DECHERD, Tenn. (AP) -- Nissan breaks ground Wednesday on an engine plant in Decherd, Tenn.

The plant will assemble engines for Mercedes-Benz and Infiniti models when production likely begins in 2014. The number of potential employees has not been announced.

The engines will be supplied for the Mercedes-Benz C-Class, which is built at a Daimler plant in Tuscaloosa, Ala.

An existing plant in Decherd already makes engines for the Infiniti JX.

Nissan and Daimler first began a partnership in April 2010.

Nissan's USA headquarters are in Franklin, Tenn., just south of Nashville. A manufacturing facility is at Smyrna just southeast of Nashville.

Decherd is about 80 miles southeast of Nashville.
