Ferrari have struggled to match their rivals in 2009
Formula 1 could go on without Ferrari according to Max Mosley, president of motorsport's governing body, the FIA.
The FIA has announced a £40m budget cap for teams from 2010, aspects of which Ferrari president Luca di Montezemolo labelled "fundamentally unfair".
But Mosley, who has led moves to cut F1's costs, said Ferrari would have to obey the new rules or leave the sport.
"The sport could survive without Ferrari," he said. "It would be very sad. It is the Italian national team."
The budget cap, to be introduced next season, rewards teams who comply with greater technical freedom and unlimited out-of-season testing.
WHAT THE CAP WON'T COVER
Next season's £40m budget cap covers the majority of team expenditure, with some important exceptions:
Salaries for race drivers
plus test drivers and costs of young driver programmes
Fines or penalties
imposed by the FIA
the team can demonstrate had no influence on its performance
Teams who exceed the limit - which does not cover some expenses such as driver salaries, fines, and marketing - do not face any fixed penalties, but will have their fate decided by the FIA depending on the degree of their overspend.
Ferrari have threatened to oppose the new initiative, arguing it will unfairly penalise their team, but Mosley told the Financial Times he believed the cost cap was "here to stay".
He added: "I hope and think that when a team goes to its board and says, 'I want to go to war with the FIA, because I want to be able to spend £100m more than the FIA want me to spend,' then the board will say, 'why can't you spend £40m if the other teams can do it?'"
Independent F1 teams such as Brawn GP have supported the measures, with current championship leader Jenson Button telling BBC Sport he backed Mosley's budget cap.
"For the manufacturers and the bigger teams I'm sure they don't want that, but for teams like Brawn we need that for the future," Button said.
"It's the way F1 has to go in the times that we are experiencing.
"For us and Williams and a few other teams we'll be reasonably happy with the decision - it's going in the direction that we need it to."
The Formula One Teams Association will discuss the new proposals in London on Wednesday.
Teams wishing to compete in next year's championship must notify the FIA between 22 and 29 May and state whether they wish to compete under the cost-cap regulations.
