Just read that the new WRX will have a double wishbone setup, which I believe is different that previous years which I think were multilink. I watched this to get a better understanding.

 

The current generation has wishbones...

Pretty much all of the current Subarus have the same wishbone rear suspension. Kinda crazy.

 

if you are referring to pre-2008 impreza's, they are regular McPherson strut suspensions in the rear, even though they have "lateral links" but these are basically just the lower control arms. Heres what an actual multi-link is

Ah okay sorry for my ignorance.

 

 

win.

 

Leeloo Makes my wishbone double!

 

Ah Milla Jovovich, before you wasted your career making the same ****ty resident evil movies over and over again.

 

I would take a Multipass at the *** of Leeloo Dallas.

 

THIS is a double wishbone suspension configuration:


THIS is what the "outgoing WRX" has in the rear:



So it is almost a dual wishbone suspension, but it doesn't actually have 2 wishbones. It is an upper single wishbone and the lower is a trailing arm/lower control arm (which is not a wishbone), though it might operate similarly given the mounting points of those arms. I'm not sure if there is any good reason to use one over the other, though I guess having a separate trailing link allows you more independent adjustability.

The benefit of a dual wishbone type suspension is basically that it allows for more precise control of the wheel position and camber/toe/caster angles throughout the range of the suspension travel. It's pretty cool to have that on the rear axle, but it's twice as cool to have it on the front axle because it will actually allow you to steer the car better and have more traction on the front axle (where subarus traditionally need more traction under extreme conditions - to combat understeer).


This is a Honda Legend (or Acura RL in USDM) dual wishbone front suspension.


With this configuration, you will also feel much less impact force from the tires through the steering wheel. This allows you to maintain your steering angle more consistently and with less effort.

 

sooo...I was right?

 

hmm, you are a bit off on some of your points there.

First off, "dual-wishbone" is more or less just a marketing term thats been around for 60+ years to describe an un-equal length control arm suspension, where the upper arm is shorter than the lower arm, and in practice all unequal length control arm suspensions work in the same way, they create negative camber gain when compressed. There is no specific advantage of having an unequal length control arm layout in a upper/lower "wishbone" configuration vs upper/lower control arm + trailing arm as in the rear of the WRX. It usually just comes down to packaging.

Also, a dual wishbone layout has absolutely NO advantages for better toe/caster control vs. any other unequal length control arm layout, or even a macpherson strut suspension for that matter. The entire point of the unequal length arms is for camber gain, thats all.

 

Right? Someone said you were wrong?

The '15 has wishbones... But the wishbones aren't new. They've been around since '08.

 

Right as in double wishbones are new to the scene.
