Despite November being the highest production month for Hummer EVs so far, no Hummers were built by GM in December.
Interestingly, GMC Hummer EV production reached its highest level yet in November of the 2022 calendar year, during which time 1,455 units were built. At the same time, GM took GMC Hummer EV production offline in late November to begin upgrading the Factory Zero facility for production of the Chevy Silverado EV and GMC Sierra EV. As a result, no new units of the GMC Hummer EV were produced in the month of December, 2022. As a reminder, the GMC Hummer EV rides on the GM BT1 platform, the same underpinnings as the Chevy Silverado EV and GMC Sierra EV.
Check out the table below for a more thorough breakdown of GMC Hummer EV production at the GM Factory Zero plant. The table also includes production of the all-electric Cadillac Lyriq crossover, which is assembled at the GM Spring Hill plant in Tennessee. Both models utilize GM Ultium batteries and GM Ultium drive motors:
