True. But if we do the conversion, you have about 33.7 KWH/ GALLON of gas. So if a gallon of gas cost $3, then a kwh would need to cost about 9 cents to be the same cost as gas. Most of the country has higher electricity costs than that especially California. However, a "gallon" of electricity will get you two to three times as far a gallon of gas. So your cost per mile varies more with where you live .

Wow! Someone was silly enough to pay almost 60 cents/kwh. Prius Prime battery is about 9 kwh. Additionally I'm pretty sure that the Prius is capable of charging the battery while it is running. Flawed logic in your mpge calculation. Mpg vs mpge is a physical number. The cost per mile is a separate issue as I showed above.

And it would need to be smaller or more aerodynamic than the already crazy efficient G1 Insight. Drivetrain could be from a G1 Insight, but then you'd have to fabricate custom mounts, etc. for it. There's a guy on here who swaps Prius drivetrains into classic cars, but his projects take a very long time.
Aerocivic.com might be worth checking out.
