When I built mine I did a spread sheet.
It's all weight until you get up to highway speeds in excess of 65 miles per
hour on my 86 Celica.

Oooh -- that's a very useful suggestion.
How much does aerodynamics change that? In particular, I'm thinking of a 1964
1/2 Mustang with, I think, roughly a 0.5 cd. Final weight, though, should be
roughly 3,000 pounds, maybe a bit over. And...a 1968 VW Westfalia Campmobile,
probably 4,000+ pounds and (literally!) the aerodynamics of a shoebox.
I've been figuring that better than 500 Wh / mile would be gravy for either.
Not that I'm expecting such low numbers, especially for the Mustang; just that,
if that's what I use, there'll be plenty of "Murphy factor" such that my
surprise at the real-world performance will be pleasant.
(And, those who don't know: I'm looking at a PHEV through-the-ground conversion
for both, retaining the RWD ICE drivetrain and adapting a FWD axle with the
electric motor connected only to that.)
