They are conveniently vague, is that 90mpg starting out with a full battery and ending with a dead battery or running purely off the generator? know how the sales people of plug in hybrid kits like to market their product I would have to say that the 90mpg is ending with a dead battery and if so then how big is that battery and how much energy was used?
This is why I like solid numbers all around, I'm not trying to put down the hybrid idea but I like honest information.
