Saab-Valmet was established in 1968 as a joint venture of Finnish Valmet and Swedish Saab-Scania. The automotive plant was placed in Uusikaupunki, Finland and assembled only Saabs for the first eleven years. Between 1979 and 1985, Valmet also assembled Talbots; a total of 31,978 such cars were built in Finland. Valmet were only really interested in building the compact Simca-Talbot Horizon, but the French company required Valmet to also assemble the larger (and slow selling) 1307 before they would license the Horizon. Unlike Saabs, the Simca-Talbots were only meant for local consumption, although a clause in the contract allowed for the possibility of exports if parts made by the thirty local suppliers began to be exported to Talbot's main plants. Domestic parts content increased to thirty percent within a half year of manufacture commencing.
In 1992 Valmet became the sole owner, and the company was renamed Valmet Automotive in 1995. From 1999 to 2010, the sole owner was Metso, after which both Finnish Industry Investment (Tesi) and Pontos Investments bought 34% of the company's shares. On November 4, 2010, Valmet Automotive bought Karmann’s roof-component sections in Osnabrück, Germany, and Żary, Poland. In January 2017, CATL became a 23.08% minority stakeholder in the company, the other shareholders being Pontos and Tesi (Finnish Industry Investment).
