What I have been trying to tell people, Hummer is stretching to go 350... She's a guzzler...
guess you need to find a big hill and use regen breaks to get up to 350.

Side note: I did manage to get an extra 12 miles out my mach E coming down 80W from Donner summit while using one pedal driving. Im sure i spent more than that getting to the top tho

Do you think the range of the SUV will be slightly better? Only asking because it is a little smaller so it will weigh a little less too.
Smaller battery in the SUV, 20 modules versus 24. It will be lighter though.

The E1 is also coming with aggressive off road tires, if you change those out it will improve the range. For example, the Rivian is rated at 316 miles with 21 inch all season road tires, but they indicate a 10-15% reduction in range with the 20 inch all terrain tires. Those more aggressive tires increase the rolling friction coefficient.

Exactly right, thats why GM analytical models missed on the Hummer EV range, it's likely the tires and rolling resistance. Put some pizza cutters on there and it will go much further, but look silly.

I have no issue with it. When I get mine, 334 miles of range will be more than I'll need in 99% of situations. And once the battery tech advances, I'll just swap out the new packs with the current ones since GM designed them to be modular, give it a few software adjustments...and boom, 480 mile Hummer EV.

Love your enthusiasm, but you realize the battery pack upgrade might cost $30-$50K?

Yes. But I fully expect that number to drop substantially within the next decade.
Umm, you should look at the math. Battery costs will drop per kWh, but to get more range you need more kWh. if you figure getting 50% more kWh your cost will be almost the same with GM's proposed cost reductions. Also when GM quotes battery cost, they are quoting their wholesale cost and not the retail installed cost. On top of that, to get to the holy grail solid state technology might require new modules as solid state will come in prismatic format instead of pouch, so yes, theoretically you could upgrade the battery, but thinking you will get 50% more kWh for less money is likely a pipe dream. not to mention, for the forceable future GM will be battery constrained for production and warranty, so low retail prices in the secondary market are not likely.
