What were all the platform designations?

[00Silverado4x4]

I know that the 88-99 era was GMT400, 99-07 was GMT 800, 07-13 are the GMT 900, but what before all those? Have they always have a platform designation for all the different versions of our favorite GM vehicles? Curious minds want to know, well at least mine does...lol

not sure about the rest of the trucks, but firebirds and Camaros were f-body's, impala and grand prix were the w-body, the traverse, enclave, and acadia are all on the llambda platform, the cruze and therefor enquinox and terrain are delta platform I believe, lacrosse, the new impala, Lucerne, and caddy xts are the epsilon II platform, ats and next gen Camaro are alpha platform, current Camaro, cts and chevy ss are on the zeta platform.

Well I think it was K series before the GMT 400's, I guess they just went by year.

Yup K series was the 4x4 platform and C series was the 4x2 platform.

Yup K series was the 4x4 platform and C series was the 4x2 platform.

I knew about the K or C, I just didn't know if that was a platform designation or just the option code or 2 or 4 wheel drive. After all they still use the C and K on these trucks, well at least as of my model year anyway.

The terminology that drives me nuts is the NBS, NNBS, OBS, OOBS, etc, etc. Those are the ones that are really misleading to me.

 

So what's a 700 anyway? J/K Rob, friendly ribbing intended.

I've never heard of a 700-series either.

 

Good article on GMT-series vehicles:

 

http://en.wikipedia.org/wiki/GM_GMT_platform

 

And the real benefit to using these numbers is only for dual model years like 1999 or 2007 when you could buy either one. The OBS/NBS is too hard to use now because some people call the current 900-series trucks NBS and some NNBS or other silly stuff. Just makes no sense when it can be up to interpretation.
