That's not a car - it's a full-size clay model, built up on a studio armature, shot on the enclosed Patio adjacent to GM Styling.

It was also done in late 1962 as a possible face lift to the '64. Remember, body styles didn't stay for more than a couple of model years on cars back then. Corvette 1953-55, '56-'57, '58- '60, '61-'62. Full size '55- '56 9'57 ?), '59-'60, '61-'62, '63-'64, '65-'66, '67-'68, '69-'72, etc. The idea of 5 years with the same basic body and minor cleanup would have had many talking and the idea of a 15 year run on the '68 model would have horrified them.

Yet today, the C5 stayed essentially the same with no visible changes from 1997 to 2004 (8 years) and the C6 from 2005 to present (8 years). I know it is more economical, but I miss having some changes.

I understand that it was a clay model but look at the right side taillights, they must have had 2 ideas they wanted to show.

It's so cool to see the "process" as it existed back pre-CAD/CAE and computer modeling.

John - surely those clay models were on bucks, right? I wonder how heavy and how maleable the final product was.

I also wonder to what extent style has been affected by the tools designers use ..if stylists of today have been freed to try/see see/try ... and how much the loss of the tangible, tactile full scale model in clay has affected designs (assuming they don't use full scale clay models today.)

Believe it or not design departments still uses clay models for some things.

While talking with a GM design employee at Detroit Autorama about my car, subject came up when we were talking about side vent on car as it's base designed was done in clay. I was shocked when he told me they still used clay, I thought they had gotten away from it.

We called those models "clown cars" back in the day - each side was different to some degree, to explore alternative themes on the same basic shape.

The clay models were built up on steel armatures made from square tubing, with adjustable wheelbase and track, with plywood formers cut to rough profile every ten inches, and clay on top of that. A full-size clay model weighed about the same as a real car, and took a LONG time to develop.

Full-size clay models are still used today, but only as the final step in the process; 95% of the surface development is done on the tube, and that math data is used to mill the clay model. Frequently a splash is taken off the approved clay and used as a mold for a fiberglass model, which can be painted (or shown as a "concept").
