covers), upholstery choices including Mark Cross leather (see below) and Yorkshire cloth, sound systems choice, 40-band CB radio, power moon roof, and the Frank Sinatra Edition package (see below). Unique for the Imperial was the first fully electronic digital instrumentation ever provided in a production-built American automobile. The Imperial's electronic information center was manufactured at Chrysler's Huntsville, Alabama Electronics Division, which was also a prime contractor in America's Redstone and Saturn Apollo space programs. Located in the center of the instrument panel were nine push-buttons the driver was to touch to operate Imperial's information center. The buttons were: 1) Mode-U.S./Met. A touch converts the reading on the speedometer, odometer and fuel displays to metric; 2) Clock-Date.; 3) Clock-E.T.; 4) Odometer-Trip.; 5) Odometer-Avg. Speed.; 6) Fuel-Range.; 7) Fuel-Present.; 8) Fuel-Trip.; 9) Reset-Zero. The instrument panel displayed an electronic blue-green VFD readout which also featured gear selection. The Imperial for this year offered a choice of eleven exterior colors (Sterling Silver Crystal Coat; Day Star Blue Crystal Coat; Nightwatch Blue; Light Auburn Crystal Coat; Mahogany StarMist; Light Seaspray Green Crystal Coat; Spice Tan Starmist; Manila Cream; Morocco Red; Pearl White; Formal Black), and six cloth and seven leather interior colors (Dark Blue; Green; Red; Mahogany; Heather; Cashmere; White for leather only). In all, thirty-five interior color and trim combinations were available. 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 the 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 1981 models were retrofitted under warranty (or later on owner initiative)
