Prime XSE Battery Range???

Give it some time to adjust to your driving style. That’s why it’s affectionality referred to as the Guess-O-Meter.

 

that's a very sad help line for the manufacturer.
there's no such thing as range, only energy storage. how you drive the car, how much hvac, and environmental factors are what convert the energy into 'range'.
if you're impatient, start with a full battery and drive until the engine comes on. that will be the range for that drive.
the displayed range is just some combination of past performance as interpreted by toyota software.
if you do the same drive everyday, it will be pretty accurate after a time

 

1. If you have XSE the Mac range is supposed to be 39 not 44
2. I took delivery of my XSE premium last week and I’ve had the same issue of the range max showing 35 not 39
I called Toyota and they did not give me the same answer they gave you. They told me to take it in to the dealership service department and see what they tell me.
3. By the way, I have had an issue where I cannot get the multi information display to show the range as miles and not percentage. Does anyone know how to change that?

 

My '24 SE trim now shows 57 Miles on full battery. It has been climbing ever since we took delivery. Advertised at 44 miles without AC.
I am about to test that, by actually measuring the miles until the petrol engine starts after a fully-charge battery.
But I am a conservative driver -- won a Mobilgas safety-economy run in 1956.

 

Here are the detailed range figures for Toyota's PHEVs as recorded in the EPA's detailed test files for Model Year 2024. Note that their spreadsheet includes separate ratings for City vs Highway Range (columns FJ - FK), though the normal consumer-facing information is distilled down to just a single Combined Range figure (column FL), rounded to an integer. Keep this City vs Highway difference in mind when testing how many miles you can actually go.

FWIW, I also included the gasoline MPG figures. The publicly advertisable EPA ratings are in columns J-K-L, the raw dyno test figures before downward adjustments and rounding are in columns M-N-O.

 

You’ll notice op never came back.
He must have figured out the reality that batteries don’t contain range, they contain electrons.
Advertised range is simply an epa test, which your own driving may or may not be similar to.
Speed, acceleration, hvac use, topography, tyres pressure and other external factors will affect the readout on the dash, which is simply a calculation of past performance and current battery charge.
As Jim mentions above, you need to drive electric on a full charge and see how far you can go until the engine comes on.
That’s how the epa does it.
