GM GEM platform

Global Emerging Markets, better known in acronym form as GEM, is the name of an automotive platform in use by General Motors for various vehicles sold in markets of the developing world, where many GM vehicles designed for the United States and wealthier parts of China are too expensive for most consumers.

Development of GEM in particular was largely done by GM's joint venture SAIC-GM in China. It was developed by the GM-SAIC joint venture Pan Asia Technical Automotive Center (PATAC). Creating the platform reportedly came at a cost of approximately 5 billion dollars to GM, much of the funds for which were accumulated by exiting several unprofitable markets in Europe and Africa in 2017.
