- As the adoption of electric vehicles (EVs) gains momentum, our unwavering commitment to safety grows in parallel. Roadway departures, responsible for approximately one-half of all roadway fatalities, demand our attention. But what happens when EVs encounter traditional guardrails?
Guardrails have undergone rigorous testing over the years, yet the technology needs to evolve as the vehicle fleet changes. Recently, Texas A&M Transportation Institute (TTI) and industry leaders convened for a groundbreaking crash test. In this test, our researchers subjected a Tesla Model 3 to a 62-mph impact at a 25-degree angle with a thrie beam guardrail system-the same conditions used for MASH crash testing. The impact ruptured the thrie beam rail and allowed the test vehicle to penetrate through the barrier. This result shows more research is needed to help us better understand and prepare for the growth of more EVs on our roadways.
As we navigate this dynamic landscape, TTI’s research positions Texas at the forefront of safety innovation.
Looks like the guardrail failed the test.
Looks like your critical thinking failed the test.
That barrier totally failed.
I'm more worried about all the 3 ton trucks, not the 2 ton EVs.
You should be when they hit your non ev car it will fold like an aluminum can
@@lilpeppa117G Stop acting like the problem is EVs, there are lots of cars much heavier than a model 3. They need to build stronger barriers.
We replaced a Lexus is250 with a model 3. Both cars weigh the same.
And this car doesn't even weigh 2 tons...
@swecreations 3,862 to 4,054 lbs, depending on trim for the Model 3
EV:
Tesla Model 3: 1.8 Tons
Non EV:
BMW M3: 1.8 Tons
BMW M5: 2.4 Tons
Audi A4: 1.7 Tons
Audi A5: 1.9 Tons.
My car Daihatsu under 1 ton 🗿
@@GF-mf7ml Wuling Mini, a bt larger than your Daihatsu: 650 kg.
@@GF-mf7mlI am more worried for your health now.
Show us an F150 pickup doing the same thing.
The F-150 will be redirected because the center of gravity is higher and will strike the rail instead of the center of gravity being under the rail and rupturing it. Therein lies the issue right now with EV's and the current design for guardrails.

I call BS. I have several family members who are in law enforcement and ems. Cars & trucks go through those rails all the time. In fact, I went through one myself a few year back.
@@mast3397 do a little research Mast. Yes, guardrails do get pierced. When they are installed incorrectly or repaired with the wrong parts, or hit at high rates of speed. Those are all circumstances beyond crash test limits like this case here.
@@staceycameron7561 that's BS. center of gravity has nothing to do with this.
Ehrm ... that is a Model Y, not a Model 3, no?
Other than that, this vehicle is not *that* heavy, so probably this guard rail is simply not strong enough for bigger SUVs and Trucks at this speed.
Thus, it is not clear how this test specifically relates to electric vehicles or what problem it is trying to point out?
But the Tesla seemingly did great in terms of passenger safety.
A model 3 RWD standard range only weights in at 3600lbs. A Long range AWD model 3 weights in at 4000lbs. This is well within all 4 door ICE passenger car weights. The guardrail itself failed.
This is why in many EU countries highway guardrails are double, and some times triple, i.e. protection at several height levels.
Due to the EU tests and national technical norms
i don’t get it. what’s the issue? a Dual Motor Model 3 with no people or cargo in it weighs exactly the same as my 2011 V6 Tacoma Double Cab Long Bed with me in the driver seat. me driving my 13 year old truck into that rail will do exactly as this Model 3 did in the video. and i’ve towed and hauled things with my truck that a Model 3 would never. are we fat shaming EVs now rather than innovating better road safety technology?
A sedan should weigh as much as a full-sized pickup? Are you listening to yourself compare apples and oranges?
My Volvo (not an EV) weighs even more. Imagine what happens...
It's not directly a matter of weight, but where that weight is located. The weight on an EV is lower towards the ground than on trucks and cars. With your Volvo, the weight is higher up and the guard rails are designed to redirect that weight at that height. EVs with their weight being on the bottom towards the battery essentially goes under the guardrail and can't be properly redirected.
@@itsthecaptain17 So in plain language what exactly does that mean, is that a good thing or a bad thing?
@@theodorehaskins3756 For a normal car, it's fine. For an EV, it's bad.
EVs essentially go under the part of guardrails that actually stop or redirect cars.
Normal cars go through guard rails all the time. You haven't lived long enough to see any accidents @itsthecaptain17
@@trondialsingh594 Correct, primarily improperly installed guardrails. I too have seen what it looks like to have a guardrail spear through a person due to being improperly installed. I've also seen what it looks like for cars to collide.
Properly installed guardrails work pretty well. Poorly installed guardrails, which are unfortunately pretty common, function poorly.
Given the light damage to the car, I'm thinking that any average sized car will look the same.
Where is the fire ?
It's Ice cars that burst into flames on impact , a lot of Tesla's use LFP batteries now which are very hard to get to ignite , you've obviously been watching too much MSM !
Fire don't matter if your flying of a mountain.
EV battery burning is very unlikely, in most accidents EV against ICE if a car burns, it is almost everytime the ICE car. Lot's of dumb myths and fakenews out there... obviously targeted campaigs to discredit EVs.
You see the fuel line got cut from the metal slicing everything under the car. Including the oil pan. The hot oil touched the hot exhaust and it caught fire brining a spark to all the gas spraying everywhere. The car was engulfed in flames before it even came to a rest. No? What?
Contrary to what EV naysayers think, EV + crash does not equal fire.
Model 3 has amazing safety, driver would be most likely unharmed.
If you look you can see there was almost no cabin intrusion, windshield was still in place, albeit cracked.
But everyone behind the guardrail would be dead.
… as it goes flying off a cliff or embankment because the guardrail couldn’t hold it back. That’s what I’m worried about.
@@Fabulousprofound168 have you heard about the man that tried to kill his entire family by driving past this exact same style barrier then falling 250ft and cause of the safety factor of Tesla cars, the entire family survived?
How many people do you see hanging out behind highway guard rails?
Seems like the whole guardrail is a failure and was woefully inadequate to begin with. There are large SUVs, pickups, and trucks that are way heavier.
So the point is those guardrails are poorly designed. Because the Model 3 isn't that heavy, and every car's goal is to lower the center of gravity for better handling.
When looking at the thumbnail, I suspect we have a clue that it is designed to be at a height where most of the densest parts of an average vehicle resides - the engine, but with an EV, the battery would be at or below the bottom part of the guardrail, so it would not have much effect to slow the momentum of such a low center of gravity. Just a guess and I could be completely wrong there. I'll take the automated safety systems to protect the car from going straight into the rail at that angle and speed and the added safety of very low likelihood of rollover any day though.
I guess time to go all jersey barriers then...
never mind, the most sold vehicles by far, even more so in TX, are full size pickup trucks. Much heavier than the average electric vehicles. Never heard so many concerns about that, in the past.
Shouldn't those rails be connected via a steel wire to prevent detachment?
And that wire would then slice through the car and decapitate you ? Or your kid on the back seat ? Doesn‘t sound like a clever idea.
@@pan6593 No, the wire holds the barrier together , you can look it up, it's already a standard practice.
@@pan6593 cables like that have been in use on highways for a very long time and have proven to be extremely effective at preventing head-on collisions from vehicles crossing highway medians when they lose control, WITHOUT slicing through the cars, as demonstrated in the countless car crash compilation videos on CZcams.
There isn't much information here on the parameters of the test. With a gas vehicle, they naturally coast when they have momentum and no accelerator applied. With EVs, the motors themselves apply braking. How did the team testing this account for this to ensure a realistic simulation was performed? What would the difference be between a car where the collision avoidance system fails, but the driver's foot comes off the accelerator or if the foot stayed on the accelerator. I have to imagine there would be useful information between these three scenarios that could also be fed back to the manufacturer to design an even safer car.
Note that the Model is actually a very light EV... Most EVs are 500kg more heavy..
So those are a bit of a fail…
those guardrails?
Texas Transportation Institute failed it's own test.
Is the barrier made of paper? If this is the standard in the US, it's very weak.
Hi, professional guardrail inspector here. This is thrie beam guardrail which is stronger than W beam. Guardrails in the U.S are made of U.S Steel. This guardrail isn’t weak one bit.
Why do they test with a Model 3? It is actually one of the lighter EVs. Wasn't the point to see how "heavier EVs" fared?
Now do the hummer EV or Cybertruck
LOL! Useless test for nothing. The Ford Crown Vic from 1998 (2nd gen., EN114) was 1,8 tons - without passengers and without packages...
This is bs, why don’t you show some Hummer or ford trucks?
Блоки вкопаны в песчано гравийную смесь, а также имеются подкладки из массива бруса. Всё это снижает точность разрушения автомобиля.
Is it supposed to do that?
Hi, professional here. No, it is not supposed to do this at all.
Must I conclude from this that someone cannot spell 'three'?
The system was named after its inventor, Dr. William Thrie.
@@SunriseLAW Thank you for that - today I learned something new! Best, Rob in Switzerland
@@RobWhittlestone Actually, I made it up. I think you had it right. :)
This test shows just how bad a Tesla is. Just look at how far the dash moves inside the car, I would not want to be inside in this crash.
Tesla ❤❤
You really wanta be sitting up just a bit higher than those cabin piercing guard rails don't you.
Back 2 the drawing board
Whoops!!!!
electroshit
Wait for the fire afterwards
Just ask Paul Walker.
you realize gas vehicles are 61x more likely to catch fire right?
@@zeeboid lol you need to work on gas vehicles for a living, then you will realize how much better they are, safer, simpler. More environmentally friendly, but no you just keep drinking the coolaid
@@jamesocker5235 LOL yeah so... I've owned 54 vehicles (Soon to be 55), most have been gas, several EVs. a couple diesel. I service ALL my own vehicles including engine swaps, turbos, open-source engine management systems, battery swaps, the whole bit. You don't sound like you have enough experience. Tell me, how many EVs have you owned/operated/serviced? lol and you think I, am drinking Kool-Ade. :D
Because EVs are FAR FAR simpler, safer, easier to maintain. And I didn't bring envronMentalism into this. If you care about the environment, go plant a tree.
@@jamesocker5235 So what does working on a car has to do with anything? Engineers, working with designers and structural integrity, specialist, metallurgist, etc. work together to come up with the safest design possible.
These vehicles are tested for a reason, and at the end of the evaluation/data analytical process, the data is analyzed, and reported out as a fact sheet/document that tells you, and I as consumers, exactly how safe the vehicle that you may be driving or about to purchase are.
So nowhere in that equation does it require a mechanical repair license in order to understand the outcome of a crash test. Capeesh! Cheers 🥂
PSML at US road safety, historically always been shite, I think those barriers are known for being crap, that just proves it lol... In the UK Armco would stop a truck unless it overrides it and every main motorway has median protection with Armco.
Это у них а у нас это ограждение отрежит авто вдоль как бритвой и всех кто был бы в автомобиле.
ограждение бутафория!!!! не такое стоит вдоль проезжей части на магистралях! там гораздо прочнее конструкция, и рассчитана на демпфирование удара автомобиля. Было бы настоящее нормальное ограждение, последствия теста были бы куда плачевнее!!
Ah! Ah! Nice try! Tesla (an American company) wins again!😊🦾🇺🇲
Who do you think made the guardrail?
@@dirkvornholt2507 All are know is that TESLA makes the most American made cars. And that's awesome! 🦾🇺🇲
@@kfk256 I know as a German Tesla driver. But linking patriotism to a car brand seems a little strange to me.
@@dirkvornholt2507 I'm sure you are happy when German technologies do well. So, you understand the happiness of an American about American technologies doing well.
It's not jab on you or anyone. It's simply about successful engineering outcomes by ingenious people in a country that encourages and supports ingenuity.
@kfk256 I'm happy if it creates well-paid jobs, wealth, and taxes for the community, but I don't think it makes a nation better or worse. Neither a brand makes a nation nor a nation makes a brand. The nation just influences the chances of a brand by supplying educated staff, and the brand pays taxes to fund education and infrastructure. Sadly, this symbiosis is kind of getting out of fashion.
