GM Korea has taken responsibility for future development of GM's GSV (Global Small Vehicle) architecture. This architecture will eventually be used for all small vehicles from GM, as a true global small car platform. While the original Gamma was developed by Opel, the Gamma II platform is under the leadership of GM Korea (formally GM Daewoo).
The vehicles will be assembled at factories in the United States, Indonesia, Ecuador, Brazil, Germany, Colombia, Spain, India, South Korea, Mexico, Thailand, Venezuela, Uzbekistan, Vietnam, China and Russia.
