Well, the internet says a lot....I would never get 295 miles out of my Model X 100D.I can't talk about 2017 MX 100D but internet says about 295ish while 2021 MY LR is about 320ish.
My ideal driving of my MY, I got around 300 in range
Well actually, there are tons of data which are saying different things. The ideal would be to find someone who has a 2017 Model X and a 2021 Model Y LR and who can tell me how they compare in terms of range with the same driving style...not sure what you were searching for, but there are a ton of threads efficiency. since you own an X, i would start in the Y forum and compare to your own data.
Hi all, EPA says 2020 Model Y gets 265 Wh/mi city, 296 Wh/mi highway, 279 Wh/mi combined. Also a range of 316 miles There's a solid line in the touchscreen energy consumption graph called "rated". What number is it? Also, Teslafi refers to "rated miles" which it uses to measure efficiency...teslamotorsclub.com
Thank you. That is an interesting and helpful answer! And absolutely, I wonder how much of an advantage and in which conditions it is that the Y has a heat pump!I don’t have a model Y, but I do have a model 3 and an X. I find that I get similar efficiency %, defined as actual range/rated range. So if I go on a 80 mile trip in my model X and use 100 rated miles (80% efficiency), I will do about the same in my model 3, also using 100 rated miles. Of course conditions can vary so I never have an exact comparison, but my Teslafi data shows that it is almost always within 5% of the same efficiency.
Advantage should go to a new model Y because it does not have any battery degradation at the start and for colder weather, it has a heat pump.
