GM Favored Cadillac Lyriq Production Over GMC Hummer EV This Summer

GM is making a pivot to all-electric powertrains, and models like the Cadillac Lyriq and GMC Hummer EV are leading the charge. Notably, GM favored production of the Cadillac Lyriq over the GMC Hummer EV this summer.

For readers who may be unaware, the Cadillac Lyriq and GMC Hummer EV both run on GM’s Ultium technology, including GM Ultium batteries and GM Ultium drive motors. Production of the Cadillac Lyriq takes place at the GM Spring Hill plant in Tennessee, first kicking off this past March, while production of the GMC Hummer EV takes place at the GM Factory Zero plant (previously known as Detroit-Hamtramck), first kicking off last October.

Interestingly, as Cadillac Lyriq production has ramped up over the past few months, it seems as though the limited number of Ultium battery cells GM has on hand were used to build more units of the Cadillac Lyriq, rather than the GMC Hummer EV. In fact, looking at GM’s production numbers for July of 2022, we find the automaker built just 50 units of the GMC Hummer EV Pickup, and 250 units of the Cadillac Lyriq, making for five times the number of units for the Caddy crossover as compared to the GMC off-roader.

Notably, the table above does not include production numbers for the BrightDrop Zevo 600 delivery van, which also utilizes GM Ultium batteries.

Now, as GM Authority reported on September 1st, production has officially begun at the new Ultium Cells plant in Warren, Ohio. The facility employs roughly 800 workers, and was created via a joint partnership between GM and Korean supplier LG Energy Solution. GM previously inaugurated its first global Ultium Cells plant in Shanghai, China last year.

With the new Warren plant open for business, production for both the Cadillac Lyriq and GMC Hummer EV should start ramping up as we head into the fall.

  • It's weird you didn't draw the correlation between Factory Zero being down for upgrades from June 27th and July 22nd to its lower Hummer output in June and July. Granted the outcome of that is more cells available to the Lyriq. But it had nothing to do with prioritization, just availability of cells.

  • Hello GMA team. Great information, thank you! Please provide us readers with any guidance as to where one might be able to see a Cadillac Lyriq in person in the tri-state area (Cadillac House in NYC?) Cadillac dealers don't seem to know.

  • IMO It's a two-fer! The Hummer uses two Ultium battery packs, whereas the Lyric only uses one. So twice as many Lyrics can be built with the limited supply of batteries.

  • With production numbers shown in the table, both are unobtainium. I thought they made test vehicles in greater numbers.

  • Can not understand the rate of production from such a mega corporation with such a backlog of deposits for the LYRIQ.. July 250 , an average of 5 per state.

    • It has nothing to do with GM's ability to build the vehicle. The bottleneck is cells to build the pack. The Ultium cell plant just started producing cells last month.

  • This is very bad for GM. In my AO I have seen multiple Rivian R1T trucks and LUCID Air EVs but have yet to see a single Hummer EV.

    • I feel bad for Rivian. At least GM has a well-known bottleneck - battery cells. Unlike Rivian GM's 40GWh cell plant started serial production last month. So, GM will be able to produce vehicles at faster rates as time goes on. There a reason GM spaced out the releases of the Hummer, Lyriq, Brightdrop, Silverado, Blazer and Equinox EV's. They know when they have battery plants ramping up and coming online.

      Rivian's issues are all over the place.

  • Over the Summer the Hummer plant was shut down in July for upgrades.... that's why more batteries were going to the lyriq....

    You even had an article on that GMA...

  • Doesn't quite add up as they seem to have delivered maybe around 600 hummers, and are late for Spring/Summer estimated deliveries even, while some Falls have gotten build emails but no delivery either yet. Deliveries have taken from 2-5 months even for some to get theirs but its hard to tell as there is not good pattern.

    Overall there must be ~1000+ Hummers sitting in lots somewhere then around Flint just waiting, etc. Ridiculous. If they can't even get 1000 delivered or 250 a quarter delivered easily there is no way logistically they are going to get 20K a year or so built and delivered ha.
