Looks like a bigger, 4-dr VW XL1

Agreed. It certainly doesn't have the overall shape of a DS, which is more of a 1930s tail-dragger.

The biggest aerodynamic difference that I can see is, the Lightyear One doesn't have a narrower rear track.

It'd even got the 'Hofmeister kink'.

Is that hole in the front for tradition, or does it need ram air cooling?

My guess would be that's where the evaporator/condenser for the heat pump/AC system lives. And probably a small water cooler for batteries/motor. |

I think the intake grill is for A/C mostly, and other cooling, and fresh air supply. It probably has a thermally controlled damper.
But the four motors are in the wheel hubs, and they are super efficient. The motors that were used on the STELLA solar race car were close to 99% efficient. So, not much heat coming from those.

The Lightyear One is nice, but look at the box it came in. It's got a bullet nose and radiused top edges, but when you get to the back there is a square door with a fillet to give a vortex generator/spoiler effect.
I'd like to see some tuft testing on that.

I agree, good observations.

Interesting indeed, kind of looks like Thule roof top cargo box enlarged.
My guess is that it allows for maximum rear roll up door and a bit of styling and not based on actual aerodynamic needs. I mean why would a balanced trailer need tail down-force at speed? That's going to cause lift on the hitch on the other end and unbalance the load.
I'm posting this video here, looks to have some aero-content.
