Ok, this is something I rabbit holed on. If you want effecient space usage, you really can’t beat the Tesla model Y. Especially if you can get a low mileage used one, but be sure to avoid the 7 seat variant.
It has soooo much usable space. I took pictures to give an idea of how it’s different than a Ford escape hybrid, which was the other car I was looking at. Side note, hybrids are terrible for space efficiency.
The under floor section, generally where a gas tank would go
Second underfloor section. In a hybrid this is usually where the battery might be.
On top of the tote and toiletries bags/charger three weekend suit cases and assorted crap. Notice how much space is still left there are also two pockets, one on each corner.
Same area, just without stuff.
This would be the front trunk, or where the engine is in a gas car. That’s a normal sized ice chest and some random food to the side.
Hard to take a picture of, but there is no drive line or transmission tunnel either, so even more interior space.
Hope this helps visually how space efficient it is.
Edit:
I bought one in 2022 and am averaging about $20/month in charging costs.
Don’t get me wrong, I always wanted one of these, had an f150 back in the day, but these days 420hp isn’t even entry level for a lot of basic cars.
