Introduced at the 1987 Frankfurt Auto Show, the HFX (High Feature Experimental) Aerostar Ghia was a prototype of future minivan design. Two running prototypes were built from the collaboration of Ford and Ghia; both used the stock 3.0L Vulcan V6 and A4LD automatic transmission. The HFX concept borrowed some features used in other Ford vehicles, such as 4-wheel air suspension and electronic climate control. From there, some of the technologies showcased in the HFX had never before been seen in a minivan. This included run-flat tires, adjustable pedals, power-sliding side doors, electric power steering, ABS, traction control, seatbelt pre-tensioners, and movable grille shutters. On the rear, an LCD was installed to display 12 pre-programmed warning messages.
