Buffalo, W.Va. (AP) -- Toyota Motor Corp. said Monday it will invest $90 million to further expand electric vehicle parts production in West Virginia and Tennessee.

Three months ago, the Japanese automaker announced it would invest $240 million to add a production line dedicated to hybrid systems at its Buffalo, West Virginia, plant, the report said. The latest upgrade includes spending $73 million to assemble about 120,000 rear-mounted motor stators at the plant each year. This is a key component of the motor.

"Toyota is moving rapidly toward an electrified future, and West Virginia will play a key role in that process," David Rozier, president of Toyota Motor West Virginia Manufacturing, said in a statement. Our team embraces this challenge. Toyota clearly has confidence in our ability to take the company to new heights."

A year ago, Toyota reportedly invested $210 million and added 100 jobs at its Buffalo plant to expand production of four - and six-cylinder engines. The factory employs about 2,000 people.

Toyota also said Tuesday it will spend $17 million to add hybrid drive axle and housing capacity at a Jackson, Tenn., plant that employs nearly 400 people.

Toyota said it is committed to offering electric models in its Toyota and Lexus lines by 2025.

In October, Toyota said it planned to invest $1.29 billion to build a new U.S. plant to produce batteries for hybrid and pure electric vehicles, the report said.
