Many of the items on this list are not "official," meaning certain acronyms regarding specific products may have been created by the automotive public and are not the official designation of the manufacturer. As such, this isn't intended to be the final authority on the acronyms of the automotive world, this is intended merely as a guide for readers to understand an unknown acronym they may come across.
