72.8kWh likely means they're using the same CATL pack from the NA AWD bZ4X/Solterra for the UX. Sounds like Toyota doesn't really trust this pack and might be giving it a really big buffer, thus the lower range (among other things). We don't know how much of it is available to really infer its efficiency. Likely Toyota just being its usual conservative self.

I understood you just fine. My point was that the 72.8 kWH battery is an existing battery already in the BZ4X, Toyota didn't go out of their way to design a new larger battery pack for the UX. Economies of scale are at play.
They aren't going to go out of their way to design a new larger battery pack for the BZ unless customers are willing to pony up another few thousand dollars- batteries remain the most expensive component in EV's after all. Which brings me to another point- the UX with the larger battery doesn't have a price yet, but I'm confident it will be significantly more expensive than the current model.

Battery supply is the issue.
Unlike ICEV-based UX, dedicated e-TNGA bZ & RZ can accept battery packs much bigger than 72.8 kWh.
Like you say, to make things worse - these days, the prices of EV’s are ridiculous.
I sore a YouTube video the other day where the battery pack for an UX300e with the old 50+ kWh battery pack costs A$47,000 [US$31,000] to replace!
Hence hybrids will be around for some time yet…

What's even worse is that the UX's new batteries are the same slow-charging CATL ones we get from the AWD BZ- why would they put such a mediocre battery pack in their European Lexus model when the more lowly Toyota BZ sold there uses the superior Panasonic pack?

Nobody said Toyota can't physically design bigger battery packs for the BZ, they're just not going to put them in because it's going to price it completely above its segment. Toyota's EV's are generally woefully inefficient, as the UX and BZ demonstrate, and that speaks more about their conservative and limited engineering prowess with EV's than it does with the actual progress of EV's.

Hence TMC just can’t get their hands on enough Panasonic cells.

Assuming that the RZ, bZ4X, Subaru, UX, and maybe the Toyota version C-HR of the UX is using the same batter, motor at the front...smart move IMO. Amortize the costs across various regions in the world, possible platforms....a smart move on Toyota's part.
lets see the corresponding price increase with the larger battery
