I love that we talked about this in a previus video comment section and you're now settling it! You're the boss! Thank you.

I'd like to see the done in your mustang. All the nannies on, just abs, and everything off.

Off-roaders should have the option to turn ABS off with a button inside the cabin. The old G had it. It allows for better braking on loose ground because the tires create a tiny hill of mud/sand in front of them which also slows down the vehicle.

Kinda reminded me of my old Renault 4 I'd push the brakes all the way down but the wheels never lock ...cause it barely had brakes

What about 4WD with ABS on?

Ok, that was really cool and informative. But it naturally raises some more questions about real world scenarios. To elaborate, while threshold breaking is a relatively easy skill to learn, it would take countless hours of practice before it becomes instinctive. I can threshold brake, I used to drive a no-ABS car for first 5 or so years after getting my licence, I got somewhat good at it. And yet I'd argue that even pretty experienced driver's first gut reaction to impending disaster would be to push the brake as hard as humanly possible. This makes me curious about two things: 1. How does the ABS stacks up to intermediate driver like myself, who in an emergency would likely lock the wheels for, let's say, first second or so, then regains composure and starts threshold breaking? 2. How does ABS stacks up against novice driver who is likely to keep the wheels locked all the way until complete stop? P.s. Love your videos, keep up the good work!

can you guys do other test like this but with an older car like a BMW e46

Would definitely like to see more of this. Any new information or individual testing on ABS vs non is always appreciated, and cool to see.

Love it! Keep up the great content

Thanks again, Wyatt!!

I've read studies and articles done on this stuff. No ABS has better stopping distance at lower speeds, but the faster you go, the more ABS becomes the better option for stopping distance.

The only reason I have never needed to use any aggressive braking in the last 50 years is because I am a safe driver. I am always looking ahead and I always keep large gaps behind any vehicle I am following.

i'd like to see how no-ABS threshold braking is vs ABS, and maybe also threshold braking with ABS VS slamming the brakes with ABS. (and then also, pavement VS gravel VS snow/ice too would be nice; from my experience, ABS actually makes you a LOT worse off in snow/ice)

That was great! Keep it up!

I'm glad you brought up the 4wd trick. Most OEM setups are front biased for safety. They require the ABS system to transition that front bias to something closer to even. However, 4wd locks everything together which makes braking far more even. It's a nice solution. It's something that works well with the Subaru STI too I've found, although it won't dial out the front bias if trail braking. It's still nice to get the brake bias closer to neutral in the first place to allow better overall performance and to influence cornering balance if any braking is used during.

Was just about to do the same test with my own car haha, was literally planning how to do it, thanks :)

Man, Randy Couture has really hit the skids since leaving the UFC!

Wow interestingg. Thanks for the VID!

Next time you do this on a loose/slick surface test ABS using threshold braking. Don't just jab the brake hard, try to not break traction and let ABS only be a backup if you do. See if that beats no ABS? That's how I've always used it, and usually ABS never engages except in very slick conditions and even then not much.

Ok, so using time stamps I've got the following (first number - braking start, second - vehicle stops, third - time to stop) ABS on 1. 100.95, 104.02, 3.07 2. 144.52, 147.67, 3.15 3. 171.40, 174.24, 2.84 average 3.02 ABS off 1. 227.44, 231.28, 3.84 2. 289.82, 293.01, 3.19 3. 344.29, 346.96, 2.67 average 3.23 So conclusions - this test shows nothing, even though ABS outperforms on average. Tests should be consistent so if you use 4WD for non ABS braking you should use 4WD for ABS braking too. Much more test runs required to be done before any conclusions can be made. Speed need to be much higher to try and minimize influence of difference in speed between runs, 1MPH at 50 MPH is 1% and 1MPH at 100MPH is 0.5% (of speed that is, it might influence stopping distance even more because it's not linear progression). Test on wet asphalt is welcome too. And braking distance need to be measured not time, to reduce human reaction error for clicking the button on stopwatch.

"this is a stupid spot to turn around" Ehh, join the club Wyatt. Love the videos :)

Awesome video. Higher speeds would be awesome!

Entertaining test

Why do the bugs go nuts? Kidding aside, great video. I've waited for that one! Knew the one on snow of course. Do it with the Mustang when you drift it. Also use different quality of tyres for breaking and drifting to show differences of control and breaking distance. Good night from Germany. Keep safe.

The best braking is at a -18% slip angle if anyone is wondering - This is barely, barely shy of locking the wheels up. The extra friction causes the tire to slip and screech, but not lock and extra drag (friction) causes a faster stop time.

It would be great to see a video of braking where the factory brake pads and compared to after market brake pads in a similar test - ABS on and off.

Awesome video!!!!!!! I love brake testing!!!!!! I live in Pa so I have driven in my fair share of snow and I appreciate ABS but I also think it may be a bit overrated... I would love to see tests in slippery conditions with a car that isn’t equipped with ABS, like an old Golf/Focus compared to one of your Fiesta’s. I’d like to see if I’m being arrogant or if skilled drivers can overcome not having ABS🤔

Very good test, you could use cruise control for even greater consistency, and it would be great to see test like this on more slippery surfaces, like gravel or snow. On pavement it is probbably not a good idea to have 4wd turned on and abs braking, due to brake forces pulsing and stressing the whole drivetrain? Again, great video from your channel.

Now I'd enjoy seeing 4wd with abs on. I'd also imagine the braking bias has something to do with rear drums and front disk.

A friend of mine was using 4WD year round for a couple years because they thought it was automatic AWD. They complained about it "chugging" in tight corners before, luckily the vehicle wasn't damaged at all.

Hi guys! been watching your videos for a while, and putting your lessons into practice.. it it very well explained :) But one thing to ask: can you make a video on how to drift in 4WD car ? what to look at and how to control ?

I personally noticed that a well tuned ABS will usually allow you treshold brake really well, my Suzuki Swift (2018 model) allows me to brake extremely hard without the ABS engaging. Also noticed that slamming your brakes is not great with ABS, and downright dangerous with some cars; my previous car, a Seat Leon (2016 model) would almost refuse to brake if I hit the pedal hard and suddenly, it would just start vibrating like hell, pedal would get stiff but wouldn't slow down much, really scary but luckily always happened in "controlled semi-intentional" situations; it happened on dry pavement as well... I wouldn't disable ABS on the road but I do often disable (not totally as my car doesn't allow me to) ESP and TC because, especially on this Suzuki, they're really invasive and cut power way too much, the car is impressively stable though, the rear end slides out just enough but is easily controllable; when systems are on there no way the car is slipping or sliding anywhere whereas when they're partially off you can have fun as it basically only goes off when you're doing hard handbrake turns and never while actually driving aggressively. I didn't trust my Leon at all instead, it would lose grip without any warning and ESP would always end up making things worse, intervening late while you were already correcting and messing with you correction; it once almost sent me off the road because the rear end slipped out, I countersteered and the ESP just decided that because I was steering left I probably wanted to go that way so it just did everything it could to steer that way instead of actually correcting the oversteer, garbage system... I went on a rant that doesn't interest anyone not anyone asked about... lol

Did your testing account for hills, tire temperature, and brake temperature/fade? I'm loyal to motorcycles, and I know the sayings, "don't surprise a tire", and, "load the tire before you work the tire". For few seconds, I thought about excepting the costs, weight, and complexity of ABS. But I've decided to still rely on my judgment, training, and practice. I love trail-braking. I love gradually adding or removing brake-pressure, including releasing at lockup, then building again. And I love personal-responsibility, full control of my life, and mastery. This was odd for me, but still fun to watch. Thank you.

I wouldn't say the fractional seconds matter much here - I think there's a rather large margin of error with this method of measurement. I'm not sure I can take much away from this other than that EBD is important in a modern car. Probably better to use a set of cones and measure the distance.

Good video: ABS is best, unless your are trained in a controlled environment with 4 wheel drive. ABS keeps drivers from panicking sliding tires on melting rubber that makes the vehicle unable to turn. You can still turn while braking hard without ABS and leave black marks, but you have to release some brake pressure. Oh not to mention flat spotting tires without ABS. Of course a trained person can threshold in a shorter distance than ABS, but ABS is made to help everyone.

nice, i was actually really interested in this! Kinda shame... and a question at the same time...? Why did you pick heaviest car you could find? lol 🤣 this has been really poor day for me but your video made a bright point, so thank you! Appreciate the content as always! and yes please do more testing on different surfaces with different vehicles especially ones more... sport related like Subaru/Mits, Audi a4, BMW e36-e46 even X5 etc etc Cheers!

What are your opinions of enhanced oem offroad suspension vs aftermarket mid-length travel suspensions for trucks?

It would be interesting to see braking times without ABS, fully locking the brakes vs threshold

It is fact that abs elongated the braking travel distance required to stop (vs a good brake control w/o abs)... But the trade in distance they gave the driver a freedom to change vehicle direction during emergency braking situation to avoid colliding with obstacle... Thats why race car didnt use any abs because they want shortest braking distance possible... (Any directional change during braking task is up to the driver capability him/herself)

well time to see how my truck stops with traction control and stability turned off, vs standard. shouldnt be a difference, but good to know for sure

It would be cool to do two vehicles side by side. And instead of judging by time, judge by distance. I'm thinking 2 of the same vehicle, same tires, etc... The only difference is the ABS. Choose something where you know that brake balance is good with ABS disabled. (It would also be cool to see Stock (w/ ABS) vs Stock (no ABS) vs full race modified, lightened, performance brakes, etc.)

i’m curious if a predictive abs that lessens brake pressure before the skid would work well for this. super sport motorcycles incorporate this technology, where if you lock up the front youre going down.

Could you give us Weight transfer leeson?

What about a rwd only car? Can you do a video with the same scenario? Or what's your oppinion on that?

Would have been interesting to see what the time would have been in 4 WD and ABS. Personally I always preferred not having power brakes as you had more feel on the brake pedal.

Cool test. I have a fiesta st with the abs fuse pulled. No rear brakes! How can I change the brake bias?

Could you do the test again with something like a fiesta or a car that doesn't have stability control / whatever safety feature that was only giving you front braking? Also, surely if your abs fuse went in the Tacoma and you end up having only front brakes that would actually make the car less safe than having a car without that "safety" feature?

do this again on a track with some sporty cars!

what was the difference in braking distance roughly

My Lexus es330s abs system allows lockup to occur if needed and I can threshold brake with abs on no problem. I'll take abs any day snow, gravel,sand whatever my previous car had zero aids and never performed as well as this car.

Can ABS on higher-end cars or sport motorcycles perform better?

Fun fact: Automatics by nature will have a shorter braking distance than a manual; this is doubly so for awd vehicles.

I have a 90 e30 that came stock with abs. I bought the car swapped and the abs wasn't connected back up. One day I had to stop immediately and only the passenger front tire locked up. Is this an issue with brake bias being manipulated via the abs, thus the front passenger tire only locking up?

I'd be tempted to ask if attempting a threshold brake with ABS (Braking hard without dipping into ABS) would be faster or as fast as without ABS.

My ABS is disabled until I pony up $1500 for a new ABS control module. This test alerts me that I'll need an extra second to stop and I might be skidding the tires old school, and against auto insurance rules. I was wondering how I braked so much better last year for irritating sudden red lights versus days of yore; it's the ABS! I'll be in trouble at those same red lights now. It's also winter and ABS usually kicks in when I'm goin 10 mph in my driveway on the rough snowy road. Other people have their ABS dysfunctional for some reason and their speedometer and other gauges don't work. Makes me think the garage just took out fuse #2 to get a lot of moolah. But they fixed my wheel bearing and my car is up to 10 dB quieter on the road at 40 mph. They said they found a shorted wire near the bearing and it blew out the ABS control module.

Add some emergency brake will give you more rear brakes should bring it down to mid 2s And then if he could listen and get a feel for it little bit of practice should get it down to low 2s Plus smaller rims if you get 15s on there drop some tire pressure should get to two flat

Nice car seat. Is this your daily?

why u didnt do a brkate test with 4wd and ABS ON?

You could try treshold braking with ABS instead of just pushing till the tires lock up (as seen even in this video, locked wheels are not good at all) also better timing would be greatly appreciated, were talking fractions of a second difference here, a stopwatch is not really ideal.

ABS is more of a backup for user error (which everythign actually is), turning while braking (especially in the wet), surface changes (road markings, wet, dirt) and so on. I usually try and brake without engaging the ABS when braking hard, ugh that noise, but it has saved my bacon once or twice.

How about when you lock your wheels? How about threshold braking while having ABS on? Seems like ABS + threshold braking should be the best/easiest method.

Racing Line on motortrend showed that ABS reduced the distance if you're really bad at braking. Don't remember what car they used for the test though.

Oh man I got called a moron because I claimed NON ABS gave shorter brake distance than ABS ACTIVE...Now I can correct the real moron. Thank you WYATT🤘🤘👍🇨🇦

Why did you remove the head restraints from the seats?

Anti lock brakes are dangerous. Just throw some loose gravel and a few small bumps in your little brake zone and in a must stop scenario the abs will let go of the brakes and you will have a rear end collision when you would have otherwise just skid to a stop.

I am driving Non ABS car then now i can feel the point where my tyres going to slip. it says upto 10% slip is useful to decelerate quickly.

Go and do a test where you just completely lock the tires, representing a complete loss of traction... like how far will a car slide if it loses control n starts spinning?

ABS is like backwards TC. It activates once an ERROR occurs. A skilled attentive driver can make adjustments before error correction is necessary. Fighter jets eclipse the ability of a pilot, necessitating fly by wire stabilisation. Your body has stabilization mechanisms as well. ABS would be better with more AI. AIBS

i dont think you needed to admit you were on public roads

I'd like to have seen 4wd with ABS and see where that puts the car. I personally like ABS as a safety net when threshold braking in case I go too far on the brake pressure. Ideally, I should just get better are it 😂

So you have to pull an ABS fuse, put it into 4 wheel drive, and only drive in a straight line to gain around .5 second 50-0 mph braking.

My 2020 tacoma doesn't let me drift around in the snow, is there a fuse for that?

Were you threshold braking?

So how do you know that proportioning of brake pressure is correct, 1. with abs unit still installed, vs. not installed and 2. That pulling fuses does not also disconnect capacity for rear brakes to receive braking pressure? Just saying. That'd be a real test. Reasoning; since fronts locked up, you did not feel rears working; then in 4wd, rears DID work, via driveline connection, where rear wheels were effectively braked through driveline connected to fronts; seems rear brakes themselves never did actually become applied in any of the "fuse removed" tests. Right?

- Braking distance done by stopwatch in drivers hands - No test of ABS in 4WD - No description of brake temps/times between tests You're almost there though.

I think it's not the time that matters but handling while hard braking with ABS. 5:01 look how the car started to skid without ABS. I'd go with +0.5sec to full stop time and good handling with ABS

Watch the Engineering Explained video on ABS vs threshold braking

4WD with ABS?

The best test equipment the rally school owns is a dollar store stopwatch?

I like the test, but doesn't it brake better as the tires/brakes get hotter? Of course it goes down the drain once once it gets overly hot, but I'm thinking this was just enough to get the tires/brakes warm enough for a better performance without overdoing it.I like your content and it's not meant as trolling, but I'm wondering how it would've worked out if you started with abs off (brakes/tires cold for those 3 tries) and then turned it off.

So why to rally drivers discount the ABS on FWD and RWD car if its worse unless you have 4WD?

Is it true mid/rear engine cars need more rear brake bias??

what about in a front engine front wheel drive?

Why no headrest?

ok. now do it again while panic-braking with locked tyres. You know... the usecase it is actually SUPPOSED to help in. And how 99% of drivers react in a panic. ABS is not to help racedrivers. It is to prevent actuall accidents.

So probably turning off abs in my fwd car would not shorten brake distance.

AWD vs FWD braking?

Can't we still threshold brake with the ABS still on???

My ABS censor is gone but I don't care. It feels like my old commodore now

I could watch this dude explain how to tie a shoe

Abs vs no Abs Tinder matching test

You needed ABS on and 4 wheel drive on for a better comparison.

My 03 eclipse doesn’t have abs and I can stop on a dime no matter the conditions

Yeah I’ll let my abs do the work, you can also built your technique to brake before abs kicks in

There's recently been alot of pauses and cuts between Wyatt talking. Nothing major, but a slight annoyance.

A lot of this can depend on the calibration of the ABS. I have been in some vehicles where the ABS calibration is horsepoop, and others where it was actually quite good. You had rear brakes in the non-abs test, but the brake bias is almost always towards the front in such a way that it ensures no rear wheel lockup as a "safety" feature. It is a lawsuit waiting to happen if the ass end comes around in hard braking maneuvers. The vast majority of vehicle owners have no idea how to handle a car in anything but normal driving on dry pavement, thus they are built to accommodate them. Traction control gets people stuck all the time. When the manufacturers build a vehicle and they find out that the ass end kicks out during hard cornering, they will change the wheel alignment specifications for less front wheel traction during the maneuver. There is a reason that race cars aren't using the stability control and ABS, etc and it is because a human driver can still outperform the most advanced electronic vehicle controls.

So pretty much you lose back brakes if the wiring for the ABS fuses short circuits while you're driving. I'm never buying a new car lol.

I have two Acura Integra cars. One with ABS and one without. As long as you do not turn ( or have to avoid an obstacle )both are not that far apart but ABS does do better. But ....for turning while braking...ABS wins all day. Complete control of the car. Non ABS....AGGHHHHHHH! SHIT!

But what would have happened if the abs and 4wd were both on? I imagine better braking times too..

Give me euro cars and suspension, those yankmobiles are terrible at stopping.
