With the November midterms in view, President Donald Trump is doubling down on his favorite economic talking point: that tariffs are rebuilding America’s auto industry. But a closer look at the numbers tells a more complicated story.
On April 21, speaking at a Baltimore shipyard, Trump claimed the United States had gone 44 years without building a single car plant before his presidency — and that his tariffs are now producing “more car plants than we ever have in history.” He also said automakers are leaving Canada, Mexico, Japan, Germany and South Korea to move production to the U.S.
Industry records, company filings and trade-group data reviewed this week show those claims are not supported by history. The U.S. has seen a steady stream of new vehicle factories for decades, and the total number of assembly plants open today is barely different from five years ago.
The idea that America went 44 years without a new car plant is plainly false. Since the late 1970s, when Volkswagen opened a U.S. assembly operation, foreign and domestic automakers have built dozens of plants across the country. Honda, Nissan, Toyota, BMW, Mercedes-Benz and Kia all established U.S. factories during the 1980s and 1990s, and many have expanded or retooled them since.
According to Autos Drive America, a trade group representing international automakers, more than two dozen major new vehicle assembly plants opened in the U.S. over the past four decades. Some were greenfield projects; others were bought and re-equipped, but they were all active production facilities.
“We’ve always made lots and lots of the cars that people are buying here,” said Joshua Hausman, an economics professor at the University of Michigan. “There have been car factories built regularly over the past few decades.”
That does not mean Trump has no wins to point to. During his second term, Rivian broke ground on a second factory in Georgia, and the Hyundai Motor Group Metaplant America opened in the same state. Trump celebrated the Hyundai launch as evidence that “tariffs very strongly work.”
In his first term, Toyota and Mazda announced a joint assembly plant in Huntsville, Alabama, and Volvo opened its first U.S. plant in South Carolina. The White House cites more than $50 billion in automaker investment announcements, including a $10 billion Toyota commitment, a $13 billion Stellantis expansion plan, and roughly $15 billion from Ford, General Motors and Mercedes-Benz.
But not all of that money is going to new assembly lines. The Toyota figure covers operations nationwide and has not been confirmed as a direct plant expansion. Several of the other projects are aimed at electric-vehicle components, battery production or parts supply, not new car-assembly buildings. And the pace of activity is not unusual.
During the Biden administration, Rivian reopened a former Mitsubishi plant in Normal, Illinois; Lucid began production in Casa Grande, Arizona; Tesla opened a new Gigafactory in Austin, Texas; Ford launched the Rouge Electric Vehicle Center in Dearborn, Michigan; and construction began on the BlueOval City complex in Tennessee. GM committed $7 billion to EV and battery facilities in Michigan, and Vietnam’s VinFast selected North Carolina for an EV plant.
Measured by plant count, the industry has barely shifted. Autos Drive America’s most recent tally shows 51 light-vehicle assembly plants operating in the U.S., down slightly from 52 five years earlier. That is hardly the picture of a historic construction boom.
Trump also claimed that automakers are fleeing Japan, Germany, South Korea and other countries for the U.S. In reality, many of the world’s largest carmakers have produced vehicles in America for decades.
Volkswagen started assembling cars in the U.S. in the late 1970s. Honda, Nissan, Toyota and several European manufacturers followed in the 1980s — roughly the same 44-year timeframe Trump referred to. Those companies still build and sell millions of vehicles in the U.S. every year.
The American-owned industry’s struggles date to a loss of market share, not a loss of plant construction. During the 2008 financial crisis, General Motors needed a federal bailout after falling into bankruptcy while foreign-brand plants kept operating. Under both Obama and Trump, the industry recovered in fits and starts; Biden pushed major investments in EVs, many of which were later scaled back because of Trump-era policy changes and slower consumer demand.
Economists and industry analysts say it is too simple to credit tariffs alone for new auto investment.
“The current wave of tariffs has led to relocation of production, but they have not resulted in a tsunami of new assembly plants,” said Sam Fiorani, vice president at AutoForecast Solutions. “Vehicle manufacturers invest for the long haul and not based on one administration’s short-term decisions.”
Building a factory takes years, and trade policy can change quickly. Hausman noted that automakers are likely to hesitate if they expect tariffs to be lowered within months or eliminated by the next administration. And tariffs raise the cost of manufacturing in the U.S. too, since steel, aluminum and many key components are imported.
Higher tariffs on foreign-built vehicles also push up prices at dealerships. Automakers must weigh whether the duties they would pay on imported cars are smaller than the added cost of building in the U.S. with tariff-inflated supplies.
“The global automotive industry is very price sensitive,” Fiorani said. “Tariffs are disrupting the equations used to get to today’s vehicles and making them more expensive by making the affordable choices too expensive to use.”
With midterm elections months away, the tariff debate is unlikely to cool. Republicans point to announced factory projects as proof that Trump’s trade agenda is working; Democrats argue that those projects would have happened anyway and that tariffs raise costs for consumers.
The most telling measure remains the plant count. After years of announcements and ribbon-cuttings, the U.S. is operating about as many vehicle assembly plants as it did before tariffs became a signature issue. Whether future plans translate into actual factories will depend on stable policy, consumer demand, and the still-shifting electric-vehicle market — factors no single trade weapon can fix.
