Undercarriage Battery Protection Details?

[RawwrBag]

I Googled for like an hour and can’t find the answer. What is the Model 3/Y battery pack undercarriage made of? You can find lots about the S (1/4” aluminum + titanium, etc.) but what about the 3/Y?

Asking because I scraped bottom on a rock on a Forest Service dirt road and I’m now wondering how close I was to destroying the car.

You are fine. You were no were near destroying the car. Seems to me, the marks are just the rocks cleaning out the dirty from the panel.

But if you are wondering, the panel is pretty thick:

There are metal skid plates available if you wanted to replace the plastic aero shield underneath the front part of car but it wouldn't cover the entire battery. Someone here on the forums was selling them last year when the MY came out.
