The 1987 Cadillacs, energized by what was regarded as “The new spirit of Cadillac,” as well as the introduction of the Allanté, featured engineering, convenience and styling refinements. A major effort was made to provide the 1987 Cadillacs with enhanced security features. All major body components were now tagged with the car’s individual vehicle identification number. Cadillac’s door-into-roof design was regarded as “an access through otherwise vulnerable window weatherstripping.” Another important security feature was a standard encapsulated door linkage system which enclosed all exterior-to-interior door handle hinges in single castings, thus rendering “slim-jim” devices ineffective. All models except the Cimarron were also offered with a theft deterrent system using the underhood horn as an alarm, and the front door lock cylinders and electric door locks to activate itself. The historic nature of the Allanté’s debut was established by John Grettenberger, who called it “General Motors’ new passenger car flagship.”

In 1987 Cadillac became the first automobile manufacturer to use multiplexed wiring to control lighting on a production automobile, the Allanté.
On January 7, 1987, Cadillac became the only General Motors car division with responsibilities for engineering and manufacturing in addition to its marketing and sales activities.
As a result, Cadillac had its own staff of engineers, designers, manufacturing personnel and marketing groups.
Cadillac General Manager John O. Grettenberger assumed responsibilities for engineering and manufacturing.
Robert L. Dorn, previously acting director of the former B-O-C (Buick-Oldsmobile-Cadillac) Detroit Product team, became general director of operations for Cadillac.
