What kind of Wh/mi are you guys getting?

Gotcha...I've heard the same and probably the right way to do the math...but i don't see me driving the car when it registers 0%...so i guess we are talking "effective" range vs "max anxiety" range, LOL.

Elevation, wind and speed are the factors to consider for highway driving. Drag on the car goes up dramatically beyond 70 mph. Starts to climb at 60.
It’s possible that the Y is different from all the other Teslas, but I think it highly unlikely.
Range, including the 0 point, is set based on a math model of the battery state of charge, because for a lot of the range the voltage doesn’t change with state of charge and voltage does change second by second depending on how much power you are pulling from the battery or pumping in.
The car shuts down based on the lowest cell group hitting a minimum safe voltage.
Not surprisingly, these two different measures don’t always align. Tesla sets the math model slightly conservative because of that.
But there is no consistent, designed in range below 0 miles, and for every person that goes another ten or fifteen miles beyond, there’s a person that was shutdown right at 0.
There are even cases, especially in higher load usage like towing in winter, where the car will shut down with a few miles left on the estimate.
Don’t count on having anything below zero. You might, or you might not.
The EPA rated range is based on the EPA driving cycle. Almost no one actually drives that. So Most of us switch the display to battery % charge and leave it. On a long trip (multiple superchargers) use nav and follow the instructions on the screen as far as stopping at superchargers and especially slowing down if needed. You'll be fine.
Main impact on range is tire type and pressure then speed. Here in Tx we have some 75 and 80 mph speed limits. My Model 3 (without the summer tires) can go only about 200 mi at those speeds before I need to charge.

Yeah. I actually leave mine on miles, but you’re right that the only number I ever really care about is the estimated percentage at next charge location.
I wish that Tesla gave us options to make that more prominent, and I’d love to have a comparison on the energy screen between what I’m actually using and what the profile they generated that arrival number from expects me to be using, so I can see how I’m doing in real time.

Isn't that what you get on the energy consumption chart? On a trip I keep that up and it shows whether I'm doing better (above the estimate line) or worse (below the estimate line) and what I'll have left when I arrive.
At a macro level, sure. But that still takes many minutes to show any deviation and is hard to read because it's squeezing a couple hundred miles of data onto the screen.
I'd like to see it projected with the 5/15/30 mile energy graph, or added to the real time power usage bar, or both. That'd be especially useful if I end up having to slow down to make a comfortable leg - you'd know immediately if you'd slowed enough or needed to do more.

Friend got a new TMY this afternoon, and supercharged to full. Should it show 310 like my TM3 does? I thought the Model Y got 315 for range (at least when new).
This is what we've got so far, 305Wh/mi. It's weird seeing such a difference from the SR+ that I drive vs her Model Y (AWD LR). She's been doing mostly highway driving here in Las Vegas where it's been about 100*F+ since we took delivery on 4 June. Most of that highway driving is above the 65mph speed limit...you'll get run over here in Vegas if you do 65 so we mostly drive about 75mph+
I think with the heat, mostly highway and higher speeds it's not too bad for an AWD on Gemini's. I do need to get all the tire psi's corrected but "cold" here has been like 75*F at 5am. I had to delete the token for TeslaFi because sleep settings just weren't working properly even though they mirrored my Model 3. Also, we've been having weird losses while plugged in on it's own 240V at home...

I had to disable my TeslaFi, it was draining over a mile per hour of range..
Do you have your sleep settings set properly? I don’t believe it should be draining that much range…

I’ve averaged 294 over 700 miles. Mostly small trips around town, one 350 freeway trip. Not babying it and enjoying the extra acceleration getting on the freeway with AC on.
I guess I should’ve been more clear, our Y is garage parked and then it bakes in there with all the heat. I would have to either leave it out all night or get it out first thing in the morning to cool off to ambient. I went to the garage this morning to set tire pressure and they’re at 41 but it was 80*F in the garage and outside it was 68*F.
