Ferrari have made a clean-sweep of the top roles in the racing team, in particular after a poor start to the new turbo V6 era.
New chief Marchionne, who in the past days has been involved in a war of words with Ferrari's ousted boss Luca di Montezemolo, is getting the backing of Piero Ferrari even though he has ruffled a few feathers.
"I saw him speaking clearly and honestly, without subterfuge or like a politician," Ferrari told La Gazzetta dello Sport.
"I am excited by the generational change that is underway. Companies evolve, but formula one forces you to renew yourself," said Ferrari.
"Do not forget that at the end of 1961, my father fired the seven top executives and started again, putting the young Mauro Forghieri at the head of everything.
"My father would have understood him (Marchionne) at a glance."
Ferrari added: "Marchionne is a person who hates delays. He works hard, recognising and solving problems instantly. He has many qualities."
Ferrari supports the arrival of Sebastian Vettel, saying the German can "lead the team on the right track".
"I appreciate that he does not have a manager, and lives with his feet on the ground without frills. And he is very fast – you don't win four world championships by chance," he added.
