Where does GM get their parts?
GM sources its parts from a vast, multinational network of suppliers and contract manufacturers. A notable portion of its EV battery cells come from Ultium Cells LLC, a joint venture with LG Energy Solution, with additional suppliers under a diversified strategy; globally, components come from suppliers across North America, Europe, and Asia. The exact supplier mix varies by model and year.
GM's global supply chain architecture
GM's procurement operates through Global Purchasing and Supply Chain, coordinating hundreds of Tier 1 suppliers that deliver assemblies, modules, and components to GM manufacturing plants around the world. The network is designed to balance cost, quality, and risk, and to support GM's move toward electrification and software-defined vehicles.
Battery cells and energy storage
Battery cells are a crucial and highly visible part of GM's sourcing strategy, reflecting the shift to electric vehicles. The company has built a diversified battery-supply plan that includes Ultium Cells LLC — a joint venture with LG Energy Solution — supplying cells for many GM EVs, with production launched in the United States. GM has also pursued additional suppliers to expand capacity and regional coverage.
Here are some of the major elements of GM's battery strategy and its partners:
- Ultium Cells LLC (GM-LG Energy Solution joint venture) supplying cells for most GM EVs in North America, with planned expansion to additional plants and capacity.
- Engagement with other battery partners to secure additional capacity and reduce risk, including potential collaborations and sourcing from other battery-cell manufacturers for different models/regions.
- Regionalization to support US and North American EV production, aligning with near-shoring policies and incentives under trade agreements.
In practice, this multi-supplier approach aims to ensure battery supply as GM ramps up EV production, while controlling costs and delivery schedules across its global factories.
Electronics, semiconductors, and software components
Automotive electronics and semiconductors power GM's infotainment, driver-assistance features, and advanced propulsion controls. GM purchases chips, microcontrollers, sensors, and software platforms from a wide set of global suppliers and, for some functions, collaborates with technology partners to integrate silicon and software into its vehicles. The supplier base includes established semiconductor firms and specialized automotive electronics providers, with emphasis on securing supply in times of chip scarcity.
Details on individual suppliers are typically disclosed in GM's supplier disclosures and annual reports, and the lineup evolves with new models and technology platforms.
Engines, transmissions, and drivetrains
Historically, GM sources powertrains and transmission components from a broad set of external suppliers as well as in-house engineering and manufacturing for some platforms. The company maintains long-standing relationships with Tier 1 suppliers in North America, Europe, and Asia to provide engines, transmissions, and propulsion components for its vehicles, including internal combustion, hybrid, and electric drivetrains. These relationships are continually adjusted as products evolve with electrification and new production sites.
Procurement teams work to ensure quality, unit cost, and on-time delivery while maintaining compliance with safety and environmental standards.
Global production footprint and near-shoring
GM's manufacturing network spans the United States, Canada, Mexico, and other countries, with assembly plants and regional logistics hubs designed to optimize cost and supply resilience. The company has pursued near-shoring and regional sourcing to reduce cross-border complexity, improve lead times, and align with supplier diversity initiatives and government incentives for EV manufacturing in North America.
These supply-chain strategies help GM manage global risk, including geopolitical tensions, trade rules, and commodity price volatility, while supporting its broader electrification and software strategy.
How GM manages its supplier network
GM employs a formal supplier-management program that includes supplier selection, performance monitoring, risk assessment, and ongoing collaboration on quality, cost, and innovation. The program emphasizes sustainability and diversity, with goals to work with a broad set of suppliers, including minority- and women-owned businesses, where feasible. The company's procurement teams coordinate global contracts, audits, and supplier development to align with GM's product roadmaps and regulatory requirements.
By maintaining transparent supplier relationships and performance metrics, GM aims to ensure reliability across its model lineup and transitions to EVs and software-defined vehicles.
Summary
GM's parts come from a global, diversified supplier network, with a central emphasis on battery cells from Ultium Cells (GM-LG) for its EVs and a broad mix of electronics, powertrains, and other components sourced from Tier 1 and Tier 2 suppliers around the world. The company continues to regionalize its supply chain and invest in supplier development to support its electrification goals, while balancing cost, quality, and resilience across its production footprint.
