The 1973 oil crisis caused significant changes at Dodge, as well as Chrysler as a whole. Except for the Colt and Slant Six models of the Dart, Dodge's lineup was quickly seen as extremely inefficient. In fairness, this was true of most American automakers at the time, but Chrysler was also not in the best financial shape to do anything about it. Consequently, while General Motors and Ford were quick to begin downsizing their largest cars, Chrysler (and Dodge) moved more slowly out of necessity.
