BS. Rank BS.
Not BS. Five miles per kwh is achievable in the real world for electric vehicles. A five passenger sedan should use less energy than a Rav4 EV, and here is a real-world report on the Rav4 EV:
Notice this paragraph:
"My range record (and I don't try for max range very often!) per charge was accomplished 08.21.05. I drove 133 miles on 100% SOC. Two people in the car, plus the portable charger in back. Twisty, hilly drive with many stops at the beginning and end. Heavy AC use for one full leg of the two-way trip. Final score: 191 Wh/mile consumed = 5.2 miles per KWh"
Or the GM EV1 which used only 164wh/mile:

Even the Dodge TEVan only used 400wh/mile. Certainly a well-designed five passenger sedan would have better aerodynamics than a mini-van. Even the TEVan would cost only 4 cents per mile for the electricity -- equivalent to 80 cents per gallon gasoline for the regular ICE mini-van.
The cost of the electricity is minor compared to the cost of battery replacement.
