    not yet, but I've only had my Prime since November 2016 and I've filled my tank several times since then, it's supposed to show up after 1 year of no gas fill ups

    ok, here's some solid info. drove off in HV mode with 32.5 miles EV. While driving around 70 MPH my EV would fluctuate from as low as 28.4 miles to a high of 31.2 miles. when I arrived in Ann Arbor I travelled 58 miles got 50.0 MPG and my EV was at 29.5 miles.

    What I would really like to see is the mpge if you ended the drive with 0 EV. Also, if you took another route and was able to lower the speed.

    Last month I drove a couple thousand miles from Chicago to an eclipse viewing spot in NW Nebraska. I charged up to 100% at home on my L2 right before I left for an estimated 33.x miles. I used regular HV mode (gas - arghhh!) for the entire trip there and back. At the end of day one, I had between 97% and 95% remaining. It fluctuates depending on temperatures outside and the temp's around the main battery. At the end of day two, and at 850 miles in HV, I was down to 92% - I still hadn't used EV mode. By day four it displayed 83% left. Still no intended EV usage. My conclusion is that there are losses both real as well as some phantom losses as the car seems to use the battery reserves in some way unknown to me.

    Before I returned home, and with about 80% charge remaining, I greedily stole some electrons from a nearby camping site's 120v outlet to get back to 100%. I did pay for the camping if you're wondering (but not for the site with electric :p ). This was the first time I used the L1 plug and cord that came with my car. That 20% took two friggin hours!

    [​IMG]
    Slow charging in Hemmingford, NE.

    The two day trip home, again completely in HV, this pattern repeated and I was down to a little below 90%. The phantom drain was still going on. The final 15 miles I happily shifted my driving style to pure EV and still had some small EV miles left on the readout when I pulled into my driveway -- where I then immediately plugged into the L2.

    I've noticed that Hv targets current charge level or 80%, whichever is less. I drove 400 miles starting at 80% and it stayed right there.

    L1 will give you 10% every half-hour up to about 98%, then the last 2% will take another 30-40 minutes.

    Charging is non-linear, so the final % is much slower. Using a remote outside outlet like that will slow it down even more.

    Correct, water penetration into the system is prevented.

    I certainly haven't ever encountered any trouble, going months between fill ups.

    Just before filling up the third tank. The only reason for filling up was to deliver a Gen-1 battery pack to Knoxville.

    Can you supply some details on your driving habits? I am assuming mpg's like this are due to a lot of EV and shorter trips. What kind of mileage did you get on the Knoxville trip? Have you tried any high speed/long trip techniques to increase mileage?

    I live in Huntsville AL and everything I want is within 10-15 miles. We are also well populated with free L2 chargers.

    I’ll have to check my records on the Knoxville trip but I am sure between 55-60 MPG. I use dynamic cruise control to follow a pacing truck or car:

    • 467.5 miles
    • 58.8 MPG

    It's not possible to save EV charge as loads continuously vary. However, if you want the best mpg, use all of your Ev, let the car switch over by itself and then observe the results. Shockingly rewarding. Note: I am speaking of reasonable driving. like Bob Wilson.

    And yet, I've done it several times over thousands of miles.

    My first tank was 1509 miles.
    My fifth tank was 1151 miles.
    My sixth tank was 2045 miles.
    My current tank is over 1800 miles.

    Ditto, I'm' on track to duplicate your results, I just need more time behind the wheel. Absolutely doable depending on where you live and drive.
