Yes & no, my kei van is an EV with some unfortunate issues at the moment. As a gasser in the UK 32mpg US is much more likely, I have not been able to find the 660cc fuel economy from japan (aka an 05 move 5sp, too bad the japanese language is still a barrier) Also low end torque would not be an issue on a 2000lb van that originally came with a 2cycle engine (not much low end on a 2 cycle)

You'd cut down on weight and cost without the huge battery packs in current hybrids, plus with hub traction motors you'd cut down on complexity, cost, and power transmission loss and the engine, since it only provides power to the generator, can spin at the peak efficiency rpm range. Basically this is how diesel/electric locomotives work.

I would like to convert the Miles zx40 ev to a volt-like vehicle, this would reduce the affects of some unfortunate battery degredation from a collision.
Running it at 42 volts of damaged batteries is no fun.
Ah well, I wonder why the motor is the only cheap part, I would think the whole kabootle would be equally useless and cheap given it only works on a prius, which unless crashed usually never fails.
