I've gotten ok at crunching numbers for potential EV projects. I've thought about doing Allerts 125cc Innova in an electric drivetrain myself. That way you don't have to deal with finding the same exact efficient engine in the USA to replicate the efficiency, or emissions for that matter.

(Below i projected these numbers for your car, which is just the VLC with half frontal area.)

Using these batteries as just an example.
Electric Motorsport EV Parts
dimensions in mm: 116 x 46 x 181. 3.2volts 60ah $90 each.
144volt pack using 45 3.2volt 40ah batteries for 8.63kwh, 150lbs, $4,050. 90mile range at projected goal of 75wh/mi 80% total capacity use. 70 mile range at 100wh/mi (the worse end of the spectrum).

Thats a 35-45mile round trip range, which is good. For practical use 40miles total range would suffice 90% of the time. So you could go with a smaller battery and save a couple hundred $, but minimal use of a larger pack will increase the life of the battery.

For comparison a good motorcycle conversion can get 100wh/mi. They have a small frontal area but terrible aerodynamics. There is much room for improvement going from .5cd to 1.6cd, you'll end up using much more energy accelerating than a motorcycle though.
