Honda is spending $3 billion on an Ohio plant that can build 240,000 more cars a year

Honda will put $3 billion into a new vehicle plant in Union County, Ohio, with room to build 240,000 additional vehicles a year and more than 2,000 new jobs attached. The company announced the project on Nov. 9, 2026, alongside the Ohio governor’s office. Production is expected to begin in 2029, which would be Honda’s 50th year of building vehicles in the U.S.

The start date still depends on final government approvals, a caveat that appears in Honda’s own announcement. The factory would be Honda’s fourth auto plant in Ohio and its ninth auto-related production facility in the U.S., and it is the centerpiece of a broader package that also reaches Alabama, Georgia and Ontario.

Union County site between Marysville and East Liberty

Honda’s global newsroom announcement places the plant on land between the existing East Liberty and Marysville auto plants in central Ohio. The company cited a skilled workforce, a nearby U.S. supplier base, local vehicle development centers, its existing Ohio engine and hybrid operations and the L-H Battery Company joint venture as reasons for the location. It also pointed to $132 million it has invested in research facilities and endowed chairs at The Ohio State University.

Bob Nelson, an executive vice president at American Honda Motor Co., said the investments strengthen America’s role as a cornerstone of Honda’s global future. In the joint release with the state, Nelson added that the spending reflects a commitment to building products close to customers. Gov. Mike DeWine said the company chose Ohio because there are so many advantages to being here, and J.P. Nauseef of JobsOhio described the move as Honda doubling down on Ohio’s workers.

The state release puts a larger number on the Ohio total: 2,390 new jobs and $3.38 billion in new investment once upgrades at the Anna Engine Plant and Honda Transmission Plant-Ohio are counted. The Ohio Tax Credit Authority has approved a tax credit for the project, and Honda plans to pursue JobsOhio assistance, with details to be made public after a final agreement is executed.

Hybrid, gasoline and battery-electric flexibility

Honda designed the plant to build hybrid, gasoline-powered and battery-electric vehicles depending on customer demand, rather than committing the floor to a single powertrain. Carscoops called the project one of the biggest bets in Honda’s U.S. history, a description that fits the arithmetic: Honda says U.S. auto capacity will rise to about 1.3 million vehicles a year and North American capacity to about 1.9 million.

The product plan behind the building is hybrid-heavy. In May 2026 Honda announced 15 new Honda and Acura hybrid models globally by 2030, with North America a primary market. Autoblog’s report on the investment adds that Honda is developing a next-generation V6 hybrid system for larger North American models, expected to improve fuel economy by more than 30% and acceleration by more than 10% against comparable gasoline versions, and that it could reach the Pilot, Passport and Ridgeline.

Retooling in Alabama, Anna, Georgia and Alliston

The new factory is one piece. Honda’s Alabama Auto Plant is being retooled for a new V6 hybrid engine and higher engine capacity, and its Line 1 will be upgraded to build the Passport, which today is built only on Line 2. The Anna Engine Plant in Ohio will retool a line for a next-generation four-cylinder Atkinson-cycle engine for compact and midsize vehicles, and a parts consolidation center is expected to open there next year.

Transmission Plant-Ohio will convert a transmission line into a second hybrid-system line, raising hybrid-system capacity by 250%, with a next-generation hybrid system entering production next year. Transmission Plant-Georgia will make next-generation hybrid systems for larger vehicles in coming years on a new assembly line.

In Canada, Autoblog reports that Honda is investing $166 million CAD in its Alliston, Ontario, plants as part of a broader $867 million CAD commitment. Alliston built 401,000 vehicles in 2025, including the Civic and CR-V and their hybrid variants, and supports a workforce of more than 4,000. Honda’s release says the site will be retooled for next-generation hybrid and gasoline models and will resume engine manufacturing. Public-radio coverage in Columbus from WOSU framed the Ohio plant as a hybrid-production expansion near Marysville.

Some arithmetic puts the scale in view. The 240,000-vehicle annual capacity is about 18% of the 1.3 million vehicles Honda says its U.S. auto capacity will reach, and it is a bit more than half of the 401,000 vehicles the Alliston plants built in 2025. A plant of that size, planned for 2029, is a long-dated commitment made while the powertrain mix of the market is still moving, which is the reason Honda built the flexibility to switch between hybrid, gasoline and battery-electric output into the design.

Ohio’s role in the package extends past assembly. Honda’s release notes that the state already hosts its engine and hybrid operations, and the Anna and Transmission Plant-Ohio upgrades tie the new plant to parts made nearby. Locating the factory between East Liberty and Marysville keeps final assembly within reach of those suppliers and of the vehicle development centers in Ohio and California that Honda says are working on multiple new Honda and Acura models.

Honda’s announcement does not say which models the Union County plant will build, and the JobsOhio assistance package remains unsettled until a final agreement is signed.
