My 6-Year-Old Model X vs. Brand-New Model Y L — The Range Difference Is Incredible

I recently traded in my 6-year-old Model X. When fully charged, the Model X would show an estimated 330 miles of range — almost identical to my brand-new Model Y L, which shows about 332 miles when fully charged.

But the real-world difference on the same 200-mile drive to Durango was HUGE.

With my Model X, I had to keep my speed around 72 mph to make the trip comfortably. Even then, I would arrive with only about 15 miles of estimated range remaining.

I just made the exact same drive in my brand-new Model Y L. This time I was actually driving faster — averaging around 78 mph — and when I arrived, the car showed 125 miles of range remaining. I'm loving this new Tesla!!!

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.
