Stellantis to Fully Integrate Former Punch Powertrain JV at Mirafiori Plant

Stellantis Europe will officially integrate the former Punch Powertrain joint venture into its internal operations starting July 1, 2026, according to announcements made by FIOM-CGIL and FISMIC unions on May 26. The move affects the Mirafiori manufacturing facility in Turin, where electrified dual-clutch transmissions are produced for hybrid vehicle applications. Around 770 workers associated with the facility will become part of the new internal structure under Stellantis Europe, marking a major operational transition for the company’s hybrid powertrain manufacturing activities in Italy.

The restructuring will also involve the direct transfer of nearly 50 current employees and managers into Stellantis Europe. Workers from the Turin region who are already active at the plant will be formally employed within the newly established internal division. Employees assigned from other regions will continue working through alternative arrangements, including temporary assignments and voluntary transfer mechanisms connected to the Turin production site.

Mirafiori Plant Workforce Transition Overview

The transition represents the end of the existing joint venture structure and places the complete production responsibility under Stellantis Europe. Union representatives described the decision as a strategically important development for the future of the Mirafiori facility and for the continuation of hybrid transmission manufacturing operations. The unions emphasized that maintaining employment protection and long-term professional stability for workers must remain a priority during the integration process.

Key Details of the Stellantis Integration Plan

The restructuring plan introduces organizational changes affecting workforce allocation, operational management, and production oversight at the Mirafiori site. The facility remains focused on electrified dual-clutch transmission production, which continues to play a role in hybrid powertrain strategies across the automotive industry.

Stellantis Mirafiori Integration Summary

Industry observers view the integration as part of a broader effort by Stellantis to streamline internal manufacturing operations while strengthening control over electrified powertrain production. The unions acknowledged the industrial significance of the move for the Turin manufacturing ecosystem but reiterated that workforce continuity, employment safeguards, and career stability should remain central during the transition phase.
