We're kinda splitting hairs here. The significance, to me, is that the bolt does not have a very compelling drag coefficient compared to e.g. the Tesla M3 or the Ioniq 6.
Wtf are you talking about? I said budget sedan. Bolt is not a sedan. It doesn't compete with vehicles like the Tesla Model 3 and Hyundai Ioniq 6, which have much lower drag coefficients and consequently significantly longer range despite comparable battery sizes.
