It was an interesting car alright but that was before anybody knew anything
about road vehicle aerodynamics. Also it was years before the Germans figured
out the high roll center jacking effect. Porsche and BMW used it right up through
the 80's and into the early 90's as I recall. Late air cooled VW's still had it. The
Brits were 20 or 30 years ahead in suspension geometry. It must have been the metric system.
Newton was a Brit :) The Brits built better WW II fighter planes as well.

Hi Paul,
It was the swing axle that had the jacking effect;  the last Porsches
to have swing axle suspension were the 356 series in the early 60s; the
911, introduced in 62 and still in production, were the first
production cars with the full IRS.
Mercedes ran swing axles well into the 60s, but with the design having
only one swing joint on the whole axle, so half the camber change/ half
the jacking  effect.
VW changed to the 'Porsche type suspension' in 1967 IIRC. I cannot
speak for the Mexican made VWs, as they often ran outdated designs for
years after the German parent had moved on.
That swing axle suspension was the curse of the first Corvairs, Ralph
Nader's target . The later Corvairs after 66 I think, had Porsche type
suspension, but by then, "the dog had a bad name".  BMW had true IRS,
not swing axle, introduced in their 1602/ 2002 cars in the 60s. Datsun
all but copied it bit by bit in their 610 cars in 67 and did very well
in Rally competition due to it. It was known in Rally circles as the
Datsun 1600.
I agree with your remarks about the Brits; Jaguar had a true IFS/IRS
suspension in the MK10 sedan and the XKE in production in 1960; all the
work of Colin Chapman of Lotus fame.

Any trailing arm, unless it's real pivot axis is perpendicular to the longitudinal
axis of the car, will jack. It is the height of the roll center that
counts. This is why I get paid the big bucks :)

I totaled a BMW 700 at HockenHeim when the rear jacked. Of course
you could say I was going too fast :)
