The rivalry between Ford and General Motors has long been measured in sales charts and pickup truck bragging rights. Now it is increasingly defined by a more politically charged metric: which company can credibly claim to build more of its vehicles in the United States. As tariffs, supply chain shocks, and new “Made in America” rankings reshape the landscape, the contest over domestic production has become as central to their brands as horsepower or range.

Behind the slogans, however, lies a complicated reality. Counting where a vehicle is “from” involves not only final assembly, but also where its parts are sourced, how its workforce is distributed, and how trade policy nudges factories across borders. The latest moves by General Motors to overtake Ford in U.S. output, and the growing prominence of independent indexes that score how “American” a car really is, show how high the stakes have become.

GM’s bid to seize the U.S. production crown

General Motors has put a clear target on Ford’s back by signaling that it expects to build more vehicles in the United States than its longtime rival. Executives have framed the goal as both a strategic response to President Donald Trump’s tariffs and a statement about the company’s manufacturing identity. By shifting volume into American plants, GM is not only chasing a marketing edge, it is also trying to blunt the financial hit from trade policy that has raised the cost of importing vehicles and components.

The company has outlined plans to add production of gas powered crossovers that are currently built in Mexico to facilities in Kansas and other U.S. locations. That reallocation is designed to reduce exposure to tariffs while increasing the share of American assembled vehicles in GM’s portfolio, a shift that would take the long held title of top U.S. producer away from Ford. GM has also emphasized that a higher domestic build mix would position it as a larger exporter of American assembled vehicles, tying its strategy to the promise of more jobs and investment in U.S. communities.

Ford’s legacy advantage and the risk of losing it

Ford has for years leaned on its reputation as the automaker that builds more vehicles in the United States than any other company, a claim that has resonated with buyers of F Series pickups and other high volume models. That status has been central to Ford’s identity as a family nameplate rooted in Midwestern factories and unionized assembly lines. If General Motors succeeds in overtaking Ford on U.S. production, it would undercut one of Ford’s most powerful talking points at a moment when domestic manufacturing is under intense political scrutiny.

The potential shift also exposes how vulnerable legacy advantages can be when trade rules and cost structures change. Ford has invested heavily in North American plants, but it has also relied on a web of cross border production that includes facilities in Mexico and Canada. GM’s decision to pull some crossover output back from Mexico to Kansas and other U.S. sites highlights how quickly the balance can move when tariffs alter the math. For Ford, matching that pivot would likely require its own reconfiguration of where key models are built, or a renewed emphasis on the American content of its existing U.S. assembled vehicles.

What “built in America” really measures now

Even as Ford and GM trade barbs over who builds more vehicles on U.S. soil, independent researchers are complicating the picture of what it means for a car to be American. The Made in America Auto Index developed at the Kogod School of Business evaluates vehicles on a range of factors that go beyond final assembly, including the percentage of domestic parts, the location of research and development, and the nationality of the manufacturer. In the 2025 edition of that index, the Tesla Model 3 is ranked as the most American made car, underscoring how newer players can top traditional Detroit brands on this metric.

The same research shows that the top ten most American made vehicles include multiple models from companies that are not historically associated with Detroit, reflecting how global automakers have embedded themselves in U.S. manufacturing. A related study cited by Jamie L. LaReau in the Detroit Free Press notes that some foreign carmakers now sell vehicles that score higher on American content than models from Ford or General Motors. That analysis points to shifts in domestic sourcing, with some brands increasing their U.S. parts share while others have seen declines in domestic sourcing, and it highlights that a vehicle’s American identity is increasingly quantified rather than assumed.

Tariffs, politics, and the new manufacturing map

The intensifying focus on where vehicles are built cannot be separated from the tariff regime advanced by President Trump. General Motors has explicitly linked its plan to surpass Ford in U.S. production to the need to manage up to $4 billion in expected tariff costs, a figure that concentrates minds in boardrooms and on factory floors. By moving production of gas powered crossovers from Mexico to Kansas and other American plants, GM is effectively redrawing its manufacturing map to align with the new trade environment, while also positioning itself as a beneficiary of policies that favor domestic output.

For policymakers, the GM Ford rivalry over U.S. production offers a tangible example of how tariffs and industrial policy ripple through corporate decisions. Communities in Kansas and other states that stand to gain new crossover lines are likely to welcome the additional jobs and investment, while Mexican plants that lose volume will feel the downside of the shift. At the same time, the broader supply chain remains global, and even vehicles assembled in the United States often rely on components sourced from multiple countries. That tension between political incentives to localize production and the economic logic of global sourcing will continue to shape how both Ford and GM configure their factories.

Consumers, perception, and the next phase of the rivalry

For car buyers, the question of which company builds more vehicles in America is no longer answered by brand heritage alone. Tools like the Made in America Auto Index and reporting that tracks domestic content give shoppers a more granular view of how much of a given model is truly American. When a Tesla Model 3 tops the index and some foreign branded vehicles rank ahead of Detroit stalwarts, it challenges assumptions that a familiar badge automatically signals higher U.S. content. That shift in perception could influence purchasing decisions, especially among consumers who prioritize domestic manufacturing as part of their values.

Ford and General Motors are responding by weaving domestic production more tightly into their marketing and product planning. GM’s push to add crossover production in Kansas and other U.S. plants is being framed as good news for American workers and communities, while Ford continues to highlight the scale of its U.S. manufacturing footprint and the role of its trucks and SUVs in supporting domestic jobs. As tariffs, indexes, and consumer expectations evolve, the contest between the two automakers is likely to be judged less on who sells the most vehicles overall and more on who can credibly claim that their cars and trucks are, in the fullest sense, made in America.
