The IAD Royale was a concept car built in 1988. The Royale was intended for business people and entrepreneurs and was a study in passenger comfort and space. The interior developed between IAD and Phillips was finished off in white leather. The car featured centrally-mounted revolving rotary keypads, duplicated front and rear, replaced conventional controls for the in-car entertainment system, information center, and navigational system.
Based on a stretched Subaru body, the Royale also incorporated an LED screen integrated into the rear lights, which displayed information relevant to road safety.
