Active anti-roll Metro

Found this (warning: it’s a bit of a long read):

Now, who’s going to be the first to do this to their hydrolastic Mini?

Just realised the image link doesn’t show the full document.

The original 203 page document can be found here:

If you want to cut things short, buy a Citroën Xantia Activa - saves you hundreds of hours of reading the article and building that active roll control Metro.
Useful time saved to spend going round corners in your Activa at yet not experienced speeds and centrifugal forces. :lol: :lol:

>>Moose Test
The Citroën Xantia V6 Activa still holds the record speed (85 km/h (53 mph)) through the moose test maneuver, due to its active anti-roll bars.[2] This test is conducted by the magazine Teknikens Värld's, as a test of avoiding a moose in the road. The second place car, Porsche 997 GT3 RS was able to manage 82 km/h (51 mph)).[3] <<

Well, if you liked that you’ll love this:

It’s a later development of the low-roll Hydragas system. It’s a bit of a light read at only 14 pages or so.

IIRC that man Issigonis (and SU’s John Morris) patented a low roll torsion bar based system in the 1930s. Think it’s mentioned in the Jonathan Wood Issigonis biography (which I no longer have.)

Does make you wonder why we had to wait till the 90s for a low-roll production car. First the Xantia Activa and then the Discovery 2 with the ACE system. Is anyone building a low-roll car these days and if not why not? I can think of nothing but good coming from such a system.

Rover was in on the whole low-roll act in the late 60s:

I remember seeing a film at AP with the system fitted to an Ambulance.
That seemed to me to be the best application for it...
