Cadillac DevilleModels & History 1990
The best-selling luxury automobile in America, the 1990 version of the deVille, was powered by a more powerful 4.5-liter V-8 engine. Its horsepower was increased from 155 to 190, while torque moved up from 240 to 245 lb.-ft. A new windshield wiper system with enhanced overall operation was adopted. Features that were previously optional that were now standard on the deVille consisted of
- center front seat armrest with a flip-open storage area
- door edge guards
- manual driver and passenger seat recliners
- a leather-trimmed steering wheel rim
- a driver’s side supplemental inflatable restraint (S.I.R.) system.
Five new exterior colors were offered:
- slate gray
- light auburn
- dark auburn
- medium slate gray
- dark slate gray.
A total of 15 exterior colors were available. Sable black was now offered as monotone. Replacing the academy gray lower accent molding was medium slate gray. A long list of advances and improvements highlighted the 1990 deVille interior. Two new Primavera cloth colors, slate gray and dark auburn, were introduced. A total of five colors were offered. These two colors were also available in the Sierra grain leather trim, joining six carryover colors from 1989.New standard driver and vanity mirrors with mirror covers were also installed. Also standard was a front seat “clamshell” armrest with a deeper storage area to accommodate both compact discs and cassette tapes. A removable coin holder was located on the driver’s side inside area of the armrest. The cup holder now had a new lever feature. The front and rear floor mats were rubber-backed and available with optional retention needles. A new front seatback buckle anchor (on track) was used to provide increased convenience in locating the buckle from any position. The use of the S.I.R. resulted in the elimination of the steering wheel telescoping function.Standard on the de Ville was an upgraded acoustic package. A pass-key system that included a passive anti-theft system that disengaged the starter, fuel pump and ECM was also standard. The Express-Open Webasto Astroroof was improved to allow the roof window to open with a single one-second touch on the switch. The roof window could be stopped at any position by tapping the switch a second time.Changes in Cadillac’s engine for 1990 consisted of the use of a dual level intake manifold, lightweight pistons, larger valve cylinder heads, new magnesium valve covers and new BCM software. The optional cast aluminum lace wheels offered for the de Ville featured window areas of either silver or gray depending on the car’s lower accent molding color. The center cap display had a gray background. A chrome wreath and crest were used. The deVille’s overall ride characteristics were enhanced by improved vehicle structure. For Sedan de Villes intended for fleet use, a new coachbuilder and heavy-duty livery package was offered.
