Honda Motor Co. said Tuesday its North American production reached 30 million automobiles, a major milestone, since it started operations at the Marysville plant in the U.S. state of Ohio in November 1982.

The Japanese automaker currently operates eight assembly plants in the United States, Canada and Mexico. They produce 11 different models and have a capacity to build 1.92 million units per year.

In 2014, they produced just over 97 percent of all Honda cars, including those under the Acura luxury brand, sold in the United States.

Of the 30 million units, the Marysville factory accounted for around 40 percent.
