Does General Motors own part of Toyota?
General Motors does not own any stake in Toyota. The two automakers are independent companies with a history of collaboration, but there is no equity ownership between them today.
Historically, GM and Toyota did collaborate on a major joint venture and pursued other non-equity partnerships over the years. Today, their relationship is defined by collaborative projects rather than ownership stakes.
Historical ties between GM and Toyota
The NUMMI joint venture
The strongest direct ownership link in the past was New United Motor Manufacturing, Inc. (NUMMI), a 50/50 joint venture between General Motors and Toyota that operated a plant in Fremont, California. It began in 1984 and ended in 2010, combining GM’s manufacturing footprint with Toyota’s production techniques.
- Established in 1984 as a 50/50 joint venture between General Motors and Toyota.
- Operated in Fremont, California, producing vehicles for both companies until its closure in 2010.
- Ended during GM’s bankruptcy and strategic overhaul; the Fremont plant was later repurposed and ultimately acquired by Tesla for electric-vehicle production.
NUMMI remains the primary example of a direct equity link between GM and Toyota, and its dissolution marked the end of that era of cross-ownership.
Current status and non-ownership collaboration
Non-ownership collaboration and focus areas
Since NUMMI, GM and Toyota have pursued collaboration without ownership stakes. Their relationship has shifted toward joint development and technology-sharing arrangements in areas such as electric vehicles, batteries, and fuel-cell technology.
- No cross-ownership: GM does not own Toyota, and Toyota does not own GM.
- They engage in non-equity collaboration on next-generation mobility technologies and shared programs.
- Public statements and reporting describe ongoing partnerships without any equity exchange between the companies.
These arrangements indicate a strategic alliance aimed at accelerating future innovations while preserving each company’s independent ownership structure.
Summary
Bottom line: General Motors does not own a stake in Toyota. The two automakers operate as independent entities with a history of collaboration that peaked with the NUMMI joint venture (1984–2010) and has since continued through non-equity partnerships focused on evolving mobility technologies.
