    I went about 8 miles on the freeway to the store. On way home, went over 2 overpasses. After the 2nd overpass, I got 'er into stealth mode (all battery, no gas!) at 37 MPH. I caught 3 green lights and was able to maintain constant speed. My estimate is I went about 1 mile at 37 MPH on all battery. That was a nice boost to my evening.

    When I turned into the housing tract, I went really light on the pedal. Made it 1/4 mile, turned onto my street and into the garage, no gas.

    Pretty cool!

    Guess I'd be happy with a Tesla Roadster ... I prefer electric over gas. :D

    Oh, MFD at 49.4 MPG average and 300 miles into this tank. I've had a lot of short trips to the grocery store on this tank.

    I've been able to go about 1.5-2 miles in stealth (without EV). With a flat or slightly downhill grade it can be done. Congratulations!

    I ran out of gas on the freeway at 75 MPH with 9 green bars. The next off ramp was one of those that splits off the freeway and goes for another mile before coming to a 4 way light. I went about 2 miles in total on ev and pulled into the station with 4 bars left.

    I used to have a flat stretch with a bunch of curves that was 1.4 miles long that I could do all in EV/glide without any ICE interference. This was from a standing stop. Construction has eliminated the path now. Before the construction the stretch was 1.1 miles--the 1.4 was part of a bumpy detour in the interim stages. I was only using about two bars for the 1.1 mile variant.

    I'm confused... the tank on our car is 10 gallons right? if you get 300 miles, shouldn't you be averaging 30mpg?

    Sure, if the tank was dry right now (and filled completely with 10 gallons at the last fill). Cycledrum hasn't given any indication that the car is out of gas though. If there are still 5 gallons left in the tank right now, and during the last fill cycledrum only filled it to 9.5 gallons or so, then the average would be 66.67mpg. As it is, it sounds like cycle drum has used approximately 6.07 gallons of the current tank so far.

    You're going to make me go out to my car and check... aren't you? :p

    Yep, there are exactly 8 bars on a 2007 Prius. I suggest that you actually try counting them. :rolleyes:

    Just so we're not all talking apples and oranges...there are ten pips on the guess gauge, and 8 bars on the battery indicator. :rockon:

    This morning, MFD reading -

    52.0 MPG average (mixed urban city/highway)

    381 miles on tank with 2 pips remaining

    Not too shabby :)

    I was just indicating that 49.x MPG was after many miles of driving, not a fluke like 5 miles after a fillup (which not enough miles to be accurate IMO)

    I've never put in 10 gallons yet. The most pumped in ever was ~ 8.5 gallons (haven't gone down to blinking pip yet).

    My fillup after that tank was -

    7.822 gallons 87 octane
    383.1 miles

    for 48.97 MPG average (MFD was reading 50.x IIRC, so it's about 1 -2 MPG optimistic)
