The Ford Five Hundred is a full-size automobile that was manufactured and marketed by Ford from 2004 to 2007, and debuted as a 2005 model year vehicle. Deriving its nameplate from the ''500" suffix used by Ford on the Custom 500, Fairlane 500 and Galaxie 500 model ranges from the 1950s to 1970s, the Five Hundred was the larger of two model lines intended to replace the Ford Taurus (the Ford Fusion being the smaller vehicle).
