The Dodge Diplomat is an American mid-size car made from 1977 to 1989. It is essentially identical to the Plymouth Gran Fury in the U.S. market and the Plymouth Caravelle in Canada. It was also sold in Mexico between 1981 and 1982 as the Dodge Dart, and in Colombia as the Dodge Coronet. The Diplomat was initially offered in a coupe and sedan. In 1978, station wagons were added as replacements for the departed full-size C-body Wagons.
The Diplomat was offered with a base 225 cu in (3.7 L) straight-six-cylinder engine, in 318 cu in (5.2 L) V8form, and an optional 360 cu in (5.9 L)) Diplomat, along with its Plymouth Gran Fury/Caravelle twin, were widely favored as a police car both in the US and Canada. Aside from the 3-speed Torqueflite automatic transmission, a manual transmission was available in some years and markets on six-cylinder and 318 engines; the 360s were automatics only.
