Thanks bearman, great info.
How long does it take to charge the batteries alone?
FWIW my econobox standard gas engine gets 33 mpg, gets the same range and upfront costs $13k, new, back in 2000.
The Prius in EPA tests does about 50 mpg.
This website is very good.
http://www.fueleconomy.gov/feg/bestworst.shtml$44k doesn't include dealer 'prep charges' and taxes when sold.
The top dog, Nissan Leaf?, does 100 mpg, its $33k base minus $8K in Fed tax benefits, or ~ $25k, not including dealer prep, taxes and options. Before you jump to them look at 'fuel economics' cost/mi which includes the cost of the car and maintenance such as this calc.
Assume the best of the best at 100 mpg, you save ~ $1000 annually on gas vs my 33 mpg ecobox doing 12,000mi/year.
After 10 years, I'd save on gas $10,000 if the price of gas were the same, but my gas car being $13,000 is ~ in cost to the Leaf, assuming maintenance is the same. If gas prices were to double to $8/gal, I'd break even in 5 years with a Leaf.
