The carmaker first announced the plan for battery production in 2021.

Toyota Motor Corporation has begun production at its $13.9bn North Carolina battery plant as it ramps up hybrid production and confirms plans to invest $10bn over five years in United States manufacturing.

The Tokyo, Japan-based carmaker announced the developments on Wednesday.

It first introduced the plan in December 2021 to produce batteries for its hybrid and electric vehicles (EVs). Batteries from the plant are set to power hybrid versions of the Camry, Corolla Cross, RAV4, and a yet-to-be-announced, all-electric, three-row-battery vehicle. The plant is producing hybrid batteries for factories in Kentucky and a Mazda and Toyota joint venture in Alabama.

“Over the next five years, we are planning an additional investment of $10bn in the US to further grow our manufacturing capabilities, bringing our total investment in this country to over $60bn,” said Ted Ogawa, president of Toyota Motor North America.

Toyota’s 11th US factory, on a 1,850-acre (749-hectare) site, will be able to produce 30 gigawatt-hours of energy annually at full capacity and house 14 battery production lines for plug-in hybrids and full EVs. It will eventually employ 5,000 workers.

Last month in Japan, US President Donald Trump said Toyota planned a $10bn investment in the United States.

“Go out and buy a Toyota,” said Trump, who has been critical of Japanese and other auto imports and has imposed hefty tariffs on imported vehicles.

Toyota has been one of the slowest carmakers to move to full EVs, but has rapidly moved to convert its best-selling vehicles to hybrids.

“We know there is no single path to progress”, Ogawa said on Wednesday.

“That’s why we remain committed to our multi-pathway approach, offering fuel-efficient gas engines, hybrids, plug-in hybrids, battery electronics and fuel cell electronics.”

Other car companies like Volkswagen have said they will add more hybrids as the Trump administration has rescinded EV tax credits and eliminated penalties that incentivised EV sales.

US Transportation Secretary Sean Duffy said at the event that the administration plans to soon propose to ease fuel economy standards, saying prior rules were too aggressive.

Duffy in January signed an order to direct the National Highway Traffic Safety Administration to rescind fuel economy standards issued under former US President Joe Biden, a Democrat, for the 2022-2031 model years that had aimed to drastically reduce fuel use for cars and trucks.
