The Italian outfit failed to win a race in 2014 and recently appointed Maurizio Arrivabene as their new team principal after sacking Marco Mattiacci.
There has also been a change in the car with four-time world champion Sebastian Vettel replacing Fernando Alonso.
Marchionne said: "2015 will be a difficult year that will put the team to a real test."
The Fiat Chrysler chief executive, who replaced Luca di Montezemolo as Ferrari chairman in October, continued: "I think 2015 is going to be a reconstitution year. It will be Maurizio's first full year with the team.
"I think hopefully within the next 12 months we will remove all the baggage of uncertainty that is going to plague at least the initial phase of 2015."
Ferrari came fourth in the constructors championship in 2014, behind Mercedes, Red Bull and Williams.
