Is my XLE 2023 MPG normal ?

    No, OP's EPA values are correct.

    For some reason, I thought the OP had an AWD version so my bad.

    After some more miles, I have better news about mileage in my 2023XLE. My wife and I had to go to a Funeral about 125 miles one way. I asked her to drive going to it and I would drive coming home at night. I reset the mileage just before the start of the trip. It was about 40 F to start and 45 F when we got there. The best I saw was 55.7 mpg and finished at about 55.4 mpg. We did not run the heater because the sun was bright and comfortable. When we left the funeral, it was about 4:30PM and temperature was about 40+F. The headlights came on before 5PM. Left the heat turned off. When we arrived back home, 54.4 mpg indicated. On both legs of the trip, cruise was used all the time possible. We drove through less than a dozen small towns with only a few full stops. I now think the heater, outside air temperature and maybe the lights have been my problem. My wife's great mileage of 68.2 in her 2023LE, on a trip to see the grandkids is not a fluke. She only got 60+ coming home. I will continue to log fuel purchases and miles to get a longer-term picture. I am not as unhappy as I was.

    Temperature, topography, technique, and speed.

    You will get the best MPG's in mild temps (no heat/ac), over longer trips, on flat roads, at moderate-low speeds.

    The big variable you can control is technique (ie. accel/decel, gliding/coasting, anticipation).

    I have a 2023 Prius LE purchase August 16th. Currently have about 2300 mile. I live in the North County in the Florida panhandle. About 120 miles were on the interstate driving between 70 and 80 mph just playing around to see how the car handled speed..(it is a delight)...the remaining time is mostly spent driving at 55 to 60 with the cruise control on..limited time spent in stop and go traffic. Temps have been running from hot and dry August through September with temps currently between mid 30's this morning, warming to 50's 60's range.
    Average mpg's since new 62.1.. I am a happy camper.. This is my second Prius.

    Here are two cent comments
    .
    1) Tire pressure can be a factor.
    Many bump up one or two psi, yet a pyrometer seems to be a foreign tool to many.
    Note a high-quality air pressure gauge can be an asset.
    A gauge that reads in 1/2 pound or 1/10 of a pound.
    2) Wheel alignment could also be a factor.
    Again a pyrometer in addition to one's eyesight can help with analysis.
    Note appears the car is new, but there are assembly tolerances.
    OP's warranty may cover alignments for the first year, otherwise, the hundred plus dollar alignment cost will offset any fuel savings cost.
    3) Winter fuel blends typically give lower mileage than summer blends.
    4) Yep, use of heater seems to affect mileage.
    5) And yep, you still need to use the "go pedal" for acceleration; on-ramp merging and lane changes.

    With that said...... check the tire pressure :)

    I would love to get those type of miles, I live in S. Florida so there is no mountains or hills :) . Even when I try to go easy on the pedal I still get crappy MPG average , This is not my first Prius, I had a 2010 14 years later I traded for the xle. 20240309_153423.jpg

    Turning on ECO mode, my MPG went up from high 40s to 50+ even in hot summer similar to Florida climate.
    It should add 2-3MPG the main difference is the AC doesn't blow as cold at first, if you can deal with that.
    The weather has a lot to do with it.

    "Most cars" means traditional gassers, not hybrids and EVs. After seeing previous Department of Energy figures on mpg vs speed, which I believe was tested before the hybrid era, I don't agree that the people making this "55 to 60 mph" claim are interpreting that DOE data correctly, it was for a different purpose. And from direct personal experience, I know quite well that Prius speeds in the low to mid 40s produce higher MPGs than 55-60.

    Previous Prius MPG vs Speed tests and mathematical modeling among enthusiasts here and in Japan, specifically on Gen3 and earlier Prius generations, have produced several answers for Prius Peak MPG:

    * under 25 mph, from a member here who tested and plotted MPG for speeds 25-80 mph. Unfortunately, the chart in his original post has been lost to repeated PriusChat host migrations (many broken links and lost images), though might still exist from being copied to other posts years later. Wayne Gerdes over at CleanMPG has similar charts, though I don't remember his testing below about 40 mph.

    * about 15 mph, according to one group of test-and-model fans;

    * between 10 and 20 mph, according to another group of test-and-model fans on the opposite side of the Pacific.

    Combined with the value of the driver's time, the Prius' "optimal driving speed for fuel efficiency" is "the lowest speed the driver can otherwise accept or tolerate, or ~15 mph, whichever is higher".
