Ferrari president Luca di Montezemolo has threatened to withdraw Formula One's biggest team from the circuit unless the sport changes direction.
Di Montezemolo says in an interview with German magazine AutoBild that the sport had become "too artificial," saying "a steering wheel is now a computer covered in buttons and the fans no longer understand."
FIA is intent on using four-cylinder engines from 2013, something alien to Ferrari's race team and road cars.
Di Montezemolo says Ferrari will stay in Formula One "so long as the sport gives us back something for the development of technology of our production cars. Otherwise not."
