Today after heavy rain I was wading in my Mini right on maximum depth 30cm. Navigating others who either had diesels or just went too fast. The dual carriageway was worse with some cars driving down the wrong side of the road to avoid deep water. Now here in Glasgow this is not uncommon on very bad days.

We all know about Tesla boat mode so please don't post these, hype aside what are the realistically cars can do. 30cm/1ft is really all I would need.

I can't see why an EV wouldn't be able to go to at least a foot, it's usually the air intake that kills IC cars in water.

Would be interesting to see what Tesla specify.

The issue here is hitting objects you can't see. What I have had is small stones get stuck in the brake callipers scoring the discs. So going slow is vital and avoiding a bow wave.

Point aside, my friend broke his Apple MacBook by trying a youtube fix with toothpaste and caused £500 worth of damage, a Tesla is more expensive and we know older ones can be easily broken with water.

The iPace has a wading depth of 500mm with the smallest wheels. Mine, with 22' rims and air suspension is about 600mm I would guess. The EV defender I'm told will exceed the ICE versions 900m wading depth! The scope for 'go anywhere' EV's is huge, we're going to see some insanely capable off roaders in the near future.

Not all manufacturers are so generous in terms of what they claim 'safe' wading depth for their EV's is of course, but I suspect pretty much all of them could do 300mm without major issues. The battery packs are sealed units as is the entire drivetrain including the motor(s).

Any EV that can't do it I would presume has missed a trick and has something like an air intake or unsealed electrical enclosure mounted low enough down to limit it's wading. Or just seriously crappy door seals smile

Yeah I am a mini driver and would assume most car can do a reasonable depth . For sure 500-600mm is fine for me and 900mm of the defender ott. I'm after relatively small EV thats fun around town but do the odd 150 mile trip, which would be stressful in the mini EV for example. I was hope for maybe a long range version of a Mini.

I’m always concerned with the undertray on the Tesla, which I’m told is made of cheese and assembled in two pieces which easily rip off in water, or so I’ve been told. Any truth? No idea.

It varies. My forthcoming iX which is huge can manage just 379mm, yet a relatively small Nissan Leaf can manage 700mm. Go figure.

That's really weird for the iX, I'm surprised. I know most owners have no intention of driving through more than a deep puddle, in fact most drivers these days would probably never dream of driving through anything more than half a foot of water unless they were used to doing so.. But still, the iX is supposed to at least pretend to have some off road ability so it's a bit poor if it has to admit defeat at a deep fjord and the Leaf coming the other way drives straight through!

I'm surprised this video hasn't made an appearance in this thread yet smile



An iPace goes through somewhat casually at exactly 5 minutes into the video.

I was of the view that overall tyre+rim size tends to be the same regardless actual wheel size. Would be interested of course to hear if there is a car where that doesn't apply.

Where does the 700mm figure come from? That's not far off a meter so I'm imagining it would be around the bottom of the windows on a Leaf?

It was a conscious design decision by Nissan based on the ability of the Leaf to provide emergency V2X power in a disaster.

Didn't the rear bumper used to let go (on early Model 3's)?

Either way I'd take it very slowly as the forces involved with displacing water at speed are huge!

I'm sure there are several such cars - I was told by Jag that the 18" rim plus tyre is smaller than the 19,20,21&22" rims in terms of overall diameter.

The rims and subsequent tyres are specified when the car is built so no problem to adjust the software for the correct wheel diameter.

For my comments above I added a guesstimated 20mm for the bigger wheels in addition to the air spring travel which is something like 70-80mm.

I used Kwik Fit to find the tyre sizes and then calculated on the 'Will They Fit' calculator. Looks as I thought... but like I said before... would like to know if things have changed from what I know as I like to learn.

They are a tyre family for the rough diameter of tyre on various wheel sizes. The larger wheels will tend to have a slightly larger loaded radius than smaller wheels. Maybe 10-15 mm extra.

Maybe that's why I was told the 18's were smaller radius..

Not that it matters, the air suspension is clearly the biggest addition to wading depth, that's why I mentioned it re 'standard' wading depth.
