Imperial was the Chrysler Corporation's luxury automobile brand between 1955 and 1975, with a brief reappearance in 1981 to 1983, and a second reapearance from 1990-1993.

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, and European luxury sedans such as the Mercedes-Benz 300 Adenauer, the Mercedes-Benz 600, and the Rolls-Royce Silver Cloud. Imperial would see new 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 it's top-level limousinesstarting in 1955.

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 1962. Models included a two-door Newport hardtop coupe (3,418 built) and a four-door sedan (7,840 built). The V8 engine was Chrysler's first-generation Hemi V8 with a displacement of 331 cu in (5.4 L) and developing 250 brake horsepower (186 kW). Power brakes and power steering were standard. 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.

1956

The 1956 models were similar, but had small tailfins, a larger engine displacement of 354 cu in (5.8 L) with 280 brake horsepower (209 kW), and a four-door Southampton hardtop sedan was added to the range. 10,268 were produced. With a wheelbase of 133.0 inches (3,378 mm), longer than the previous year's by 3.0 inches (76 mm), they had the longest wheelbase ever for an Imperial. This also contributed to an increase in their overall length to 229.6 inches (5,832 mm), making them the longest non-limousine post WWII American cars until the advent of the Imperials of the "Fuselage Look" era later in the 1970s.

1956 was the year that Chrysler introduced the push button PowerFlite automatic transmission; Packard also introduced a similar system called the Touchbutton Ultramatic in the Imperial's competitor, the Packard Caribbeanand the Patrician.

On April 28, 1955, Chrysler and Philco announced the development and production of the world's first all-transistor car radio, the Mopar model 914HR. It was developed and produced by Chrysler and Philco and was a $150.00 "option" on the 1956 Imperial car models. Philco manufactured the Mopar 914HR starting in the fall of 1955 at its Sandusky Ohio plant, for Chrysler.

For the 1957 model year, the Imperial received its own platform, setting it apart from any other division of Chrysler. This would last through the 1966 model year. Imperials during this period were substantially wider, both inside and out, than other Mopars with front and rear shoulder room equal to 64.0 in (1,626 mm) and 62.0 in (1,575 mm) respectively. The front seat shoulder room measurement remains an unsurpassed record for Imperial and would remain the record for any car until the 1971–1976 GM full-size models. Exterior width reached a maximum of 81.7 in (2,075 mm) for 1961–1963, which remains the record for the widest non-limousine American car. After Lincoln downsized for 1961 this generation of Imperial had no real competitor for the title of largest car for the remainder of its decade-long lifespan.

One advantage of Imperials of this vintage was their strength; their crashworthiness got them banned from most demolition derbies for being too durable and too tough to take down. Unlike the rest of the Chrysler Corporation makes (Chrysler, De Soto, Dodge and Plymouth), that began unibody construction for 1960, the Imperial retained separate full perimeter frames for rigidity through the 1966 model year. These substantial frames had a box cross section with crossmembers forming an "X". The drive shaft passed through a hole in the "X" frame. The emergency brake gripped the drive shaft, and was not connected to the rear drum brakes prior to the 1963 model year.

Another advantage was that Imperial, and all Mopars, received "Torsion-Aire" suspension for 1957. Torsion-Aire was an indirect-acting, torsion-bar front suspension system which reduced unsprung weight and shifted the car's center of gravity downward and rearward. Torsion-bar suspension on the front combined with multi-leaf springs on the rear provided a smoother ride and improved handling.

1957

The 1957 model year was based to an even greater degree on Virgil Exner's "Forward Look" styling (also used on other full-size Chryslers of the period). It featured a complicated front end (similar to Cadillacs of the period) with a bulleted grille and quad headlights, tall tailfins, and Imperial's trademark gunsight taillights. For the first time on an American car curved side glass was used. The Hemi engine was available for the first two years that was enlarged to 392 cu in (6.4 L). Power seats and dual exhaust were made standard across the line. A convertible was available for the first time on an Imperial and available in the mid-range Crown series. Sales were helped by Exner's "ahead of the competition" styling, with 1957 becoming the best-selling Imperial model year ever. 37,593 were produced, but Cadillac by contrast sold over 120,000 cars in 1957. Quality control also slipped considerably, a consequence of the second total redesign in two years.

Starting in the 1957 model year, Imperials were available in three levels of trim: standard Imperial Custom, mid-range Imperial Crown, and the new top-of-the-line Imperial LeBaron (a reference to LeBaron, Carrossiers). The custom-built Imperial Crown limousine was also offered. Through the late 1950s and into the early 1960s styling would continue to become "Longer, Lower, Wider", with the addition of some of the wildest fins on a car. The "FliteSweep Deck Lid", a fake continental tire bulge, was an option for 1957 through 1961 and again in 1963 (due to demand). It was shared with contemporary Mopars, including the Valiant. Exner's love of this feature extended back to early-fifties concept cars like the 1953 Chrysler D'Elegance.

1958

Styling changes for 1958 were limited to the front grille and bumper. Quad headlights became standard. The 1958 Imperial is credited with the introduction of cruise control, which was called "Auto-Pilot", and was available on the Imperial, and on Chrysler New Yorker and Windsor models. Power door locks were another new option. Sales slipped to 16,133 in a recession year. Dealers were frustrated with buyers referring to the cars as a "Chrysler Imperial", which inhibited sales as Chrysler was not seen as having Cadillac or Lincoln's prestige. It didn't help that Imperial continued to be sold at Chrysler dealerships, instead of standalone dealers, although it did have a separate "Imperial" dealership sign. 

1959

Production was moved from the traditional Jefferson Avenue Assembly plant in Detroit to an exclusive facility on Warren Avenue, north of the Jefferson Avenue factory. Other than a toothy new grill and revisions to side trim little changed in terms of exterior styling for the 1959 model year. A new option was the "Silvercrest" roof which featured a stainless steel front with a rear canopy that could be ordered either in any of the basic car colors or in the "Landau" version which had a black canopy with the appearance of leather. Another new option was swivel out front seats that were part of the six way electric front bench seat. Manually activated by a handle for this introductory year, for 1960 and 1961 the seats would automatically swivel when the front door was opened activated by a cable. The Hemihead engine was replaced with the less expensive 413 cu in (6.8 L) Wedgehead engine that nevertheless had more horsepower and weighed 101 lbs less, improving the power-to-weight ratio. For the model year 17,710 Imperials were produced, ahead of Lincoln, as the Packard luxury brand withdrew from the marketplace.

While many critics of automobile styling rate the 1955 through 1959 Imperials highly, the design of the 1960–1963 period is more controversial. At that time, Exner was increasingly struggling with the Chrysler president and board. "It was during 1962 Exner was dethroned as president of design in Highland Park. His successor was Elwood Engel, lured away from Ford to lead Chrysler Corporation along a more conventional path. Exner continued as a consultant through 1964, after which he had no further involvement." This source also states, "When he was good, he was very good ( re: styling). When he was bad.... it was the epitome of excessive design. Sales dropped off and the board stepped in." Exner's son went on further, in a 1976 interview, "it was time for a change. Their image needed changing. Dad was a great designer and he was always ahead of his time. He gained more freedom from Chrysler in his designs of the modern Stutz." This same source gives blow-by-blow accounts how Chrysler Corporation was revived through corporate changes in leadership. "But on the product front, the influence of Tex Colbert (ousted President of Chrysler in 1961) and Virgil Exner was still present, and it wouldn't be entirely washed away until 1965".

Despite the annual styling changes, all 1960-63 models featured a similar space age dashboard. The steering wheel was squared-off at top and bottom, designed for better leg room and view through the windshield in the straight ahead position. Dashboard lighting was electroluminescent, which used no incandescent lamps: electricity running through a five-layer laminate caused the phosphorescent paint to glow in the dark. Chrysler called it "Panelescent", and it was shared on some Chrysler models. The effect was eerie and surprisingly modern, with its glowing green face and bright red needles. The 1960-63 models were also united by a distinctive side trim that started above the headlights and that ran at a slight downward angle almost to the end of the rear fender (except in 1963 when it would actually wrap all the way around the rear of the car) that was undercut by a slight indent in the sides from the front until just before the rear wheel housing.

More importantly, but perhaps less obviously, a significant change in the car's proportions had occurred between the 1959 and 1960 model years. Although, at 226.3 inches, the 1960 Imperials were exactly the same length as the previous year, the whole body had been shifted forward, with a 2.1 inch reduction in the rear overhang, and a corresponding increase at the front. This led to a look that, due to a relatively smaller rear deck and more expansive front hood, was closer to Exner's classic car era ideals, and it would persist, by one means or another, for the remainder of Imperial's existence as a separate marque.

1960

The 1960 Imperial adopted wildly exaggerated styling, featuring front fascia with a swooping bumper, gaping mesh grille, giant chrome eagle, and hooded quad headlights, and tall rear fins. Soaring fins had bullet style tail lamps at the peak of the fin, with a chrome ring surrounding it. The grille and bumper on the front of the 1960 used large pieces of heavy chrome, and the 'furrowed brows' of the fenders over the double sets of headlights gave the car a ponderous look. In common with most other 1960 Chrysler products, the Imperial featured the new "High-Tower" seat with the driver-side back individually contoured and raised above of the rest of the front seat for increased driver comfort and shoulder support. This would last through the 1962 model year. Also for 1960, Imperial changed back to 15 inch diameter wheels from the 14 inch diameter wheels that had been standard since the 1957 model. Imperial LeBarons now featured a distinctive smaller "formal rear window" for greater rear seat privacy. Sales increased to 17,719. Imperial again finished ahead of Lincoln, but never did so again. While the rest of Chrysler's lineup adopted unibody construction, Imperial retained its body on frame construction.

1961

The 1961 model year brought a wholly new front end with free-standing headlights on short stalks in cut-away front fenders (a classical throwback favored by Virgil Exner, used commonly in the 1930s Chryslers. He would continue his look with the modern Stutz), and the largest tailfins ever. Inside, the Imperial gained an improved dash layout with an upright rectangular bank of gauges. The pillared four-door sedan was cancelled and would not return until the 1967 model year. With the downsizing of Lincoln, at 227.1 inches (later increased to 227.8 inches in 1963), the Imperial would once again be the longest non-limousine car made in America though 1966. Sales fell to 12,258, the result of bizarre styling and continued poor quality control.

1962

The tailfins were largely truncated in 1962, topped with free-standing gunsight taillights, but these were elongated, streamlined affairs. The front grille was split, as in 1955-56, and a large round Eagle hood ornament was fitted for the first time. The 1962 models had a new, slimmer TorqueFlite A727 automatic transmission, which allowed a smaller transmission "hump" in the floor. This provided greater comfort for passengers in the center seat up front. Dual exhaust was now only standard on convertibles. 1962 also marked the closing of Imperial's dedicated assembly plant. All later Imperials were once again built in the same Jefferson Avenue facilities in Detroit as Chryslers, as sales were insufficient to maintain a separate facility. 1962 production totaled 14,337. Shortly before leaving Chrysler, Virgil Exner had planned for a smaller Imperial to go along with the downsized 1962 Mopars, but the idea never went anywhere.

1963

The 1963 models saw the split grille disappear again, replaced by a cluster of chromed rectangles, and the taillights were now inside the rear fenders, in ordinary fashion, for the first time. In addition, the designers redesigned the rooflines of Custom and Crown, two and four door models to be more squared off with thicker c pillars. 1963 models were the last Virgil Exner–styled Imperials, however Elwood Engel began applying some of his own touches to them, especially in the form of the redesigned base and Crown roofs. LeBaron roofs remained the same with formal styling and closed in rear window. 14,121 cars were produced for 1963.

In 1961, Chrysler scored a coup by hiring Elwood Engel away from Ford, where he had designed the 1961 Lincoln Continental. Engel's design themes at Chrysler were a major departure from the fins of Virgil Exner, and instead featured a more familiar three-box design, but with more extreme rectilinear styling. And, at first glance, the total re-styling of the Imperial in 1964 was thought to strongly resemble Elwood Engel’s previous efforts for the 1961 Lincoln Continental. Both cars shared clean, slab-sided body panels, thick C-pillars, and a chrome molding outlining the top of the fender line. However, Engel used subtle curves and parallelogram angles to give the Imperial a distinct and novel look.

1964

The 1964 Imperials were the first designed entirely by Mr. Engel. Predictably, they bore a strong resemblance to the Lincoln Continental. The dashboards seemed more conventional because the squared-off steering wheel and electroluminescent dash lighting were gone. However, there remained the ribbon-style speedometer. A split grille returned after one year's absence, inspired by the 1955 model's appearance, and the faux spare tire bulge atop the trunk lid gave way to a squared-off protrusion at the rear, carrying downward to the rear bumper. A large boss in the center of it was actually the fuel filler door, covered with a large Imperial Eagle. Horizontal, spear shaped housings hold a taillight and back-up light. Heat and defrost, always a popular option, were now standard.

The base Imperial Custom model was now gone; the cars were now available as a four-door hardtop in the Crown or the LeBaron levels of trim, or as a two-door hardtop or convertible in the Crown level of trim. As a result, power windows were now standard on all Imperials. Imperial Crown coupes adopted the smaller style LeBaron "formal rear window" that had been introduced in 1960, and both body styles could now be ordered with a vinyl roof. With 23,295 produced, 1964 was Imperial's second best sales count ever. A padded dash, power seats, power steering, power brakes, and head rests were standard on the convertible. A new option this year was an adjustable steering wheel.

Tom McCahill, an automobile critic with a reputation for colorful metaphors, quipped that Imperial "cornered at speed flatter than a tournament billiard table", unusual for a car of its prodigious weight and extreme dimensions. McCahill became a loyal customer, buying a new Imperial yearly through 1962. His visible and enthusiastic endorsement helped Imperial forge a reputation as the "driver's car" among the big three luxury makes.

And as McCahill observed in 1964:

This is what I told them in California. When I hit the road with hundreds of pounds of baggage, typewriters and testing equipment, I’m not out there just to have fun. I want to get from here to there, which may be thousands of miles away, with as much comfort as possible. Besides, Boji now demands comfort. So does my wife.

I've been on some pretty fancy trains, including private cars, and to this writing, I have never found anything quite as comfortable or more capable of getting me to my destination as the '64 Imperial LeBaron. It's a great automobile.

 

1965

Changes for 1965 were largely confined to the front fascia and to trim, and replacement of the push-button automatic transmission gear selection system with a more conventional steering column-mounted shift lever. The split grille was gone, replaced by a large chromed crossbar and surround, and the headlights were inset into the grill behind glass covers (similar to that year's Chrysler 300 and New Yorker models) with etched horizontal lines imitating the grill. As pointed out by the sales literature, 100-year-old Claro Walnut trim was added to the interior. Production totaled 18,409.

1966

This was the final year for the Imperial platform that was first introduced in 1956 for the 1957 model year. All subsequent years through 1966 used this same basic platform with annual changes to the body sheetmetal. However, the Imperial still used the wrap-around windshield that had been dropped by most other makes for entry and exit room when they almost all simultaneously downsized for 1961.

The 1966 model year saw a change to an egg-crate grille. The glass headlight covers lost the etched lines but gained twin 24k gold bands around the perimeter. The trunk lid bulge became more squared off with a smaller Imperial script off to the side. The back-up lights were moved to the lower bumper, nearly doubling taillight size. The Claro Walnut trim that had been introduced the previous year was used more extensively and would be replaced the following year. The 413 cu in (6.8 L) engine that had been standard since 1959 was replaced with a 350 hp (261 kW; 355 PS) 440 cu in (7.2 L) engine.

Production totaled 13,752. There was a 1966 LeBaron that was presented to Pope Paul VI at the UN in New York for his use. Also this year, Imperial was the basis for "The Black Beauty," a rolling arsenal on the ABC-TV series The Green Hornet, starring Van Williams and Bruce Lee. A black Imperial of this year would also be restored as a wedding anniversary gift for Richard "The Old Man" Harrison on the History Channel show, Pawn Stars.

With the exception of the introduction of a shorter wheelbase and unit body construction, Imperial styling was not radically changed for the 1967 and 1968 models. The new body maintained the themes established by Engel for the 1964–1966 models. Imperial switched from the body-on-frame platform (D-body) to a unibody platform (C-body platform used in other full size Mopars.) While Imperial's front K member was 3.0 inches (76 mm) longer than a Chrysler's, dimensions behind the front fenders were similar. One reason for the change was that Chrysler had gained experience with unibody construction and was ready to apply it to the company's flagship line.

The economic component was that the switch to the C-body was less expensive than maintaining a separate platform for Imperial, which was increasingly difficult to justify given Imperial's relatively low sales volume. The new platform resulted in a significant reduction in weight as well as in exterior and interior dimensions. With the partnership gone between Ghia and Chrysler, limousines based on the Imperial were produced by Ambruster-Stageway of Fort Smith Arkansas. The limousines were "sectioned" between the front and back doors with a 36" insert (based on factory sheetmetal) that allowed two rear-facing seats and a small console/bar in between. The limousine conversions were longer than the earlier Ghia cars, and longer than the Cadillac Series 75 limousines.

1967

Imperial shared the unibody platform with other full-sized Chryslers but retained a unique bodyshell. The styling kept the overall straight-line, sharp-edged Engel theme, but there were many detail changes intended to make Imperial look less like Lincoln and more into its own territory. The spare tire bulge was completely gone from the rear, although the boss remained. The practically full-width taillights spread out from it, straight, but ended before chrome-tipped rear wings. The front end was somewhat similar to 1966's, although the glass lamp covers were gone. A base Imperial model, simply called Imperial, returned for the first time since 1963, complementing the Crown and LeBaron levels of trim. It contained the convertible, which had previously been a Crown, and the first four-door pillared Imperial sedan since 1960. Dual exhaust was no longer standard on the convertible. The only way to get it was to order the "TNT" version of the 440 engine, an option that promised more power.

An option on Crown coupes was the Mobile Director. Essentially the front passenger seat turned to face rearward and a small table and high intensity light folded out over the back seat. The idea was that an "executive" could turn around and do work while being driven to the office, or he could sit behind the driver and a secretary could take dictation in the rear-facing front seat. The concept originated with the 1966 Mobile Executive Show Car that was an Imperial Coupe fitted with a telephone, Dictaphone, writing table, typewriter, television, reading lamp and stereo. Chrysler also used the reversed front seat idea in the 300X show car. Costing $597.40 ($317.60 in 1968), at a time when a Crown coupe started at $6011, it was a very expensive option. Thus a total of only 81 Crown coupes were ordered this way, and only a handful so equipped are known to still exist. The option was cancelled at the end of the 1968 model year. Sales increased to 17,614.

1968

The 1968 Imperial was little changed from the previous year. The grille changed to a brightly chromed one with thin horizontal bars, split in the middle by vertical chrome and a round Imperial Eagle badge. The cornering lamp lenses were now covered by matching grilles. At the rear, the horizontal bars over the taillights remained, but the gas filler door pull was changed to a cast metal eagle instead of a round knob containing a plastic emblem. All 1968s came with a Federally mandated energy absorbing steering column. The base level of trim was cancelled after only one year and the convertible and four-door sedan became part of the Crown level of trim. This was also the last year for the Imperial convertible. A total of 15,367 Imperials were sold in 1968.

The "Fuselage Look" was how Chrysler described its new styling for 1969. Instead of the square lines of 1964-1968 models, the new Imperials featured rounded "tumblehome" sides, bulging at the belt line, and tucking in down to the rocker panels. The new styling not only made the cars look longer and wider, it also surrounded the passengers in a hull-like fashion, similar to an aircraft, hence the reference to "fuselage". The curved side glass, which had been pioneered in America by Imperial for its 1957 model, had a much tighter radius, while the increased curvature of the bodysides permitted the window frames to be moved outboard at their bases, resulting in an increase in shoulder room without an increase in overall body width compared to the previous C-body. In fact, front and rear shoulder room increased from 59.4 in (1,509 mm) to 62.7 in (1,593 mm) on 4-door hardtops.

To reduce development and tooling costs, and bring overall expenditures more in line with actual sales, Imperial was forced to share much of its bodyshell with Chrysler for the first time since 1956. Consequently, front and rear doors, quarter panels, decklids, glass, and roofs were common with the entry-level Chrysler Newport. In other respects, however, little had changed; construction was still unibody, the wheelbase was still stretched 3.0 in (76 mm) longer than a Chrysler's in front of the passenger section, the engine and transmission were the same, and the torsion barfront suspension was still used.

1969

In keeping with the times, the look was sleeker, with a reduced, more subtle level of trim. For the first time, the lights were hidden behind doors, giving a fashionable at the time full-width grille look using "loop" bumpers, primarily used on the Lincoln Continental. Only this year the Imperial featured sequential turn signals. 1969 was the final model year for pillared sedans, and it was also the first year for the Imperial LeBaron coupe. At 229.7 inches Imperial would once again be the longest non-limousine car made in America, and would remain so through 1973 when it would set the post WW II record for non-limousine car length. 22,083 were produced for Imperial's third best ever year. Ambruster-Stageway of Fort SmithArkansas continued with limousine conversions using the 1969-71 sheetmetal. Twelve total conversions were delivered over the three years, including one for then New York governor Nelson Rockefeller.

1970

The 1970 models differed only in minor ways. The grill pattern changed to a larger eggcrate design; the front cornering lamps were now rectangular instead of the "shark gill" pattern of 1969 models. A wide chrome strip was added at the rocker panels, vinyl side trim was made optional, and (for this year only) the fender skirts were gone. It was the final year for the Crown series; afterwards Imperial would have only two models, a LeBaron hardtop sedan and coupe. 11,822 of the 1970s were produced.

1971

For 1971, the Imperial Eagle at the front of the hood was gone, replaced by the word IMPERIAL; the deck lid badge said, for the first time, "IMPERIAL by Chrysler". The 1971 Imperial is notable for being the first production car in America with a 4-wheel Anti-lock braking system (ABS) from Bendix, a rarely selected option at that time. 11,569 1971 Imperials were produced.

Although the vinyl top was standard, for a short time a unique paisley-patterned vinyl top in a burgundy color was available as an option on burgundy-painted cars. It has been rumored that this top had actually been overprinted on waste "Mod Top" patterned vinyl, which had been available on some 1969 and 1970 model year Dodge and Plymouth cars, but according to Jeffrey Godshall, a Chrysler designer and frequent contributor to the magazine Collectible Automobile, this was not the case. With exposure to the elements, the burgundy overprint faded, and the pattern began to show through in a purple "paisley" pattern. Chrysler replaced many affected tops with either white or black standard vinyl, but some survive.

1972

The sheetmetal was completely new for the 1972 model year, although the styling was an evolution of the previous fuselage style. The 1972 model appeared bigger and heavier all around in comparison to the 1969-1971 models and featured a somewhat more rounded side profile without a character line down the side and chrome trim on the top seams of the fenders from the rear windows forward. The front fascia was all new and imposing-looking, and the back featured vertical teardrop taillights for the first time, while the rear side marker lights were in the form of shields with eagles on them. Sales increased to 15,796.

1973

The 1973 model year saw new federal bumper standards to prevent damage. This meant the Imperials gained large rubber over-riders front and rear, adding 5.8 inches (147 mm) to the car's length, making it the longest production car in North America for that year and the longest postwar (non-limousine) production car at 235.3 inches (5,977 mm). As 1973 was in general a good year for the auto industry, 16,729 of the 1973 Imperials were built and sold. Two all-black LeBaron sedans were delivered to the US Secret Service, who then turned them over to Hess and Eisenhardt, who converted them into limos for Presidential use. Both cars were used as late as 1981, and carried Ronald Reagan and his staff to Capitol Hill for his Presidential Swearing-in ceremony in January 1981.

Chronology
Successor	Chrysler New Yorker Brougham

On the eve of final plans for the 1974 model year things looked bleak for Imperial. The marque had lost its exclusive assembly plant in 1962. It had lost its unique platform for 1967. Then for 1969, it lost its unique bodyshell. Mention of the Chrysler name returned in 1970 after Imperial having been a separate marque for years. The 1973 model year appeared to be the end of the road for Imperial.

Chrysler had planned on quietly discontinuing the Imperial at the end of the 1973 model year. Without its own unique bodyshell, it would be difficult to compete with Cadillac and Lincoln, which had their own unique bodyshells. Sales were likely to remain low, as image and appearance were an important part of luxury car appeal. And, in turn, without sales, it seemed there was no way Chrysler could afford to build an Imperial with a unique appearance.

A front end design, which had been envisioned for the next Imperial by Chrysler/Imperial exterior studio senior stylist Chet Limbaugh, came to the attention of Elwood Engel. Engel showed the design to Chrysler president John Riccardo and convinced him to use it on an Imperial. Except for the front end clip and trunk lid, to save money it would use all the same body panels as the Chrysler New Yorker, and, for the first time in its history as a separate marque, it would have the same wheelbase. But the car would have Limbaugh's unique new "waterfall" grille design which featured thin vertical chrome bars, separated by a body-colored band running through the center, and which started on top of the nose and flowed down.

1974

With the full effects of the 1973 oil crisis being solidly felt, a bad year for the U.S. economy (and the auto industry as well) was in place for 1974. This was Chrysler's 50th anniversary year and the final redesign of the full-size Imperial. The 1974 Imperial was the first regular American passenger car to offer 4-wheel disc brakes since the 1949–1954 Chrysler Imperials, the 1950–1952 Crosleys and the Chevrolet Corvettes that started featuring them in 1965. The Imperial's ignition system was electronic, another first in the market, as was the optional burglar alarm. In addition to the two regular 1974 LeBaron models, a 50th Anniversary 2-door LeBaron Crown Coupe was also produced, finished in Golden Fawn; only 57 were built, making a grand total of 14,483 Imperials produced for the model year. While sales were down from 1973, Chrysler was pleased with the sales of the Imperial line, given the poor economy that year.

1975

For 1975, other than an enhancement to the waterfall grille, the front bumper and a few detail improvements, little changed. This was to be the last model year of the independent Imperial marque, with only 8,830 1975 models sold. The last Imperial, a LeBaron sedan, rolled out of the factory on 12 June 1975. However, only the name disappeared, as the same basic car was offered, rather more cheaply (the Imperial feature of 4-wheel disc brakes was discontinued). For model years 1976 through 1978, the car was known as the Chrysler New Yorker Brougham. Justifying the price differential over the full-size Chrysler had become increasingly hard to do as the cars became more and more similar over the years to save costs, and in turn the costs of maintaining and marketing a separate, poorly selling marque were possibly just too high. Also, the 1973 oil embargo had turned buyers towards smaller more fuel efficient cars, a movement that had been building through the early-1970s as a result of rising fuel prices.

Predecessor	Chrysler Imperial Crown

Jacqueline Kennedy, standing near Robert F. Kennedy, about to enter her 1960 Imperial Crown limousine after the funeral of President John F. Kennedy at St. Matthew's Cathedral.

For 1955 and 1956, a Imperial Crown limousine model was also offered. With an extra 19.5 in (500 mm) and 16.5 in (420 mm) of wheelbase in 1955 and 1956 respectively, and seating eight (three in the front including the driver, three in the rear, and two on rearward-facing fold-down jump seats), these replaced the long-wheelbase offerings in all Chrysler marques. Only 172 were built for (model year) 1955 and 226 for 1956. They were the last Chrysler-branded limousines built entirely in Detroit.

For 1957 through 1965, long-wheelbase Imperial Crown cars would be finished by Ghia in Italy. The earlier models used two-door hardtop bodies mounted on the more rigid convertible chassis; these would be shipped across the Atlantic, cut apart, lengthened by 20.5 inches (521 mm) and reworked. Later models were built from four-door models to the same specification. Each took a month to build and carried a high price for the time ($18,500 in 1963-64). They sold poorly against the Cadillac Series 75 that was less expensive ($9724–$9960 in 1963-64), and had an established reputation among limousine buyers, as well as against competing coachbuilders building on the Cadillac commercial chassis. A total of 132 Imperial Crowns were manufactured for Chrysler by Ghia over 1957-65. An interesting oddity is that all 10 Ghia built Imperial Crowns sold during the 1965 model year were 1964s with 1965 exterior styling, and consequently had pushbutton gearshifts. At about 6,200–6,300 lb (2,800–2,900 kg) curb weight the 1957-65 Ghia built Imperial Crowns are the heaviest standard production cars sold by an American firm since the 1930s.

Throughout her husband's term as U.S. President, Jacqueline Kennedy's personal car was a Ghia built 1961 Imperial Crown with 1960 model year styling. The car figured prominently in her various duties as First Lady. In President John F. Kennedy's funeral procession on November 25, 1963, near the front of the motorcade, carrying Jackie and her children, was her Imperial Crown. In 1963, the Imperial Crown limousine saw a new competitor from Europe called the Mercedes-Benz 600 and the Rolls-Royce Phantom V, with the same level of luxurious attention shared with the Ghia-built Crown limousines.

Nelson Rockefeller, Vice President of the U.S. during the term of President Gerald Ford, also owned a 1960 Imperial Crown. It is one of 17 limousines made by Ghia in 1960, and the only one that year with blind rear quarter treatment.

In the 1974 movie The Godfather Part II, a black Ghia built 1958 Imperial Crown was used by Michael Corleone (played by Al Pacino) while at the family compound near Reno, Nevada.

Imperial limousines (1966–1983)

While the "Imperial Crown" limousines ended in 1965, Imperial limousines continued to be made by other coach builders. After the last ten Ghia built Imperial Crowns were completed, Ghia sold its tooling to Barreiros Coachbuilders of Spain. Barreiros built ten limousines, much like those built by Ghia and, similar to the last ten built by Ghia, built 1965s with 1966 exterior styling, but with two inches longer wheelbase. Build quality was poor by comparison, with the cars famous for having a wiring harness made from wires of the same color.

For model years 1967 through 1971, a total of 27 Imperial limousines were produced by Stageway Coachbuilders (ASC) of Fort Smith, Arkansas on a 163.0 in (4,140 mm) wheelbase, and were justifiably advertised as the largest luxury automobiles in the world. Two 1972 models with 1973 model year grills were built by the Hess and Eisenhardt Company of Fairfield, Indiana for the United States Secret Service and were used by Presidents Nixon, Ford, Carter, and Reagan on his swearing-in day. One 1974 model year Imperial was produced into a limo also by ASC. The final Imperial limousines were 1981–83 bodied cars, two of which were stretched by 24 inches (610 mm) and five were lengthened by 36 inches (910 mm).

The early 1980s Imperial was an attempt to reinvent the Imperial as a personal luxury car. This came about after Lee Iacocca took the helm at Chrysler, as he had been instrumental in creating the successful Lincoln Mark series for this market while he was at Ford in the late 1960s. Although the company was facing bankruptcy, Iacocca decided that "a new flagship would assure the public that Chrysler had a future." During the design of the car it was intended to be named Chrysler LaScala. However, when the car finally appeared, it was marketed simply as an Imperial, and the Chrysler name was not used.

For 1981, the top level sedan was the Chrysler New Yorker with the special "Fifth Avenue" trim package, introduced for 1979. The 1981 coupe was branded "Imperial" but with no model name, while the sedan was branded as "Chrysler."

The new Imperial was a smaller, two-door only package, sharing its wheelbase chassis with the second generation Chrysler Cordoba and Dodge Mirada. Neither a convertible nor a 4-door version was available, though conversions were made of both by 3rd party companies. The bustle-back appearance was an attempt at an early 1980s luxury car appearance that was briefly popular, with Chrysler drawing inspiration from its 1937–1939 Chrysler Imperial sedans.

The Imperial eagle logo was not used as it had been moved to the Chrysler LeBaron model in 1977. Instead it bore a Chrysler Pentastar hood ornament made of Cartier crystal.

Competing models such as the Cadillac Eldorado and the Lincoln Continental Mark VI had been downsized by 1981, so the Imperial was of comparable size to its competitors, and the Eldorado was at that time rising to the peak of its success. A marketing effort for the new model included commercials and magazine ads featuring singer Frank Sinatra, a personal friend of Iacocca. Sinatra even recorded special songs to promote the new Imperial. The Imperials carried a market-leading 24-month/30,000-mile limited warranty which covered all labor, maintenance, and parts (except tires).

1981

The 1981 Imperial came with a long list of standard features including air conditioning with thermostatic temperature control, electronic VFD dash (including odometer, speedometer, gear selection, gasoline-use calculator, and clock), power windows, power door locks, power seats, power outside mirrors, power trunk release, tilt steering column, automatic speed control, garage door opener, and other conveniences. Because of its high level of standard equipment there were virtually no options other than a cost-free choice of wheels (color-coordinated 'snowflake' cast aluminum wheels or steel wire wheel covers), upholstery choice (Mark Cross leather or Yorkshire cloth), sound systems choice, 40-band CB radio, power moonroof, and the Frank Sinatra Edition package.

1982

The Imperial continued to offer an extensive list of standard luxury and convenience items for 1982 although some changes were made. Imperial's "floating cushion" velour seats were replaced with ones of Kimberly velvet one-piece construction. New "Quartz-Lock" electronically tuned radios (ETR) were added to the options list while power moonroof was no longer available.

1983

Following significant price increases during the 1981 and 1982 model years, due in part to high inflation at the time, the Imperial's base price was cut back close to its original introductory level. The hood ornament, while similar in appearance, was changed from Cartier crystal to plastic. The Frank Sinatra Edition package was no longer available. A suspension upgrade Touring Edition package was added.

Overall, the sixth generation Imperial did not meet Chrysler management's sales and reliability expectations. It had innovations such as the fuel injection system and electronic instrument cluster, and Chrysler tried to use it as a showcase for technology and quality. Unfortunately the fuel injection system proved troublesome and many cars were retrofitted under warranty (or later on owner initiative) with carburetors.

The Imperial name would reappear for 1990, but as the flagship Chrysler Imperial model.

Powertrain

The 318 cu in (5.2 L) V8, with a Chrysler-built throttle-body EFI system, was the only available engine. The automatic transmission was a wide-ratio TorqueFlite equipped with lock-up torque converter, with the final drive ratio 2.2:1 in 1981 and 1983; 2.4:1 in 1982.

Special trims

Frank Sinatra Edition

The Imperial had an unusual distinction for 1981 as it was offered with an optional special edition named after a celebrity. The Imperial fs was a rare example of automotive history, as it was one of only a handful of regular production cars bearing a celebrity's name. This limited edition Imperial was available only in Glacier Blue Crystal paint - Chrysler advertising claimed it matched the color of Sinatra's eyes - and had special fs (lowercase) external badging, with a large glovebox placard proclaiming "Frank Sinatra Signature Edition". Inside, 16 cassette tapes of Sinatra titles were presented in a specially made Mark Cross leather case. In the center console of the car there was also a special tray for 8 cassettes. 271 fs edition cars were manufactured. The "fs" cost $1,078.

Limousine

Aside from the fs edition available for purchase by the public, Chrysler president Lee Iacocca commissioned a 1982 Imperial converted by ASC (American Sunroof Corporation) outside Detroit, Michigan using the front doors from a 1979-81 Dodge St. Regis sedan into a limousine with a 36 in (910 mm) stretch, and presented it to Frank Sinatra as a gift. A similar Imperial limousine also built by ASC is also used in the 1984 movie Cannonball Run II driven by Burt Reynolds and Dom Deluise, as well as the movies Sharky's Machine and Stick.

Cartier Crystals

All 1981 to 1983 model year Imperials had Cartier crystals strategically placed on the exterior opera lights and steering wheel, and each crystal displayed 'Cartier.' In addition, each Imperial came with a Cartier crystal key in the Mark Cross Gift Set.

Mark Cross Interior & Gift Set

All 1981 to 1983 model year Imperials had the interior designed by Mark Cross, maker of fine leather goods. The seating came in either Kimberly cloth or Leather. Upon purchasing a new Imperial, Chrysler shipped the new owner a Mark Cross Gift Set consisting of an umbrella, leather portfolio, leather key fob, uncut Cartier key, and a 'Sounds of Stereo' music cassette. These were exclusive Mark Cross items not available for sale in a Mark Cross show room.

NASCAR

A few race teams built NASCAR spec racecars with Imperial sheetmetal and raced them on the NASCAR circuit from 1981 through the 1985 season, though mostly only on the superspeedways. They were driven by Buddy Arrington, Rick Baldwin, Cecil Gordon, Phil Goode, and Maurice Randall. The cars did not distinguish themselves to any great degree, however a Buddy Arringtonowned and driven Imperial finished in sixth place in the summer 1982 race at Brooklyn, Michigan. The Imperial-based cars were used i
