Stellantis has expanded its production capabilities at the Atessa plant in Italy, specifically through the integration of the CustomFit Center. This initiative has enabled the production of over 20,000 customized utility vehicles by embedding bespoke bodywork directly into the assembly line in coordination with the company’s Gliwice plant in Poland.

Following the summer break, the Atessa facility reported a daily production rate of approximately 850 vehicles. This follows the conclusion of a solidarity contract on August 1, 2026, after discussions between management and the Fim and Uilm unions. Stellantis has announced planned technical investments and upgrades to the production lines, which will necessitate some scheduled production halts and voluntary overtime to maintain output during facility improvements.
