Forever I keep hearing IT IS A BOX, your never get good MPG out of a box.
YET Chevy in 2019 made a full sized Express Van, long wheel base 3500 155" with a 4.30V6 Direct injected, 8 speed:
AND it is officially on the window sticker listed as its MPG of 19 City and 29 Highway.
It is a brick sitting high on its wheels and get 29 highway.
There is no real Aerodynamics on it.

Vans are/can be, aerodynamic in their own sort of way.
As a vehicle increases in size, it's volume increases faster than it's external area. Because of that you can haul more stuff or people with less aerodynamic drag per person or quantity of cargo.
Bigger vehicles also end up becoming longer in proportion to their height and width. That is also an aerodynamic improvement. For an example, trains are very aerodynamic because of their length.
Not that curves can't help. But a curvy vehicle body isn't everything.
