I think folks should be warned about how this stuff is reported. Had a friend recently run out of gas on non-clarity phev because the car showed about 40mi of range, then went to zero and died. So why can this happen? The car is rated for 40-44Mpg. Seeing range of 40 miles may sound like something (or a lot) but you wouldn't keep driving your conventional gas powered car on one gallon of gas. So I coached my wife early on if the gas gets down to like 3 bars or total range 80 miles, that's like the normal warning time-- orange light, on a normal car. It means you maybe have 2 gallons of gas. Also, bear in mind that tanks are subject to ups and downs in the road. if you're on a non-level surface with like 1 gallon of gas, are you sure you can use it? In full disclosure I've never run out of gas in our clarity, but I also don't keep driving on a long trip when the gas bars go too low. For me, 80 miles of range left is 'warning mode' -Dan PS: I admit, PHEV users have another 'tank' for electric battery. So if your electric range is 30 and your gas range is 40 (total 70 miles), I'd grant you likely have at least the 30 mile electric range regardless of which direction your car happens to be tilting.
