Toyota Motor Manufacturing North America, a division of Japan-based Toyota Motor Corp., is nearing completion of an $800-million expansion of its Princeton, IN assembly plant, which builds its Tundra line of pickup trucks. Located on 1,160 acres, the original plant was built in 1998. The $800-million expansion begun this spring will add 1.8-million square feet of manufacturing capacity to the existing 2-million square foot plant. The plant expansion is predicted to raise the annual production capacity of Tundras and Sequoia SUVs from 120,000 to 200,000 units. The Princeton facility houses stamping, body welding, painting, plastics and assembly operations for the Tundra, Sequoia, and the Sienna minivan, which is scheduled to start production in ‘03. Once the expansion is completed, Toyota's investment at Princeton will total $2 billion, with a capacity of 300,000 units and expected employment of 4,300 people. Current employment at the plant stands at 2,460, said Toyota.
