The Stellantis Sochaux Plant is one of the principal car plants in France - in 2007 approximately 326,000 cars were produced there, and as of May 2011 the staff numbered 11,972 permanent workers, approximately 2,000 temporary workers, as well as over 800 employees from other companies working at the Sochaux plant. The plant was created by Peugeot in 1912, initially as a truck factory, but by the 1930s it had become the company's principal car manufacturing plant, and the main production site for all principal Peugeot models from then until 1972, when the company established a second major French car assembly plant in Mulhouse.
In December 2010 the plant produced its 20 millionth car and celebrated by donating the car in question, a Peugeot 5008, to the Haiti Protestant Federation (Fédération protestante d'Haïti), backing the charity's orphan support work in the wake of a major earthquake.The plant is located in Sochaux in the department Doubs, at the eastern extremity of the Franche-Comté.
During the first decade of the twenty-first century the plant's principal product was the Peugeot 307, while the company's smaller cars were produced at the Mulhouse plant, less than two hours by road to the east, and the larger 406s and 407s were produced at the Rennes plant in north-west France. The low volume Peugeot 607 was also produced at Sochaux for most of its life.
Currently, Sochaux production is focused on Peugeot's 3008 and 5008 models. In addition, a new era dawned in 2011 when, for the first time, a Citroën branded car, the Citroën DS5, joined the Peugeots on the Sochaux production lines.
