Every car built in America carries the hard work, skill, and dreams of thousands of Michiganders. Michigan doesn’t just assemble vehicles — this state forms the backbone of the entire U.S. automotive industry. Detroit may be called Motor City, but the state’s real strength spreads across Auburn Hills, Warren, Novi, Northville, Grand Rapids, Holland, and many more cities where critical components are made every single day.
Inside Michigan’s factories, workers produce seats, doors, sensors, batteries, drivetrains, safety systems, and countless engineered parts. Modern cars would not exist without the innovation and supply chain rooted in this state.
