Any chance this is related to the age of the batteries? Did you ever run the full set of battery tests on your model X?

When my X was new I never arrived in Durango with nearly this much in reserves.. These batteries in the new Tesla's are way better.. But i will say the degradation in my old X was very minimal. 6 years in and they only lost about 10%.

You don't say what year your model X is. Late 2020 refresh gets you the heat pump which makes a difference. Also, the Mode Y simply uses less energy to cover the same miles, so its rated-range number falls more slowly. Y is lighter, more efficent and more aero dynamic. Faster highway traveling will demonstrate those differences as they did for you.

My old car was a 2020 Model X.. I believe I purchased in late October. Not sure about the heat pump.
