Are you assuming its a straight bar and not rose-jointed to the underside of the diff?

Ah, I see, have just looked at the earlier pics and can now visualise how it works. I am hoping to visit factory next Friday

Quite a while ago I advised Morgan directors in a technical report on Morgan suspensions that their Watt's linkage had the links at the wrong angle, they must be horizontal not as in the CAD image. I guess they would already have had their doubts as soon as they bounced the car though. I was then told that there was no room left for a Panhard underneath across the chassis to replace the Watt's where it should be, so they had to put it high up and diagonal as on the AR6 - seen that beast twitch (yaw?) on full power changes then on the track, wonder why that is then?
I would not put a Panhard rod at anything other than straight across the chassis, as besides other effects, lateral loads on the axle (cornering) will put fore/aft loads into the axle too. Also consider single wheel inputs - left wheel will follow a path that is in pretty well a vertical plane, the right wheel will not, it will arc about the left wheel. OK may be trivial and may not affect things in practice, but the Panhard rod should be where a Panhard rod should be to give the right restraint. The packaging is tight, we know, but it is possible.
I leave it to you to guess where the Panhard is on the 5L.
Suspension design is forever a matter of compromises (as is life they say?) each to their own, some things that should not work do quite well, look at the ridiculously high roll centre on F1 cars. We have ours below ground level and goes even lower as people modify to get negative camber etc etc. What is ideal? That's all - late now - Peter.

The opportunity to redesign are few and far between. I’m sure it could have been squeezed in with some re-profiling of the rear links (IMHO).

Visited factory today for the first time and thoroughly enjoyed it. Saw a number of ARP4's in various states of build from initial engine install in chassis to near complete. The engine installation looks very neat. I did take some pics but quality is poor from my 'phone.
I think the car looks fabulous and exceeded my expectations. The launch car is now on the road with final adjustments being made - exhaust sounded great!
