249 to 315 mi battery-only
I know the idea is to swap out a battery at given spots along major highways to make “refueling” comparable time wise to getting gas.
But this limited range is a drawback to me.
It makes the car one that really can’t be relied on for trips of any distance.
My recommendation is that you don’t buy one. There are plenty of people who are fine with the range.
Some people won’t buy a Honda or Toyota because there are particular things they don’t like.
That would be a mighty big storage facility!
And the POWER flowing into it would be ENORMUS!
How close together were pony express stations? Where a rider could get freshly fueled HORSEPOWER.
