Designing The Ultimate Cyberpunk Suspension - Kinematics

Project 66 is where I am making the car "type 66 hoon" from cyberpunk 2077 in real life. This time I am making an optimization algorithm to design the suspension hardpoints.

[@Project66Hoon]

Calling all automotive engineers / manufacturers! I want to interview you! There are still many unknowns to me about the process of engineering a car from scratch. If you know anything about the process of designing a car, how any particular part of a car is designed or manufactured, I would love to talk to you. Please feel free to reach out to me. If you want to speak directly to me, please send me a message through discord (in the description) or my email (in the channel's about section). I want to learn, and I want to share that knowledge with all of those who watch my videos.

[@grantlauzon5237]

I'm sure you've already checked, but make sure your model has space for 6in of vertical suspension travel with the wheels on and steering. Many video games either have the wheels clip through fenders or they animate the wheels steering less than the physics would imply (Forza and GTA V do this (haven't played Cyberpunk)). Forza 1 didn't fake the visuals and on LMP cars you could steer through the inner part of the car because all cars in Forza have the same steering lock.

[@Project66Hoon]

@@grantlauzon5237 I'm making sure of that. Thanks for the suggestion though!

[@Pillow_Princess]

You should get in contact with Burning Wrenches here on KZbin. Pretty sure that mad lad could give you some tips on building a Quadra since he's building one himself. He seems to be mostly focused on the aesthetics and body-design of a Quadra and not so much the actual performance of it, but I'd wager he's THE expert if you want your Quadra to look like a Quadra.

[@BrakeForLoop]

Street Bandito might have some connections. They made a carbon fiber EV based on a 240Z.

[@TheWisdom3]

Superfastmatt just build an offroad dodge viper,. He made his own suspension.

[@stealther1401]

More info learnt in 60 minutes (kept pausing and taking notes) than years of education... some serious vehicle suspension insights gained here. Came for the hoon, left feeling like a new man.

[@Project66Hoon]

Be sure to check out RACE's website too, which is where I learned most of this. They have been super helpful in this process.

[@BatPoopBatPoopBatPoop]

You must’ve not been paying attention in school lil bro, unless ur talking about highschool which doesn’t count

[@x1l3f86]

Wait? Calculus? Beautiful plots? Great engineering explanation? AND Cyberpunk 2077??? Dude I'm in love! Nice work!

[@mennonis]

ok I might have underestimated how complex automotive engineering is

[@user-mn8lz7gf6d]

and this is just one type of suspension...

[@m_remon]

This went from automotive engineering to CS in an instant, luckily for me I love both. Great work

[@stratos2]

It is so cool to see someone take a proper engineering approach to building a project car instead of just guessing and hoping. It being the quadra 66 from cyberpunk makes it even more awesome, though I would have loved to see one of the street going versions. Either way, I'm instantly subscribed, and I hope to see this car in reality at some point in time. it is awesome! Not to mention the super well explained and illustrated video with open source code. A little side note perhaps, if you try to push yourself to be better with every video, that is commendable, but at some point youtube will no longer give you the same growth as a rewards for said effort. Be careful about burnout, your current video quality is already extremely good.

[@Project66Hoon]

Thank you! Oh, don't worry, there will be plenty of guessing and hoping. It will just be educated guessing and hoping. I am quite aware of burnout, so I take brakes when needed, which is part of why this video took so long. Plus, I want to post videos that I can be proud of.

[@gwendante]

Dude, that a project and a half right there. I wish you good luck!

[@este_marco]

i am SO glad that some gamer kids grew up into engineers. you gain a sub bc this is awesome!

[@tjpprojects7192]

The best cyberpunk vehicle suspension is from the Bungie Era Halo Warthogs. It was so beautiful, but 343 had to make the suspension, "mOrE rEaLiStiC" in a SCIENCE FICTION game. All four tires had independant drive, steering, and levered suspension, and it was glorious. It looked really cool the way it worked. I really hate how 343 butchered Halo.

[@Hawk7886]

The original game engine used only springs and spheres. It was fairly simplistic, but it sure was fun.

[@evanlane1690]

Excellent project! This has a great mix of technical knowledge, production quality and cool factor. It's going to blow up as long as you keep posting!

[@iLOLZU42]

This is such a cool and informative project, very excited to see where you go and to learn as well!

[@smeltysmelty8419]

This video had insane amount of detail! I have never seen explanation of the process on the project as clear as here. Keep it up!

[@dasphantom0439]

Dude, I'm in love. Automotive engineering and CS with awesome visuals and easy to follow explanations. Great work!

[@jovanfragosa07]

Had to subscribe! The amount of work put into the video and how relatively easy to digest the information is amazing. So happy you popped up in my recommended!

[@casiquekibra]

I'm completely blown away. Impressive video! Learned so much

[@ashernelson7654]

This is a super cool project, and really well thought out!! Cannot wait to see you develop further :)

[@flameofphoenix5998]

Man how do you only have 354 (sorry 355 now, i pressed a button) subscribers? This video is beautifully made and scripted and you clearly know a *lot* about these topics. Happy to come along on this ride (pun fully intended)

[@LossBH]

this is so damn cool. great video, great graphics as well. made it really easy to follow and understand explanations. loved it!

[@sepehrbagheri2963]

This is one of the greatest times I've spent on KZbin. Thank you so much for the content. Please keep them coming

[@CyberDunk2077]

This channel is going to blow up! After 10 minutes of watching I subscribed. The video was so good and engaging I thought it was an already established KZbinr, then saw how many subscribers you got… I learned a lot from this video and I look forward to watching more of your content, keep up the good work!.

[@thetitus3137]

This is awesome. Building a car from cyberpunk is something I've been wanting to do for years now but have had no idea where to even begin. It's great to see someone else getting a head start on things!

[@Diplomkeks]

I will definitely follow along! I really liked the explanations of the different suspension KPIs.

[@liquighost7988]

very neat project, I'm excited to see where you go with it.

[@_Escaflowne_]

Didn't expect to learn so much about machine learning in a car suspension video. Very cool project, I wish you good luck.

[@maxreyes8494]

Wow, didn't know I was working with a genius!!! Nice work, SS!

[@ThatThrowAwayAccount-tz8ly]

Man I love this kinda stuff, people making cars from scratch and going into all the nitty gritty technicalities + it’s rather educational and I learn a lot. Definitely earned a sub, wish I could sub more then once :D

[@hyrumdetton12]

this is HYPE. I'm excited to see this project progress!

[@you_just]

lovely application of gradient descent! great engineering work!

[@leolehane9988]

this video is a huge step in quality from the last, you should fee proud of yourself! keep at this project, I'd love to see what comes of it. I myself have a few projects going with making custom vehicles, but mine are still in concept.

[@sjorsikdus]

very exited to see the result of this great endeavour! you earned a sub ;) a bit theory heavy but all of that clearly explained in 18 minutes? i'm impressed

[@Skillnoob_]

Great video! I'm very interested in the project and the explanations in the video are really good.

[@runsomeware]

yooo thats the most complete suspension explanation ive ever heard! thank you!

[@Pauglin]

This is very cool. Watched all your videos and I wish you luck with the project.

[@hugomazeas4297]

video quality stepped up! Animations were awesome too

[@bArda26]

that's pretty nice video with nice animations!

[@NIXO3D]

Awesome project! Well done, I'm impressed. Cyberpunk has also inspired me to build things. I'm currently working on a robotic idea that popped into my head thanks to Cyberpunk. I haven't played the game, but the concept of its world and all the inspiring ideas it contains give me so many cool robotic concepts. I've definitely subscribed and joined your discord to follow your project. Keep going! 👏🏽👍🏽

[@mumblety]

Love the quality of this video!

[@kokonut5]

KZbin took 2 weeks to recommend me this gem. Kudos for the great video! Subbed

[@gibby3820]

This itched my brain on all my fronts, thank you

[@realchiefyt-envtuber9903]

I would love to see this driving and possible get to drive it. I am a huge fan of cyberpunk and have had plans of building this vehicle myself. Much luck to you and I hope that we get more on the project!

eyo what, this is so cool! i really hope your project succeeds!

[@serialten]

Your video reached a suspension designer. awesome 🤠

[@harry1010]

computational optimisation?! in my car video?! Brilliant! Well done!

[@zackdexter8285]

after watching countless videos, I gotta say that you won for giving a "proper" explanation. even if it might only be scratching the surface, and even if you explained it all in the most simple way possible (you sounded like you were, or maybe you were just that good at explaining), you said more than most have/ever will!! congrats! I hope to see your channel grow

[@Project66Hoon]

Exactly what I was going for. Thanks!

[@puntloosPD]

this is going to be alot of fun

[@amazin7006]

Top quality content from such a small channel, amazing stuff. You're like superfastmatt with maxed up int and lowered chr 😂

Now that was an engineering masterclass! Modeling, simulating, calculus, algorithms… Congrats dude, takes me back to university years😂❤

[@not_a_therapist]

augh, everything about this is so good.

[@spencertaylor5836]

I have plenty of experience with kinematics from my formula student team. With that in mind I was being nitpicky during the kinematics portion. The optimization portion was completely different, and I learned a ton. This is a great video and I hope to see you succeed in this project.

[@infinitysmp1710]

great video man

[@domovoi_0]

Godlike. Love and blessings!

[@HorizonSniper__]

Oh, another Cyberpunk car being built IRL, that's so cool!

[@pacukluka]

Damn wasnt expecting great explanations on loss function design and the random direction trick for gradient descent

[@Extner4]

Wow. I never knew such complicated engeneering went into the suspension alone... This is epic.

[@GunslingerP]

Thank you algorithm for bringing me this absolute GEM of a channel! I have been thinking of doing something similar to this but instead converting an old Alfa Romeo to electric as a restomod project. I also would love to get sounds working through AngeTheGreat’s engine simulator.

[@Pro88teC]

Okay iam hooked. Take my subscription.

[@nostamine2567]

There is absolutely no way you know alll this without being a fellow FSAE suspension dude like me ... literally no one else knows this stuff , besides a few guys that build drift cars and make their own suspension kits !!!! But nevertheless ... absolutely STUNING video !!! Also the "AI" values figuring method is cool , but u can always go with conventional methods , like choose the Caster 7deg like the most similar car to yours has , then tune the KPI to output the maximum Camber, at full turn, your tyre allows in the spec sheet etc etc , same with the bump steer , u just have to make it colliniar from front view with the top and lower A arms . And you will see ,that if u go deeper into the Anti Roll and Anti Squat geometries the A arm points will actually be super easy to find . BUT !!! U can put as much math as u want in this , the suspension design ALWAYS go hand in hand with the drivers needs , ALWAYS , if the driver says it should be more stable , u increase the caster or trail without thinking twice .

[@anton.1101]

this is damn stupendous!!

[@xXDoUbLeDDXx38]

Man you better take this thing to SEMA after all the work you've put into it, this is a work of art. I guarantee you'll get a ton of love there.

[@Project66Hoon]

I think I might just do that

[@otdoxnite]

yo man good luck with that

Knowledge overload... Keep processing! bib bob...

[@BlaseAnDerHand]

great job

[@Ryzard]

Brother, I clicked this thinking it would be like... Designing it in blender, or modding it into another game like corsa. WHAT AM I WATCHING GOOD GOD!

[@JTCF]

These illustrations heavily remind me of a game called Dream Car 3D, it was a tech demo game where you could build a car using points and links, with suspension and steering needing to be modeled.

[@Robin_the_owl]

the only car i would want to see from cyberpunk in reallife would be the caliborn that thing is a beauty!

[@garbearfar1394]

I literally had the exact same idea to build a type 66, I know nothing of car design or anything relating to cars but really want to learn and the thing I figured would be the biggest hurdle is the front suspension, but its such a major part of the design it wouldn't be right to leave it out XD

[@jame358]

the expansion of the list at 8:57 gave me a heart attack. god damn.

[@novapuck703]

this reminds me a lot of project octane being made by "Mega Dookie" (I know a great name). Can't wait to see this as it develops :)

[@Javierm0n0]

I'm very interested in seeing how you end up changing your loss function when you get into real world testing. I hope you will be able to show the difference between your final function and your initial function so i'm definitely subbing. Fantastic project you've set forth here.

[@Project66Hoon]

Thank you! I've already got a few suggestions that I am going to apply.

[@Javierm0n0]

@@Project66Hoon also for the headlights, you could make the outer sides of the front grill-cover thing a smoke finish, which is usually a clear coat of paint over a light lens with a little bit of black paint mixed in. Searching smoked headlights can give you some good references for the efficacy.

[@AsthmaQueen]

I know the Celica used a unique suspension to try and deal with camber issues when going over bumps but had extra moving parts that needed maintenance

i hope you will look in to this type : from Citroen - Wikipedia Hydropneumatic suspension is a type of motor vehicle suspension system, designed by Paul Magès, invented by Citroën, and fitted to Citroën cars. The suspension was referred to as Suspension oléopneumatique in early literature, pointing to oil and air as its main components.
