Speaking at the Ferrari World finals in Valencia, di Montezemolo was unhappy at the lack of testing for young drivers.
"There are things that aren’t going well in this sport and the moment has arrived to clarify these once and for all in the appropriate places. We can no longer have a situation in which the transfer of technology from the track to the street is reduced to the bare minimum, engines and gearboxes are always the same and the aerodynamics no longer has anything to do with research for road cars," he said.
"Moreover, it cannot be that in this sport you can’t test."
"Our patience has run out so someone needs to think about whether they want Formula 1 still to have companies that invest and consider it the most advanced research bench for its own cars – as Ferrari has always done since 1950."
di Montezemolo hinted that 82 year old Ecclestone is too old to run the sport.
"We are constructors, not sponsors: I’m no longer happy that we can’t do testing on tarmac and that you can’t give any chance for young drivers to emerge – since some people have used the expression “It’s a joke” in recent days, I would like to say that this is the real “joke”. Yes, I’m referring to one of Ecclestone’s phrases: my father always taught me that you have to have respect your elders, above all when they reach the point that they can no longer control their words. So I will stop there. Certainly, old age is often incompatible with certain roles and responsibilities."
