Can someone explain the IG body construction technology?

So the IG is a body on frame construction. But what I’m starting to see is that a lot of the body panels are welded to other parts? It almost seems like it’s a unibody on top of a chassis? For lack of a better explanation. For example, the rear quarter panel is welded to the roof? So if you ding a rear quarter panel, it’s not just taking off the panel and replacing a panel? Anybody have video of how they put together an Ineos‘s body? I was kind of surprised that the rear quarter panel doesn’t end at the belt line, it goes all the way from the bottom facia all the way to the roof.

It's generally how cars are made nowadays.

Go back to say the 50s most cars were made of individual panels which were bolted or spot welded together.

The downside of this process was that it was very labour intensive on the production line. Not just the fixings, getting panel gaps right and it being a 2 man job for each panel too. Land Rovers being a classic example.Also that method created rattles, squeaks and promoted corrosion.

It's far more robust to use a robot plant to weld together then dip and paint the body in one go.
Rivian are is a classic case here where even a minor dent can often mean a huge amount of work to replace large sections of the vehicle.
