The Melfi factory would be modernised to reach a daily capacity of 1,600 vehicles, Fiat said. Production of the new models is to start in 2014 and Fiat said the factory eventually could produce four distinct models on its assembly lines.
Fiat's factories in Italy have been running at about half capacity due to the drop in car demand. The Melfi plant, which makes the Punto compact car, has closed for about 150 days this year, sending its 5,500 workers home with reduced pay.
Under a new business plan announced in October, Fiat is shifting its focus in Italy to the export market with an emphasis on higher-profit luxury models. Fiat owns the Alfa Romeo, Maserati and Ferrari brands, and plans to launch two new Maseratis the next generation of the Quattroporte sedan and the smaller Ghibli and a new Alfa, the 4C sportscar, next year.
Marchionne said that the tie-up with Chrysler had given Fiat both access to premium car technology needed to expand its model lineups as well as access to global markets, notably North America and Asia, where Fiat had lagged.
Fiat's plans also include expanding its family of 500 models based on the update of the iconic city car launched in 2007. Fiat three months ago began selling the larger version, the 500L, built in Serbia.
Marchionne said Fiat's investment plan to launch the production of 17 new cars and seven updated models in Italy by 2016 demonstrates ``the sense of responsibility Fiat feels towards the country.''
