How deep is too deep for the Z?

ProfessorDave

Hi All,

We had flash flooding (again) here last night. I had to go through a fairly deep puddle (actually it was part of a creek that jumped it's banks). I could not avoid it - only way home. I would say it was 8-10" deep . Fortunately I made it through without incident, but I was holding my breath, worried mainly about hydrolock (note: if the meteorologists knew anything useful, they would have forecast this possibility instead of the "light showers" they predicted , and I would have been in the Mazda3 and not the Z!).

So it got me wondering, how deep is too deep? Obviously, I would prefer not to drive through any standing water, but wondered what is safe in terms of intake inlet height, ability to sustain traction, etc.
