WardsAuto.com is reporting that Ford's next-generation Fusion will be built at the AutoAlliance International plant in Flat Rock, MI, 25 miles southwest of downtown Detroit. The news comes out of the tentative labor agreement with the UAW that was announced today. Ford has said it will add 12,000 hourly manufacturing jobs in the U.S. by 2015, including some jobs that are returning to the U.S. from Mexico, China, and Japan.

AutoAlliance is a joint-venture plant owned with Mazda, where Ford builds the Mustang alongside the Mazda6. The current Fusion is assembled at Ford's Hermosillo Stamping & Assembly plant in Mexico, though it shares a platform with the Mazda sedan. The move to Flat Rock all but insures that the forthcoming Fusion will continue to maintain that close connection. Speculation has the new Fusion dropping at the 2012 Detroit Auto Show.
