Chronology
Predecessor	Chrysler Imperial Crown

Imperial was the Chrysler Corporation's luxury automobile brand between 1955 and 1975, with a brief reappearance from 1981 to 1983.

The Imperial name had been used since 1926, but was never a separate make, just the top-of-the-line Chrysler. However, in 1955, the company decided to spin Imperial off as its own make and division to better compete with its North American rivals, Lincoln and Cadillac. Imperial would see new or modified body styles introduced every two to three years, all with V8 engines and automatic transmissions, as well as technologies that would filter down to Chrysler corporation's other models.

For the 1955 model year, the Imperial was launched and registered as a separate marque (make), apart from the Chrysler brand. It was a product of the new Imperial Division of Chrysler Corporation, meaning that the Imperial would be a make and division unto itself, and not bear the Chrysler name. Chrysler Corporation sent notices to all state licensing agencies in the then-48 states that the Imperial, beginning in 1955, would no longer be registered as a Chrysler, but as a separate make . Chrysler introduced Forward Look Styling by Virgil Exner, who would define Imperial's look (and the look of cars from the other four Chrysler divisions) from 1955 to 1963. Even as early as in 1954, Chrysler Corporation ads at the time began to visibly and consciously separate The Imperial from the Chrysler Division car line in the eyes of the public, to prepare for the big change coming in 1955. Once the "Imperial" brand was introduced, Cadillac no longer used the "Imperial" name for its top-level limousines starting in 1955.

The 1955 models are said to be inspired by Exner's own 1952 Chrysler Imperial Parade Phaeton show cars (which were themselves later rebodied to match the 1955-56 Imperials). The platform and bodyshell were shared with that year's big Chryslers, but the Imperial had a wheelbase that was 4.0 inches (102 mm) longer, providing it with more rear seat legroom, had a wide-spaced split eggcrate grille, the same as that used on the Chrysler 300 "executive hot rod", and had free-standing "gunsight" taillights mounted above the rear quarters, which were similar to those on the Exner's 1951 Chrysler K-310 concept car. Gunsight taillights were also known as "sparrow-strainer" taillights, named after the device used to keep birds out of jet-engines. Such taillights were separated from the fender and surrounded by a ring and became an Imperial fixture through 1962, although they would only be free-standing in 1955-56 and again in 1961-62. Two "C-69" models were available, including the two-door Newport hardtop coupe (3,418 built) and pillared four-door sedan (7,840 built), along with an additional "C-70" Crown limousine model (172 built). The "FirePower" V8 engine was Chrysler's first-generation Hemi with a displacement of 331 cu in (5.4 L) and developing 250 brake horsepower (186 kW). Power brakes and power steering were standard, along with Chrysler's "PowerFlite" automatic transmission. One major option on the 1955 and 1956 Imperials was air conditioning, at a cost of $535. Production totaled 11,430, more than twice the 1954 figure, but far below Lincoln and Cadillac.
