Double Wishbone vs Macpherson - Pros and Cons of Each Suspension 

McPherson for manufacturer and double wishbone for customer.

I’d go double wishbone suspension over McPherson any day.

Maybe talk a little more about the more technical aspects of each. For instance, roll centers, instant centers, camber gain...that sort of thing. It would also be interesting to compare something like a modern Porsche 911 front suspension (last I remember they used struts) and an economy car...maybe like a Corolla, just to see how much and where they differ and if a Porsche really has that much difference in that type of design over a "lesser" vehicle.

Sorry but this info is blatantly wrong. Double wishbone does not have "dynamic camber changes mid corner", that's camber gain, and that's literally what macpherson struts do and double wishbone was designed not to do. 0/10 effort

you're pronouncing mcpherson wrong

it is incorrect to say that mcpherson produces more body roll since the wheels are interconnected. McPherson is a completely independent design. What really happens is that it has an arc shaped travel, changing camber depending on its position, but that only affects the contact patch and the wheel incidence on the ground, not the roll of the vehicle

2:20 picture is double wishbone while you are talking about McPherson suspension

My Alfa 156 has double wishbone and she handles great, one big advantage of double wishbone is that the wheel is always perpendicular to the road surface, thus maximising the contact patch, whereas the McPherson moves in an arc, the inside wheel in a curve has minimum contact.

Macpherson is ubiquitous for one reason - cost.

The weight isn’t really true. McPherson systems are inferior because the forces aren’t all aligned with the arms, so they introduce bending moments in the system. That requires having beefier parts in order to achieve the same rigidity as a double wishbone, so that means more mass. So this pretty much equals the extra components in the DW system

my car has the double wishbone, and it's exactly what you said this is pretty stable especialy in corners

Porsche has been sticking to multiple link McPherson on the front for decades as well as bmw and mercedes, for a good reason. The standard McPherson is what you said but the ML version of it is the way to go. Body roll can be fixed by well engineered sway bars. Have you tried the E60 with the hydraulic sway bar?

MacPherson: muhk·fur·suhn

One other thing that is not discussed is the need to reduce the scrub radius for Front Wheel Drive use. This is more easily achieved if the upper wishbone outer ball joint is located above the wheel. Cannot do that with Macpherson.

I had a car with McPherson struts, and I thought they were just cheaping out...tying into the shock like that!

Some of his strut pics are actually pics of double wishbone suspensions, just with a strut like shock spring tower

terima kasih pencerahannya...menambah wawasan dan pengetahuan saya..👍🙏

The addition of additional components

Upper and lower control arms suspension. It's been tried and true time tested over decades. Also used with torsion bar as well as coil springs. I also prefer rear wheel drive. McPherson Struts enabled transverse engine front wheel drive in cars, for space. Not a fan of all that. I have no choices either selecting a sedan this day and time.

Informative. Thanks. ❤

Error: at 2:40 You show a double wishbone suspension which happens to use a Macpherson strut for the spring element, a blend of the two systems. But you call it a Macpherson.

😊🙏 Always wanted to know this ... Thank You So Much OBD Insight for this well presented tutorial on the difference , con & pro of Double-Wishbone or Macpherson Suspensions ... 🙏🌷🌿🌏✌💜🕊

Thanks I was always curious what the different suspension set ups were

I would claim that 4 times out of 5 MacPherson is heavier than a proper dwb - or even 9/10. One of the worst features of MacPherson is that when lowering a car the roll centers fall 2.5 to 3 times as much as the lowering of the car and then you need a stiffer AR-bar which is ok for a track car but road tuned cars do not like excessive warp-stiffness. Also MacPherson tends to loose camber gain quickly when dropped. Further more MacPherson has a lot more friction as the dbw. And yet, most cars with MacPherson handle still well. Also I think the big noise about Porsche GT3 having a dbw and being like "night and day" compared to the older MacP is pure marketing bs. When something is so good to begin with there is no way to make it "night and day" better. It certainly is a little bit better.

Why do the old 911s have MacPherson suspension? Or is it not exactly the same because it is torsion?

Strut design requires heavier metals on struts to hold the weight of the car. Steel and cast iron parts are used for them, adding weight. Double wishbone allows upper and lower arms to share weight, with suspension dampers handling only dynamic load. Each of the three can be made in lighter aluminum, reducing overall weight for practical applications

How about leaf springs? Can you explain on video, pros and cons

The Toyota Camry and Avalon used the best of both worlds in their double-wishbone MacPherson strut front ends.In late 1984 (2nd year of the Camry) one of the line workers was doodling on a paper towel at the dinner table, and figured he could eliminate about 50 parts and 60-70 pounds from the Camry's front end and make it BETTER. They STOPPED THE LINE and re-tooled the worker's design and he got $400,000 for the improvement. In 1985, the Camry got a 2.5L 163 HP V-6, which the original front end could have never handled. I owned the original 1983 1/2 FIRST production Camry LE. Then I drove the V-6. Night and day difference in ride and HANDLING. I ended up buying a gall-bladder surgery instead of a new car. I drove the '83 1/2 Camry 14 years and 330,000 miles, and sold it to a co-worker (at the time) and she's STILL driving it with 2.2 MILLION miles on it-engine and transaxle haven't been touched. BTW, an '88 3L V-6 Camry has the mileage record. 6.3 MILLION miles. BP gives him Castrol Syntec and maybe free BP fuel. I've seen the BP commercial with the car in it.

I prefer double wishbone in all kind of cars the problem is only that most of my cars does have McPherson and are difficult to rebuild.

Thanks...👍

Nice

My MR2 has McPherson suspension. Usually ok, but many vehicles were lost by snap oversteer, when the contact to the road suddenly gets lost.

How tf are the wheels of an axle with mcpherson suspension interconnected?

Double is my best.

I have solid axles in my jeep jk and no steering or racing :)

Twice gave picture of double wishbone suspension when talking about Macpherson

Double wishbones are costly for the consumer too. They need replacement every 4-5 years

@3:58 he speaks about MacPherson but shows q Double WishBones front suspension architecture.

At least 2 of the systems pictured are hybrid between Double wishbone and Mcpherson strut.

What is a Macrson strut suspension?

My ALFA 156 has DW - suspension on it and it lets you everything you want on the road.

Interestingly, the Boxster has macpherson struts front and back.

I have learnt a new word today.

Some company tried to sue GM for using McPherson strut.GM.said you mean one named after GM engineer McPherson.

Rear suspension at 2:24 has double wishbone.?

Double Wishbone Handles Way Better than Macpherson struts My choice is Double Wishbone

You didn't mention braking! This is where Macpherson struts fall over, forming the top suspension link they can have stiction introduced under heavy braking, affecting operation and movement. Double wishbone completely eliminates this.

mackfersun? Do you mean MacPherson? The name comes from American automotive engineer Earle S. MacPherson, who invented and developed the design. Wikipedia

Jesus christ so many English teachers around

McPherson for me all day, because of my country's bad roads. Double wishbone maintenance costs just aren't worth the advantages.

At 0:53 he says " double wishbone suspensions allow the rear to toe in". Unless you have four-wheel steering, I don't you think you have a steering knuckle on your rear tires. Is this computer generated text and voice?

In late eighties, announcing 1987 lebarons, here called phantoms, they mentioned McPherson front suspension as somewhat "high tech"

Double wishbone keeps tyre more perpendicular to the road - so better...

Lot of people complaining about the AI content of this video. That's not allowed as AI is infallible.

I could have stopped when I heard Mak Fur sons. Nice drawings though.

Honda’s double wishbone

😂 i can name one best handling sportscar out right now is on MacPherson.

I don't care how good the video is, if it's any kind of AI speech, I'm gone.

Scooby. I see now.

This ai generated bullshit is ridiculous...🤦

Narration not matching illustration and wrong pronunciations - rest of the video probably shit too. Why do it if not done right?

Honda, bring back the bones.

Jag XE has front double wishbone Porsche doesn’t😂

the wheels are not interconnected with Macpherson, they are independant!

I dumped a Toyota Tacoma because snow chains won’t fit on the front wheels. The Tacoma uses McPherson struts which have no business on trucks.

Wishbone suspension is stronger. Macpherson restrict the tyre size that can be fitted.

There are virtually no cons of double wishbone for the user. Weight, "repair difficulty" and expense is essentially not even worth mentioning. MacPherson benefits the manufacturer only, for the most part.

These will be the good old days back when computers couldn’t pronounce some words . Let me get a little 🖕in while I can to the future ai leeder of our world 😊

This video is pretty much incorrect.. struts take up more space and higher up in the engine compartment. also, the amount of material needed to hold the strut secure adds weight, and takes space. struts make for heavy large 1 peice body (unibody) designs, where a arms use a (frame) where body panels are replaceable, and not part of the structure.

The McPherson suspension is pure genius for its low cost to car manufacturers, who are all in for greater profits, but it is a cheap and fragile set up, not suitable for most real road conditions.

mac-FEAR-son strut

There is no sports and powerful car with McPherson. Draw your own conclusions!

Advantage of McPherson strut - cheap. Advantage of double wishbone - everything else.

McPherson is the cheapest independent suspension system - that why it's used almost everywhere. 😅😅😅

AI generated video

Horrible AI narration. Turned it off after 7 seconds.

It's pronounced Mac Phearson. NOT macferson

no thanks, i'll stick with torsion bars instead

Double wishbone .

Multi-link is better than all for street use. Double wishbone for racing

mac pherson, said mac fer son! same as Philippine...

Double wishbone for me but not my wallet sigh

Certainly Doublewishbone'd Car from China. 😅

It’s pronounced Mac-fear-sun, not Macfur-sun.

see you later. aligators

Struts suck. No matter how you tune them, by nature they give you bump steer

One would assume that you would try to get the pronounced ration right of McPherson before putting it on RU-vid can we take anything seriously when you can’t even pronounce things right?

The only advantage of mcpherson is lower costs for car makers, it has ZERO advantage for consumers.

Junk AI video with generic and often false info

When Macpherson presented his new and cheap, to produce "suspension to GM executives. They found it Too Cheap and Too poor to fit to their cars and Refused it outright. Clearly Cheaper attitudes took over, decades later. Mac Pherson suspension is and always has been substandard . ONLY serious workaround 'fixes' has improved it.. Some. Which is simply stupid as the fixes cost more than Not using it in the first place. Porsche is a clear example of dogmatic German stubborness, they even hang their power trains out behind the rear axle Audi similarly stuffs their entire drivetrain out ahead of the front axle. Reality of 'German engineering' ended with the Launch of the last V2 rocket.

"Mackferson" 🙄

20% factual BS and 100% annoying text-to-voice bot

mackfersen SKOL !

AI generated speaker.

4:10 no need to shout mate lol

It's pronounced "Mc-FEER-son." AI needs more work.

AI generated video it’s pure crap riddled with false claims and descriptions

AI speech is so annoying

Don't know how much longer I can take the stupid AI voice butcher the word "McPherson".....

The McPherson suspension is horrible,its worse in cars that have the setup on all the four wheels,this because it makes me carsick
