Moose test anyone
Discussion
I have to say, you lot are pretty funny!
I spent about 5 pages explaing why, using maths and physical facts, exactly what you have just said, but you all disagreed. So a thought i'd try a bit of reverse physcology, and guess what, by agreeing with you, you have now just said EXACTLY what i said about 300 posts ago...... hilarious!! ;-)

Yes, weight transfer is a function of the CoG height and track width, but there's absolutely no point in keeping the weight spread evenly across the tyres if the geometery + amount of roll means that the pressure gets put on the very edge of a contact patch because it's at 10 degrees to parallel with the road, then you've the same problem as the weight transfer - too much pressure on the portion of the tyre in contact with the road.
Which is what the Xantia suspension partially prevents, so ride height and narrow track or not, that helps generate a significant amount of grip despite the shortcomings. And just to add to that, the moose or 'elk' test relies a lot on transient dynamics, and the roll-limiting nature of the suspension ensures both that the response is fast and the unsprung mass settles rapidly.
Magic eh? And it did it without breaking the laws of physics too, who woulda thought?

I think this argument has got away from the point of the Activa's suspension. It was never designed for ultimate cornering performance, it was just to make a car with a very comfortable ride that would also go around corners without falling over.
That video with the Xantia sliding around a corner may have had a little to do with the driver's skill/insanity.

I never understood why all these yellow Xantias falling over

Reminds me of the one about pushing Almeras over a cliff

Imagine how good a supercar would be with active suspension. Has anyone made such a thing?...

You've never driven a car with active suspension before have you.
Why are they so rare then?http://www.lotusespritworld.com/EOtherstuff/sid.ht...
Found this is on the Activa from Practical Performance Car on a fiat forum post
The Citreon Zantia Activa will pull slightly more G force in a corner than a Honda NSX or a Ferrari 512BB
& not sure if this has been posted already (sorry if it has) but looks good
