A $240-million investment at the Warren transmission plant will enable General Motors to make the electric drive for the next-generation Chevrolet Volt here in Michigan, rather than Mexico, CEO Mary Barra will announce today as part of a sweeping commitment to southeast Michigan.
GM also will invest an additional $300 million at unspecified Michigan locations by the end of the year, Barra will say at a speech at the Detroit Economic Club. The moves could create new jobs but those announcements will come at a later date.
