There already exists an SAE class on CTAN contributed by Axel Franke, which although it is 15 years old (last update 2000-11-14) is still workable with a few tweaks, I think. The problem I am facing is that there is no SAE bibliography style file that exists as far as I know (I was looking for an SAE.bst for traditional bibtex). I started down the road of creating a new bst file based on the ieeetr style (which itself is based on the plain style), but I found this was cumbersome and still difficult to get exactly what I needed to satisfy specific SAE publication requirements. I would like to modify the SAE class to bring it up to date, and provide a biblatex solution (similar to the package biblatex-phys).
SAE is unfortunately very MSWord-centric, and they only have template files in MSWord. Citations are currently handled by most people I know using Endnote/Word with a custom Endnote output style and reference type for SAE papers (mainly to include the text "SAE Technical Paper YYYY-01-NNNN" for the paper number as part of the citation).
I'm not sure that the biblatex-phys package would be the best place to start for this, or if anybody has done something similar for SAE papers in the past?
