text: 1977 The 1977 model year brought changes to the Dodge Monaco lineup as a lingering result of the 1973–1974 energy crisis, especially as Chrysler decided to move the Dodge Monaco, in name form only, from the full-size C platform-body to the mid-size B platform-body line up for the 1977 model year. The entire 1977 Dodge Monaco lineup received a make-over. The previous model year's full-size C-body Dodge Monaco (from 1976) became, just for one year only, the full-size C-body 1977 Dodge Royal Monaco until its discontinuation from all production at the end of the 1977 model year. The mid-size B-body 1977 Dodge Monaco two-door coupe, four-door wagon, and four-door sedan replaced the previous model year's Coronet hardtop coupe, four-door wagon, and four-door sedan. These cars were "corporate twins" to the new-for-1975 "downsized" Plymouth Fury. The 1977 Dodge Monaco Brougham four-door sedan replaced the previous year's Coronet Brougham four-door sedan. The 1977 Dodge Monaco Crestwood four-door wagon replaced the last year's Coronet Crestwood four-door wagon. However, the 1977 Dodge Monacos differed only slightly from the 1976 Coronet versions. The 1977 models received a revised front-end design with stacked rectangular headlamps.
  1978
  For the 1978 model year, the mid-size B-body 1978 Dodge Monaco was unchanged from the previous model year. It became Dodge's largest car during the 1978 model year. The Dodge Monaco was discontinued at the end of the 1978 model year. The B-body cars continued in the form of the Dodge Magnum until 1979.
