These prices are 1:1 match to the ID.4. If ID.4 can manage almost 100k units a year I don't see why bZ4X can't. In terms of raw specs, bZ4X soundly beats the ID.4 that's why I think they are so confident with it. It's one size segment larger, is lighter, has longer range, more power for same price, better efficiency, comparable equipment (although ID.4 has a really cool AR-HUD system) and much better interior quality. Apart from the top level AWD trim (220kW) the ID.4 is just worse, and that model availability is so poor it might as well be vaporware.
Given the trash economy this year of course they need quite generous discounts to push this volume, I think 30k in 8 months may be a generous guess.
Difference between ChDM bZ4X and International bZ4X:
SR version has 50.3kWh battery and 400km CLTC range, LR version has 66.7kWh battery and 615km CLTC range. It's not specified whether the capacity is usable or total. This converts to ~320km WLTC and ~500km WLTC, respectively. Like the ID.4 Crozz the SR version is never worth it because you save 10% for 1/3 less range.
Batteries are sourced from CATL so DC fast charge is capped to 100kW like USDM bZ4X AWD. Energy density is 152Wh/kg so it's surprisingly among the best on the market. As expected, the energy efficiency is at the very top.
