We did a quick ~12 mile 70 mph efficiency test in our Model Y and our EQS SUV since the temperatures are dropping. We did the same stretch back to back. It was about 40 degrees with lots of wind. We did the same stretch back in the summer when the temps were 80 degree, here are those results
70 mph - 40ºF
I can't wait to repeat these tests at 20º and eventually 0º. I look forward to seeing how each perform real world when it comes time to doing a long drive in these temps as that can also tell a different story vs just doing a shorter efficiency test loop
70 mph - 40ºF
- Model Y = 297 wh/mi or 3.4 mi/kwh = total range of 252 miles
- EQS SUV = 413 wh/mi or 2.4 mi/kwh = total range of 262 miles
- Model Y = 269 wh/mi or 3.7 mi/kwh = total range of 269 miles
- EQS SUV = 340 wh/mi or 2.9 mi/kwh = total range of 318 miles

That's awesome. Does it have a heat pump?
We had a 32 degree day and the EQS is taking a hit already. ~16% reduction already whereas the Y is only seeing a ~6% hit. Our Y has a heat pump vs no heat pump in the EQS so it's to be expected. Even with poorer efficiency, the EQS still has more range overall since it just has more battery. I'm curious to see how each does as it gets colder. I'm curious if there will ever be a point where we see the Y ending up with more range. Maybe as it gets closer to zero degrees?
It does make me wonder how much better the '24 EQS SUV does in the winter. Over our 2023, it has a heat pump, a front motor disconnect, new battery chemistry, 10 more kwh (118kwh usable from 108kwh). I'm sure it would do a lot better than our 23.

I was actually going to post this on my Y thread, but now that you mentioned cold weather and efficiency, mornings have been in the 40's here, and I've had the heater set at 70 plus defroster in my Y, and efficiency hasn't changed. My 10 mile commute I'm only using about 2 kWh, same as when the temps were higher in the summer. The difference now is that you can hear the heat pump, which sounds kind of like a jet engine when it first starts up to heat the battery and cabin!
@Allen K 2018 Model 3 doesn't have the heat pump, thus why your efficiency drops in colder weather. My Polestar also doesn't have a heat pump, so it take a hit in colder weather as well. Heat pumps make a HUGE difference

I have a number of EV's on my list that I was planning to test drive and review (the next test drive and review planned is an Audi RS E-Tron GT), but I'm putting this on pause for now due to year end projects which will be taking up most of my time. I'll pick this up next year when my projects have been completed

BEVs comprise one in five new car sales in California through the end of Q3. Over 20% EV in a CA market which overall is up over 14% compared to the same first three quarters of 2022.
Including hybrids and fuel cells etc, the percentage of electrified vehicle sales through Q3 was over 35%

If the speed limit is 75mph do you travel 70mph or was that just for your research?

my buddy just drove 200-210 highway miles. The speed limit is 75mph. So he was traveling anywhere from 75mph-80mph and he couldn’t make the drive without stopping to charge in his MYLR.

It was just for our research. We went 70 in a 70. We never go under the speed limit, we usually just stick to the speed limit or at least not more than 5 over when on long road trips to get the best range and to relax and not worry about cops.
