Re: How does torsion-level keep the car level on braking and acceleration?

The SAE publication covers a bit of the theory behind those questions. In actual practice I cannot see as much dive or squat reduction as they claim but maybe some is there. The article is on site if you have not had a chance to read it.https://packardinfo.com/xoops/html/downloads/SAE_Torsion.pdf

You might also search youtube for some videos on TL tests. There are a couple of videos where the effect is seen and a halfway funny one where they did a test with a Cadillac, another hi end car maybe Lincoln and the Packard over a notoriously rough Detroit RR crossing. The Packard saided thru while the other two had interesting experiences.

The comparison demo is also In the Allison DVD sold by Motor City Packards as well as a video of a 54 Packard going over the same tracks. IIRC the DVD said the 54 was owned by one of the engineers doing th demo so it was not driven anywhere near the same speed as the cars in the demo. That is probably a good decision because by the looks of things at a slow speed, the Packard would not have fared well either if it went much faster.
