Good find Shaved Ice! I hope Edition 1 makes it to the Southeast - would definitely check it out and report back =). I hope the Bolt recall does not affect the projected delivery of the Hummer EV.

Yea I hope it doesn’t delay it as well. I am not sure where the batteries are made, but I think somewhere in Michigan. The first Hummer batteries are not coming from Lordstown yet. I don’t know where the Hummer batteries are coming from at first or if they come from the same factory whether not they are in the same line (probably not). But, I would think that all their battery manufacturing people may be helping out to help fix the Bolt issue. I guess that’s a long way of saying I don’t know, but think it may slow it down due to manpower issues? 😢

GM is in a weird dilemma. If they delay the Hummer too much, it becomes outdated in range and tech by competitors. There are already two features the later releases have that the ED1 doesn’t: ability to export power for home and e-locker instead of virtual locker (can’t remember if front or rear). Additionally, the longer the ED1 release takes, the less time between it and subsequent models (unless they just delay those as well).

I hope they craft a press release around how the tech in the Hummer is completely different than the Bolt and just release the Hummer on schedule.

This Bolt situation really throws a wrench in everything EV for GM, and is a black eye for GM, LG, and really the entire EV movement. How does LG feel about this recall? Does LG feel a fire here and there is just the cost of doing business? Will this destroy GM's relationship with LG? and if it does destroy GM's relationship with LG, what does that mean for UltiumCell going forward? This is very touchy, and I am sure GM and LG are discussing this right now as we speak, this is one of those situations that will not be engineer to engineer, but CEO to CEO as this is a disaster for both companies. LG has a bigger issue too, at what point are they on the hook for the Audi, VW, Porsche fires also that have happened in similar circumstances?

Edit: I forgot I-pace, a couple of those have gone up in smoke too while charging.

Virtual locker is better, it has to be virtual on the 3 motor Hummer because 1 independent motor drives each rear wheel. If you locked them together there is no more torque vectoring.


Edit: I am sure GM would like to craft that press release, and the Ultium battery system is completely different then the Bolt's system (different cell design, chemistry, BMS, cooling, everything is different), however I think the big question marks are about GM' and LG's relationship, quality control, and acceptable risks.

Thanks. I misread the GMC article on the off-road package.

Some of these terms are easy to misunderstand, and I have seen several people on forums bash the HummerEV for its "virtual" locker, not realizing that is the very ultimate way to do a locker for efficiency and performance under all circumstances. There are downsides to mechanical lockers and E-lockers, but there is no downside to a virtual locker. No Ice vehicle electronic differential can compete with independent computer controlled motors driving each wheel. Sometimes perception of a term (virtual), and the reality are not the same.

The Rivian has a 4 channel system, with separate motors driving all 4 wheels, which for control cannot be beat. I heard GM engineers say they did not see an advantage to such a system, but common sense tells me 4 channel control is the ultimate. I do to see any downside to Rivian's 4 channel system, other then maybe extra weight and complexity.

The Bolt batteries are made in an LG plant in Holland Michigan. I am not sure where the initial Ultium packs will be made. It could be they are making them in Holland until the Ohio plant opens. Itwouldl make sense since they need special clean rooms.

Yes, the initial Ultium cells are being made in Holland. This is the reason for the planned slow Hummer Ev rollout, and much later for the SUV. I do not think GM plans any serious production from Lordstown until mid 2022, and GM guided full production would not be reached until 1st half 2023.
