Bernie Ecclestone says he is prepared to go up against the manufacturers to enforce a change in the regulations if they cannot come up with a satisfactory alternative to the independent engine plans.

The F1 chief has long been campaigning for changes in the current engine regulations, which he says has made the sport too expensive and doesn't provide enough of a spectacle. It is a view in part shared by FIA president Jean Todt, who supports the concept but not the cost or the restricted availability.

Together they have proposed an alternative engine developed independently and to a cheaper specification that can made available to all teams. This was subsequently turned down by the Strategy Group, which will now wait for the four manufacturers - Mercedes, Honda, Renault and Ferrari - to come up with their own proposal aimed at primarily cutting costs.

However, since then, the World Motor Sport Council have handed Todt and Ecclestone a mandate with which they can wield more power over the manufacturers when it comes to 'pressing issues', potentially including the engine regulations.

Indeed, Ecclestone is clear that change is necessary, saying he is primed to take the manufacturers on regardless of whether the mandate is powerful enough to do so.

What we are trying to do at the moment is to get regulations for a new engine that is the same for everyone," Ecclestone told Sky Sports News. "We don't want different engines for different teams if we don't have to. If we have to that is what will happen, but that is what we would rather not happen."

"If they don't then maybe the FIA will have to write the regulations. If you like it, good, if you don't, sorry, but you've a choice of stop [competing in F1] or you can arbitrate."

Though he has established a firm alliance with former foe Todt in an effort to exert more power over the manufacturers, Ecclestone saved some harsh words for the FIA president, who he says is too focused on keeping 'everyone happy'.

"The problem with Jean is that if there is a problem he likes to have things very democratic. He wants everyone to be happy and everyone to agree, whereas when Max [Mosley] was in charge he hoped that he was leading the right decisions and hoped people agreed."
