The World Engine has five factories worldwide; two (GEMA) in Dundee, Michigan, United States, two in South Korea and one in Shiga, Japan. Production began in 2005 and will continue at least through 2012 with an annual capacity of approximately two million engines; each plant will be capable of producing 420,000. Twenty different automobile models from the three companies will use the engines. Each manufacturer configured their variants of the basic GEMA design differently based on their engineering needs and standards, so consumers may experience very different power, fuel efficiency, and "feel" from each manufacturer.
 
The Global Engine Manufacturing Alliance LLC, or GEMA, is a manufacturing arm of Global Engine Alliance LLC, which was a joint venture of Chrysler, Mitsubishi Motors, and Hyundai Motor Company for developing a line of shared engines. In September 2009, Chrysler bought out the shares of Mitsubishi and Hyundai after a 5-year run of allied research and development
