Stellantis Saltillo Engine Plant Selected for Global 6.2L HEMI V8 Production

Stellantis Selects Saltillo for Global HEMI V8 Production

Stellantis has confirmed that its Stellantis Saltillo Engine Plant in Ramos Arizpe, Coahuila, Mexico, has been selected as the exclusive global production site for the new 6.2-liter HEMI V8 engine. The powertrain will be used in the Ram 1500 TRX full-size pickup truck, making the facility a key location for production of a high-performance engine within the company’s global manufacturing network. The decision also brings HEMI V8 engine production back to Coahuila and reinforces the strategic importance of the Saltillo operation. The project highlights the plant’s manufacturing capabilities and positions the region as an important center for high-performance powertrain production within Stellantis.

Engine Production and Vehicle Assembly in Coahuila

The new HEMI V8 engine will be manufactured at the Saltillo Engine Plant, while the Ram 1500 TRX will be assembled at Stellantis’ Saltillo Truck Assembly Plant. This arrangement places two critical stages of the vehicle’s manufacturing process within Coahuila, linking engine production and final vehicle assembly in the same regional industrial base. The concentration of these operations is expected to strengthen the connection between the two facilities and support their role in the company’s North American manufacturing network. It also gives the region a direct role in producing and assembling a high-performance pickup and its associated powertrain.

Coahuila Gains Strategic Powertrain Manufacturing Role

According to Stellantis, the project recognizes the technical expertise of the local workforce and the capabilities developed at its Saltillo operations. The return of HEMI V8 production to Coahuila adds another high-performance powertrain program to the plant’s manufacturing activities, while vehicle assembly remains centered at the Saltillo Truck Assembly Plant. By locating engine production and pickup assembly in the same state, the company is reinforcing Coahuila’s position within its North American supply chain. The project therefore connects local manufacturing expertise with a globally significant engine program and continued production of the Ram 1500 TRX full-size pickup truck.
