same thing with the all electric cars. they flopped here in California. Nice but only a fringe market. Dont get me wrong, I love these technologies. But they wont have enough market share to make a difference in energy consumption for a very long time. gas cars that can get 60+ mpg are here now and have the potential to make a difference. Until some sort of miracle breakthru in electric storage technology (batteries) happens, some version of hybrid will rule the ultra efficient auto market.
CalCar is doing some interesting things to the new Prius. Up to 180 mpg at 50 to 60 mile ranges, then normal 50+ mpg after that.
