Ferrari says it will review its participation in Formula One if plans to introduce a standard engine for all teams from 2010 go ahead.
Formula One's governing body wants to slash costs to ensure none of the 10 teams leave the sport.
The FIA has announced a tender for a third-party supplier of engines and transmissions to be used by all teams for three years from 2010.
Ferrari's board agrees costs have to come down but says the sport is based principally on competition and technology development.
Ferrari is controlled by Fiat and won last year's constructors' and drivers' world championships with Kimi Raikkonen taking the individual title.
Raikkonen's team mate Felipe Massa is in the running for this season's title and trails McLaren's championship leader Lewis Hamilton by seven points with the final Grand Prix in Brazil on Sunday.
