2016 to 2020 changes

[HyperionMark]

Other than the obvious MCU and drivetrain/battery changes, what else has been changed in 4 years on the Model X? I know there has been a few changes such as all X's now coming with tow package and maybe heated steering wheel, but I think there might have been ventilated seats in there as well. Any other small or big changes like that? What about design differences?

The design and functionality of the second row of seats changed. Also, the glossy black finish on the backs of the seats changed in March 2017.

There is another thread on here with those answers. Don't remember what is titled, but there are a lot of changes.

In the newer ones (not sure when it changed) the front seat headrests don't move up and down.

No more active rear spoiler (2016 only)
Front Seats changed in 2020
7 seaters -2017 second row are more of a bench seat vs. captain chairs
Ap2 in the end of 2016
2016 came with cooling seats option

That is from top of my head.

Synthetic leather vs synthetic alcantara.

Prior to 2017, Tesla was still using real leather before becoming vegan friendly. It was actually a separate option package - white seats were always synthetic.

From 2016-mid 2017:
Wood options were selectable in 2016. So you had varying combinations.
Premium audio.
Bio Filter

Those were some of the optioned specs. For the "hidden" or more subtle changes...

The 3rd row seats had a different armrest space in the 2016's vs the 2017's. In 2016 it was a flat padded area. In 2017 it was changed to be open.

The trunk shape was actually different with the 12v adapter being located on the side vs the back in 2016 vs 2017.

75D's went from 0-60 in 6.0s to 0-60 in 4.7s. (unless uncorked) in mid 2017.

2018 or 19 they changed the FWD/Wheel arch area of the frame. Small and probably unnoticeable but it's a flat space instead of a rounded space to prevent rubbing that a lot of people had issues with.

That change also seems to have increased the panel gap between the FWD and the rear glass. It makes the car (probably unnoticeable to most) more unsightly but allows more tolerance in the doors and prevents customer complaints and also probably helps with rubbing.

2020 got new seats
