Following GM’s decision to produce its new line of large electric vehicles at the Detroit-Hamtramck Plant, the automaker confirmed the discontinuation of the Cadillac CT6 in a memo sent to plant employees in December of 2019. While production was initially scheduled to end in January 2020 a report from our sister publication, Cadillac Society, indicated that CT6 production had been extended to mid-February, essentially giving the luxury four-door an extra two weeks on the line. The Chevrolet Impala, Chevy Volt, and Buick LaCrosse, were all discontinued as well.
With CT6 production over, the site is began its transition into GM’s Factory ZERO plant, and will be the launchpad for GM’s multi-brand EV strategy. Notably, the name ‘Factory ZERO’ is a reflection of the advancement towards GM’s zero-crashes, zero-emissions and zero-congestion future. Initial products will be the Cadillac Lyriq, Cruise Origin, and GMC Hummer EV.
