A Cadillac spokesman recently whispered into the ears of Automotive News that the first letter in each Cadillac vehicle is in ascending alphabetic order based on size. So by that logic, a vehicle placed above the XTS has only two letter options: Y and Z.
That is, if Cadillac continues its alphabet soup pattern its been carrying out since the introduction of the first generation CTS earlier last decade. The Wreath and Crest could, however, go with a more illustrative name for its flagship, like Ciel.
Or, it could be the recently trademarked “LTS“. Just some food for thought.
