GM has just announced the location of its third electric vehicle manufacturing plant in the US, after its Detroit-Hamtramck plant - recently renamed "Factory ZERO" - and Orion Assembly, both of which are in southeast Michigan.

GM's Spring Hill plant in Tennessee has been tapped as the next manufacturing hub in the company's pure-electric vehicle onslaught. The factory will receive a $2 billion investment to cover expansions to its paint and body shops, and upgrades to its machines, conveyors, controls, and tooling as it prepares to undertake production of the all-new Cadillac Lyriq electric crossover.

Spring Hill is a fitting location for Cadillac Lyriq production, not least of all because the plant already builds the Cadillac XT5 and XT6 crossover models. The GMC Acadia, which is currently built at Spring Hill, will be moved to GM's Lansing Delta Township Assembly Plant with the launch of the all-new third-generation model.

The Lyriq seems destined to be a higher-volume EV than either the flagship Cadillac Celestiq electric sedan, or even the GMC Hummer, which was just revealed with a starting price above $110k for the special Edition 1 trim. While we still don't know what the Celestiq or the Lyriq will cost, it's worth noting that the Celestiq will be hand-built, implying a level of luxury not intended for mass consumption.

Back in July, GM announced another critical site in its EV strategy: a battery cell manufacturing plant in Lordstown, Ohio. Born out of a joint venture with LG Chem dubbed Ultium Cells LLC, the joint venture is tasked with producing the advanced, next-generation Ultium batteries that will power GM's next-generation electric vehicles.

With Ultium, GM is chasing a cost-per-energy ratio of $100 per kilowatt-hour, which is the level at which many believe EVs could reach price parity with internal combustion cars.

If you're excited about the Cadillac Lyriq, you might not want to hold your breath; the vehicle isn't expected to launch until late in 2022 as a 2023 model.
