Red Bull accepts F1 rules may be clarified over engine-mapping row

The FIA referred Red Bull to the stewards this morning to investigate irregularities related to the torque map used by the team's Renault engines during qualifying for the German Grand Prix.

Although stewards subsequently deemed the Red Bull to be legal, the statement the FIA issued confirming that no action would be taken was equivocal.

It referred to the fact that the stewards "do not accept all the arguments of the team", suggesting that further action could be taken to curb the torque maps used by Red Bull to force it to change its engine maps.

This could happen before the Hungarian Grand Prix, with the F1 technical working group scheduled to meet in London tomorrow.

"I'm sure there is going to be debate about it," he said when asked by AUTOSPORT whether he expected such a move. "Conveniently, there is a technical working group meeting tomorrow and this will no doubt go on the agenda.

"The regulations are clear, so there could well be further technical directives that are designed to try and further clarify those regulations."

Horner underlined that he had no concerns about the legality of the car and that suggestions that it was against the spirit of the regulations are irrelevant in this case.

"There's no clause in the regulations that refers to the spirit of the regulations," said Horner.

"The regulations are straightforward, it's either in or out. It can't be a little bit in or a little bit out.

"Renault made their case very clearly and the stewards listened to the discussion and looked at all of the evidence, not just from this race but from all of the races from this year and deemed that [the car] was in full compliance."
