I love how it doesn’t have some loud obnoxious music, but instead is literally just the sound of it being built.

This is simultaneously the coolest and most ridiculously over engineered thing I’ve ever seen anyone build out of Lego

As a tank enthusiast it was really interesting to watch you encounter and slowly develop all the crucial parts of a tank track system. Track tensioner, return/idler wheels, guide teeth. That's my favorite part of your videos: the troubleshooting.

Love literally everything about this. Favorite part is learning about the different types of suspensions and how they react. I can’t see how you can make your content any better. I love how there’s no music it’s all just the sounds of the legos themselves. I immediately love your content and can’t wait to see what else you have!!!

I actually find it so interesting as to how he just..... Makes these machines. Cars. Whatever you prompt him, with enough time, you'll have it tested to perfection by him.

As a vehicle mechanic, I can safely say this is a fairly accurate representation of how these suspension types act on real vehicles. I like how the bump steer and camber / toe angle changes are exaggerated during suspension jounce and rebound. This would be a great teaching tool for apprentices in trade school

17:16 reminds me of school busses, in the front is “op, did we hit a bump?” In the back it’s “DEAR LAWD DID WE HIT A JUMP!?!?!”

I'm amazed at how accurately you've recreated the road just outside my house

Nice contraption, you should make a car with pneumatic suspension, using those small transparent blue Lego pneumatic cylinders. If I remember correctly, they have very low friction. Also you can use them as shock absorbers, pairing them with normal Lego shocks and connecting their inlet to their outlet directly with a short tube, so they basically work as real ones. And you can make a hose-pinching system that allows you to control the airflow through the tube, as in switchless Lego pneumatic compressors.

I love that instead of simply removing links to tighten up the belt, you engineered an extremely complex and dynamic workaround. Great job, I sure wouldn't have thought of that!

2:35 "Alright guys i did some off-camera grinding" really great video tho lmao

This is incredible. I can't imagine how long it took you to research, build, record, and edit all of this together. Amazing

Would love to see a comparison to a verhicle with NO suspension at all. Because this still looks quite rough to a vehicle layman such as me, but I imagine no suspension would just break the vehicle or simply not work at all. But at least then we'd have a reference , a 'base line' to compare the other suspensions to. Great work. Love this format; all of the complexity and entertainment value is in the builds itself - this doesn't require flashy editing, annoying music or narration. Very refreshing compared to most channels.

I spent countless hours of Lego building with my two sons and I can’t wait to do it again with my grandkids!

13:00 Man, I *FELT* those bumps in my _back_

19:36 Samir, you're wrecking the car!!

I'd love to see more types of suspension, maybe ones from f1 cars or those from trophy trucks, see how they compare to these daily driver type suspension

I love that you show how you improve stuff not just the finished models. And that audio is just satisfying.

2:20 really liked that mechanism with use of linear actuators

Even before getting to the car, it’s already amazing watching you build the suspension test system. Good job!

I normally can't stand ASMR-type things. but being an avid LEGO fan since childhood. the sound of the bricks and technic pieces being put together brings so much satisfaction and nostalgia.

Probably my favorite part of this channel is how they show the complications and issues in the process of building, then (quite literally) build a solution to the problem, instead of cutting out any imperfections entirely. Lovely how they keep the realism and show that there's always a workaround ^^

12:49 Lego equivalent of the irresponsible dad from happy wheels

It's fascinating just how close to reality you can get with some plastic bricks! And the imitation of the leaf springs was spot on, lots of jumping

10:07 : "Cons: wheel camber" *You have provoked a gang war*

i`d be very interested in a second part, where you test other more modern forms of suspension. e.g. phneumatic or with a shock absorber etc.

Oh this was amazing to watch, the tuck suspenison hold out so good. would love to see the Citroen 2CV suspension on this test rig (with the front and rear suspension connection system)

I would love to see this setup with actual fluid filled shocks and scaled weight, like an RC trophy truck or something. It's jarring how much bounce there is in the lego "shock"

This is very fun to watch, and it's a great way to show how exactly the different suspension types used work. This is something I could watch over and over again.

The VW beetle front suspension was so interesting, we are so used to seeing the two arms perpendicular to the wheel, these are parallel

This stuff brings me back to my childhood, when me, my father, and my two brothers had this whole little town set up. We had a house for each of our lego characters, and we kinda played it like it was a DnD game, just without the dice. We used to come up with stuff our characters had to try to get done and everything..... Now, these videos make me want to repair my raspberry pi and get one of those NXT things with all the sensors and such. Screw it, I'm almost 30 and I still play with legos and I am not ashamed lmao .... this also gives me horrible flashbacks of dealing woth conveyor belts on a packaging line... haha

This guy's living the life I wanted as a kid.

00:00 Suspension Test Station 05:49 Stop Button & Speed Computer 06:43 MacPherson Strut 07:21 Semi-independent Rear Suspension 08:20 Beetle Chassis 10:17 Torque Tube 11:10 Leaf Spring Suspension 12:45 Testing Suspension Systems 18:51 High Speed Test

In the first bit I absolutely loved the way your track wasn't right so you show the entire process of redesigning your build and other mistake along the way just to overcome a simple problem, very cool stuff

That high speed test is genuinely one of the funniest things I've ever seen, that had me in tears 😭

I Love the sound of lego bricks being placed

This is amazing. Also nice to see how the front tires usually drive over all the stuff while it seems like the rear tires often collide with the bumps and shock the whole chassi

I wonder how an official lego set performs on this testbench. Like the Land Rover Defender or the F150 Raptor!

No music, no fake personality, this person gets it, just show us what we want

The engineer in me was so happy when he didn’t stretch the track, he built a tensioner. Beautiful.

10:52 didn't even know it from cars before, man Legos are so helpful to understand

13:08 was hella trippy. I thought you were doing some crazy camera work for a second there.,

This guy has every single piece I ever needed 😅

18:07 in trucks, the robustness of the axles often transmits shock to the nearest weak links--the ball joints and wheel bearings. Amazing that you managed to simulate that

I don’t know who is more impressive; the engeeniery behind all the suspension system or the threadmill by itself, both of them are awesome

15:08 Volkswagen- Das Auto

Didn't come to this video expecting a lesson in common suspension types, their strengths, and weaknesses over the the past few decades, but here we are! Delightful.

Literally the only asmr that I can not only listen to, but enjoy and not feel the need to punch people in the face.

"both sides are now synchronized" And that's a sub. See ya at 100k!

This brings back childhood memories from 45-50 years ago. I used rubber band as springing medium and Lego Technic didn't exist yet. Great fun, great video!

As a suspension engineer, this made me happy.

With all those clicks and clacks, the sound of this video is so damn satisfying and soothing

I love the detail and thought you put into the suspension designs tested! I would like to see how a Double Wishbone suspension would perform in this rig.

15:24 sTaNCe bRo!

Great that you display the iterative design and build process. Super fun to watch and helps to understand how to approach engineering problems.

Lego Technic looks a lot more inspiring and it gets you to like solve Mechanical Engineering Problems such as all of this, For example: - Tester Too loose - Breaks all the time due to a misplaced piece - Hearing a weird noise while running it - Conveyor breaks all the time due to a contacting piece - Anything you put on the conveyor doesn’t fit under the conveyor Those problems are kind of common and it’s like a mind testing thing to learn of mechanical engineering to fix them, Once you learn to make machines like this guy does. The best part of this video was the sounds because it’s so satisfying

Absolutely awesome! Well done. Just one thing I noticed the beetle chassis had a great amount of bump steer at the front, the outer steering tie rod ball joints needed to be lower on the spindle/hub assembly, this would have stopped the bump steer. Great video!

It would be so neat to see a Trabant suspension system, it uses transverse leaf springs front and rear

I love that even the errors are shown alongside the solutions. Engineering isn’t just about finding an answer, it’s a process.

Would love to see a pushrod and double wishbone too! Maybe a solid axle coil to compare to the solid axle leafspring

This was so much more interesting and entertaining than I thought it was going to be. Great work showing off some engineering with legos

One of the most beautiful things about driving RC Buggys Offroad, was always seeing the suspension doing its thing & working hard to keep the ride smooth! nice video!

Aw he knows what I want in this video, that ASMR noise of plastic parts snapping together. Gimmer me of that.

This is extremely cool. I think the best part is the way you've filmed this, each shot has the faint 'click' of lego joining lego, it's really something. Great job.

It seems hilarious to me that when running over the thicker bricks (would probably sound funnier if I knew the name for them), it simulates a Lego person being run over lol

It would be cool to see what effect castor angle would have on Lego suspension, fully independent double wishbone would be interesting too.

That Beetle one takes the cake hands down. It just needs to be tuned for the Chassis weight properly

Lego literally was my life from when I was 7 till 16 years old (I'm 23 now and sold it all). I used to go to conventions but I've never seen something built so well. Incredible!

I was mesmerized, the building process, the clicking of the parts and the level of techinical skill...and the high speed shredding of the chassis to top it off Great work!

This is brilliant! An accelerometer on the seat and you've got yourself a proper test bench!

The sound of Lego coming together is the best ASMR you will ever hear.

Awesome! Definitely explains why going over them speed bumps at higher speeds makes them seem more manageable 😃

I can only imagine how much fun you had doing this… When the first little man fell off and you wrote RIP I burst out laughing… Later you continued to disintegration pretty cool. I'm sure you had a blast thanks for being here

And now, a lot of people are going to understand why Jeep kept the live axle setups for so long 😁 Any chance of mid sixties Chrysler A-body setup? Live axle leaf rear, unequal length control arm front with longitudinal torsion bars on the lower control arm.

One thing you can notice between the different suspension types is how under- or over-damped they are. It seems like the damping is left up to chance, mainly based on the friction of various joints; it's the spring coefficient and sprung mass that is being adjusted in most instances. The combination of mass, spring coefficient, and damping coefficient will result in a different resonance when subjected to a perturbation. If there is too little damping, you see repeated, decaying oscillations, as in the third vehicle (rear leaf spring chassis). If there is too much damping, the suspension doesn't have enough time to compress and the vehicle moves with the bumps, as in the second vehicle (VW beetle chassis). With just the right balance, you see maybe 0.7-1.5 oscillations, such as in the first vehicle (compact cat chassis with weight added). In addition to the damping factor is also the bandwidth or cutoff frequency of the suspension. The suspension acts as a low-pass filter, allowing the vehicle to follow slow changes in height (with some delay) while absorbing and cancelling out fast changes in height. As the speed is increased, you can see how it goes from bouncing a lot and following the bumps, to oscillating over them with a amplitude hopefully less than the amplitude of the bumps themselves. Finally, you see how both amplitude and frequency contribute to the instantaneous force. As the speed is increased, eventually the peak forces are too much and break apart the chassis. Great video. I'm tempted to try to estimate the damping factors and peak forces for the various cases. :)

Steering issue of Beetle suspension was solved in ZAZ-966 and 968. Also in Beetle it was made different - steering consists of 2 triangles with steering box in the middle. Also you can see similar 1936 Cord suspension that eliminates bump-steering. And Citroen 2CV - that eliminates front-back tilting but has a body roll)) Also an interesting alternative to McPherson is Lancia's sliding pillar suspension, which was as well used in Morgan 3-wheeler for decades

19:03 is like mater on the so called "new road" in the first cars movie

I was really surprised the one with leaf springs came off instead of the leaf springs breaking. Really good job with the build design on that one! (I mean, they're all great, and beyond my capability.. but the leaf spring one was the most surprising. It also worked better than I thought it would - which I guess is why large vehicles still use them.)

I love how he displayed the evolution of suspension technology via test/error (most likely what previously manufacturers went through) step by step. Through. Legos. Awesome channels - keep it up!

Dude really…………. This video WAS SO COOL………. I’m an automotive engineer and playing Lego Technic since I’m 5-6 yo (was in 1985-86), you cannot imagine how much I enjoyed your video!!!!!!!!! Especially because I was working on different types of suspensions since I’m around 7-8 yo!!!! This was an absolute fascinating subject to me!! Then transmissions, differentials……… I’m 100% sure you feel me 😄 And I have to say the different suspension systems are so ingeniously transcribed into Lego!!!!! You’re VERY talented, thanks a lot for the video 😃 Big salut from France 🫡🇫🇷!! ViNZ.

Watching how the suspension works was so satisfying! Incredible build!

I love how this video doesn’t have music, music gets annoying after awhile. Good job 👍🏻

fun fact: chrysler's torison bar suspension in the '70s DID have adjustable height/tension from the factory! all you needed was a wrench and a little experience of how much twist affected the height (it needs to be driven around a little to settle in)

The first video I watched of yours gave me the idea that you must be an engineer. This video establishes that as a fact. I really enjoyed watching this one. You have earned a sub.

I don’t know why but this was one of the most enjoyable videos in a while

This really highlights the importance of preload in suspension to be more effective at smoothing bumps. The springs were too stiff for the lighter weight but appropriate for the car with weight added.

I just stumbled on this channel and even though I have no idea what’s going on it’s incredibly satisfying to see the process! The amount of knowledge he has is crazy

14:27, this is smoother than 99% of the roads I drive on in Poland xD

Wow! Amazing machine and amazing test chassis, the "cars" also bounce exactly as a generic car would on a speedbump Great work! And one another thing, if you're reading this... thank you a lot for the very thorough build process so dummies like me get good ideas if they want to build a moc car :)

I am fascinated with every aspect of this video, from the designs and builds of each part of the suspension testing rig to the cars themselves, but I cannot ignore the immense comedic value pf watching those cars being tested on insane amounts of bumps at ridiculous speeds and I was laughing really hard at the end but like... laughing for science 😂

man, the soundscapes of your videos must be official soundtrack of all R&D. i should unpack all my lego... anyway, wife left with all 4 cats, so i can built anything i want now

I love the fact you can see mistakes are made as it's being built, then finds a workaround. I love it.

16:53 damn that's a real car's suspension

Amazing! I like how the VW Bettle is instantly recognisable from it's toe-in/toe-out suspension.

this guy was probably the one kid with all the cool lego stuff that you would never find anywhere else

This dude took 9 different camera angles for a lego car, and I'm glad he did

Watching engineers playing is so satisfying

15:13 how they made the slime sound in minecraft

We all just sitting here watching a dude play with Legos REALLY well, and I think that's awesome
