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.

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.

@JTV84 7 күн бұрын

i wanted to see how camber changes during cornering or with changes to ride height. also he mentioned DWBs being more costly to maintain, failing to mention that maintenance is far less frequent than with McPs.

@walirifai Күн бұрын

Fun fact, the Porsche 911 GT cars have double wishbone suspension while the non-GT 911's use McPherson strut suspension. That's a unique scenario where the same model car has 2 different suspension configurations based on trim/designation

@blaizify 3 ай бұрын

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 3 ай бұрын

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 2 ай бұрын

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 2 ай бұрын

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....😅

@andrewwmacfadyen6958 10 күн бұрын

Camber gain can be designed in on both it is important countering the effect of body roll and tyre tuck when cornering. On strut suspension getting the roll centre , camber gain, roll steer where the designer wants is more challenging.

@429thunderjet2 9 күн бұрын

@@andrewwmacfadyen6958 not much gain on P strut, other than what its set at. if you mean positive camber, usually positive isn't desirable. Take a look at the amount of negative camber F1 cars run especially in the front. The only race cars that use (pogo stick) macpherson strut suspension is possibly world rally cars, but I'm not 100% sure on that and probably some SCCA stock class type stuff in this country. If it was so great why doesn't F1, Indy car, Nascar, IMSA, etc. use it. Even dirt track cars don't use it. It works good on front wheel drive street platforms because it doesn't take up much lateral room in the engine compartment. And its cheaper to build and works good enough for the average drivers.

@_entrxpy Күн бұрын

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

@grahamcrooks3581 3 күн бұрын

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.

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.

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?

@raulbustamante8337 Күн бұрын

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

@cpawp 3 күн бұрын

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

@juhakivekas2175 3 күн бұрын

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.

Personally, I'd rather have double wishbone or multilink, they tend to offer better handling and more comfort, but they're only found on more expensive models and while multilink have advantages over double wishbone, their setup/maintenance is more complex.

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.
