Macomb County is ‘part’ of your vehicle

According to the Michigan Economic Development Corporation, Michigan has the highest percentage of auto production in the United States, with Detroit acting as the hub for all things automotive since the early 1900s. Since then, vehicle manufacturing has expanded throughout the metro area.

Macomb County lives 25 miles up the coast from the Motor City and acts as one major cog in the automotive machine here in Southeastern Michigan. While every car is not fully assembled here, our manufacturers help produce many of the parts that make up a vehicle, including some of the most important components, such as the engine, brakes and other electrical parts. In total, Macomb is home to 338 vehicle manufacturers that provide almost 22,000 jobs and $13 billion in revenue annually*.
