On March 17, 1997, Ford announced the discontinuation of the Ford Aerostar, alongside the Ford Aspire, Ford Probe, and Ford Thunderbird/Mercury Cougar. The final vehicle rolled off the St. Louis assembly line on August 22, 1997; a total of 2,029,577 were produced over 12 years. Alongside the production of the Ford Windstar, a primary factor leading to the cancellation of the Ford Aerostar was an impending requirement for the addition of dual airbags, which would have required a complete (and costly) redesign of the front dashboard and front crash structure.
