In 1982, Plymouth downsized the Gran Fury again, this time sharing the mid-size
M platform with the
Chrysler Fifth Avenue (called
Chrysler New Yorker/
New Yorker Fifth Avenue for 1982 and 1983) and the
Dodge Diplomat. In addition to the R-body Gran Fury, the M-body Gran Fury replaced the M-body
Chrysler LeBaron, which had moved to the
compact K platform that year. Now considered a mid-sized car, this generation Gran Fury was close to the exterior size of what was once the compact
Valiant and
Volaré but offered more interior room. The M-body was in fact heavily based on the Volaré's
F platform. Like its predecessor, the 1982 Gran Fury was introduced later than its Chrysler and Dodge siblings; the
Chrysler LeBaron and
Dodge Diplomat had used the M-body since 1977. For 1979, all M-body coupes were offered with 2 different roof treatments. The Chrysler LeBaron, Dodge Diplomat, Plymouth Gran Fury (in the U.S.) and Caravelle Salon (in Canada), had a more formal rear side window treatment with a tall, narrow rectangular shape, rather than the “triangle” shape of the standard trim model. This more formal coupe was only sold for one year. 1982-1989 Plymouth Gran Fury shared the Dodge Diplomat's front and rear fascias. They were virtually identical with the exception of badging. Once again, the third generation Gran Fury was available in base and higher-end "Salon" trim. As in previous years, the higher-volume Gran Fury base model catered more towards fleet customers while Gran Fury Salons were geared more towards private customers and offered options such as full vinyl roofs, velour upholstery, turbine-spoke wheels, power windows, and power locks. Although available to retail buyers, Gran Fury was far more popular with police departments and other fleet buyers, primarily since the car was reasonably priced and had a conventional drivetrain with proven components that could withstand a good deal of abuse. The Gran Fury, however, was much less powerful than both its Big Three competitors as well as the Chrysler Corporation's earlier police offerings. The most powerful engine available to police departments was a iteration of the 318 ci V8, capable of an 18.16 second
quartermile in period testing - slower than the 90-hp
Volkswagen Rabbit GTi. This generation of the Gran Fury sold in respectable numbers. However, despite having the same base prices as the Gran Fury (just under $12,000
USD for their final year), the Diplomat always outsold it, usually by several thousand units each year. The Chrysler Fifth Avenue's total sales were always more than that of the Gran Fury and Diplomat by far, even though it generally cost about $6,000
USD more. This last car to carry the Gran Fury nameplate remained largely unchanged for its 7-year run. Declining sales, a lack of promotion, and technical obsolescence—the platform dated back to the 1976
Plymouth Volare and
Dodge Aspen—eventually contributed to the model's demise in early 1989. That year, a driver-side airbag became standard; this would be the last RWD Plymouth until the introduction of the
Prowler. While Dodge offered the 1990
Monaco, and later the 1993
Intrepid, Chrysler never replaced the Gran Fury with any other large car in the remainder of the Plymouth brand's existence until its demise in the 2001 model year.
