General Motors is terminating production of the full-size Cadillac CT6 and Chevrolet Impala sedans early in 2020, reflecting the realities of an increasingly truck- and utility vehicle-obsessed market. The Cadillac CT6 is that premium brand's flagship sedan offering, making use of some cutting-edge construction techniques that include spot-welding steel and aluminum together - an industry first. It spawned a plug-in-hybrid model as well as a high-performance V-Series car, the Cadillac CT6-V.

Yet despite its top-notch engineering, the CT6 struggled to find its audience in the US market, selling fewer than ten thousand units in two of the last three years. Its final day of production will come in January 2020, according to the Detroit Free Press, despite earlier reports that production of the flagship model would simply move to a different plant.

The Chevrolet Impala, currently in its tenth generation, is a more mainstream offering built on a different, FWD platform. Despite receiving much initial praise, it, too, has struggled to earn its keep in the US market, with sales declining by nearly two thirds between 2014 and 2018. The last of the current-generation Chevrolet Impalas will roll off the line at Detroit-Hamtramck Assembly on February 28, 2020.

More than 800 hourly workers and full-time employees will be laid off as GM's Detroit-Hamtramck plant enters an extensive retooling phase, after which it will start turning out electric vehicles, including GM's first battery-electric pickup truck in mid-to-late 2021. The plant's 753 affected unionized workers will be offered buyout packages or jobs at other GM facilities in Michigan and Ohio, according to a company spokesperson.

For now, it seems as though there are no plans to replace either the Cadillac CT6 nor the Chevrolet Impala in the US market, although GM maintains that it is not discontinuing all sedan model lines like its crosstown rival, Ford. That said, its sedan lineup is thinning considerably; as we reported very recently, the Buick Regal is also facing the axe, disappearing from the US after the 2020 model year.
