The French carmaker's chairman Louis Schweitzer warned that costs must come down, with a blue-and-yellow clad driver regularly atop the podium.
"We would like to stay (for) a long time," he told Italy's La Gazzetta dello Sport, "but only if we're winning."
Schweitzer then said that the rules must be 'stable', and designed to let even a top team 'save money.'
Schweitzer, 62 - whose comments follow speculation that successor Carlos Ghosn might like to axe the F1 programme - also appeared to encourage Flavio Briatore to stick around beyond 2005.
He said: "I've always approved all his choices." -GMM
