@@jmboberg6 don't compare a WRX and a WRX STI like that. There are a number of significant differences. An STI not only has a drastically stronger gearbox but it has a limited slip front differential, a dccd/limited slip center differential, and often a different type of limited slip rear diff. A WRX (manual) will just have a smaller lsd in the back and sometimes the center, with an open diff in the front. Even more unfortunately is that all 2015+ subarus have open diffs all around except for the old faithful STI
@@RChero1010 Owned a 2016 WRX and now a 2020 STI so I can speak on their differences. Even though the 2015+ WRX are open diff front, rear and center it uses the braking system to individually control wheel speed on each corner allowing the computer to direct the power where it needs to go. For instance, if all three corners on the WRX are free spinning due to low traction, the computer would see the three wheel speeds higher than one and will apply the brakes to those 3 wheels causing power to immediately divert to the one tire with traction. This allows them to get away with open diffs while having great AWD capability. The STI on the other hand uses LSD's to lockup the drivetrain and deliver power to all 4's no matter what.
Id have to say it's actually not very surprising at all. There is nearly no weight on the back of the WRX and the STI. This is why instead of finding traction it'll just spin. Traction just gets defeated to easily.
@@layne4376 I own a 15 WRX with a ton of work done to it. Trust me I know the platform. The laws of physics don't care how capable a car is. When the only tire making traction doesn't have the weight over it necessary. It will not be able to move a vehicle that weights 3400lbs. Which is why you see when the car is in reverse and 3 wheels are on the rollers and the one tire making traction is on the rear you get what you saw. The tire will just keep on spinning. But don't worry I don't know what I'm talking about.
I can confirm the 3 wheel in reverse. I got stuck one winter paralleled parked downhill and had to back up to get space from the car in front of me. Turned out 3 wheels were spinning even on lock dccd. Most embarrassing part was i had to get out of the car and tell the person in front of me to give me space..she replied isn’t that a subaru awd? …first time i didn’t know what to say..🤣
2:52 Some of these its getting grip on the side of the roller and shooting it out. The best would be the inclined roller test where the rollers are all attached to one structure. Still though, the STI is one of very few cars that can drive with one wheel.
Thank you for this test, this was very interesting! Seems the STi awd system is very good, even the tire on the ground gets enough power to spin on tarmac.
I love these tests. It highlights 2 key flaws in most of today's AWD vehicles. Lack of power is my biggest complaint, and poorly designed AWD systems is one nobody ever thinks about.
well subaru is known for fantastic awd performance. the sti is just less tuned for this sort of test than their other cars because this is more road and rally tuned
@@artilleryisbetter I true, I doubt it though... the lock rates need to be changed! Much like a Kia Stinger GT... either it'd LSD or ESP needs to be changed because both together is crap! Hardest car to control in a drift! Ever heard of an Eaton TruTrac
Nice roller test, but if you only traction on one wheel, you're not moving, lol. If you watch, it didn't move till the side of the tire kicked off the rollers
I don't really expect any refined results since the car itself is tuned for better driving performance (this could be one of the last performance sedans with a manual and awd). I prefer this system than their CVT offerings though 👌
2:45 flawed experiment if you wanted to purely test the AWD traction. You're raising 3 corners of the car by 2-3" of those rollers while the non-roller wheel is essentially lifted. On a soft suspension&body vehicle it wouldn't make a difference but on a stiff suspension&body it can support itself on just the 3 wheels.
@@AdrianSanchez-ub3tb true but a better test would be with the rollers in the ground cuz that one tyre has less traction than a regular tyre on the ground.
Enabling "TRACK" mode will not help display the AWD of this vehicle in this particular test. Track mode allows the inside and outside wheels to rotate at different speeds in order to allow faster cornering.
Enabling Track mode, reduce the TCS intervention on our roller test that nearly got the car to die on the roller even at full throttle in the situation where you see track mode enable
@@CarQuestion locking the c. diff., I noticed the front wheel move off the roller and power cut out. Isn’t that how one would burn transfer clutch packs doing that? Really considering the ‘21 WRX STi but am not sure.

The sti has the most robust and reliable trans, axles and differentials. The locking center diff and limited slip differentials front and rear really make them rip and grip. Now we just need an engine capable of 500whp with out exploding 😂
The new type ra engine block 706 series comes on every STI from 2018 up. I heard it handles 500whp very well. New thicker pistons and a few other design upgrades. I installed one recently on my 06 STI 👍🏼
Granted I only have a WRX with a torsen rear, none of the STI fancy. But I'm yet to be in a situation wet or dry, tarmac, gravel or mud that I could not safely drive out of a shituation, and that on performance tyres. Subaru make cheap parts bin cars, but the AWD system is legendary.
Can’t even say that was aggressive… u want that clutch to engage as quickly as possible than get up in the rpm range where all that torques at. It’s a stick, manual. It doesn’t have a torque converter that allows u to “build” torque steadily like in an automatic.
Don't mistake slipping off roller over actual overcoming traction loss. From what I saw if 3 wheels have no traction that car is not moving unless it slips to the edge are another wheel gets traction. You can see it here but looks to be from aggressive throttle 1:43, 1:54, 2:06, 2:18, 3:26, 3:41. Still a nice test to see a STI but not what was advised on some Subaru videos like this one ruclips.net/video/2OzK-oRPCbs/видео.htmlm24s Curious how the WRX non STI does with it's 3 open diffs
Actually the regular wrx should do just as good since other Subarus like the Outback, forester, and Crosstrek performed great on the same roller test and that’s with all of them having open differentials, I guess what helps a lot and what should get most of the credit is Subaru’s very capable and legendary symmetrical AWD system which got better and more capable with the introduction of Subarus dynamic differential torque split that distributes power to the tires with the most grip not only from front to rear but also from side to side,…..hell yeah thug life!!
Not really a good test. Dumping the clutch you could easily see the only reason he came off the rollers as it drove off the sides of them where it could get tracked beyond the rollers. In the test where it seemed fail, he was actually centered on the roller.
It was only twisting about on the rollers because of how much power was going to the wheel(s) with traction. I did notice it too but it wouldn't have happened if the AWD was worse
Any one else notice that the car walked to the edge of the roller then got traction where it was on the edge? Not saying is a bad car by any means but it's not what I would call a good test.
I was gonna say you're putting those diffs to work but they pretty much use electronic sensors to brake spinning wheels and send power to the wheels not spinning
Not surprised, it’s a Subaru. Better not let another RUclips channel see this. TFL won’t know what to do, apparently Subarus fail roller tests. 🤷🏽♂️ I like that blue. Nice wheels
Subaru has the best traction, but many times on test the tire reach on the border of rollers and get traction on there... Big rollers will make a better test.
Try making another platform that dsnt gave any rollers..that makes the wheel that dsnt have rollers be on equal height as the ones that have rollers so that all tires have equal pressure and not being lifted when the three other tires are elevated.
Now try a Subaru without an LSD or traction assists. My old 2007 Impreza wagon was only good in the snow if 3 wheels had contact to the road. It didn’t have a LSD unlike it’s Forester counterpart. Don’t miss it lol. My 04 CRV manual 4WD was better in the snow and it also didn’t have traction and/or electronic assists or a Limited Slip Diff.
Yo quiero saber que pasa si la rueda delantera izquierda gira para alante y la delantera derecha gira para atrás que es como lo hacen en la inspección técnica de vehículos, teóricamente al ser un torsen no bloquearia
That was scary to watch especially 3 wheel test where it get traction after it hits the side of the rollers. Can't thank enough for taking risk and doing these tests. BTW recently I've heard Honda / Acura i-VTM4 is better than Subaru symmetrical AWD. Only you can prove if its true or false. I'd love to see similar test on my Toyota 4WD system without engaging lockers. Of cause the locker beat every technology but love to see how A-trac and other multi terrain modes (Mud, Sand, Dirt vs Loose Rock vs Mogul vs Rock) can handle 3 wheel slip test.
The i-VTM4 system is prone to overheating under heavy use. Driving Sports TV took both an Outback and a Passport over the same cross cut climb, both made it, but only one had it's awd system overheat in the process, and it wasn't the Outback. I know the i-VTM4 system is a good system, I would say on par with Subaru. I personally don't see why Honda doesn't use it across their entire AWD lineup instead of having 2 different systems.
@@niuhuskieguy ohh really? They can overheat? As for the availability I think across the board Acura has it right? (I'm assuming all sh-awd is i-VTM4?) I think Honda started using after 2016 Pilot and now with Passport and Ridgeline. After that I see Toyota started similar tech with hand full of models. I was thinking why on earth you don't use the new AWD system across the board. Thanks for sharing, I didn't know.
@@BMW_DAILY I don't know I was thinking the same, But according to "Driving Sports TV" Honda i-VTM4 is better than Subaru. ("Driving Sports TV" owns a Subaru).

@@storejoshupritethey just change throttle mapping according to the owners manual. I have found the same thing in my own experiments during 8 months of ownership with the car
absolutely it is a test to show how good it did. If you compare it to other 4WD/AWD systems, I would say it did fucking great. Take a look vs other here: ruclips.net/video/2OzK-oRPCbs/видео.html
As a Subaru owner this was kinda bad tbh especially for a trim car like this… there was too much wheel before the other wheel or wheels would kick in… and in a real world situation that time matters as well as constant grip… and let’s be honest if you own this car you’re not gonna go easy on it majority of the time. Could explain why they are a lot more crashes wrx’s and sti’s in junkyards now.
great that you did the test. but why are you dumping the clutch. why not just drive it normal? also most of those test were fails. the car would slide to the side and grip the outside edge of the test equipment for grip. almost seems like you guys tried really hard to make this car seem better than it is
We do no try to do a pass on something that will fail. This kid of comments is and insult to what we do! As we said in the comments: enabling Track mode, reduce the TCS intervention on our roller test that nearly got the car to die on the roller even at full throttle in the situation where you see track mode enable. We send the power required to get the car running so it wont stall on the roller.
Wow it sounds like it's breaking just to move you one inch. And he had to rev it like crazy just to get anything to happen. Did very poorly on a few of those.
I prefer Quadra drive 2, so much faster transfer to one wheel, maybe half turn of the wheel and jeep already transfer all torque to one wheel, Subaru 2024 is like jeep in 90's
Not accurate test. Kinda wasted time testing the car this time imo. sti stock summer tires seem to just slide until one of them touches fixed metal frame. That's why it's exiting the rollers out not straight line unlike other SUV roller tests. But no doubt, subie will get out any rollers easily any day.
Very impressive! The sti's sporty suspension doesn't have alot of wheel travel . It would do better if the wheels are level. I would like to see this test with newer high tech awd like the focus RS ,GR carola Gulf R, GTR , BMW, Mercedes
Roller / Slip test note: Whatever mode you are on, this car will rip the tarmac to get you where you want to go!

I'd be curious to see what effect the different drive mode have with this kind of test. One would think that they'd make a difference here.
The drive modes just change throttle response. Wouldn't make much difference.
@@ianholmquist8492 They would also change traction control and esc strategies. In such roley-poley circumstances, changinng would make most likely make a difference.
@@storejoshupritethey just change throttle mapping according to the owners manual. I have found the same thing in my own experiments during 8 months of ownership with the car
A real power of sti.
Though i liked 08 sti generation of sti i think sti was more honest in terms of technology given
i can smell the clutch in this video lol
You should have your nose check because there was no clutch smell. Maybe your mouth is too close to your nose
@Car Question nah bud you burned the clutch
@Tyler Schneiderman change your diaper please
@@QuestionAuto1 stop destroying a perfectly good clutch 👌
Why so much/such agressive throttle…?🧐
wow... The 4wd is amazing..
*AWD
Are the clutch dumps necessary?!😢
Yes
This is a test that is better suited for 4wd vs awd. Interesting results.
why are u giving it so much gas?
What's the marble sound
Does it hurt the transmission when it suddenly grips after rolling off the rollers - if both left and right get tarmac at the same time?
It's a rally car, not a Honda Civic :)
I agree the transmission on sti is one tough machine..
No way it is stock drivetrine. Owner put limited slip diff on front and rear ;)
100% stock
Very good test for Russian winter
Why are you reving it up so much?
このSTiめっちゃかっこいいな
do you test new yaris gr like this?
It's not available for now here in Canada, but it will come one day.
I don't get this test lol to simplify it did it do good on the test ?? Is it a good awd system?
yes it was good
absolutely it is a test to show how good it did.
If you compare it to other 4WD/AWD systems,
I would say it did fucking great. Take a look vs other here:

As a Subaru owner this was kinda bad tbh especially for a trim car like this… there was too much wheel before the other wheel or wheels would kick in… and in a real world situation that time matters as well as constant grip… and let’s be honest if you own this car you’re not gonna go easy on it majority of the time.
Could explain why they are a lot more crashes wrx’s and sti’s in junkyards now.
great that you did the test. but why are you dumping the clutch. why not just drive it normal? also most of those test were fails. the car would slide to the side and grip the outside edge of the test equipment for grip. almost seems like you guys tried really hard to make this car seem better than it is
We do no try to do a pass on something that will fail. This kid of comments is and insult to what we do!
As we said in the comments: enabling Track mode, reduce the TCS intervention on our roller test that nearly got the car to die on the roller even at full throttle in the situation where you see track mode enable. We send the power required to get the car running so it wont stall on the roller.
you can put all 4 rollers on
What a great machine !!!
I want to see r35 GTR awd please 😏
Would love to see the Kia stinger/g70 do this
Korean junk
Best AWD system ever made
Wow it sounds like it's breaking just to move you one inch. And he had to rev it like crazy just to get anything to happen. Did very poorly on a few of those.
Dam those tires are so thin. Pirelli P zero will beef it up
Most of time car slides off the roller then got traction
I prefer Quadra drive 2, so much faster transfer to one wheel, maybe half turn of the wheel and jeep already transfer all torque to one wheel, Subaru 2024 is like jeep in 90's
Thank you!!!
Im surprise with 3 wheels test in reverse. I thought subaru can pass all of this but it still a good AWD car 😆😆😆
pretty much no weight on that tire
We need ascent on rollers!
Amazing STi
I can smell this video
Stop farting
hahahahha tooo much violence from the subi sti it jump away from the roller
It's not a gentle car ! Brute and crude but so much fun !
Impressive!!!
Subaru the best car
There were several instances when the car only got traction after the tires drifted to the edge of the rollers. Not the most scientific test.
Not accurate test. Kinda wasted time testing the car this time imo. sti stock summer tires seem to just slide until one of them touches fixed metal frame. That's why it's exiting the rollers out not straight line unlike other SUV roller tests. But no doubt, subie will get out any rollers easily any day.
Already see oil on the ground
It’s me or the guy just give more throttle that actually need ?
🔥🔥🔥
Very impressive! The sti's sporty suspension doesn't have alot of wheel travel . It would do better if the wheels are level. I would like to see this test with newer high tech awd like the focus RS ,GR carola Gulf R, GTR , BMW, Mercedes
Блин какая же она офигенная
Half of these tests…the car is only moving because it rolls off the rollers and hits the border of it for traction…
The car get out of roler because you slip to the side, on edge of roller...
