as full instrumentation backed up by warning lights. In 1974 and 1975, separate brochures were published and separate Imperial signs still stood above the dealerships, and the Imperial continued to feature unique features (such as hidden headlights as featured since 1969, optional antilock brakes as offered since 1971, and standard four-wheel disc brakes in both 1974 and 1975), the wheelbase was reduced to the same 124" as other big Chryslers. Although there were no Imperials produced between 1976 and 1978, the styling that was previously used for Imperial was rebranded as the Chrysler New Yorker Brougham during this time. The rear disc brakes and optional antilock feature disappeared, but the exceptionally nice interiors, including rear reading lights with precision-ground lenses which did not shine on the windshield, and four cigarette lighters, continued mostly unchanged. 1981–1983 The Imperial marque was again resurrected for the model years 1981 through 1983 with a Malaise era two-door coupe based on the second-generation Chrysler Cordoba platform with the designation Series YS. All examples of the 1981–1983 Imperial used Chrysler's 318 cubic-inch V8 engine. All 1981 Imperials came standard with fuel injection, generating power of and 0-60 mph in 13.4 seconds, with a top speed of . 1990–1993 1990 saw a revival of the Imperial as a high-end sedan in Chrysler's lineup to replace the dated Fifth Avenue. Unlike the 1955–1983 Imperial, this car was a model of Chrysler, not its own marque. Based on the Y platform, it represented the top full-size model in Chrysler's lineup; below it was the New Yorker Fifth Avenue, and below that was the shorter wheelbase New Yorker. The reintroduction of the Imperial was two years after the Lincoln Continental was changed to a front-wheel drive sedan with a V6 engine. Other domestic competitors in this segment included the Cadillac Sedan de Ville/Fleetwood, Oldsmobile 98 and Buick Electra/Park Avenue, all of which shared General Motors' then-flagship C platform. Though closely related, the Imperial differed from the New Yorker Fifth Avenue in many ways. The Imperial's nose was more wedge-shaped, while the New Yorker Fifth Avenue's initially had a sharper, more angular profile (the New Yorker Fifth Avenue was later restyled to be more rounded front and rear). The rears of the two cars also differed. Like the front, the New Yorker Fifth Avenue's rear came to stiffer angles while the Imperial's rear-end had more contoured edges. Also found on the
