Since I've had the ZS, I've had to slam the drivers door hard to close
it. I had assumed it was due to the fitment of the door. but then I
discovered that the door closes easily if the window is down, or even
down just a little bit, so then I concluded that the problem was due to
air pressure in the vehicle. but here's the weird thing, if I'm outside
the car and close the door from the outside, it closes easily, which
doesn't make any sense if the problem is air pressure in the vehicle. ??

It may sound stupid, but I've seen similar things and it's been due to
the way the door frame flexes when it's closed. Pushing the outside
handle makes the door shut differently than pulling it from the inside.
I'd also have a look at the top of the passenger's side door next time
you're in the car and shutting the driver's door. On some cars here is
enough force created by the closing of the driver's door to move the top
of the passenger's door open enough to see daylight through the gap :)

Take note if you are closing the door from the outside the same distance
and with the same velocity as you would from inside after getting in.
Depending on the distance and rate of the swing on the door may also be
a factor in the speed in which the air is displaced.

it won't close properly from inside unless I slam it. on the outside I
just close it normally.

Sounds like a load of old cobblers. Some decades ago, the design of car
doors changed. The older cars used to have a separate window A frame
which would flex easily. These days, and you can look at your own car to
see this, the door consists of an inner and an outer panel, both of
which go right from the bottom to the top of the door. They are much
stronger in the window surrounds because of this - hence the build up of
pressure internally when shutting the door.

Maybe on Darren's choice of vehicle. It takes quite a bit of force these
days to move the A frame on decent quality cars, even when you want to
move it.

What you would be better off doing would be to enter the vehicle, sit in
the seat and turn off the AC recirculate and onto fresh air. Then shut
the door. Try it with key on and key off - or with the fob present for
keyless start. While you're at it, try having someone else shut the door
from the outside while you're seated in the vehicle. And again when
you're not. Experiment a little.

The recirc. flap in the AC unit is the likely culprit. It's normal
behaviour courtesy of buying a car designed for Chinese city pollution
levels.

it's on fresh air by default

I think these days car design has to be a composite and compromise of
all it's markets requirements

There is also the leverage factor to take into account.

If you're like most people you shut the door on the outside with your
hand on the handle, in which case you are pushing the door at it's
furthest point from the hinge/pivot (or near enough to it) and are
employing the higher degree of mechanical leverage than you would be if
you were pulling the door closed on the inside using a handle that's
near the centre of the door.

Some cars are. Generally the cheaper the car the more the degree of
compromise.
