Stellantis is set to present on Monday to unions at Italy's Industry Ministry a reorganization plan for its Turin industrial hub.
The plan includes increasing the production of the Fiat 500 minicar in the site by transferring volumes from Tychy, Poland, and identifying a new mission for the Maserati plant in Grugliasco, La Repubblica reported on Saturday.
Alfa Romeo will adopt a 'built to order' approach producing cars only if there is the final customer, to cut costs, Corriere della Sera wrote on Saturday.
Alfa Romeo CEO Jean-Philippe Imparato told Italian dealers earlier this month that the brand will introduce a new model each year to 2026, starting with the Tonale compact SUV next year.
Stellantis' Italian plants are currently running at a 40 percent of their output capacity, Il Sole 24 Ore reported on Sunday, citing an estimate by FIM Cisl union.
The union said on Friday that the global microchip shortage is causing production stoppages at the company's plants in Italy that are weighing more than the coronavirus lockdown in 2020.
The automaker is prioritizing Turin's Mirafiori factory, where the Fiat New 500 full-electric minicar is built, the union said.
Stellantis was formed in January through the merger of Fiat Chrysler Automobiles and PSA Group.
