- Learn on Monday, wrench smarter on Sunday. This week we're learning about a car's chassis: what it does, and how to improve it.
Introducing a NEW series on /DRIVE, aimed at educating you to build a faster, better, more reliable car: /ENGINEERED. We want to empower our fellow enthusiasts to know more, and do more, by learning from some of the best engineers in the game.
I love listening to knowledgeable people talk about their craft.
Very informative drive. Thoroughly enjoying these videos.
I have a rotisserie restoration 95 mustang that I have stitch welded, added Stifflers sub-frame connectors and a rear adjustable strut tower bar ( that I made) and even on the rotisserie you can feel the rigidity added by the welding inside and out on every seam. I also plan on adding the X-brace from the convertible to assist the strut tower brace on the front. I can't wait to drive it...
I didn't know Ben Stiller was a chassis engineer.
+Sal sean you were mistaken about a great many things.
leloodallasmultipass
Is there something wrong with you?
+Francesco Bernoulli ikr it wasn't even a good joke some people are so rude 😑😒
+Sal sean I SEENT IT
+Sal sean I love all the awkward shenanigans that aren't contrived at all that happen while he's cross-bracing
Porsche have an advantage.
The first design the shape, then decide which is the front and which is the rear.
I like this series a lot! Serious information in a nice way explained!
can we get a engineered video on properly tuning turbo engines? how to adjust the blow off valve properly, adjusting the waste gate properly, testing turbocharging systems, how to properly build one etc..???keep up the good work, love these videos
Really enjoying the /ENGINEERED series; very informative, useful information.
This video changed my life, when I saw the knowledge Joe has, it blew my mind and I became hungry. Left my job went to uni studied motorsports. started working as a damper technician and race mechanic. Now im a race engineer for gt4 cars and run a turning company. Get inspired take action! Thank you Joe and Drive you've changed my life
Holy crap man, congrats. That makes me so happy to hear a story like this. Im sure you still have moments when you question wtf you're doing (maybe not), but all and all, it sounds like you're proud of what you're doing. Good on you. If it was soley this vid that inspired you to change course in life, and go back to school, then that is pretty impressive.
Im in a totally different field, but i love engineering and seeing stuff like these vids from a distance. Im mostly happy doing what i do, but i could see myself in another life being a mechanical engineer. For now, i just appreciate it like art and learn about it on a hobby level. I think it's fascinating how clever or simple things can be designed and still get the job done, or be an improvement over existing tech. It's hard to explain why i like it, ill just say, 'there's beauty in simplicity'.
These vids are great, i wish drive still was still more active, they did a lot of great stuff.
The editing/post production person for /DRIVE is one of the best in the business. F/n art, man! Thank him and the person who hired him. :)
strangersound This comment made my day. Thanks!
informative episode. a suggestion is to show a car and the effects on lap times with each mod made on the suspension or chassis.
I like the format but would have like a tie in or follow episode to show the real results on the track so you can see the most return on your racing/mod dollars.
+rjs15570 We have talked about doing that. Comes down to money and scheduling. I would love to explore the difference in lap times between 0 camber and -4 camber, toe in, toe out, etc etc
I could watch these videos for hours.
Brilliant. Can't get enough of these videos.
I never considered how bushings could have an effect on alignment settings such as the camber. I went with hard rubber bushings and the alignment shop said they were so stiff I need to break them in before they can adjust the settings to spec. BBI is top notch, thanks for sharring
This is the content that's really hard to find. More of this please.
I thought these were gonna be lame. Man was I wrong these vids are my new favorite!!!
I take notes when I watch this stuff
Cars lowered on coilovers dont necessarily give better roll center unless you do a roll center correction to get closer to the CoG 9:03
I REALLY like these segments. Keep them coming!
Thank you from the bottom of my heart. The Engineered vidéos capture the beauty of sport mécanics and bring it in an éducational manner.
Ya this is my passion. I used to really be into engines before it kind of turned into "more money = more power". Chassis work is unbelievably wicked. I'd love to really dive into something like that and start building my own parts. :D
So...any discussion on torsional rigidity and lbf/ deg? Elastic modulus of materials? Composites, high carbon steels, and high strength aluminum? High cycle fatigue? Triangulation of structures? FEA modeling? Pickup points and load distribution?
There are some pretty large areas of discussion missing.
+BurnDuration We cant cover everything in one shot. We are waiting for people like you to chime in, so our next round of production can touch upon those subjects. We have to find experts in those fields to interview as well. We are watching and making notes.
+Thaddeus Brown Yup those are exactly the things we want, typical failure modes for a chassis and what to look for while driving to figure it out. Please also do one on damper tuning. Great vids keep em coming.
do you mean what instead of who?
It's called American English.
+Bahajaj Ali no its a movie reference
No not at all im American it should be what insted of who
I was being sarcastic.....okay im out of here.
+Bahajaj Ali Don't bother with these guys. They are peasants who have never seen Kindergarten Cop lol
This series is amazing, I would like to see more of the application and how it looks in a car.
we need more of these stuff
@1.29 damn that boost
enjoying this series to the max... More pls
How about ranking least to most expensive effective suspension mods, or most bang for your dollar. For instance, investing in a stiffer sway bar, strut tower,...full roll cage, etc.
Your episode begs those questions.
+rjs15570 how effective any mod is different for every car.
I love these segments. The LSX engine /Engineered was awesome. keep 'em coming.
I'm really enjoying these videos. Keep it up DRIVE
I love this Engineered series, I'm learning so much lol
I remember arguing with people about Car engineering. people always look down on me about chassis how i always emphasize its one of the part no one care about. Because it cant be really modded. Chassis is what give the real character of the car not the engine. The movement, the handling and how agile is feels come from the source of the chassis. Then the other parts come after like the weight, suspension setup the balance of 50/50 weight distribution.
if you take a look at a cheetah, no matter how powerful their legs are or how light they are, weight are limited to some extent for their size. their tail may add slight weight but it balance their agility. think as their tail is part of the frame.
Who ever drove the NSX and known the history about aryton senna know this really well. And who ever drove Porsche can say its probably the best chassis ever made.
Now about the Shocks? Joey great job. Look forward to working with you.
More of these types of videos please.
strut tower brace is always on my list when I by an older car
most cars now seem pretty stiff... or there is just no room under the hood -_-
awesome vid. I always suggest you do one mod at a time and drive the car a while to feel the change. Doing more than one change at a time means you won't know what did what. This goes for everything including braces and suspension etc etc but even things like tires and alignment adjustments.
im loving this series keep it coming
Great video definitely would want more of these
Awesome segment
is someone a metroid fan? Because one of those logos and the music are very metroid esque... also a neat video lots of interesting points
Thank you for providing us content!!!
I like this new series. Good work.
This is great stuff. Keep them coming!
Thanks for the upload! Need more informative videos like this!
i like this series a lot keep it up!
Whats that song they keep playing on these vids?
I like it ,sounds like chill music.
Ah...now this is the kind of schooling I love.
this series is rather interesting.
Just going off the title, You guys should listen to a song called "Who is your daddy, and what does he do" - Austrian Death Machine
+Oberone Kenobi or you know... Arnold Schwarzenegger
Umm, yeh I get that, you obviously haven't listened.
Without listening I'm guessing it's some kind of metal song inspired by the Arnold line. Just listened. That's exactly what it was.
And it was awesome right :) ?
I will probably never listen to it again.
What's the background music?
I LOVE THE NEW /ENGINEERED VIDEOS!
awesome and helpful video! Thank you +/DRIVE !! What's the name of the music tracks playing in the background when Joey Seeley is speaking?
AWSOME VIDEO just learned a lot.
I love this series! Thank you, Drive.
What you did there...I see it
+100PercentLuck It's not a toomah.
+100PercentLuck Our mommy says that our daddy is a reeeeeeal sex machine...
+100PercentLuck An improved chassis can make the car much more Kimble... I mean Nimble
+leloodallasmultipass Dr Rang can fix it
great informative videos. you guys should make more like these!
Love these engineering series. Keep em coming!
LOVE this series.. keep 'em coming!
Damn, I feel so educated. Cars are so cool.
I love this series!
Seems to me the added stitch welding is for fatigue. Talking Stiffness, it is 1/12. Base*height^3 and modulus.
Love these videos Drive, keep them coming! Can't wait to see one on aerodynamics!
These are great. Keep it up.
How do you improve the roll center with out changing the geometry? Surly strut bars only improve the geometry if the chassis is very floppy? and coil overs don't change the geometry but do bring more control? not trying to be a smart ass but have some questions?
Good but too short!
How much does the development of a new chassis cost? On a car like Audi A8?
That 993 gets me everytime..
Amazing video!
bushing is such a funny word ^^
The passat nms chassis by volkswagon AG is the greatest chassis ever conceived.
Neato. I am doing this to my 1930 model A right now, I am 20...
+B Fuller (Live4theApex) I just wanted to make a point that it doesn't need to be a million dollar Porsche or a race car. Anyone can do this, even some losers who post wise ass remarks on comments for no reason (in case you know any of those people). Furthermore, I have videos of my work so if people were interested, they could go and watch...
Is chassis engineering just trying to get the maximum rigidity out of it under some constraints or is there some degree of flex that is desirable?
EDIT: in the video he says you want the chassis to be nice and stiff, but I read somewhere that for instance the crazy lean angles in MotoGP are due to advances in controlled chassis flex.
Nützliche Karosserietips, danke ;-)
Great video
Soooo, I am a owner of a 2019 2ss camero . I have been experiencing some weird knock in the front of my ride when backing up or turning. I am a female and LOL, I have to take it in tomorrow to dealership , on my report I seen they have it down as my chassis getting worked on. Any kinda of suggestions that could possibly help me out???
The chassis is the top priority when it comes to improving performance of any car. Then suspension, brakes, transmission and engine follow.
+man0z They're not the priority, even though changing them can generate significant performance improvement. But before changing the tires, you have to make sure to exploit your actual tires to the maximum. To do so, it's mostly up to the suspension to bet set & tuned properly, and finally you'll come close or even reach the performance you would have had if you change the tires (to better ones).
+Razvan J Exactly. That's the problem with people, because they only see a car as an engine. Pretty sad...
Best Title Ever
What's the music at 3:20?
My VTEC strut tower bar made me super stiff.
That sharpie pan
does drive+ have more of these?? i'm about to subscribe for +..
This guy was lucky to have learned from Greg Fordahl, as good a driver (google how many SCCA National Autocross titles he won) as chassis tuner. But then when he says "was" Porsche factory engineer and laughs, well if you knew Greg the way he laughs speaks volumes.
Tune at 3:13 ?
All the things he said were obvious; seam weld where you can, throw in a brace for the strut towers.
+Kenshin Ushiroda I'm sure the matter is more complex than he let on. I wished he provided some detail or data about how a lack of rigidity affects alignment. Actual data based on a measure around a course. I imagine that's something a race team would measure (or simulate ie finite element modeling). Of course stiffer is better. But like he said, there is a financial cost to everything and a weight cost also. It would be interesting to know even for budget race cars how to measure or find area that are too low on rigidity. There must be a way. The chassis shaker rig sounds cool, but it sounds $$$.
+Kenshin Ushiroda I'm with you. There asn't much in this one :(
+9000Redline can't expect much from a ten minute video. Basically you don't want a lack of rigidity anywhere cause that affects your alignment when the car is being driven in the corner. The rubber bushings he talked about were the example of a less rigid car. It all comes down to no flex is best cause it keeps you from having to correct for, and deal with, alignment changes happening in the cornering process, which frees you up to drive the car through the corner instead of spending time correcting the changes that are happening to the alignment. The details are irrelevant. If it helps then, poof, there it is. Just like he said, you find the areas of the chassis that are spot welded and stitch or weld the seams where they meet. It's much easier for most people to brace certain areas than strip the car down to the bare chassis and start from there though.
All true. There's no question what the basic items are to do first. My question was mostly about the chassis welding though, stuff that I will never need for my own car I think :) Only pro drivers will be able to tell the difference on a seam welded chassis of a sports car, say a s2000 which is quite stiff to begin with, and a OEM spot welded one. I guess that's the question I had. How do you know how stiff a chassis is in general? Auto journos say they feel it, but they most likely feel a softer supension or bushings, cause they are much softer than spot welded steel components. So that's the interesting bit. I know that some local Honda club racers actually bought non-type R chassis because it was lighter, and they reckoned a full roll cage made it stiff enough, but lighter overall than a caged type-R. Hard to say if they were right, but those cars were fast. Basically the most basic civic, full cage, K20A engine -> rocket ship.
9000Redline
A good rule of thumb in a manufactured car is that if it has a soft top(convertable), then it is generally a lot stiffer chassis. The manufacturers make them that way cause they are missing the added strength of the hardtop connected at the A, B, and C pillars. So rigidity is built into the chassis and the plus is that the added strength is lower in the car than a hard top(lowering center of gravity).
I don't know about the difference between type-R's and non TR's but I doubt there is much as I'm sure they are identical in the chassis design(may be a brace or two added?), but there must be something that differs to make the non Type-R lighter and visa versa. That's what you need to research.
Can you make a chassis too rigid?
U WUT M8? I wouldn't think so, but I think weight becomes an issue.
Conceptually. no. The stiffer the chassis, the better the suspension does it's job, since only the suspension components are moving and that is generally easier to engineer and tune than the flex of the whole vehicle. However, given modern materials science, a chassis could be engineered to flex in just the right way to complement the suspension. An simplified example would modern composite bicycle frames with vertical compliance built-in while maintaining lateral rigidity.
I'm a simple man. I see a stabilizer bar/brace, I buy it.
whats the name of the song that starts at 3:15 ?
I feel like I've seen every second of this video before, except I know I have.
Songs used in this?
Question. doesn't full seam welding wreck the car ?
+Zac Youngson I'm not sure what you mean by wreck the car? From my experience with welding, stitch welding is actually stronger in some cases and would weigh less making it desirable
heard it has absolutely no give and puts too much stress on the panels causing cracks and tears
the panels would be the weak point so it's possible in areas like the shock towers. Some race cars are reinforced in those areas to prevent that, also weld-in roll cages come with plates to use as a base so the bars don't tear out of the floor during high impact. you might have already known some of that but I hope that helps
ffs.
alrighty then
What about the peugeot 208!
hahah the title
Anybody noticed there where 8 f***ing sharpies!!? EIGHT!!!!!!!!!!!
More more more ;D
7:08 shots fired at Audi
A Kindergarten Cop reference ..!
Dubya tee eff?
Hmm, here's a few mistakes that I found. 1) Polyurethane? It's never a better material to use in chassis engineering. 2) MK3 Golf, McPherson Strut Coilovers and lowered ride height leading to a better roll center and lower center of gravity. NOPE. Yes, the center of gravity is marginally lower, but the roll center height is less ideal, so much in fact, that your lower CG is a USELESS statistic.
+sakeido I do chassis engineering...
+sakeido There's no point in arguing. It's a modification because its cheap and easy to produce, which leads to great sales. Polyurethane goes in tight, and soon after the slightest usage becomes sloppy. It also doesn't add to spring rate of a suspension arm like a bonded rubber would (and any addition would be due to stiction and inconsistent). I'd suggest you Google "stiction" and maybe post a video of results of your so called "upgrade". A higher Durometer bonded rubber would be a MUCH better choice, otherwise heim, as BBI states. Heim is not for the street however...and will lead to decreased grip. Most of us drive on the street.
+sakeido You have a lot of subscribers for zero content. Weird. Well, I'm off to go post another drive video...then a feature-length rally video later this month.
+sakeido Idiot Mods, like polyurethane are 80% marketing and 20% product. It's not like any money was spent in redevelopment or advancing the overall design...it's just a mold. Check out companies like MetalCloak who actually redesigned a bushing for its given application. Slutty women are more available and more well known, but are you going after a slut or a refined Queen? Just different perspectives. Amateur RUclips is relative to Amateur design/product selection.
Simple video of NVH for a new condition rubber vs. hardened rubber vs. polyurethane at 0mi, 5000mi, and 100k mi. Pretty sure rubber would still be near silent and still be nice and tight.
MOAAAARRRRRRRR!!!!!!
It's not a toomah!
Fucking marvelous
