The Dodge Diplomat is an American mid-size car that was produced by Dodge from 1977 to 1989. At launch, it shared a common design with the Chrysler LeBaron and for much of its later production run was the counterpart of the more upscale Chrysler Fifth Avenue and lower priced Plymouth Gran Fury. 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 a sedan; in 1978, station wagons were added as replacements for the discontinued full-sized C-body wagons.
The Diplomat was offered with a 225 cu in (3.7 L) straight-6 engine a well as optional 318 cu in (5.2 L) and 360 cu in (5.9 L) V8s. The Diplomat, along with its Plymouth Gran Fury/Caravelle twin, were popular police cars both in North America. The three-speed Torqueflite automatic transmission was most popular, but a manual transmission was available until 1981 only on six cylinder and 318 V8 models.
