As Chrysler's top of the line, the Imperial began life in 1926. Although the "Imperial" name was used by other makes too as a body style (ie:
Cadillac Imperial Sedan), it became most commonly associated through the years with Chrysler.
Finally in 1955, the Imperial name became a separate marque, which lasted until 1975 when it was discontinued, although for the last couple years just before it was discontinued, a small "by Chrysler" tag appeared on the cars. The last few years of the Imperial line, only a couple body styles were available. The same style continued for several more years beginning in 1976 under the New Yorker name but without some of the standard features found on the Imperial.
The Imperial name was revived once again in 1981-1983 on a luxury personal coupe, again as a "Chrysler Imperial," that was based on the Volare platform, though it was distinctively different in appearance and very attractive. Because of poor sales, however, the name was discontinued once again after the 1983 model year.
Although not specifically covered by this site, it should be noted that yet again, the Imperial name appeared in 1990 though it was not much more than a trim package on the flagship Chrysler New Yorker. These cars differ in appearance from the New Yorker by having a vinyl top that extends to the "B" pillar, and they were slightly longer with a 5" addition to the wheelbase and increase of 10" overall from that of the New Yorker.
In 2006 Chrysler unveiled a new
concept Imperial (right) that appears to have much the flair of the Rolls-Royce Phantom. It features rear doors that are hinged at the back and a pillerless design. Unfortunately, Chrysler's new ownership has discontinued development of this car.
