Submerge a Honda Civic or a Kia Soul in water, and you have got a soaking moist one-and-a-half-ton brick in your arms. Perhaps, with limitless cash and sources, you may salvage a flooded or hurricane-damaged automobile and hold it working for years to come back, however auto Youtuber Tavarish could not save his flooded McLaren P1 with a seven-figure funds and an extended record of business contacts, so it is not likely well worth the effort.
Electrical autos are, apparently, a completely completely different story. One would count on {that a} typical EV would wrestle to function after even minimal publicity to water, simply as a toaster oven or an HDTV would go on the fritz in the event you left it out within the rain, however, because the aftermath of Hurricane Helene has proven us, that is apparently not all the time the case, as one Rivian proprietor’s R1T appears to have survived complete immersion.
How Does Flooding Destroy Inner Combustion Automobiles?
There’s actually no a part of your automobile that you just need to expose to extreme water. Flood harm spells bother for each part of your automobile from the engine to the inside to {the electrical} parts. Hydrolock, for example, happens when the cylinders are flooded. Water would not compress, so that you wind up with bent rods because the engine tries to push the cylinders, and so they refuse to maneuver.
Should you can by some means spare the engine from hydrolock and drain the flood water, you must do not forget that flood water is not simply water. It is salt, sand, and particles. So you want to flush your engine and ensure it is utterly dry after which simply hope that no corrosion units in. And the mould odor by no means goes away. As quickly as a automobile has sat in flood water for a bit, it may odor like a bathe in an deserted roadside motel till you are able to take it to the scrapyard.
Regardless of the precise harm that happens after a flood hits your automobile, the underside line is that insurance coverage corporations will not cowl it. If you cannot insure it, then you possibly can’t legally drive it. This is the reason you want to be looking out for “title-washing” after a hurricane, the place a flooded automobile is taken out of state and given a clear title to promote with out disclosing the harm to the brand new proprietor.

With a lot harm from Hurricane Helene, individuals might be attempting to recoup losses by promoting off broken vehicles. Do you have to make the leap?
Are Electrical Autos Waterproof?
This is the actually cool factor concerning the Rivian R1T: the battery packs are constructed to be successfully waterproof. That is an enormous a part of what makes them so superior in the case of off-roading. You want a variety of floor clearance to really feel assured crossing a creek in a gas-powered Jeep Wrangler or Ford Maverick, however this electrical off-roader can tackle just a little little bit of water with out junking the entire powertrain.

That Rivian R1T that bought swept up in floodwaters from Hurricane Helene in North Carolina wasn’t simply splashed. It was washed out 150 toes from the place it was parked, and it was utterly caked in mud when the proprietor managed to search out it, just for the truck’s computerized pop-out handles to interact as he approached his automobile. On the time of writing, this solely occurred a couple of weeks in the past. If there are any long-term damages associated to the R1T’s misadventure, we cannot know for some time. However, by all stories, the R1T is at the moment functioning as if nothing ever occurred, and the inside is claimed to be “spotless,” and the truck nonetheless expenses simply advantageous.

Does that imply EVs are waterproof? Properly, that is perhaps a stretch. Rivian places their battery seals by means of the ringer, even blasting them with salt spray to check for corrosion, however there’s nonetheless a variety of wiring and steel that is being uncovered to the weather, and Hurricane Ian noticed 21 EVs catching hearth after their batteries have been submerged in saltwater again in 2022. This quantity turned out to be a lot decrease than anticipated, however the threat continues to be there. There is a motive why EVs which might be designed to drift in case of emergencies can solely accomplish that for restricted intervals.

Is It Protected To Drive A Flooded EV?
Rivian claims that its batteries are properly protected and “unlikely to pose a fireplace threat” even after being submerged in water. But it surely’s not simply the battery you want to fear about. Your predominant concern after an EV has been hit with flood water goes to be the potential for a brief circuit, however there’s additionally corrosion, mould, and broken wiring to consider.
The very fact is that we’re nonetheless in uncharted territory right here. We do not have that many flooded Rivians to level to for instance of what to anticipate after your R1T or R1S has taken a shower, however in the event you watch Chillin’ with Chet on YouTube, chances are you’ll keep in mind the experiment he ran the place he drove a Tesla Mannequin S Plaid underwater, and it was nonetheless working years down the road… however not with out challenge. Operating a monitor take a look at a 12 months later, Chet found points with the water-damaged motors, water within the oil system, and brakes that wound up utterly shot, ultimately leading to a fairly scary accident when the brakes failed at 170 mph.
To be utterly truthful, Chet’s Tesla was completely submerged. The flooded Rivian took just a little boat trip, nevertheless it wasn’t precisely going scuba diving. Even so, the very fact stays that water harm introduces an unknown issue. An electrical automobile that is working simply advantageous the day after a flood may not be in such nice form a 12 months or two down the road. Should you’re undecided precisely how intensive the water harm is after a pure catastrophe, you is perhaps higher off claiming the insurance coverage payout than sweating bullets each time your automobile appears to be malfunctioning. You probably have complete insurance coverage, chances are high you are coated in opposition to a complete loss because of flooding.
In any occasion, the important thing takeaway right here could also be much less that an electrical automobile can presumably survive a flood, and extra that it is safer to take it by means of deep water, mud, snow, and ice than you’d suppose. In different phrases, it is precisely what we have been saying for some time now, that battery energy represents the way forward for the journey automobile.
We are saying that figuring out full properly that EVs nonetheless have limitations in the case of off-roading. As an example, whereas Audi’s RS e-tron lately gained the Dakar Rally, it solely managed to take action with assist from a 2.0-liter turbocharged four-cylinder appearing as a generator. Vary is enhancing on daily basis, however vary nervousness continues to be sufficient to maintain most of us from eager to take an electrical automobile two hours into the closest nationwide forest with no backup plan for getting it house.
All the identical, anybody who says that these autos aren’t rugged sufficient to overcome any terrain you care to discover, properly, they have not been maintaining with the information.
