and Assembly. The vehicle was retained on display at the Spartanburg Plant to commemorate the milestone. The $2.2 billion plant, which employs 23,000 (BMW and contract), is part of the company’s global five-plant production network. The automaker announced in 2014 an additional $1 billion investment in the facility that will make Spartanburg, South Carolina, BMW's largest US factory, with an annual capacity of 480,000 units when including the X7. There were 411,171 vehicles produced in 2016, of which 70% were exported to 140 countries. The plant is the largest BMW plant in the world in terms of vehicle production volume. Another record was set in 2018, around 70% of production was exported to 125 markets. The biggest export market was China, accounting for one-third of all export. That same year, BMW ceased exporting the X3 to China. A nearby dry inland port, from the port of Charleston, handles many of the plant's needs for cargo and finished vehicles. In 2015 BMW Spartanburg sent 250,000 new cars by rail from to the Charleston port. Some air freight is also used.
