    I just had the first EV driving with my brand-new 2021 Limited. It broke the record of having the worst miles per SOC.

    Why is this so? The car is a fresh arrival—manufactured in October.

    Possibilities:
    • Battery needs to be conditioned by a few cycles before it reaches its maximum capacity.
    • Toyota has changed the battery vendor.
    • Dunlop tires are not as efficient as Toyo tires.
    • Limited advanced systems drain power.
    • 12 V battery needs charging, which is draining power.
    • Toyota has updated the hybrid system. In fact the new car sounds entirely different than the old one when it idles. I hear a strange sound when it first starts and I don't seem to hear the usual tone every ten second as with the old one.
    Perhaps the range will increase after a few cycles.

    Tyres also need to be broken in?

    Isn't it getting colder even where you live? What exactly was the EV range for your new 2021 PP and what was for the 2020 PP? A few miles difference may not be statistically significant. Try more sampling and compare the average between two models with standard divination.

    Yes, in the hot weather in the summer, I could get almost 40 miles per 100% SOC on occasion. With colder weather it has dropped down to around 31 miles. Last night it wasn't any colder than last week, and I got around 28 miles.

    I think it's partly the 12 V battery that is still charging, partly the fog lights that I kept on, and partly the battery that needs to be conditioned by cycling a few times. More data points are certainly needed.

    Nevertheless, my 2020 battery apparently didn't degrade at all after 7,000 miles. Perhaps charging the battery immediately to 100% and keeping it charged wasn't as detrimental as some have said.

    On a separate note, I love the Blue Magnetism color. The Classic Silver Metallic color was kind of cold, boring, and uninspiring.

    isn't the epa estimate 25 miles?

    Yeah, but we typically get 35 miles.

    It wasn't the fog lights.

    I think it may be the battery calibration. Hopefully the battery will self-calibrate after a while.

    Today during warmer weather, mediocre range (~ 25 miles) continued. I was scratching my head as the battery percentage was changing every ~ 0.2 miles as opposed to ~ 0.3–0.5 miles on my 2020 XLE.

    The car does sound totally different though. I get this light grinding-like sound at times, like at idling and in reverse, which starts and then stops and then starts again, which I never heard in my 2020. Also, the 2020 made strange musical tones—kind of like you hear during door closing on subways—that I've never heard on the 2021. It looks like they've made changes to the hybrid system.

    Hopefully the EV range improves because currently I'm getting more than 25% decrease in range in comparison to the 2020.

    could a brake be dragging?

    Stuff like that would defeat the purpose of buying a new car. LOL

    The noise also happens at rest.

    can you record the sound?

    Hmm, I wonder if it is the new artificial sound for safety. I also wonder what happened to the musical tone.

    With regard to the EV range, I'm hoping it will get better after a few battery cycles.
