. I am referring this matter to the stewards.” The stewards, however, said that the cars did not breach regulations.

Earler Red Bull team principal Christian Horner told autosport.com that he was not aware that the team had broken any regulations. “I know nothing of such infringements.”
