yeah, its definitely weaksauce as an 'electric' vehicle.
having said that i've got 88mpg lifetime. i think i've filled the tank 4 times since i took delivery of the car in late march. of course, i'm using it primarily for around-town; if i had to make long freeway trips i'm sure the average MPG would look a lot more like a regular prius. and as it turns out electricity costs so much here in northern cal that i'm not really saving any money. but together with the leaf we're almost completely off of gasoline and that's a great thing.
it *will* go up to 65mph on electric alone, but the point at which the gas motor kicks in is really dependent on how much torque you call for. around here there are some hills that i have to crawl up at 25mph to stay in electric mode
