Luca di Montezemolo says he cannot guarantee Ferrari will still be in formula one in 2013.
The famous Italian marque's president told Auto Bild that the sport "has become too artificial" through deliberately designing tyres that degrade and implementing moveable wings to increase overtaking.
"A steering wheel is now a computer covered in buttons," said Montezemolo, "and the fans no longer understand."
He then referred to the expiring Concorde Agreement.
"The contracts expire at the end of 2012. We need to discuss now how to proceed.
"Ferrari will continue to be there, so long as the sport gives us back something for the development of technology of our production cars. Otherwise not," said Montezemolo.
