Ferrari president Luca Di Montezemolo will leave the company next month amid a very disappointing season by the flagship Formula One team. A statement from Ferrari's parent company Fiat-Chrysler said Montezemolo will depart on Oct.13 following Ferrari's 60th anniversary celebration of sales in the United States. Fiat-Chrysler CEO Sergio Marchionne will also take on the Ferrari job in the immediate term. While Ferrari is healthy economically, the F1 team has struggled in recent years and was a long way off the leaders at last weekend's home Italian Grand Prix, where there was a public spat over the team's performance. At the time, Montezemolo insisted he would stay on in the job, but Marchionne said he was "terribly upset" by the F1 team's performance, which he deemed "unacceptable." "Our mutual desire to see Ferrari achieve its true potential on the track has led to misunderstandings which became clearly visible over the last weekend," Marchionne said. Montezemolo's departure is slated for three days before the new merged Fiat-Chrysler company is listed on the New York Stock Exchange.Montezemolo joined Ferrari four decades ago after founding father Enzo Ferrari brought him in as his assistant. After a brief period away from the company, he returned as president in 1991 and over the past 23 years the F1 team has won 14 titles eight constructors' championships and six drivers' titles (five won by Michael Schumacher and one by Kimi Raikkonen).But without a title since 2008, this season has gone from bad to worse, with drivers Fernando Alonso and Raikkonen failing thus far to win a single race.
