What am I missing in the trunk?

Yup! Better than the Prime, which apparently has no tire, no strap, and no place to fasten the strap.

 

Yup

 

I was curious so I checked my storage and it looks very similar to Jerry’s picture, I have attached my own.

There is a strap which I have never used and presume it is the spare tie down strap, and the other compartment is empty. Granted I did buy the car used and it was missing a couple other accessories, it seems the consensus is nothing came in that space, as peculiar a shape as it is.

On a similar note (and sorry, don’t mean to hijack the thread, but it is somewhat relevant), I was skeptical about the usefulness of the narrow deep space behind the battery, but it is actually the perfect size for all the necessary tools I need to cart around. A spare jug of washer fluid fits perfect in the ‘bulge’ part, and around that I keep a DC electric air pump, traction aids, tire plug repair kit, a few random tools like screwdrivers, emergency toque, scarf and gloves (it is Canada where I am, eh!), and of course the charge cable which I tri-fold and it results in the perfect length to lay nicely across the top and the lid closes clean.

That space seems quite a bit smaller on the Prime...

 

Yes, that's what it is and I'm using it for that now.

I have a similar assortment in that space. Except that I keep the 120V EVSE coiled on the rear deck for quick access at work or church. I keep my 240V EVSE plugged in at home.

I finally got to see a Prime at a dealership. I agree with that assessment.

 

there's a tradeoff, but there was for the pip as well.

 

One end of the roll-up cargo cover stores here when you don't need it. Still, I have no idea what the other 2 shapes are for.

 

That seems plausible to me.

That cavity to the right always looks to me like a place to lay Aladdin's Lamp on its side.
