Yeah, the main reason the Bolt is as cheap as it is now is because of its way outdated charge speed. No way they keep that in the next version, and I'm sure they'll bump the price up $5-10K while they're at it.
No argument there. I like the Bolt as is it is. But that doesn't mean they're going to leave well enough alone when they could get more marketing points AND more profits at the same time.
It can charge at up to 55kW, but that's under perfect conditions (largely weather-related) with a very low battery. As that battery charges, it will definitely go down. Also, DCFC is generally used on road trips, which means freeway driving, which means 4 miles per kWH is unlikely.
If I were to drive about 500 miles away (Denver to Lincoln, NE) right now, starting with a full battery and ending at 10%, I'd need to stop 4 times for a total of 3 hours of charging according to A Better Route Planner.
That said, for stuff around town and even trips to Colorado Springs and beyond it's an amazing car. You don't even need to use its full 48A level 2 speeds for it to be awesome, I got by on 1/3 that (16A at 240V) and could still get about 100 miles worth of charge overnight. I'd love to take it on a trip to visit family in Minnesota in summer time too.
