Understanding Range


Jan 23, 2021
The wheel size, weight make a difference. The tires make a difference. The OE tires on the Long Range Model Y, both the 19" and the 20" are all-season tires; tire efficiency is good. The Michelin Pilot Sport 3 (if that is the tire, not the Pilot Sport A/S 3, then it is a performance summer tire for maximum grip but poor tread life and efficiency.

The tires have an EU label of C on fuel efficiancy. That's not SO bad. And temperature was around 10 degrees celsius (50F) yesterday. I think not so cold. Definitely not so hot. :)

Guessing temperature is playing into your range discrepancy as well?
- Early Fall in Midwest/Southern USA vs
- Dead of Winter in Northern Europe

But you are on 4 year old tech with a 4 year old battery which probably has more degradation than any Model Y currently on the road?
I believe Model 3 and Y are more efficient than S or X, i.e. they take less energy to go the same distance and not all of that is due to battery size (weight).

Battery degradation is not an issue here, I think.
As my consumption vs range values do match with a 90kw battery pack.
It's just the fact that avg consumption per km is too high. If it was the degradation, I would get less range with the same efficiency / consumption. Unless the car doesnt really measure the wh/km, but just extrapolates from the remaining battery power.
Then we would see a wrong and misdirecting faulty high consumption wh/km value.
