I think there's lot of propaganda from the engineering department that it is entirely possible.The biggest advantage I hope to see with the Ultium pack design and layout is a potential to upgrade from Gen 1 to Gen 2 and beyond. Has anyone seen any information from GM referencing a focus, plan on allowing that. It would be an absolute game changer as far as EV's are concerned and I believe the Ultium design philosophy would allow for it. I have seen discussion of replacing battery modules in the pack and how the system would handle that using the controllers and software, but not the logical step of replacing the entire Ultium battery modules with new gen batteries as part of an upgrade.
It would be, here's 10k get a next gen battery pack upgrade instead of 50k for a new vehicle (Or buy a used vehicle with a 80% capacity battery and then replace the battery pack).
However, environmentally and owner' benefit aside, i definitely do not see, why the marketing and revenue management peeps at GM want to push for that.
Unless, regulation will ask to do so, but in that perspective, car manufacturer has absolutely, no incentive to make that happened.
It's killing their revenue.
But the japanese in the 70s had make that difference, by introducing, reliable cars.
Reliable car that doesn't need to gets repair as much as the domestic one.
So, yes, if GM is willing to step up, and being the industry leader. It shall be a game changer.
But as of now, I doubtful it will happened during my car's life span (probably my son's or grandson' generation).
