Manufacturing covers the plants, supply chain, labor agreements, and production decisions that shape every Stellantis vehicle. North American assembly (Sterling Heights, Warren Truck, Toledo, Windsor, Brampton, Saltillo, Toluca), Italian facilities (Mirafiori, Pomigliano, Cassino, Melfi), and joint-venture operations in Serbia and Morocco are all tracked here. UAW, Unifor, FIM-CISL, FIOM-CGIL, and other union news is covered alongside plant retooling announcements, model-shift decisions, and capital investment plans. MoparInsiders connects the manufacturing story to its outcomes: see Stellantis for corporate strategy, sales for volume impact, and Ram coverage for truck-plant news (Ram trucks dominate the Detroit-area manufacturing footprint).
