Honda's $3 Billion Ohio Plant Adds 240,000 Cars a Year as Hybrid Demand Grows
The new factory opens in 2029, and Honda is also retooling plants in Ohio, Alabama, and Georgia to build more hybrid systems, a V6 hybrid, and new engines.
Honda will spend $3 billion on a fourth auto plant in Ohio, adding room for another 240,000 vehicles a year starting in 2029. The factory is the headline of a wider overhaul across Ohio, Alabama, and Georgia built around one goal: making more hybrids in the U.S., along with the engines and next-generation hybrid systems that go into them.
The new plant will sit on land between Honda's existing East Liberty and Marysville assembly plants in Central Ohio and should bring more than 2,000 new jobs. Honda says production is expected to begin in 2029, pending final government approvals. It becomes the company's ninth auto-related production facility in the country.
Honda isn't locking the site into one powertrain. The lines are being designed to build hybrids, gas cars, and battery-electric vehicles, so the mix can shift with demand. Once the plant is running, Honda puts its U.S. vehicle capacity at roughly 1.3 million a year and its North American capacity at about 1.9 million, up from 1.6 million today, according to the automaker.
What changes at Honda's existing plants
The new building gets the headlines, but most of the near-term work happens inside factories Honda already runs:
- Transmission Plant-Ohio is turning a transmission line into a second hybrid-system line, lifting hybrid-system capacity by 250 percent. It now builds the two-motor system used in the U.S.-made CR-V, Accord, and Civic; a next-generation system for compact and midsize models starts production next year, and a separate system for larger vehicles will follow, with this plant as its lead site.
- Transmission Plant-Georgia, which currently builds the 10-speed automatic for Honda and Acura models, gets a new assembly line for the larger-vehicle hybrid system.
- Anna Engine Plant, Honda's largest engine plant anywhere, is retooling a line for a next-generation four-cylinder Atkinson-cycle engine meant for future compact and midsize cars, plus a parts consolidation center due to open next year.
- Alabama Auto Plant adds production of a new V6 hybrid engine, and Line 1 is being upgraded so it can build the Passport, which today comes only off Line 2. Honda calls it one of the biggest Line 1 overhauls since the plant opened in 2001.
Honda hasn't said which models the new Ohio plant will build, or which vehicles will get the V6 hybrid and the larger hybrid system.
Why hybrids, and why now
The demand case is in Honda's own sales data. American Honda sold a record 32,519 hybrids in October, and hybrids made up 53 percent of CR-V sales, 45 percent of Accord sales, and 36 percent of Civic sales that month, as we noted in our October 2026 sales roundup. In May, Honda said it would launch 15 new Honda and Acura hybrids globally by 2030, with North America as the main market for many of them.
The plan also marks a shift in emphasis from 2022, when Honda committed $700 million to retool Marysville, East Liberty, and Anna for EV production and announced a $3.5 billion battery joint venture with LG Energy Solution, per JobsOhio. That venture, L-H Battery Company, is now set up to make cells for both hybrids and EVs.
Honda's rivals are making similar bets. Toyota pledged up to $10 billion in new U.S. investment over five years in November 2025 and is bringing Corolla Hybrid production to Mississippi, while GM is converting its Lansing Delta Township plant to build hybrids.
Bob Nelson, executive vice president of American Honda, called the package "one of the most significant commitments in our history." Ohio Governor Mike DeWine said Honda could have built the plant anywhere in the world.
Canada is part of the plan too. Honda will retool its Alliston, Ontario, operations for next-generation hybrid and gas models and restart engine production there. Its U.S. release doesn't put a figure on that work; Canadian outlet Auto123 reports an $867 million package backed by federal and Ontario funding.
Still unannounced: the state incentive package for the Ohio site, the plant's first products, and a construction timeline beyond the 2029 start.
