Double Wishbone vs Macpherson - Pros and Cons of Each Suspension

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.

you're pronouncing mcpherson wrong

It’s text to speech

You're spelling Macpherson wrong. Just sayin'.

[@androo4519]

At least it's not being pronounced McPheeerson, like a lot of people do for no obvious reason.

MacPherson: muhk·fur·suhn

[@robi4387]

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

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

[@zahimiibrahim3602]

Not totally correct, most double wishbone systems are also designed to gain camber upon compression by using shorter upper wishbones and longer lower wishbones. Camber gain can be more precisely designed by varying suspension geometry compared to a simple strut system.

[@429thunderjet2]

No they, double a arms, technically don't gain positive camber like a McPherson strut does. Mcpherson struts tend to gain positive camber and roll over to the outside edge of the tire tread especially on the outside tire in a corner. That's something I liked about the 1990s Thunderbirds and even the front wheel drive Honda accords in similar years. They were four wheel independent suspension without those stupid McPherson struts. They kept the tires flat and planted to the road. Upper and lower A frames or wishbone types go more negative camber on the outside tire which is desirable to keep it flat and planted to the road.

[@429thunderjet2]

And upper & lower A frames tend to gain positive camber on the inside tire in a corner, which is also desirable. Where a McPherson again doesn't. They always react exactly opposite of what would be ideal. That's why I say they're cheaper and easier to build and work just good enough for Joe schmoe, that's all. Nothing to be seen here....😅

[@67daltonknox]

Macpherson is ubiquitous for one reason - cost.

[@zahimiibrahim3602]

Also space which is why they are used on all or almost all transversely mounted engine/gearbox FWD cars.
Longtitudinal mounted engine FWD cars usually have more room around the sides which allows double wishbones as the better option.

@@zahimiibrahim3602 Except for Honda. OK, back in the 90's. Transversely mounted engine/gearbox FWD cars such the Civic and Integra ran double wishbones. They dropped this setup in the early 00's. Cost and ease of maintenance.

[@429thunderjet2]

Exactly! the Accord as well. One thing I always liked about the Hondas.
