Dunno, but have you looked closely at the Mondy's air intake? Let me describe it.youve got the mouth bit, then the pipe goes down, and at the bottom of the curve is a hole!! Presumably to drain out any rain water picked up by the mouth. So picture this:You're driving thro' a flood and the bottom curve of the air intake, with its hole at the bottom, is under water. I think the best thing is to avoid the flood at all costs, 2ndly if you've got no option but to drive thro', then before you do, disconnect the pipe from your air filter box and for good measure remove the filter itself. I suppose your speed would depend on where you're driving... surely if its in a built up area with people and shops/houses it would be desirable to keep the bow wave to a minimum..
Not planning to drive through anything that is deeper the the tyre depth but just feel that when I see these idiots ploughing through the flood at some kind of speed, I feel that if they stall the car, they get what the deserve.
The only time I drove though anything that was deeper than I expected, the pressure of water flowing through the bottom of the grill, snapped off the undertray. I was not a happy bunny!

I first got interested in the sea tractor when I saw it in the film 'Catch us if you can' starring the Dave clark 5.
I cant find a youtube vid from the film showing the tractor, but this clip shows a nice snow scene. For info, my cat was born in the farm on the road shown at the 2 minute point of the video.
i was taught to keep the revs up to prevent too much going in the exhaust as it cooled, and slip the clutch to avoid going too fast for the 'bow wave' created at the front of the car. it got me through water that was deep enough to come in through the door seals on a mk3 Fiesta and was close to bumper height.
I'm always fascinated by those 'off road' whizz kids how have the air intake on a long stalk so that it is near the roof line. Particularly on Landrovers and some Discoveries.
If the air intake needs to be that high, then surely the entire vehicle would be floating?

the urpose of the high snorkel is more for entry into the water than whilst actually driving through it. yes there are times when the car might float (a mk3 Fiesta tries with water at bumper level until the car fills up!) but the water WILL get past the seals and into the cabin if its there for any length of time (which isnt really an issue in a real hose down land rover!) and stops you floating. also when dropping into a river from the bank, the intake can be at a level where it could suck water into the engine and not be particularly deep on the car, hence the need for the snorkels. plus, many think they just look cool.. it will soak the ignition on a petrol model usually before getting to the air intake at factory height on level ground, but on Diesels (especially pre 200/300tdi) then theres not that many electronics that affect anything so a diesel will run pretty much right up until theres no air or it cant expel the exhaust gases.

Excellent link and interesting read. I don't think he goes far enough; if you ignore the advice and blatantly enter a flood area and the car stalls, tough luck kiddo. We are too busy to rescue you.
Kinda of a DIY Darwin Award for you and your car.
We had a flooded Surrey country back road near me recently, I went to take some photos as the Parish Council are trying to get funding to improve (or unblock) the drains. Not life threatening, but I watched a lady walk into it to check the depth; near the top of her wellies. She and others went through no problem, I decided to back track, if for no other reason than I don't believe that any car is made to be totally waterproof on the underside. Plenty of holes in the sub-frame to allow air flow and hence drying out, but probably not designed to be filled with dirty water.
It is actually quite difficult to make a car sink, as they sometimes do in the movies. I worked in special effects and X years ago, we had to make the small jeep that plunges off a bridge in one of the first Jason Bourne films. As it hits the water, it just goes down.
We removed the engine and drilled holes everywhere to slow the water to flow in quickly. The stunt was done at a film studio. Car was fitted with a chain running through some big pulleys into the water tank, and attached to a tractor. Stunt man inside with breathing gear. The tractor basically pulled the jeep off the road, gravity took over and then the tractor just pulled it underwater, straight down as required for the 'special' effect.
I know they're not the best cars in the world, but i think Dave is a bit harsh saying this about them.
