While I do agree on you that 55/75 is what we can expect on the first generation of Model 3, I do object to the reasons you give here. The exact range and size of the battery of course unknown to us all, so what you really is saying here is that Elon has promised 215+ EPA miles, so they will not deliver any more then maybe a few miles above 215 EPA miles. The same logic one year ago would judge 215 miles range as an impossible pipe-dream, as Elon had just promised above 200 miles at that time. So I think it is reasonable that the base TM3 will have a range above 215 EPA miles, but how much above is unknown. It may be 220 miles or 250 miles or anything in between, whatever they manage to get out of that "55" battery, how many real and/or usable kWh it can hold.60/80 kWh: This doesn't look possible because the base price is fixed at $35K and the 55 kWh already achieves more than 215 miles. They are not going to give away 5 kWh for free.
