MARANELLO, Italy (AP) — Stefano Domenicali resigned as Ferrari team principal on Monday and will be replaced by Marco Mattiacci, president of Ferrari North America.
Domenicali stepped down after six years in charge following a poor start to the season.
"There are particular moments in everyone's professional life in which you have to have the courage to make difficult and very agonizing decisions," Domenicali said. "It's time to make an important change. As chief, I take on the responsibility of the situation we are in. It's a decision made with the desire to do something to shake things up and for the good of this group."
Domenicali replaced Jean Todt at the end 2007 and helped Ferrari win the constructors' championship in his first year in charge. However, the team has failed to secure a driver's title under his guidance.
Felipe Massa was close in 2008, while Fernando Alonso lost out in the final race in 2010 and again two years later.
Ferrari has not won a race since Alonso's victory at the Spanish Grand Prix almost a year ago, the team's worst run in nearly 20 years.
