First Generation

The first-generation Cadillac CT6 made its debut at the 2015 New York International Auto Show as a 2016 model year vehicle. It goes on sale in late 2015.

The vehicle uses an all-new, rear-drive vehicle architecture known within GM as the Omega platform.

Before Cadillac officially announced the name of the CT6 while revising the entire nomenclature for its lineup, it was widely believed by enthusiasts and the media that vehicle was going to be called LTS.

In preparation for its new line of large electric vehicles, Cadillac confirmed the discontinuation of the Cadillac CT6 in a memo sent to employees during December 2019. While production was initially scheduled to end in January 2020, a report by 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.

With CT6 production over, the site is began its transition into the Factory ZERO plant, which will produce vehicles such as the Cadillac Lyriq and Cadillac Celestiq.
