General Motors (GM) manufactures its vehicles across a global network of assembly plants primarily in the United States, Canada, Mexico, and other countries, with key U.S. facilities including Arlington Assembly in Texas for full-size SUVs, Orion Assembly in Michigan for EVs like the Chevrolet Bolt, and Spring Hill Manufacturing in Tennessee for Cadillac models.
Overview of GM's Manufacturing Footprint
GM operates over 50 manufacturing plants and parts facilities across 19 U.S. states, including 11 major vehicle assembly plants that produce nearly two million vehicles annually as of 2025. This network supports both internal combustion engine (ICE) and electric vehicle (EV) production, with recent $4 billion investments announced on June 11, 2025, targeting expansions in Michigan, Kansas, and Tennessee to meet surging demand for popular models like the Chevrolet Equinox and Silverado EV.
In 2014, GM's U.S. plants alone produced 2,053,821 light vehicles, with Michigan accounting for 36% of output, underscoring the state's dominance in the company's operations. Internationally, facilities in Canada and Mexico bolster North American production, while plants in South America, Asia, and Europe handle regional demands.
U.S. Vehicle Assembly Plants
The United States hosts GM's core manufacturing hub, employing nearly one million workers across its facilities. Key plants specialize in high-volume models, adapting to shifts toward electrification.
- Arlington Assembly (Arlington, Texas): Produces Chevrolet Tahoe, Suburban, and GMC Yukon/Yukon XL SUVs, with capacity for over 300,000 units yearly.
- Orion Assembly (Orion Township, Michigan): Shifting to gas-powered full-size SUVs and light-duty pickups starting early 2027; previously focused on Chevrolet Bolt EV.

- Factory ZERO (Detroit-Hamtramck, Michigan): Dedicated EV hub for Silverado EV, Sierra EV, Escalade IQ, and Hummer EV.
- Fort Wayne Assembly (Fort Wayne, Indiana): Chevrolet Silverado and GMC Sierra light- and heavy-duty trucks.
Canadian and Mexican Facilities
GM's North American operations extend to Canada and Mexico for cost efficiency and market proximity. In Canada, Oshawa Assembly reopened November 10, 2021, solely producing Chevrolet Silverado and GMC Sierra pickups, hiring up to 2,500 workers. CAMI Assembly in Ingersoll, Ontario, transitioned to commercial EVs like BrightDrop until idling in April 2025, with future uses under assessment as of January 2026.
Mexico's plants, including Ramos Arizpe and San Luis Potosí, produce crossovers like Chevrolet Equinox and GMC Terrain for export. Silao Assembly focuses on Silverado and Sierra crew cabs, supporting GM's truck lineup.

Historical Evolution of GM Plants
GM's manufacturing began expanding globally in the early 20th century, but U.S. plants like Flint Assembly in Michigan trace roots to 1904, evolving into modern powertrain sites. The 2008 financial crisis led to closures, yet resilience shone through Oshawa's 2019 shutdown and 2021 revival.
- 1908: GM founded, consolidating Buick, Cadillac, and others under one umbrella.
- 1950s: Peak U.S. expansion, with St. Catharines Propulsion Plant opening in 1954 for V6/V8 engines.
- 2010s: Shift to Mexico for compact SUVs; Ramos Arizpe launched Chevrolet Blazer.
- 2020s: EV pivot, with Factory ZERO retooling in 2021 for Ultium battery platforms.
- 2025: $4B investment amid tariffs, boosting capacity to over 2 million U.S. vehicles yearly.
Investments and Future Expansions
On June 11, 2025, GM CEO Mary Barra stated, "This $4 billion investment ensures our plants can flex between gas and electric vehicles to meet customer demand," targeting Orion for SUVs, Fairfax for Equinox, and Spring Hill for Blazer by 2027. These upgrades follow 2024 reelection-driven tariffs, prioritizing domestic production.
"GM's manufacturing network is the backbone of American automotive strength, employing one million and building the future of mobility." - Gerald Johnson, GM EVP Global Manufacturing, 2025.
Powertrain and Parts Facilities
Beyond assembly, GM runs 12 U.S. powertrain plants producing Vortec engines and transmissions. St. Catharines in Canada is North America's largest for V6/V8 engines and GF6 units. Flint and Bay City in Michigan stamp bodies, supporting 16 Michigan facilities overall.
Global Reach Beyond North America
GM's eight-country footprint includes Rayong, Thailand, for Trailblazer trucks, and São Caetano do Sul, Brazil, for regional Onix models. In China, Asaka City builds Spark and Lacetti, adapting to local preferences.
- Argentina (Rosario): Compact cars for South America.
- Brazil (Gravataí): Chevrolet Onix, GM's global bestseller.
- Colombia (Bogotá): Sail and Spark models.
- Ecuador (Quito): Dmax pickups and buses.
Economic Impact
GM plants contributed $50 billion to U.S. economies in 2014 via jobs and suppliers; today, with expansions, this exceeds $70 billion annually. Michigan's 16 plants employ tens of thousands, while Texas's Arlington drives regional growth.
| Region | Plants | Output Share | Key Models |
|---|---|---|---|
| U.S. | 11 assembly | 40% | SUVs, trucks, EVs |
| Canada | 3 | 8% | Silverado, engines |
| Mexico | 4 | 15% | Equinox, Silverado |
| Other | 20+ | 37% | Regional cars |
GM's strategic plant locations optimize logistics, with Midwest hubs feeding truck-heavy U.S. markets and border plants easing NAFTA/USMCA trade. As electrification accelerates, expect further retooling, like CAMI's EV pivot.

Supply Chain Integration
Each plant integrates stamping, welding, painting, and assembly under one roof for efficiency. Wentzville, Missouri, handles midsize trucks like Colorado alongside vans. Global sourcing ensures 60% U.S./Canadian content in many models, per 2025 disclosures.
