The Hummer EV is made at the factory Zero in Michigan
The Chevrolet Silverado EV and the GMC Sierra Denali EV will also be made there
Production will stop on June 27 and restart on July 22
The Factory Zero in Hamtramck, Michigan was extensively overhauled about two years ago to transition from building gasoline-powered vehicles to building EVs in preparation for the arrival of the Hummer EV, but not for other models apparently.
The automaker will need to stop the assembly line between the 27th of June and the 22nd of July in order to make changes to the facility in order to be able to manufacture the upcoming Chevrolet Silverado EV and GMC Sierra EV there.
These two vehicles are related to the Hummer EV and to each other, so the reason for the downtime is not because the current assembly line couldn’t build the new models but rather because the factory’s capacity won’t suffice to meet the demand for all three models.
To solve this problem, GM will proceed with the installation of new machinery and tooling to allow for more vehicles to be built at the plant at the same time.
In addition to the two new electric pickups, the Zero factory will also need to build the SUV version of the Hummer EV and it will be the birthplace of the Cruise Origin driverless shuttles.
The modifications that will be conducted in the next month or so will also make it possible for the plant to build its own battery packs with Ultium cells that will be made elsewhere, which will reduce the costs associated with transporting components.
