So we still don't know how it stacks up to the current double wishbone system. Let's weigh up what we know so far ...
On the positive side :
* Lighter
* Fits in wagon (not applicable as a positive for myself, but it will be for others)
* Improved ride quality and NVH
On the downside :
* Cheaper - possibly meaning inferior quality materials?
Unknown:
* Performance - there has been NOTHING said about this new system in comparison to the existing one in terms of outright handling competency. Are we to presume that this factor is being avoided deliberately? ie. the existing double wishbone setup is preferable for this aspect?
Until there is evidence that this new system can match or better the existing one in terms of outright handling competency, I am yet to be convinced.

I would assume it's cheaper due to Dana Corp. doing the whole thing, rather than 40+various suppliers who all need to make a little profit from each component. Having it built in a nearby factory also means the transportation costs are far less.

Oh he of little faith.
Do you honestly think Ford would put in a new IRS that is Worse than the current one?
Never.
Holdens one will now look so out of date, it is not funny. (nothing new here)

That is exactly what I am trying to determine! I would hope that things would step forward, or at the least, sideways... but WE STILL DON'T KNOW!!

Just because the Holden IRS is old and simple and based on the Datsun 120Y doesnt mean that is isnt effective. I for one think its a far better system that the live rear end in the Falcon when taking high speed corners with bumps. As for being out of date, Pursuit ute with horse and kart leaf suspension isnt exactly cutting edge either, but I gather it's very effective also.
Looking at the pic RPO83 posted in the other thread, it seems it's still connected at the top of the spindle with a rod (one connection at wheel, one connection at chassis), although not like a triangle (one connection at wheel, two connections at chassis) as a wishbone would be. There still seems to be a lower wishbone. If there wasn't any "control Blade", (which I am assumong is the red thing pointing out the front) then there would be lots of unrestrained transverse loading, but the 'blade' should alleviate most of that. I'd say that it's as strong as (or stronger than) the double wishbone setup.
After the whole Mr Informer thing, I don't want to assume that everything on these forums is accurate, but RPO83 did quote,
"Handling has always been a hallmark of Falcon, but the new Control Blade IRS raises the bar to new heights."
Although I know RPO83 has been accurate on many things.
