seeing the seats attached to battery pack and then the crash points to drive the battery down and away in a frontal crash makes me go, hummm. Just hummm.

Watch the video again. At 2:30, it seems pretty clear that the seats are mounted to a separate structure that is attached to the sides of the body by the door sills.

Fantastic. I love these engineering deep dives, especially when they translate well to the laymen.

For sure. the pack adds structure and rigidity, the point of the pack being deflected downward in certain cases, was to protect the packs structure from being overwhelmed and cells being ruptured, but also to deflect some of that energy downward.

Great video! In the drive train section I wish they would show the original motor as well as the newer generation R2 to compare and contrast.. I'm curious is the battery pack liquid cooled? Is thermal management air or water? Just curious if anyone knows...

Understood. I was responding to the post that insinuated that the seats would also be directed down and out of the vehicle in the event of a crash. It actually looks like that post has been deleted.

They mentioned it in passing, the pack is glycol cooled.

I hope there will be an other video showing the internal of the battery pack and the transmission module. So far it was half an hour video talking in front of a full assembled battery.

I missed the Sandy Munro type of video showing details of the components and explaining the difference between, for example, the Tesla and the Rivian implementations.

In the main tear down videos, they would actually purchase a vehicle, test the vehicle as a whole, then tear it down to its nuts and bolts. They may still do that, but it's definitely costly.

Some of their videos on their channel of late involve "donated" components by the respective manufacturers, a BYD drive unit, or a Rivian Enduro motor as examples. The Gen 1 Quad R1T they ripped apart years ago, was one of two Sandy had purchased.

It's a similar cooling strategy to Teslas this time around, instead of 2 layers of batteries, with a cooling plate between carrying I believe a proprietary solution on the R1 (ethylene glycol) they went with a single battery layer, and ribbon style cooling loops along the sides of the cells in R2.

Given the fast charging demands of today's batteries, I don't think any vehicles at this point are air cooled, save for early 2010's EV's

Interesting video! Sandy doesn't appear in this episode which is an added bonus.
