Good news for fans of big American sedans: GM has announced that it will extend production at the Detroit-Hamtramck plant for another six months.

As a result, the Cadillac CT6 luxury sedan and Chevrolet Impala full-size sedan will remain in production at the Michigan plant until the beginning of 2020; originally, production for these vehicles was scheduled to end in June.

“GM notified employees, suppliers and dealers today that the completion of Impala and CT6 production at Detroit/Hamtramck will extend into January 2020,” the company announced in a statement. “We are balancing production timing while continuing the availability of Cadillac advanced technology features currently included in the CT6-V, the Blackwing Twin-Turbo V-8 and Super Cruise,” GM added.

The announcement means the CT6 and Impala get a new lease of life in the United States for at least another six months. In the meantime, GM will likely arrange alternative production sites for the CT6. Company execs said earlier this year that GM never meant to discontinue the luxury sedan, which was only introduced in 2016 and received its first facelift for the 2019 model year.

We’re not so sure the Impala will live on for long, though. The full-size sedan entered production in 2013 as a 2014 model year, so it’s nearing the end of its lifecycle. Add to that its dwindling sales, and it’s not hard to anticipate the Impala’s demise when production ends in January 2020 at Detroit-Hamtramck.

While there’s a glimmer of hope for the Impala, the fate of the Chevrolet Volt and Buick LaCrosse, which are also built at the same plant, seems sealed. GM’s statement says nothing about the Volt and LaCrosse, which means they will go out of production on March 1, as originally planned. We’ve contacted GM asking them to confirm that date and will update this story as soon as we get a reply.
