What I find fascinating and possibly someone can elaborate on this, is the fact that the GM central tunnel X frame introduced on the 1957 Cadillac, was both controversial and dangerous with at least a couple lawsuits filed (all GM won which is another story in itself).

But when GM decided to start ditching this design for a more conventional perimeter box frame in 1961 starting with Oldsmobile and Pontiac, there was little fanfare or even advertising within ads or brochures about this new frame. In fact, I only saw a 1/8 page size section in the 1961 Oldsmobile brochure and that is about it.

If this new “Box Strength Guard-Beam Frame” was so revolutionary and superior to the X style, why wasn’t it advertised more? Brochures had a habit of showing frames regularly up to this point and even beyond like when Cadillac itself dropped it in 1965. But when first introduced it was a different story apparently?

Ideas? Comments? Suggestions?

Thanks!
