Conclusion: As long as you don’t need AWD, this AWD system will work for you.
if I get stuck in this thing and peak out the door to see the tires arent even spinning 🤬 as somebody who relies on my CRV’s AWD system from time to time.
Agree. Must people who purchase a Prius care the must about mpg.
I don't think Its a traction control issue. It worked well in the front. But I really don't understand how nobody in Toyota can figure out the AWD. However I'd love to see it in the snow rather than rollers. I'm starting to think the software struggles specifically with the rollers. Not trying to defend it as other cars don't have that problem but this happening across the whole hybrid range.... I don't know, there must be something else happening that we don't know about. Still, really good looking and practical car. And as I said traction control looks pretty decent now so I would just go with the fwd and with the money I saved install some snow tyres and go on a ski trip to test them :D
In certain situations, this system fails exactly the same on rollers and on snowy roads.
@pablomoreno1999 Snow tires aren't going to help, if the car can't transfer power to the wheels properly.
After seeing this slip test fail on the part of the new AWD Prius, I see little incentive to spend the additional money for this feature.
Just buy FWD and a good set of spare snow tires and wheels.
Thank you Tommy for providing this useful information.
Yeah this is why I'm getting a Prius Prime instead. Plus it works out to be cheaper than the regular hybrid due to all the Federal/State EV tax incentives you can get for it (provided you lease to get the Federal incentive).
@@justinf79 For some people it may work out to be cheaper. Those tax intensives only work out if you actually owe that much in taxes. Its not like they cut you a check.
Snow tires do wonders indeed!
@@Subvaries That's not how it works anymore. Especially if you lease.
What about steep dirt roads? Snow tires don’t work when it’s 100 degrees in July on an Arizona dirt BLM road
With new car prices soaring, please also do this with older generation cars. 3rd Gen RAV4, CRV, Foresters etc...
They have a lot of vids on those vehicles going years back on the channel.
The front tyres caught on to the edges of the rollers, that’s why it ‘passed’ the test. I’m surprised you didn’t realize that.
I don’t think it’s down to the lack of power at the back. 40bhp is plenty enough to push the car forwards. It’s just a poor traction control system. Toyota obviously needs to put in A-TRAC and a rear diff lock on this.
glad i'm not the only one who caught that! tires caught the edge of the roller hardware for grip, otherwise it would have been stuck. that test was a fail.
TIRES**
@@user-do9ir8lv2m That is the American Spelling, British English spell it as Tyres. Both are technically correct but also incorrect lol
It's the traction control. I used to drive Prius's for a livery company maybe 10 years ago and the moment the car would detect slip it just cut all power. It's funny to see 10 years later it's the same.
Well, given that he turned off the TC, and still couldn't complete the 3 roller test, I'm gonna say it's not the TC.
@@bavarianbanshee it might be a combination of both. There is a sequence you have to do to fully turn it off. Press start/stop twice, hit the gas pedal 2 full times etc etc. in any case the Prius traction control is terrible. I don't know why Toyota thinks cutting power is the right thing to do in that scenario
@@maverick7526 It's so the rear tires can't slip before the front tires and a Prius driver isn't confused by oversteer. Letting the rear tires slip a bit would provide better handling, but someone who had only driven front wheel drive might not consider it benign.
@@maverick7526 that's how you reset the maintenance light turning off traction is just a button.
@@sierratough4934 no in older Prius's that's how you fully turn off traction control. Hitting the button doesn't fully turn it off
As someone who owns a 2023 Prius, it is amazing in Montana and Colorado snow. It is clearly better than my FWD cars on the same tires. I'm not convinced that the roller test is as relevant for paved road use in poor weather, as opposed to off-road use.
I do understand the difference between AWD and 4WD as a modded 4Runner owner, too.
If you watch Matt's Off Road recovery , he turns traction control off in every type vehicle he tries to rescue. Traction control for some reason does not help when you are stuck somehow.
He had it turned off. its because it cuts engine power.
I don't think the slip test yields the same conclusions I found driving a Jeep XJ on snowy highways. The Jeep had dual switched lockers which I never ran on the highway -- only off road. So in 4WD open differentials it also would have failed your slip test. But 4WD made a massive difference in highway snow/ice capability. 4WD on and the Jeep tracked true though packed snow and ice. 2WD and it oscillated back and forth --- very unnerving at highway speeds. I would expect the Prius AWD might have similar characteristics. More stable on snowy/icy highways than the 2WD model. So while I'm a fan of testing, it needs to be confirmed with real world use. I suspect in this case the testing is misleading.
looked like front tires hit corner of roller.
They forgot another A. AAWD. Almost All Wheel Drive. 😂
Great video. Good to hear discussion about traction and ground clearance potential issues. Love how the design looks, but not the practicality
Thanks for the video. Definitely disappointed in the AWD results. Folks in the north need honest AWD.
Go buy actual AWD then like Subaru, stop whining
I have a gen 2 prius and thought about upgrading to gen 5. But I didn't like that they removed alot of space for the "aesthetics" and my gen 2 has gotten me out of heaps of snow. They really over engineers gen 2, so I still think it's better than even gen 5 at some things.
Can't wait to see the new Camry test
Slip test on the sienna please!
I think I miss heard a few things, AWD? more like front wheel drive. Back tires don't appear to do anyting unless the car is already moving. But worse I think I heard him say it looks good. I didn't see anything good looking in this video.
I agree. The car is not the nicest thing out there.
Great video! I'm glad you put the new Prius through its paces in the slip test. I was considering an AWD Prius to replace my 2021 AWD CX-5 when the lease is up, but I might have to reconsider. I certainly don't need AWD here in San Diego, but my parents moved to a cabin in the northern tip of Idaho (one mile from the Canadian border) so AWD is handy for driving up in the snow months. But ground clearance would also be just as helpful, so perhaps the Prius isn't a grand idea anyways. Perhaps I'll just exercise the purchase option at the end of the lease, although I'd really appreciate something with significantly better fuel economy. Maybe Mazda will finally release the CX-50 Hybrid by then, although it remains to be seen if they can improve on the Toyota hybrid AWD powertrain that it is inheriting from the RAV4.
I grew up in the northern tip of Idaho, Priest Lake, i could be in canada in 30 min! Miss it every day! And yes, a decent AWD vehicle is reccomended!!
Just remember, if you need extra traction control, turn off traction control. Lol
That's why I don't drive with traction control I usually turn it off
The only way to really test the awd is to take a fwd and awd model and compare them together on snow and ice
this is telling in how the awd system gets you going from a stop.
Na. This test is better
Can you test the crown xle please
The 2005 charger we had could pass all of these easily.
Guess ill keep the ram with a trac lock. I would be pretty upset buting an awd car that couldnt make it up my droveway. Its also kind of scary the torque making the vehicle kick like that. Ive had a few awd/4wd vehicles that were much more stable in the snow. Not ones that are set up to be a if you get stuck assist
9:48 Doesn't it have the 2.0-litre (M20A-FXS) engine in the States?
Yes. Tommy misspoke. It is a 2.0l i4.
This is due to the smaller diameter tires sitting deeper inside the rollers - which means they have more resistance to overcome to get UP and out of the rollers. It’s not as much about the awd - in my estimation. In snow or ice, it would likely be the match of any awd car with these tires
That foam material is wild
Toyota's hybrid "AWD" system is borderline false advertising. The rear axle has consistently proven to be useless
Not useless. Not driven.
It everything but not useless! It's not for offroad and it actually works very well in the real world lol!!!
@@alanmay7929I guess the TFL driveway is an alternate universe and reality. 🤡
How lol
@@wolfgangpreier9160 synonymous. The entire point of AWD is to power both axles. If an axle has no power it is useless.
8:01 That front driver’s tire actually hits a bit of the rollers frame and catches some traction (played it back at .5 speed). Did it “really” pass that test?
Yes it did pass the test regularly. I was pushing from behind. You can't see me. I am the Toyoda family ghost.
Toyota is programming the car to use its AWD in a different manner. 15K on my '23 AWD prius and this test gives me the heebee jeebies about taking the car up into the mountains. I haven't had it in snowy conditions at all to say it will do better there or not but I sure would like some feedback from your contacts at corporate on the test results. Why would I buy an AWD prius again if AWD doesn't work like I think it should?
8:02 actually the front left tyre got grip at the roller frame and as result the car was able to pull away, this was a failed. If you do another test you will get stuck most likely
esc cutting power quite obviously, the rear could also use a lsd.
I wonder how the awd Toyota Crown Platinum will do on the slip test. It’s got a drive shaft for the rear axle instead of a motor.
It doesn’t, the rear axle is still an e-axle, but it’s 100hp instead 40hp in this car.
It actually looks good as far as PRIUS design comparing the past models.
I wish they still have the light color interior, black is very hot in California summer.
To avoid pushing the vehicle your testing whenever it gets stuck, you should redesign your rollers to have a lockable rollers. Or some rubber pads that you can tighten on the side of the rollers that you can tighten to lock it.
SWD... Some wheel drive.
So, now I'm very curious to see a new 25 model year camry pull it off.
can the electric motor take more power and is anyone modding these things?
Wow, that is not good. I never found a problem in the snow though.
Hopefully Toyota will use OTS update to fix the 4 wheel drive issues
Toyota Hybird is designed with fuel economy as priority , than reliability and than as last priority comes performance or whatever there is left for it .
Even that they improved driveability over the years their cars are build to sell and obviously it sells very well so they have no resson to make cars with performance, engagement, tight road feel in mind .
It’ll be interesting to see how the new AWD Hybrid Camry performs.
Please test 2025 Camry awd
Traction Control just gives the driver a false sense of traction. I never liked the idea.
Finally I was very curious about a Prius behavior on rollers , Thanks
This is one of the prettiest cars on the road today. If money was not a problem, I would buy one just for its looks.
The Prius will always be an ugly car
@@SavoyPrimeableI had an LR4 in 2014 and while it may be decent looking, but it had catastrophic failures at 88k miles. I’ll take the ugly Toyota over another Land Rover any day.
@@SavoyPrimeablebeing so close-minded like that won’t get you very far in life
All he had to do was switch it into Rock Crawler mode to lock up all three differentials.
...i know this should be an indictment of the AWD software... but imho, this is proof positive that there should always be a way to turn off traction control. Cause sometimes, you just need some wheel speed goddamnit.
We just finally got our 2024 Prius Prime after a 21 month wait, a month ago. It's our third one but first plug-in. So far we love it.
The Prius we traded in was the C model and it served us well for 12 years. One bother with it though was the Traction Control. Our winter climate here is best described as temperate. It hardly ever gets colder than -7 or -8 C (for those folks still using Imperial measuring, that's about 46 ~48 F), and days closer to 0 c (32F), are common. However, what this means is we generally get a lot of wet, heavy snow. And it's hard to believe how fast snow can accumulate.
With the C model the Traction Control could not be switched off (unlike with our first Prius). So, when ever snow built up on our always hilly roads you weren't get anywhere. It refused to spin the front wheels. In reverse gear the TC did not work though so if you were lucky you might have been able to back your way out of trouble.
The new Prime has a switch to defeat the TC thankfully.
It needs to be pointed out; Traction Control in any car is not there for the purpose of getting your car "unstuck" from snow and such. It's designed to help the driver maintain control when the roadway is slippery by selectively increasing/decreasing torque to all the drive wheels and or, applying brake action to wheels independently with the aim of keeping your car under control.
9:49 1.8liter Engine? I tought its 2 liter.
It not meant to be true one. Just to get you out of small bind like nice. The last one had 7 hp AWD. But mine gets 50 to 100 mpg
I had a 2008 prius for 10 years. It was fantastic. It allowed me to travel alot and got me back and forth to work too...if the weather wasn't scary. I bought a subaru forester after that and both are great cars. If you need to occasionally go through 6 inches of snow or more do not take the prius. The traction control is so over aggressive it won't even budge. Luckily my wife has a 2012 forester and when I stole it everytime it floods or snows in Newark NJ I said that's what I need. She got a ride in locally from jeep owners and works 2 miles from our house so don't hate on me🥺
It’s definitely not a motor size problem but a TCS problem. The hp and torque should be enough to actually move the car fairly easily.
I am curious if the Corolla Cross Hybrid would perform any better, on paper the powertrain is very similar to the AWD Prius, but Toyota had been known to have pretty great traction control programming for their SUVs.
Much better!
It isn’t similar, it’s the exact same drive train, just in a crossover form factor.
In the real world, the AWD could be useful in certain situations but ultimately the electric and gas engine helps just a little bit for traction😐
I don't think Its a traction control issue. It worked well in the front. But I really don't understand how nobody in Toyota can figure out the AWD. However I'd love to see it in the snow rather than rollers. I'm starting to think the software struggles specifically with the rollers.

And as I said traction control looks pretty decent now so I would just go with the fwd and with the money I saved install some snow tyres and go on a ski trip to test them :D
It's not the problems with rollers. Recently I made a video comparing the awd behaviour on rollers vs snowy road, system fails the same way.
@@4x4.tests.on.rollersGood to see you here hehe!! I watched it actually, it was with the yaris cross... But this one has way more power on the rear plus TC seems a bit better... Maybe it's different i don't know. But yeah, it still needs sorting, i wouldn't expect it to suddenly become an audi quattro
@@pablomoreno1999 Good to see you to! Yes, it was Yaris Cross with 5 hp rear electric motor.
How the hell does Toyota's R&D department 1) not try tests like this, or 2) greenlight this after doing a test like this? Yikes. Toyota should be seriously embarrassed by this video.
Why should they? Ppl going to buy it anyway. N most if not all those ppl will never need to use 'real' AWD
@@omi8822because your still paying for that. 36k is a lot for a fwd
Have you noticed new toyota quality is in the tank
Have you done the corolla cross hybrid? Now I, curious how it’s AWD stands up.
I literally palmed my forehead when we learned he had traction control on.
Eh, I own the AWD version here in New England. It works phenomenally in the ice and snow.
I hate to say it, but maybe you need a better method to simulate real world low traction scenarios. I’ve been in many situations where AWD SUVs and trucks found themselves stuck in the mud or snow, but to everyone’s surprise, I was able to get out without a problem while they needed a push.
Objectively speaking, I like the idea of these tests, it would seem logical to perform the tests as you have been with the low traction rollers, but after this test, I’m starting to question its real world translation.
Recently I made a comparison of system behaviour on snowy road and on rollers - it failed the same way.
@@4x4.tests.on.rollers something is amiss here then. How are auto manufacturers testing? I know they have real world test mules in different climates.
My experience over two years in the snow and ice aren’t indicative of the sentiments in the video test. This video would lead me to believe that the AWD system is ineffective and a waste of money.
If I were a newly prospective buyer, a simple video like this could easily dissuade me from buying. However, as someone that knows better, I think it did more harm than good in demonstrating potential. Are we to believe what seems like objective testing or an automaker with a huge research and development budget?
I have been a fan of roller tests for years, but now I question this methodology since my experience isn’t mirrored. I drive far more than the average user in these conditions, so I feel a little justified in my reasons; not just speaking to be contrarian.
@@User.Joshua Roller tests do not show full view. They show some certain, usually difficult situations for the system. It doesn't mean the system is entirely bad. But it may show the system is one of the worst on the market etc. My previous comment was about the system using rear Q510 1MM electric motor, which sometimes fails in real conditions even more then in roller tests.
Nobody noticed that the other wheels are actually spinning on the concrete, the tires have no traction and system is wigging out cutting even MORE power 😂
That foam tray in the trunk looks dirt cheap. Like those foams you find unwrapping your new dishwasher... Scary cost saving.
That's because a spare tire is supposed to go there. The foam is an afterthought.
Test some good ol’ Subarus and put them on those spinners to compare how they do! 😉
It's common sense on the slip test when the front tires are on the rollers the computer system sees no need for rear tires 💯 it's all about fuel economy.
Is it also common sense to not use rear wheels when front ones are on ice?
Interesting. You showed the Rav4 and Highlander sffering similar issues. I assume the Corolla Cross Hybrid, also on the TNGA-C platform and sharing the same powertrain as the Prius, probably will perform just as this did.
My wife has a CCH and we pur hased the hybrid version not because it has AWD, but because it is the most powerful version of the Cross with good fuel economy. We live in Texas where we rarely see snow, so I am not too disappointed. You can feel it transferring power to the rear in the rain, so I know it's doing something.
Put the Model T on the rollers 😄
You need to test the AWD in real world conditions.
Can we do the test on popular EVs? And ev trucks?
Awd car gets front tires off the road in the snow. Awd car is now fwd. 🤔
I think snow tires on snow will definitely give you different outcome results.
That snow tire wont help you if they don't power up the rear motor when the front is stuck
@@jack8356but snow tires will help your front not get stuck to begin with. I drove fwd sedans most of my Canadian life and with real snow tires I never really struggled in the snow. People who say you need AWD in the snow really are either just inexperienced or for some reason assuming everyone is offroading up unplowed forest roads in the winter.
So will snow tires on a rwd vehicle.
@@jack8356front tires don’t get stuck with snow tires
For a 45kC$ it should do a bit better I think 🤔 still not too bad.
I drove one of these in summer conditions last year. Isn't there an eco type mode to drive without gas power at all? I would have thought the rear could have pushed it of the front only rollers driven gently in that mode. But yeah, not a winter warrior, I'll take my Golf R for that thanks. I don't believe that's been tested on the rollers.
I suspect that it's not the rear motor itself that's the limitation, but the inverter. The earliest all wheel drive Toyota hybrids had some issues with burning out the section of the inverter for the rear motor when driving off-road. Later models probably restrain the amount of current allowed to the rear motor to prevent damaging the inverter. Because upgrading the capability of the inverters would probably be less cost effective
The Toyota Prius is more expensive than A Tesla Model 3+ So there is that for a hybrid car (probably the best hybrid of all)
The diff was too much open in this car. Ya
Get some snow tires
thank you. this made me sad. really enjoy the look. had the gen 2 and this one peeked my interest. guess I will pass on the awd could this maybe software? since we know the other hybrids can.
Would be interesting to see what the BRZ4X’s AWD is like, and see if it is any better since Subaru has the equivalent car and Subaru is a pioneer of AWD, and has one of the best AWD systems going.
You would hope that Toyota would see this and offer an explanation. This could likely be fixed by a minor software modification. This is also why I believe Subaru has a superior AWD system and I am looking forward to their PHEV models.
Coukd they fix it with a software update in theory?
That thing has the skinniest tires I've seen on a car since the BMW i3...
I’d want Toyota to reimburse me for my car and take it back over this. This is terrible advertising and I shouldn’t have to turn traction off to get AWD working 🤦♂️
Reimburse you for what? They advertised this as an AWD drive vehicle not an off-roading vehicle. Crappy AWD aside both axles are powered, if it’s not good enough for you then get the FWD model, save some money, and have an added range benefit. Also if you plan on driving around in the snow you should have good set of snow tires anyway.
I’ve consistently been skeptical of Toyota’s hybrid AWD setups. It’s a real shame that even their latest in the Prius is basically a joke. If it can’t accomplish these basic tasks, it serves no practical purpose at all. Might as well save money and weight and just get the FWD models. Super disappointing, given the disconnected front and rear axles actually gives Toyota a lot of opportunity to make the AWD very effective.
It’s the traction control. When he turns it off it works.
@@djplonghead5403 Except that turning off traction control helped in one of the scenarios, not all.
it provides benifit when the car is moving and on slippery conditions but just not in these extreme test scenarios. I do agree that you are most likely better off getting the fwd version and maximizing your gas savings. I would love to see a wet test track test a slalom and a figure 8 on the awd prius versus the front wheel drive. Also 0-60 of the fwd and the awd.
@@BassRacerx I think I’d rather just put snow tires on a FWD Prius for the few months of the year most might actually benefit from an AWD car (if the AWD system were up to snuff).
@@davidc-l9174 i don't subscribe to the all Wheel drive and all seasons mentality. However I live in south alabama where there is zero snow so you can run all seasons or even summer tires 365 days a year.
Now people want 52mpg and expect be able to go over landing all for $35,000. Unbelievable. The comment section is comical.
Traction off. 👍👍
40 hp motor should be able to push that car off. Maybe its doesn't have enough torque. Well the camry e awd might be disappointing with the 5 hp or was it 8 hp rear motor.
It should have enough torque. It didn't look like it was even attempting to use the rear axle. That's a programming issue.
Oh man no good
@10:30 did I see “Mattel” written on the rear motor?!? 😂
Or maybe 1WM stands for “1 wimpy motor”?
So you turned off traction to get more traction. Too much saki at Toyota 😅
So, the moral of this story is don't buy and AWD Prius, it's not worth the money. If you buy a Prius and have a place to plug it in, get the plug in hybrid. More power, better gas mileage and electric only for 40 miles. I've got a 2012 Prius that I purchased new and it's still running with 290k miles on it. MPG has dropped from 52 to 46 overall, and had to get the head gas get replaced at 260k, but otherwise trouble free. Pretty much paid for itself over the years will all the miles I drove and got reimbursed for about 50k of the mileage at .55 cents per mile.
Nah, these rollers don’t simulate real world conditions properly. I own a previous gen AWD Prius and the new plug-in version. I live in New England with tons of ice and snow in the winter. The AWD has performed well on stock all season tires. I have experienced many scenarios where people nearby in SUVs and trucks need a push and I simply drive around them. Not sure where this test fails in replicating low traction scenarios, but it’s not indicative of how it actually performs with AWD.
@@User.Joshua Thanks, good to hear. I grew up in NH and went to college in VT, now living in IN, wife is a Hoosier. I miss all the snow and ice we used to get. Dad tough me to drive in snow on a hill in Brattleboro VT back in 1975 ... the good old days.
Honda and Toyota don't have the best AWD systems.
That's a joke. No one with safety in mind is going to drive around in the winter with traction off. Stick with FWD and get snow tires.
Attempt With Discretion
AWD is better than FWD
Good car.
Great review! This Prius should the best alternative for people that don't want to drink the Tesla Kool-Aid. But they did nothing but make a 3-ton paperweight when it comes to snow and ice. I'm really surprised that Toyota did not spend more time on this. Then, with the Tesla Model Y being the new number one selling car on a planet, why would Toyota not want to bring back, and perfect a Prius V AWD ???
The Model Y isn’t best selling anymore, I wish people would stop regurgitating that statement.
That's totally unacceptable in this day and age. The computer should be able to see the wheel that is not spinning and apply power to that wheel. The rear electronic differential needs upgrading if it's incapable of applying power to the wheel that is not spinning. I hope the new 2025 AWD Hybrid Camry does much better at this. Doubtful though because it's probably the same system. Thank you for exposing these weaknesses for us. 👍
So basically, AWD was a scam. Toyota slipping up a lot lately
"interior is phenomenal"... What?!? That interior is atrocious. The exterior styling is great, but holy crap is that interior bad.
Toyota can use the “slipping is bad for the CVT” excuse as to why the engine cuts power to the front wheels. I’ll accept that but still be dissatisfied. However there’s no acceptable excuse why the back tires in an electric drivetrain can’t compensate for that. Embarrassing laughable false advertising. There’s so much potential for this system to be phenomenal at no additional cost to Toyota. This will barely do anything in snow and absolutely nothing off-road.
its eCVT ..it doesn't have belts..its all gears..i agree..hte back drive motor is pointless stupidity.
😊
They use 7% of power in the rear. That's so it looks good on paper, not in real world conditions.
This test is, in a way, misnamed: it's less of an AWD system test and more of a traction/stability control test *on* AWD cars.
I'm a junkie for the "cars need real LSD/locker differentials" opinion, but I the more "rational" part of me also thinks that it shouldn't be too costly or time-consuming for the Toyota IT guys to program their system to act like a diff, rather than having these weird situations where half the system (such as the rear axle) just goes limp. If the left is spinning but the right isn't, brake the left so the right can get (EDIT) power. If the front is spinning but the electric rear isn't, give it some damn juice on the rear. As much as the driver's throttle position "demands".
"If the left is spinning but the right isn't, brake the left so the right can get torque" - that's actually not correct statement. As the diff is open, both sides are always getting the same amount of torque.
@@4x4.tests.on.rollers Right, power. They both get equal torque, but that torque is only equal to whatever is necessary to spin the moving wheel.
What's the point of awd if it won't get you out of a snow covered parking lot? I like Toyota.... but that's disappointing.
