This looks like a stealth advertisement for their CT scanning business. There is nothing educational of value for the general public here. The only reason you would do this is for competitive analysis and I assure you the other car companies have already analyzed these parts.

Yes, that’s exactly what it is. On the other side of it though, so what, we get to look inside stuff with a cool scan. They’ve been doing these posts for several years now, and they’re all interesting.

The part where they highlight the rippling in the lithium battery was interesting. They mention it can accelerate degradation over time. It's unclear if this specific example is within tolerances, but I have seen in other CT scans how dramatic the lithium rippling can become. But overall, yeah, this is mostly an advertisement. They have other videos on their YouTube where they scan random items.

It's called content marketing, and there's nothing stealthy about it in particular.

There actually is a company who does this. full tear downs, of cars top to bottom. Interesting stuff https://www.jalopnik.com/the-fascinating-company-that-tears-cars-apart-to-find-o-1787205420/ https://www.jalopnik.com/the-fascinating-company-that-tears-...

I would say that there’s quite substantial value perhaps not to the general public but to the general HN user from their reports. I was very excited to see them have a public scan of an LFP battery because the previous scans they did of batteries were very informative on which brands to trust and the level of inconsistency that can exist. Their analysis of BYD’s battery design is very useful to someone who is looking to understand LFP and the levels of quality control necessary to have safe batteries. The reports are a bit of a “How it’s Made” but written for the target audience of engineers and has similar utility.
