Everyone seems to be considering just the front of the cars. What about the back of the cars and the exhaust outlet? If it is under the water height for any good length of time and there are not enough revs being applied to the engine you will get negative pressure in the exhaust system and that could lead to the engine having a drink.

I always thought that was a risk with the earlier 940s with the main fuel pump underneath the car. We were using one in the infamous 2007 floods and it coped admirably, so I guess Volvo/Bosch must have thought of that one and designed accordingly.

I never enter more than a few inches of water.

I saw that this winter. Here it almost never rains, so the drains get really clogged year long, so one day that it rained for what must have been 20 minutes max, one part of the road started flooding. It wasn't yet too high so I decided it was alright. But it got really scary when I noticed a manhole cover getting carried by the water besides the car. I missed the hole because there were no cars coming from the other direction so I drove in the middle where the level was lower.

You never know what's under the murky flood water. An open manhole, a big rock that was carried by current... Best to avoid. But then again. I have had that issue 1 single time in 2 years. Where it rains a lot must not be that easy.
