Bolt EV was 20K after tax rebate (and that is an US car, ie. it has more safety and other required features than say a 12K car legal in many other countries). Not many people bought. Instead they buy more expensive EVs. While GM probably didn't make much money on each Bolt. Now Equinox EV, something like 28K after tax rebate. Not many people buying. Again they are buying more expensive EVs. And GM probably doesn't make much on the Equinox EVs. Talked with an owner of one - great car, very inexpensive lease, so while being price conscious he went for a pretty loaded config.

So, i think 10-15K car in US has no buyers, and no margin to make it worth for the manufacturer.
