Trollhättan Assembly is an automobile factory in Trollhättan, Sweden. The factory opened in 1947 under the ownership of Saab AB, then passing to Saab Automobile. From 1989 to 2010, the factory was partially (1989–1999), then completely (2000–2010) owned by General Motors. In 2010, Saab was sold to Spyker Cars. The plant ended production in 2011 and restarted in 2013, after the National Electric Vehicle Sweden purchase of Saab Automobile. The Trollhättan complex, including the assembly, is now the sole site of all Saab engineering and manufacturing activities.
