Ferrari president Luca di Montezemolo believes F1's credibility took a knock when Mercedes conducted an "illegal" test and "without even paying the right penalty for it."
The Mercedes test made headlines as did the team's punishment which saw them banned from July's Young Driver Test.
That test later became a trial for the new Pirelli tyres in which all the teams were allowed to run their race drivers for a day, making Merc's punishment a bit more severe.
However, di Montezemolo doesn't believe it was enough especially in light of Merc's three grand prix wins.
"(Next season) we will finally have testing again and not a farce like what we saw this year with one team doing illegal testing without even paying the right penalty for it," he said in an interview with Corriere della Sera.
"In this case, I would have expected more clarity and courage from the FIA.
"On the other hand, the benefits gained by the team that carried out the secret banned testing are watched by everyone: before then, it had not won a single grand prix, then after the test it won three out of five races.
"These are the sort of serious incidents that affect F1's credibility and alter the Championship."
Touching on another area that will "sooner or later" have a major impact on the sport, the Ferrari President spoke of Bernie Ecclestone and life after the F1 supremo.
"Sooner or later a generational change always occurs. It's not too long until we reach the post-Ecclestone era for reasons of statistics. As for the rest, I don't want to talk about it.
"We will have to prepare for a new cycle, capable of tackling the urgent matters and the need for a new F1.
"I believe the management of this sport, which let's not forget is not just a show, should be entrusted to a group of men open to new ideas, who know about racing but also about marketing and communications and are sensitive to the demands of the fans, those who come to the circuits and therefore pay for the tickets and those who watch on TV, while being able to involve the sponsors and not alienate them.
"But be careful, I don't want to have discussions with Ecclestone, I have had some in the recent past, because he was too talkative on the subject of Ferrari, but surprisingly silent on the subject of the illegal tests carried out by Mercedes."
He added: "I know Bernie's strengths and weaknesses, but let's be very clear on one point, no one else will ever do for Formula 1 what Ecclestone has done."
Another man who is doing something for F1 is former Ferrari team boss Jean Todt who replaced Max Mosley as head of the FIA, motorsport's governing body.
And it's a job that di Montezemolo concedes is not an easy one.
"When he was in charge of the race team here, he didn't just do a good job, he did a great one. At the Federation, he has a different job," said the Italian.
"It's not easy, he inherited a divided institution full of tension, from Max Mosley. He has a political mandate, he needs the consensus that will allow him to develop transparency, also when it comes to the rules, in a world as complex as F1."
