The Pru is just a design for now, not even in the prototype stage, though a representative says it could be ready in the first half of 2011. It might be sort of prohibitively priced, at around $15,000. Hopefully they can find a way to bring costs down, via government subsidies or whatnot. It enables a driver to actually use a short-range electric car as a main vehicle, even allowing weekend trips. It's definitely an interim solution, until battery efficiency and EV infrastructure is up to snuff in the States, but man, what a smart little interim solution it is.
