Stellantis has announced a landmark $13 billion investment aimed at significantly expanding its domestic manufacturing capabilities in the United States over the next four years. This substantial commitment represents the largest single investment in the automaker’s history and is designed to bolster its presence across key vehicle segments and enhance its powertrain production. The initiative is projected to create over 5,000 new jobs across manufacturing facilities in Illinois, Ohio, Michigan, and Indiana, reinforcing the company’s strategic focus on the American market.
This ambitious plan is set to introduce five new vehicles to Stellantis’ brand portfolio, including Chrysler, Jeep, and Ram. Beyond new model introductions, the investment will fund the production of a new four-cylinder engine, further solidifying the company’s domestic supply chain. Stellantis forecasts that these measures will increase its annual finished vehicle production capacity by 50% compared to current levels, complementing ongoing efforts to update 19 existing models and improve their engines at U.S. plants through 2029.
The strategic importance of accelerating U.S. growth was highlighted by Stellantis CEO Antonio Filosa, who stated, “Success in America is not just good for Stellantis in the U.S. – it makes us stronger everywhere.” This investment underscores a broader trend of automotive manufacturers prioritizing domestic production, partly in response to economic policies and the potential impact of tariffs on imported vehicles. Stellantis has estimated that tariffs could impose a significant cost, upwards of $1.7 billion, on its operations this year, particularly given that a substantial portion of its U.S. sales last year involved vehicles imported from Mexico and Canada.
A significant portion of the allocated funds, exceeding $600 million, is earmarked for the reopening of the Belvidere Assembly Plant in Illinois. This facility will be reconfigured to expand the production of the Jeep Cherokee and Jeep Compass specifically for the U.S. market, with initial production anticipated to commence in 2027. This particular initiative is expected to generate approximately 3,300 new jobs.
Further diversification of Stellantis’ production is planned. Approximately $400 million will be dedicated to the assembly of a new midsize truck. This vehicle’s production will be relocated to the Toledo Assembly Complex in Ohio, where it will be manufactured alongside the Jeep Wrangler and Jeep Gladiator. This strategic shift is projected to create over 900 jobs, with production launch expected in 2028.
In Michigan, the Warren Truck Assembly Plant is slated to undergo retooling with an investment of nearly $100 million. This will facilitate the development and production of an all-new range-extended electric vehicle and a large SUV with an internal combustion engine, both set to begin production in 2028. This expansion is expected to add more than 900 jobs to the plant, which currently manufactures Jeep’s Wagoneer and Grand Wagoneer models.
Additionally, Stellantis will invest over $100 million across several Kokomo, Indiana facilities to produce the all-new GMET4 EVO four-cylinder engine, commencing in 2026. This investment aims to secure the U.S. as the primary manufacturing hub for this critical powertrain component and is expected to create more than 100 jobs.
