Cadillac Allante Models & History 1990
The Allanté was available in two body styles for 1990. The Allanté convertible hardtop included both a convertible top and a removable all-aluminum hardtop. The new convertible was offered as a convertible only and did not include the hardtop. The standard and optional content of the two models was identical with the following exceptions: an analog instrument cluster was standard on the convertible and a no-cost option on the convertible hardtop. The digital instrument cluster standard on the convertible hardtop was an extra cost feature for the convertible. A pearl white exterior color was available at no charge on the convertible hardtop and an extra-cost option for the convertible.
The only exterior change for 1990 was the addition of a new beige metallic color. This provided a total of eight color choices for the Allanté. A new natural beige durosoft leather color was also offered. Other revised or new items for 1990 included a standard S.I.R. driver-side system, a smaller steering wheel with a thicker rim cross-section, new standard Delco-Bose compact digital disc player and an improved cellular telephone option. A Traction Control system providing increased steering ability and improved stability when accelerating as well as increased traction on slippery surfaces was standard.
