I would have never known that, and I'm sure most people looking at that photo wouldn't either! That is a cool detail, thanks for pointing it out.

Here's an example of one. As you can see, details/changes are often modelled manually. To reduce cost, one option is to use the frame of an existing vehicle, on which sort of "clay sheets" or thin "blocks" are mounted and then modelled either by machine or hand, depending on availability of 3D-data. Another option is to make a completely new frame for the clay model, made of whatever material is reasonable. It could theoretically be made of wood, polymer, metal or whatever, depending on the purpose of the full-size model (exterior only, interior, engine bay etc.). Sometimes the models have to be driveable. Quote:
Either way, it was and still is true craftmanship. And art. Funny to see that the challenges at the time (regarding cost, industrialization, marketing etc.) were pretty much the same as nowadays. Speaking of challenges, it'd be really interesting to get some in-depth info about GM's product development / industrialization process back then. |

Re: 67-72 Development/Concept Photos Galore!
Yes, thanks for bringing this back to the top. Simply fantastic thread. It would be fun to have one of those clay models made in 1963 or 1964 for display in my yard. I wonder if they were all disposed of.

The data can then be transferred to the clay modelers and the surface created in clay for review. This can be full size, half scale, quarter scale, as desired. You are also correct that it is not a "giant block of clay", but a layer of clay added over an "armature", that is, a structure of metal, wood and/or Styrofoam. After there is agreement that the surface meets Studio expectations then it is sent over to engineering for evaluation, to make sure the panels can be formed and establish details like door cut lines, "B" surface details like what you see when you open the doors and such, material thickness and component packaging. Once that's done then the engineering team can start designing up the individual parts and details in earnest, in a different software that is more conducive to part detail and manufacturability. It would be easy (...easier...) if this was just a straight flow through process but naturally it is an iterative process, as engineering learns that certain items won't work or can't be made. The Studio is also characterized by changing their mind or wanting to add content late in the game because they just saw the latest whiz bang thing or because they want to introduce the latest styling theme on the product just before it launches. It is a constant game of give-and-take as a result of the creative tension between the two groups and their requisite personalities. K

![]() I guess this depends on the financial situation, development/design stage and philosophy of the OEM. I know at least one European OEM, which store some of the final full-size clays somewhere in a (or several) warehouse(s). |

More permanent properties, like fiberglass bucks/mockups and actual show car properties are kept. Clay models are photographed in great detail and the photos cataloged and stored in the basement of the Studio. Unfortunately we had some flooding in Southeast Michigan a few years ago and many items were lost or damaged. K

Very cool thread to go thru, but am glad they turned out as they did cause some of those proto types are ugly.

Re: 67-72 Development/Concept Photos Galore!
I am currently working on an update for the 73-87 development photos, and within my latest photo set for that, I also found the photos below and thought they would best be placed here given their dates.
Aside 4, Chevrolet Tempo Before seeing the photos below, I had never heard of the Chevrolet Tempo concept. Even after seeing that it existed, I could not find any information on it to support these photos. With that said, the only information I have on this concept is what I've gathered from the photos themselves. It appears that after the shelved Blazer concept that GM was working on in '65, they moved on to a similarly sized light utility truck called the Tempo in '67. Although the Tempo was similar in size to the original Blazer concept, you can see that it was a completely unique design, sharing almost nothing with the original Blazer. By '70, GM was clearly as far along with the Tempo concept as they were the original Blazer before it too was shelved. We know now that Chevrolet would instead import the Isuzu Faster and rebrand it as the Chevrolet Luv starting in '72, effectively killing the independently designed Tempo. I have no relevant knowledge on the Luv, so I'm not sure why GM chose to use the Luv over the Tempo, but my only guess is it was related to cost. With that introduction, I'll get to the photos! -July '67 During this time, GM started laying out potential profiles for what would become the Tempo concept. These early profiles depict it with more of a cab over design. ![]() ![]() -July '70 Fast forward to 1970 and GM has finalized the design of the Tempo and has built several prototypes. The first prototype is the clay model, and the second white Tempo appears to be a preproduction ready fully functional truck. ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() That's all the information I have on the Chevrolet Tempo. If any of you could provide further insight that would be much appreciated!

Re: 67-72 Development/Concept Photos Galore!
Extra Photos, GMC
-March 1970 Along with the Chevrolety Tempo photos, I found a few extra development photos of the C10 to fill in some gaps from the main photo sets. The first few photos pick up after the last photo for the development of the GMC. At the time I wrote that post, I did not have these photos and assumed GM did not propose any significant updates to the GMC for '71/'72. As it turns out, they did in fact prototype several grill updates for '71/'72, including one single headlight design like the Chevrolet. ![]() ![]() ![]()
