Could Saturn Astra get IRS?
Tuesday, September 12, 2006 12:04 PM
Beside the minor facelift & freshening... Look at what is underneith. Yay!! Is GM listening? Well, atleast they are testing it. So it is a start.
I always said they could retrofit the 4-link IRS from the Epsilon on the Deltas with 5-lug setup. Hell, it is in their parts bin.
Could this be it?
Either way, Astra is sound better and better.

That would great for GM if they put the IRS on the new saturn. We can only hope right? What would even be cooler is if that badge that's next to Astra on the back there made it to the states (Crosses fingers for 2.0 Turbo)

Crazy how from 1991-2002 GM had a perfectly viable small car platform with IRS, 4 wheel disk brakes, front and rear swaybars, a bulletproof selections of transmissions and tubular spaceframe construction....

....and they ditched it in favor of the POS Delta, which no matter how you package it ("global platform", etc) is nothing but a cosmetically upgraded J-Body with minor suspension upgrades.

Now anything going BACK TO WHAT THEY HAD FOR 11 YEARS is considered progress.

Typical.

For those wondering WTF... it was the Saturn S-Series, particularly the SC2 and SL2 models. Those cars had their weak points, to be sure...but everything GM learned from them was tossed out the door and it's been nothing but backwards steps and appearance mods ever since.

Good luck getting an improvement like that to the states. Not from GM. Not in this lifetime. As much as they want to play the part, GM *STILL* doesn't believe in the sport compact scene and what it represents. The Cobalt SS and ION Redline are quick "me-too" fixes to jump in, but they still refuse to make anything that is a serious contender in that market. I have doubts that they ever will. When even base model Civics have had unequal length A-arm independent suspension with front and rear sway bars since 1989, GM can't consider anything they've done short of the SC even a modest attempt to compete. But hey, the Delta is the "global platform of the future".

Fasten your seatbelts boys and girls! It's gonna be a long, slow ride!

Word. I predict the "Saturn Astra" to have IRS after the first re-fresh of the vehicle. About 5 years from now....

^It does kinda... But it looks like it is attached to the center of the body to the wheel, making it look like a IRS. And no not the gov't thing either.

But yep you are correct Jimmz in ALL accounts!
The S-Series was so ahead of its time. And it was the best effort from GM in attacking the compact car market in its time.
And if you ever went to the Spring hill, Tenn plant during the era of the S-series. I tell ya, it was a great setting there, as everything was made in-house too.
Sometimes I wished I would've bought the SC2 instead of the S/F in 2002.

i could almost follow except both rear pictures only have it on one side... and if you follow the angle it could realisticly be a panhard...

here maybe this will help explain what i'm trying to say

could just be added stability for the wagon body style?

i mean i could be wrong.. but knowing GM i wouldnt be surprised if i was right

The only thing odd about that is that for a pnhard rod to function properly it is supposed to be level, or nearly level, when the vehicle is at it's static ride height. That bar obviously isn't. As for "stability of the wagon model", a panhard bar at that angle would be extremely UNstable. Every time you hit a bump, it would push the rear suspension toward the driver's side.

did a quick google search on vauxhall astra rear suspention..

many of the road tests speak of a unsophistacated torsion bar suspention as apposed to a complex multi link layout?

and i pulled this off of test drive

"On the road the Astra is a competent all-rounder. It does without the independent rear suspension offered by rivals like the Ford Focus and VW Golf - although you'd be hard pressed to feel the loss from the driver's seat. Cornering grip levels are impressively high on all versions - although the steering feels slightly inert compared to the Ford Focus. Ride comfort is good and refinement at motorway speeds is excellent."

yes in most cases a panhard should be level as possible

but mounting point and length matters more dont forget


again not saying i'm right

just trying to figure out why its only on one side and a very thin rod..

Tell me about it. My wife got a '02 SL1 in May and I love the car except for the noise the plasitc makes on cold mornings that turn into warm days and the headlights that need readjusting because of the speedbumps in the parking lot. It handles like a slot car and I'm serioulsy considering donating the Cavy to Volunteers of America or some other charity and buying a Saturn coupe or Wagon instead of dumping $1,000+ into the Cavy.

Although that quote is an opinion, but you to put it like this, if you want the best possible handling/ride/control in a vehicle you will not be looking at a torsion bar.
And any reason it handles some what decent, it's because of the tuning, (i.e. shocks/springs/tires) which in this case, it is almost maxed out on this dated architecture. Not only that, but it has it's limitations aswell .
If you want the best possible ride handling/ride/control, all 4 wheels will have to work independently from one another.

I wasn't really refering to the quatlity part of that quote more so the style they were refering to for the rear suspention...

I'm really thinking them testing a panhard bar for lateral stability durring corners seems more like somehing gm would do. instead of just putting a dam irs in

Knowing GM, chances are you are right.
