FIA President Max Mosley has warned that 'draconian changes' may be needed for Formula One to keep the sport's credibility.The Super Aguri team has already been a casualty and was forced to withdraw due to a lack of funds following the Spanish Grand Prix, and Mosley fears that any more could spell the end.
"I think it would put the sport in an unsustainable position if we lost two more teams," Mosley told BBC Sport.
"At the moment we have 20 cars competing and if we lost two teams we'd have 16 and then it would cease to be a credible grid.
"This hasn't been prompted by the credit crunch. This is something I have been campaigning for for two or three years.
"It had become apparent long before the present economic difficulties that Formula One is unsustainable.
"If we can't get this sorted out by 2010 we will be in serious difficulty. We can survive through 2009, but I'm not to sure about after."
Mosley has called for various cost-cutting measures to be adopted to ensure the sport's survival, adding: "We have various means of making sure the big spenders don't spend so much, but that would mean some draconian measures."
