[Kal-El]

The sedan and liftback were combined in N. America mainly for marketing reasons. It saves a lot of money to consolidate marketing/advertising particularly with the small car segment where automakers make very little margin in America.

Also, most small car nameplates have traditionally been offered in sedan and hatch versions in America. I can't recall a company that has used two nameplates for a related sedan and hatch, although I'm sure there's an example somewhere in history.
