SPRING HILL, TN—A decade after announcing plans to build a new assembly plant in Chattanooga, TN, French automotive supplier Faurecia is continuing to expand in Tennessee with plans to invest another $18 million and add another 171 jobs at the company’s assembly plant in Spring Hill, TN.

One of the top 10 global automotive suppliers, Faurecia will add nearly 100,000 square feet to its Spring Hill facility, which is located near GM’s assembly plant, to boost production of door panel assemblies. The expansion will double Faurecia’s investment in Spring Hill and more than double employment there.

The Faurecia expansion is among nearly $10 billion of new automotive production investments planned or underway in Tennessee, which has already emerged as the biggest car-producing state in the Southeast.
