The '''Flat Rock Assembly Plant''' is a [[Ford Motor Company]] automobile assembly plant located at 1 International Drive in [[Flat Rock, Michigan]], within [[Metro Detroit]]. The facility covers 2,900,000 square feet (270,000 m²) of production space and employs approximately 3,510 hourly workers and 140 salaried workers. It currently manufactures the [[Ford Mustang]].
The plant was originally built by Ford as the '''Michigan Casting Center''' in 1972, but it closed in 1981. In 1987, [[Mazda]] took over the site and established its first U.S. manufacturing facility, '''Mazda Motor Manufacturing USA''' . In 1992, [[Ford Motor Company|Ford]] purchased a stake in the plant, and it was reorganized as the [[joint venture]] '''AutoAlliance International'''.<ref>{{cite web |title=AutoAlliance International, Inc. |url=https://www.hollingsworthllp.com/case-study/autoalliance-international-inc/ |access-date=August 28, 2025}}</ref> Mazda ended production there in 2012, after which the facility returned to full Ford ownership.<ref>{{cite news |last=Ohnsman |first=Alan |date=August 24, 2012 |title=Mazda Ends 20-Year U.S. Manufacturing Run |url=https://www.bloomberg.com/news/articles/2012-08-24/mazda-ends-20-year-u-s-manufacturing-run |access-date=August 28, 2025 |work=Bloomberg}}</ref>

=== AutoAlliance International (1992–2012) === On April 15, 1992, Ford repurchased a 50% stake in the facility, creating a joint venture with Mazda.

=== Flat Rock Assembly Plant (since 2012) === On September 10, 2012, Ford assumed full control of the facility, renaming it the Flat Rock Assembly Plant.
