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.
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.
@@grantlauzon5237 I'm making sure of that. Thanks for the suggestion though!
You should get in contact with Burning Wrenches here on UA-cam. 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.
Street Bandito might have some connections. They made a carbon fiber EV based on a 240Z.
Superfastmatt just build an offroad dodge viper,. He made his own suspension.
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.
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.
You must’ve not been paying attention in school lil bro, unless ur talking about highschool which doesn’t count
Wait? Calculus? Beautiful plots? Great engineering explanation? AND Cyberpunk 2077??? Dude I'm in love! Nice work!
ok I might have underestimated how complex automotive engineering is
and this is just one type of suspension...
This went from automotive engineering to CS in an instant, luckily for me I love both. Great work
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.
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.
Bethesda could never
@@hakijin 16 times the detail
Dude, that a project and a half right there. I wish you good luck!
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.
The original game engine used only springs and spheres. It was fairly simplistic, but it sure was fun.
i am SO glad that some gamer kids grew up into engineers. you gain a sub bc this is awesome!
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 UA-camr, 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!.
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)
Didn't expect to learn so much about machine learning in a car suspension video. Very cool project, I wish you good luck.
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!
Dude, I'm in love. Automotive engineering and CS with awesome visuals and easy to follow explanations. Great work!
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!
Wow, didn't know I was working with a genius!!! Nice work, SS!
Now that was an engineering masterclass!
Modeling, simulating, calculus, algorithms…
Congrats dude, takes me back to university years😂❤
Didn’t think I was going to learn about machine learning in an automotive engineering video, awesome stuff
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
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
Exactly what I was going for. Thanks!
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!
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!
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.
This is such a cool and informative project, very excited to see where you go and to learn as well!
This is a super cool project, and really well thought out!! Cannot wait to see you develop further :)
this is so damn cool. great video, great graphics as well. made it really easy to follow and understand explanations. loved it!
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
super informative video, really hope this channel blows up.
UA-cam took 2 weeks to recommend me this gem. Kudos for the great video! Subbed
I'm completely blown away. Impressive video! Learned so much
I will definitely follow along! I really liked the explanations of the different suspension KPIs.
Your video reached a suspension designer. awesome 🤠
lovely application of gradient descent! great engineering work!
This is very cool. Watched all your videos and I wish you luck with the project.
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! 👏🏽👍🏽
very neat project, I'm excited to see where you go with it.
yooo thats the most complete suspension explanation ive ever heard! thank you!
That's an awesome project with beautiful explanations ❤
Oh, another Cyberpunk car being built IRL, that's so cool!
All hail the youtube algorithm! Found your channel at random, and insta-subbed. Nova presentation, choom! Good luck with your project!
this is HYPE. I'm excited to see this project progress!
video quality stepped up! Animations were awesome too
Love the quality of this video!
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!
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.
insane thank you so much for all this nice and condensed knowledge ! 🤯
This itched my brain on all my fronts, thank you
eyo what, this is so cool! i really hope your project succeeds!
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.
I think I might just do that
that's pretty nice video with nice animations!
Damn wasnt expecting great explanations on loss function design and the random direction trick for gradient descent
Top quality content from such a small channel, amazing stuff. You're like superfastmatt with maxed up int and lowered chr 😂
Great video I’m really looking forward to your new videos
augh, everything about this is so good.
the expansion of the list at 8:57 gave me a heart attack. god damn.
this is going to be alot of fun
the only car i would want to see from cyberpunk in reallife would be the caliborn that thing is a beauty!
Wow. I never knew such complicated engeneering went into the suspension alone... This is epic.
great video man
Godlike.
Love and blessings!
Wow... ammout of knoledge is huuuge! Instant sub!
this is damn stupendous!!
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.
This is top tier!
Awesome stuff
Me 1 year ago trying to make a physics-based car in Roblox and wikipedia-studying Ackerman geometry, caster angle, king pin angle, scrub angle, tie rod/bump steer stuff, mounting points, types of suspension, and thinking I can't be surprised coming in...
Left with 5 times more stuffs to learn, 3 programs to try out and humbled 😅
also wanted to say to not change the thumbnail, it's perfect
Your channel just got recommended today, love the content. Have you decided on fabricating or finding a chassis yet?
I'm going to fabricate one
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.
Thank you! I've already got a few suggestions that I am going to apply.
@@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.
yo man good luck with that
OH MY GOD!!!!
Another youtuber is making cyberpunk car irl?!?
Yessss 🎉 I'm watching how burning wrenches is building quadra vtec. It's so amazing to have another youtuber make a car from the game ❤ subscirbed!
yep, would also be amazing to see them both side to side when finished. although, the conception of project 66 seems more lengthy
great job
The red pixel that's dead in your hair makes me smile but I literally can't look at anything else while it's on screen lmao.
Lol, I bought a broken $60 DSLR camera off Facebook marketplace that I fixed, so I call it worth it.
I realy would like to see a real life quadra, hope you will have the motivation to achieve this project
so freaking cool
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 :)
I was like 10 secs in and subscribed
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.
I had not the slightest clue on how many aspects there are to just the steering and suspension dynamics of a car
Hey i would love to see highlights in the grafic in releation to your explentaion. for example make the kinpin glow up while u talk about the kingpin
Amazing video will definitely be following this project! Can i ask, which software did you use to create all the videos showing different suspensions and graphs
Thanks! It's called motion canvas.
Knowledge overload... Keep processing! bib bob...
Keep going 😍
I bearly even play Cyberpunk, i dont know shit about cars and my knowledge of maths definitely isnt at this level but damn this was a great video, nice work :)
this is cool
For the love of god.. Love the project .. some points though:
1) its suspension geometry. Not Key performance indicators. [at minimum suspension performance] KPI is the acronym for King Pin Inclination, an incline being an angle. , You will get confused. stop it.
2) Hooning is drifiting and sliding.. acting like a hooligan. Understeer is a drivers nightmare. understeer is designed for normal passenger cars, because of insurance companies and crash safety. the hooligan does not care. Most of you have been drifting since mario kart. Even in front wheel drive cars.
3) ackermann steering exists because of different turning radii. the fastest cars have, oversteer bias to strain the tyre more and gain more yaw accross the rear axle. (aka strain based rear steer)
3b) negative ackerman is put on high aero cars, like F1 or Indiecar, you are building a street brick. negative ackerman is not going to help you here.
4) wow, caster angle actively means almost nothing, when not inrelation trailing length. because as so many people get wrong. negative trail is unstable. you can have any angle to facilitate that.
5) Please look up other cyberpunk cars. Other people are building stuff.
Excellent video. One of (if not the) most indepth videos on important suspension variables. Having designed a suspension system for a FSAE car myself, I appreciate an indepth suspension video.
My main complaint is that you didn't cover all of the other inputs and the relationships between them. Hopefully that will be the next video. :)
The biggest question I had on the video was why you weren't using the outputs as inputs? Starting with the suspension nodes as inputs and calculating the caster, camber, etc, as outputs sounds backwards and arduous. I'm not saying it's not possible, just inefficient. All of the variables you covered indepth can easily be made inputs when CADing the suspension.
Provided the software can handle underdefined wire scetches.
Thank you!
I decided to not do more of the kinematic KPIs as it would have turned into a very long video which I feel most people would not want to watch, so I tried to strike a balance of being in-depth while being brief. For those who are rally interested and want to learn more, there is RACE's website. I will be covering some of the dynamic KPIs in the dynamics video.
I didn't make the KPIs the input because some of them directly contradict each other, and some of them are so related that it would be difficult to know how to set it. I can set some of the KPIs to what I want right off the bat though, so I can start from a pretty favorable position and then go from there. Also, RACE doesn't accept KPIs as inputs, just the hardpoint locations.
I thought I knew like 70-80% of how suspension is designed, as my classes had already covered camber, caster, toe, etc, I did not realize how deep it was and now I'm questioning my decision on building my own car lol
Suspension lore vs gameplay
this brings me back to FSAE
Big W please add a build plan when you are done lol
This is going to be fucking fun. Lets go.
I do ground up car fab. This is a very very brave project even if you have a lot of experience building cars. And I'm usually the one people call nuts for taking on wild projects.
This is insane. Keep up the good work man. Only question in my mind, is why electric? I havent played cyberpunk in ages, so i cant remember if its electric in game, but kind of seems a waste to me.
I surprised you haven’t used the Super Strut setup (Toyota celica GT4) being a hybrid of MacPherson struts and multi-link it will eliminate most of the compromises at the cost of being a little more complicated (although this already looks over complicated).
Great video and I look forward to following your progress.
If you want the car to emulate the hoon irl in handling, then you want it to have oversteer. The car is based on Ken Block's Hoonigan drift car, and the car in the game is very drifty.
Starting out, I want the car to be very safe as I am not accustomed to drifting cars. However, as I get more comfortable with it, I can change it to something that is more likely to drift.
I'm not sure if you're checking comments on older videos so I figured I'd post here. Also not sure how much you have figured out since then so I apologize if any of this is old news.
Windshields are made of laminated glass. Basically two sheets of glass with a plastic layer between them. Side windows and rear windshields are typically tempered glass though are often replaced with lexan or some sort of polycarbonate in racing applications.
If you're interested in odd door mechanisms, look no further than Koenigsegg and their "dihedral synchro-helix" design. It's not exactly what you're looking for, but maybe you could find a way to adapt it for your purposes.
Combining powertrain and tire size, you likely do not want a super wide tire if you want to daily drive it. You'll lose a lot to mechanical drag unnecessarily.
When it comes to wheels, would you consider some retro turbo fans like 80s Audi racecars? Otherwise, would it be possible to just buy a deeply dished wheel and make hubcaps that matched?
Lastly, I know of some books and resources that are racing specific, but I'll let you decide if they fit your needs.

I do read all comments, but thanks for making sure I saw it!
I'm likely going to use lexan for the windows.
I may be incorporating the koenigsegg doors into this, I still have to figure that out.
I may make the front tire narrower, still TBD.
I am planning to make custom plastic inserts for the wheels to make it look as close to in-game as possible.
I've read some of those books, but I'll check out the others!
13:53 This graphic is known as a "Lumpy Spiderman Plot".
If you build a sporty car (which you are), you want to have quite high castor trail. It will make the steering wheel harder to turn (which you do not care about), but it will increase high speed stability without. sacrificing maneuvrabilty
Feedback received
Very good explaination of suspension dynamics and optimization methods. I've had college professors in my master's program who didn't do as well. After doing some design work for large off-highway equipment, I feel your pain about not being able to design BEFORE you order parts. Where's the vendor CAD?
I have repeatedly wished for a website like McMaster but for all car parts. It would be so nice.
You should check out this game called dream Car Builder, It allows you to build and design frames, suspension, and steering systems using a softbody physics simulation. It seems like it would be a great way to visualize these concepts further, as you can actually drive the car you build. The game is 10$, but is worth every penny in my opinion. Its also just a fun engineering sandbox.
I'll check it out!
