The Ford Aerostar was the first minivan introduced by Ford in the summer of 1985. The Aerostar was produced at Ford's St. Louis, Missouri assembly plant, which built the Ford Explorer, Mercury Mountaineer, and Lincoln Aviator. The Aerostar is often referred to as a "midivan" along with the RWD GM vans as a result of the size. The trucklike rear-wheel drive and towing capacity of the Chevrolet Astro/GMC Safari with car like user-friendliness of the Dodge Caravan/Plymouth Voyager made the Ford Aerostar a unique and successful model. The Ford Aerostar was stopped in 1997 and was replaced by the Windstar. Approximately 100,000 Aerostars were sold every year, outselling competition from GM. The Aerostar was Motor Trend magazine's Truck of the Year for 1990 and the first minivan with a 5-speed automatic transmission. .
The Ford Aerostar was built neither built on a car platform or a truck platform and was a rear wheel drive vehicle. The Ford Aerostar was the first American Ford to get an alphanumeric platform designation. The Aerostar was marketed as part of Ford's light-truck lineup. The Aerostar was available with either a 5-speed manual or the 4-speed A4LD automatic transmission. In 1996, the 4-speed 4R44E (3.0 Engine) and 4-speed automatic 4R55E (4.0 engine) transmissions were available.
