Gamma is General Motors' global subcompact front-wheel drive automobile platform, first used in the 2000 Opel Corsa C.

Gamma / GM4300[edit]

The first version of the platform was issued in autumn 2000 with the introduction of Opel Corsa C and was a development of the earlier GM4200 platform used in previous Corsa models, developed by Opel in Germany. The wheelbase was enlarged to 2,491 mm (98.1 in) from 2,465 mm (97.0 in) on the GM4200.

GM Korea has taken responsibility for future development of GM's GSV (Global Small Vehicle) architecture.[1][2] This architecture will eventually be used for all small vehicles from GM, as a true global small car platform.[3] While the original Gamma was developed by Opel, the Gamma II platform is under the leadership of GM Korea (formally GM Daewoo).[4]

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.
