    It doesn't surprise me. My photo shows the mpg at approximately the "75" mark.
    Is there a better way to gauge mpgs at certain sustained conditions using stock instrumentation?

    Cruise control and tripometer. Reset it once you are at a specific speed. Just pay attention to what the wind and elevation are doing though.

    Why would you need to reset the tripometer? Thanks.

    I can do that too. Simply get up to 70mph and back off on the accelerator a little while the speed reduces to 66mph. However, can you do that as an average mpg for 10, 20, 30 miles on flat (effectively no net elevation change) highway?

    Same experience here. Also the overall speed vs. mpg charts you link are similar what I get; progressive worse mpg after 60 mph.

    I will try some more experiments this week on my way to work. I did the same drive with two of us in the car Saturday night. Full charge on the way up, did not charge in town, return trip was all HV and ended up at home with trip mpg at 60 mpg.

    So what I think really gave me the MPG boost was the slow Friday afternoon freeway traffic ~25-30 mph in carpool lane which allowed P&G and EV. I also live near the beach with an elevation of 11 ft above sea level, so it's a gradual decline all the way home. But as per Airstream's image -- that is exactly the MPGs that I am seeing on flat freeway at 65 mph.

    The problem with my commute to work is that I teach at a school on the side of a big hill ~1700 ft above sea level, so it really does a number on MPGs heading up. Return trip is great because I get 20 miles of EV and the last 10 are HV.
