Formula One boss Max Mosley is confident of pushing through the raft of changes he has proposed for 2008.
Mosley says changes will happen whether the teams like it or not
Mosley is meeting F1 team owners next month to discuss his proposals to cut speeds and costs and improve racing.
"Quite a few will agree to a lot of the changes even without much persuasion, but it doesn't really matter," he said.
"That's because from 1 January 2008 the Concorde Agreement (F1's constitution) is no longer in force so the FIA can do whatever it wants."
Mosley, who was speaking to BBC Radio Five Live, added: "That will be the rule book for the 2008 Formula One world championship at which point people will have to decide whether they want to enter or not."
The team owners will discuss the changes with Mosley in Monaco on 4 May, and the talks are bound up with the threat of the sport's car manufacturers to set up a breakaway world championship in 2008.
DaimlerChrysler (McLaren-Mercedes), Fiat (Ferrari), Ford
(Jaguar), Renault and BMW (Williams) have pulled out of talks with F1's commercial rights holders aimed at giving them some shares in the sport.
"It's really all about equable distribution of the revenues," said McLaren boss Ron Dennis.
"We have talked about costs a lot and want to bring our budgets down but cost cutting is really a smoke screen in this case.
"Any new agreement must go hand-in-hand with an equable and fair share of the revenues."
Mosley said his aim is to "get the power and the grip down and allow the aerodynamics less influence.
"All of these things should make the racing closer and more exciting, but at the same time for the costs to come down dramatically, which will reduce the difference between the top teams and the teams with smaller budgets.
"And we hope the combination of all those things will make the racing a great deal more entertaining to watch."
However, the car manufacturers are not happy about some of Mosley's proposals.
Among the controversial ones are reducing the capacity of the engines from three-litre V10s to 2.4-litre V8s and removing electronic driver-aids like traction control and semi-automatic gearboxes.
Mosley added: "I do believe the teams, including the most successful ones such as Ferrari, will agree to the changes we're proposing because they are all suffering because the costs have got completely out of control."
