My experience of 75D, during winter time of -10C, 35KM commute 1h, HVAC at 20C, I used up 15~20% one way, or 30~40% per day, charged to ~85% everyday.

You'll have no issue with SR+ under those conditions. Heck, in my gen 2 Chevy Volt I would have been able to make that commute 10 months of the year and that's with a battery 4x smaller than the SR+

Even in the winter?
Yes. Probably down to -40C. Although I don't have much data past -20C which is the realistic lows we can expect in the GTA.
Edit: definitely down to -20C if you can charge to 90% at home overnight. I'd probably have to run numbers for -40C to be sure but we don't hit that here...
Got it, that's helpful and reassuring. We're so worried about this because its a significant purchase and the whole goal is to get my mom a safe and enjoyable winter car. While $17.5k is alot more to get into an AWD, I also don't want to be worrying about trading the car in, in 2 years, etc.

For sure. The car is rated at 150 wh/km and has a ~60 kwh battery. Even if you average 450 wh/km on the 80 km round trip that would only use 36 kwh. That's more than enough to leave sentry mode running all day even.
Oh, and I think it's pretty much impossible to use an average of 450wh/km on a 40 km trip.
Maybe if you did many 5km trips and the car cooled down at each one you MIGHT get that high (my wife has a short commute so I see her numbers), but not for a longer drive.
Also, this is a super worst case scenario. Most days you would be readily doing the trip in around 20-25 kwh (in winter). In the summer you'll likely get that done in less than 13-14 kwh.
Is that 20-25 kwh round trip and does that account for the phantom loss of 13H of the car parked?
It's a 50kwh battery and usually charged to 90% so 45kwh. But still very safe amount of energy. Worst I did this year on 50km was 278wh/km at -16C in an hour and 20 minutes. Worst at 25km drive was 297wh/km at -12 in 47 minutes.
I think you would still be ok up to 400wh/km. Which I've never hit on a drive over 5km in length. On such short trips pcons is right that you'll spend a lot of energy warming up the cabin that'll be lost if you park again.
The worst phantom loss in cold is about 50km at worst but you recover most of that energy as the battery warms as you drive. (You get a snowflake icon and part of the battery shows up in blue instead of green).
According to Tesla 90% is the safe zone and the car will warn you if you regularly charge past that.
Anything lower is better obviously 80 is better than 90 and 70 is better than that. But running low is bad too. So you also want to keep above 10%. Basically closer to 50% is best but I wouldn't lose sleep over it.
Edit: 90% is also the default setting when you get the car.

The phantom loss would be worst case around 3 kwh. That's assuming leaving sentry mode on.

Its this funny reality of if the rebate didn't exist, we would stretch to make the AWD happen. Even dumber, I would stretch to make the P3D- happen since I'll get to drive the car once in a while. Its the rebate factor that's really messing with our heads.
Just curious is the NEMA 14-50 generally a dumb decision to have proceeded with if we end up with an AWD?
Is your mom good with a RWD commuter in the snow? That, to me, would be the biggest factor to consider. Range sounds like it will work out just fine.
Everyone we've spoken to has said the RWD is amazing in the snow with winter tires. Is that an exaggeration?
Part of her desire of the AWD beyond the range anxiety.. is the AWD.
