That EV2 will be close to the Rivian in weight! Interesting.
Yeah this sounds more in line with everything!
The Hummer pack (and likely the Silverado packs) will likely be a lot heavier per kWh than what most of the other Ultium-based EV packs for other upcoming GM EV's. (Lyriq, Equinox, etc.). Since the BT1 platform does not use a conventional frame-and-rail structural concept, but an "integrated body-frame-pack" structural concept, the BT1-based Ultium pack structure itself has to be extremely strong. It is the key element to provide extreme torsional stiffness to keep everything together while towing, bouldering, etc. This means the outer frame and crossmembers carrying the modules will be super-strong and have rigid attachments, and likely be heavier than required for BEV3-platform passenger EVs. Also, transmitting almost 2,000 total amps to those three 259-kW motors means massive bus-bars, main contactors, etc, also adding weight. That said, the modules themselves will likely be very similar or identical to Lyriq's . And for recycling, the unique issue is recycling the cells within the modules. Everything else - bus-bars, module cases, pack frames, etc. are either stamped steel or aluminum and recyclable through conventional means.
haha they pulled a Ford!!
I would not put much stock in any of this, When tom does a 70 mph range test and charging tests we will have real data, until then this is nothing more than speculation.
I seem to remember the nominal voltage coming up for some when discussing the battery pack size for the Lucid. So what does that make the Hummer size pack? Is Car and Driver correct?
Ya, same thing, Warren Redlich thought it was max volt X amp hours, which was wrong then, and C & D are wrong.
Nominal voltage should be 360V, so 222kWh. Which makes the 212kWh usable a reasonable number, a 5% buffer.

Hmm according to that it seems the Hummer EV payload is actually 1,487, not the originally quoted 1300.Since the Hummers weight over 8500 pounds they won't have to display the MPGe on the window sticker.
GMC Hummer EV Won't Include MPGe Ratings On Window...
According to a GMC spokesperson, the Hummer EV will not have the MPGe ratings on the window stickers. Apparently a vehicle that has a GVWR of over 8500 poiunds isn't required to display MPG or MPGe numbers. https://www.motor1.com/news/567948/hummer-ev-mpge-window-sticker/ A GMC spokesperson...
Since the battery housing is structural to the vehicle's rigidity - What weight percentage should really be moved from the battery back over to the vehicle?
