Toyota Motor Manufacturing North America Inc. (TMMNA), based in Erlanger, Ky., reported that it will expand its Buffalo, W. Va., plant to manufacture V-6 engines. The 300,000-square-foot expansion will entail a $300 million investment and add 300 new jobs. "With our North American vehicle production growing, there is need for increased engine production as well," said TMMNA President Mikio Kitano.
