GM already has prototype Ultium batteries being tested with packs ranging from 50KWH to 200KWH. Their new factory is under construction in Lordstown, this is not vaperware. Some of these batteries have been installed and tested in retrofitted Bolts.Well, Hummer has yet to build a fully functional production model. They can say 100 miles in 10 min, but they haven't been able to demonstrate this at any level.
