Originally known as Toyota Motor Manufacturing USA, TMMK was established in 1986 (the first wholly owned Toyota manufacturing plant in the U.S.) and is Toyota's largest manufacturing facility outside of Japan. It began production in May 1988, building the 1989 model 4-cylinder Camry. In the beginning, the engines were shipped from Japan; however, an on-site engine plant was added in 1990. It presently builds the Avalon sedan, Camry sedan, and Venza crossover. It previously produced the Sienna minivan and Camry Solara coupe and convertible. The factory also produces 4-cylinder and V6 engines and powertrain parts with an annual capacity of 500,000 vehicles and 500,000 engines.
In addition to TMMK, Toyota added Camry production at Subaru of Indiana Automotive, Inc. in 2007 to keep up with demand for the new Camry and increase production capacity of the Camry Hybrid prior to the decline in the automotive industry in the U.S.
Harbour Consulting rated it as the eighth most efficient auto plant in North America in 2006.
