Fears Honda may have unfair advantage in 2015
"We talked at length [about the issue] with the other manufacturers, but we have not found a solution," said Ferrari team principal Stefano Domenicali.
"We could not enforce Honda to freeze its engine as it is not yet registered in the world of F1 and, above all, an attitude of "closure" would alienate any other manufacturers who might be interested.
"We realise that the Japanese [company] will be able to enjoy a great advantage, being able to adapt its engine as a function of the problems that will be recorded during of the season, but we have not been able to do anything."
