My problem is that I won't drive a 25 mph car in 45/65 mph traffic.
I won't drive anything that can be out accelerated by a bicycle.
And I won't pay $90,000 or even $40,000 for any car new or used.
I suppose that as a point of pride I won't drive anything that looks like the dog drug it home either.
I did a fair bit of research before-as far as finding usable motor and control combinations and consider what I would put a system in.
My calculations got to putting more than half the price of a decent relatively efficient new car into an older body with only moderate range and performance.
If you want to research something, try the energy cost of generating the electricity to charge up one of these moderate efficiency cars. Not talking $$s here
Don't forget to include the energy cost of mining and transporting the coal or natural gas to generate the electricity. And don't forget the transmission losses down the lines and thru the substations and transformers.
I'll bet that the "carbon" costs are pretty close to ethanol or even some of the refined fuels.
