Toyota Plans $400-Million Engine Plant: The plant, to be built on a 230-acre site northwest of Charleston, W.Va., will employ 300 workers to build four-cylinder engines for Corolla cars beginning in late 1998, the auto maker said. It will be Toyota Motor Corp.’s third engine-manufacturing plant in North America. The Tokyo-based company now builds engines at factories in Georgetown, Ky., and Cambridge, Canada. Those plants also assemble Avalon, Camry and Corolla autos. The West Virginia factory will enable Toyota to supply all its North American-built Corollas with locally produced engines. About 57% of the cars and trucks Toyota sells in the U.S. are built here. The company said it has invested $5.8 billion in the United States.
