GM Extends Production at Detroit Plant through January

General Motors Co. says it will continue making the Cadillac CT6 and Chevrolet Impala large sedans at its Hamtramck, Mich., assembly plant through January—about six months later than previously planned.

Located on the outskirts of Detroit, the facility is one of several the carmaker designated as “unallocated” under a cost-cutting initiative announced last November. GM has been widely criticized by President Donald Trump, unions and local lawmakers, all of whom are calling for the carmaker to find new products for the targeted factories.

During the extension, the Hamtramck plant will focus on vehicles equipped with advanced technology packages, such as the CT6’s twin-turbo V-8 and Super Cruise automated driving system. Output of the Buick LaCrosse sedan and Chevrolet Volt plug-in hybrid at the facility was discontinued this week.

The other GM manufacturing operations identified in last year’s restructuring plan are assembly plants in Lordstown, Ohio, and Oshawa, Ontario; a Warren, Mich., transmission plant; and a Baltimore factory that makes electric motors and hybrid transmissions. The fate of the facilities will be decided this summer in meetings with the United Auto Workers union.
