Re: I'm finding the HSI gage very helpful dad's back from florida, so i got to take him to lunch today. i did 80 miles and the display shows 87 mpg. but i think that includes 9 miles of ev battery usage. so i'm not sure if the electricity is included or how they would include it. i think i'm confusing myself, but i did feel like i was getting a bit of a handle on ev driving. one problem i had was that, i developed such a light touch on the pedal in my gen II, i find it difficult to push down hard enough in eco to make the car go!
