Hello Forum, I‘ve been thinking about scenarios where and if the Hummer EV can be taken to remote areas for extended periods, I am thinking 2k miles trips, partially in the wilderness, which would be my primary use case for the Hummer.

I’ve already reserved one, but having second thoughts now about range and availability of chargers where I would take the Hummer, from what I’ve read, it could work but I would have to really get out of my way to the point it might not practical.

What do people think? Should I just stick to my Power Wagon for now?

I personally would not want to venture more than 100-150 miles from a charger. Also, if you are out four wheeling, you are likely to lose a lot of range, especially in sand or loose rocks. If you are just taking dirt roads, then not so much range lose.

I am sure some on this forum will propose taking solar with you for charging, but not very effective in my opinion. And if you are truly in the wilderness, probably a lot of trees or mountains and not great access to sunlight.

Welcome to the forum,

Certainly there are some limitations with any EV and the currently available charging infrastructure. Every persons use case is different, and if you have this limitation a couple times a year for a trip it might not be a big deal to find a compromise. Its like pulling a trailer long distances, if that is something you do a few times a year, no big deal for the inconvenience of stopping every 100 miles to charge, but if you are pulling a trailer long distances every week, stick with a diesel for now.

You are exactly right, solar out in the woods is a not a great idea for the weekend warrior, although if going overnight and doing some 4 wheeling, I think 75 miles from a charger is more reasonable. Remember if you charge to 100% 350 miles of range it takes much longer on a DC charger than 80%, so 290 miles of range is more realistic in the real world unless you have an extra hour to wait to charge that last 20%. Of course we do not know the HummerEV charging curve yet, and GM might surprise us, but in light of the Bolt issues, I think GM will be very conservative on the DC charging curve over 50% SOC, and extremely slow over 80% SOC at least initially. They might build up more confidence as time goes on and update the firmware over the air, but I expect a Tesla like charging curve over 50% SOC initially, which is quite slow compared to cars like the E-Tron which go 150 kW all the way to 80%, and even at 98% are still pulling 50kW.

If I was going to spend more than a few days in the backwoods, I would bring a 9500W generator with me, at least the first few times until you figure out what is doable and what is not.
