1973 New Yorker is rear-ended by Kia Forte

Could be. That was one of the ways to absorb small impacts.
However, damage on KIA is such that tells me that was not the case. Chrysler had to absorb some energy. Where that energy was absorbed is the question.
Key point. All, that highly engineered and controlled "beer can" crumpling dissipates a lot of energy as intended.

I think the New Yorker came out a bit too well to be realistic which no scratches on the trunk lid. But the frame is a lot of steel so it could flex within its elastic limit and come out the same. The KIA is designed to blow up the front end to absorb energy as well, so the peak loading on the New Yorker could be quite small relative to its simple heavy and relatively flexible frame. I assume these had a big arch over the rear axle? Also the body isn't attached super rigidly either to the frame, so it all might flex enough to not damage anything?
I know I'd rather be in the KIA more serious accident, but simple heavy 70's cars win for parking lot speed hits.

I think the big mopars back then were Unibody. Chrysler was an early adopter to unibody.

73 had unibody and most mopars from early 60s and on had unibody except for a few years of imperials
 
Chrysler started unibody construction in 1960, except for the Imperial cars. Imperials started having unibody construction in 1967.

Unlike the rest of the Chrysler Corporation makes (Chrysler, De Soto, Dodge, and Plymouth) that began unibody construction for 1960, the Imperial retained separate full perimeter frames for rigidity through the 1966 model year. These substantial frames had a box cross-section with strong crossmembers connecting the frame. The convertible had extra strength built into its crossmembers that formed an "X". The driveshaft passed through a hole in the "X" frame. The parking brake gripped the driveshaft and was not connected to the rear drum brakes prior to the 1963 model year.

My dad got rear ended, similar vintage Newport. Huge trunk was crushed practically to the back window. It was less than a mile from his house. He did drive it home. Unfortunately I lost the pictures of the wreck.
 
I've got no connection to this, I just read this forum, thought this was interesting as I also own a large Chrysler from this era. The bumpers in '73 (as if they were not strong enough) were strengthened even more with 1/4 inch stiffener plates probably to satisfy the 5 mph bumper requirements.

Love the bumper sticker.

Yeah, that is not how this is going to end up.
The Chrysler will have damage underneath, as there was nothing to absorb energy. KIA absorbed most of the energy, but still, Chrysler will have damage, potentially in critical spots. I have seen a KIA Soul against one of these 70's vehicles, in a frontal collision, and the end result was not pretty for the old vehicle. KIA looked smashed like this one, but the passenger compartment was intact. The old vehicle, on the other hand, had a roof completely messed up, as well as the driver's floor.
The driver of Chrysler was lucky he was rear-ended:


A '59 GM B-body was chosen for a reason, It has a X-Frame & the body structure was likely the weakest of all GM X-Framed vehicles. There is literally no protection in a overlap crash like that.
