Nissan has broken ground on an engine plant in Decherd, Tennessee, that is expected to create up to 400 jobs. The plant will assemble 4-cylinder engines for Mercedes-Benz and Infiniti models when production begins in 2014. The engines will be supplied for the Mercedes-Benz C-Class, which is built at a Daimler plant in Tuscaloosa, Alabama. An existing plant in Decherd already makes engines for the Infiniti JX. That plant began powertrain assembly in 1997 and manufactures four-, six- and eight-cylinder engines for all U.S.-produced Nissan and Infiniti vehicles. Nissan and Daimler first began a partnership in April 2010. Nissan’s USA headquarters are in Franklin, Tennessee, just south of Nashville. A manufacturing facility is located in Smyrna.
