    I've owned my new Prime Advanced for 17 days now, had to purchase in Maryland and drive it home to Raleigh, NC as no North Carolina dealers have any Primes and they seem to think it will be months before they do.
    Here are two examples of real-world energy use.
    Day 15, example of battery-only driving: Fully charged, set trip meter, began 27-mile errand-running trip in EV-only mode. Weather 50 degrees and cloudy, heated car to 70 degrees, had headlights on dim and used seat heater at first. City driving, speeds 30-45 while moving. Four startups, four legs of about 5, 5, 12, and 5 miles all centered on downtown Raleigh. Arrived home with car meter showing 1.5 estimated electric miles remaining so the electric-only range would have been about 28.5 miles.
    Day 17, mixed EV and hybrid-mode driving. Set trip meter, left home in EV-only mode. Weather 45 degrees, heater set to 70 degrees, used both seat heaters first 10 miles. Urban driving at beginning, end, and middle of day, 40 miles at 55 mph, 10 miles at 65 mpg. Five startups over 6 hours. Used EV-only mode for urban miles, HV mode for highway. Finished with 83 total miles, tripmeter said 84.6 mpg. Ran out of battery energy one mile from home. Drove 24 miles in EV-only mode, 59 in hybrid mode. This implies use of 1.02 gallons of gas for 58 mpg in hybrid mode and zero gallons of gas during the 24 miles in EV mode. Believe this style of mixing EV and HV driving is what Toyota had in mind for this car design.

    What I did to check actual mpg was once battery was drained and was in HV mode, Reset trip and on trip screen it will show your accumulating mpg. I did a 100+ mile round trip at 55-60mph and averaged in the mid 60's. then did a freeway trip to Dayton at 75-80 and got mid 50's for mpg and when I arrived in dayton and still in HV mode I reset trip again while driving around the city and averaged 70mpg :D I was real easy on the gas and did the pulse and glide thing. id say 60 would be easy without too much effort.

    HIGHWAY

    From North Kingstown RI, I drove ~100 miles to brother Dave's home in Hamden CT. In automatic mode, EV was soon exhausted. Upon leaving Dave's home, I set the destination to Wilkes-Barre PA to intersect I-81. I topped off the gas tank and started clocking miles using dynamic cruise control.

    Upon reaching the Wilkes-Barre area, I took a lunch break and reset the destination to our home in Huntsville AL. The rest was use dynamic cruise control to follow trucks or other traffic with occasional biology breaks.

    Near Lexington VA, the "out of gas" warning light came on. The MPG was running about 55 MPG so I took a chance that there was at least 1 gallon of gas remaining and continued to the Daleville VA exit. I topped off the tank with 10.9 gallons. Subsequent testing revealed I had about 0.4-0.5 gallons remaining. At the Alabama border I took another coffee break and reset a trip meter to finish driving at 55 mph to Huntsville.

    Summary: 1,200 miles, 21 hours, 55.7 MPG

    HUNTSVILLE


    This week I'm driving all EV. In the morning, I switch the J1772 from the Prime to the BMW i3-REx and with a full charge, I drive to the cross-town road, the Parkway. Once I reach any area posted 25 mph or more, I set the cruise control including the neighborhood. The rest of the drive is 'keeping up with traffic' which typically ranges from +5 to +10 mph over the posted speeds.

    On cold mornings, I use the heated seat and drive in my medium winter coat. I'll hit the defrosters as needed to keep the windshield and rear glass clear. Otherwise the cabin heat is off and set the air valve to cabin recirculate. I drive using the cool side of comfortable with dynamic cruise control at every opportunity including coming to a complete stop at traffic lights behind the leading vehicle.

    At lunch time, I drive to L2 chargers near work and an hour later, the morning commute miles are recharged. Then I drive back to work slowly to preserve charge.

    When leaving work, I call home to coordinate any errands. Based on that call, I'll stop at shopping centers along the way with L2 chargers. When I get home, I switch the J1772 back to the Prime and unload anything bought on the way home.

    After six days, I'm at 244 miles and the experiment ends Monday morning. There is a good chance the experiment will end just under 300 miles for the week or about 15.6k miles per year. Add a couple of cross-country family and vacation trips and we're in the 18-20k miles per year we normally clock up.

    EPA city all-electric range is 27.1 miles, so you have outperformed EPA(y)
