The GEMA alliance has ended this month. GEMA stands for Global Engine Manufacturing Alliance, and was a joint venture between Mitsubishi, Chrysler and Hyundai-Kia to develop a family of 4-cylinder engines.
There are currently three different sizes available – 1.8 litre, 2.0 litre and 2.4 litre. In Malaysia, there are a few cars that use engines derived from the GEMA project – the 2.0 litre motors in the Lancer and Lancer Evolution X, and the 2.0 litre motors in the Hyundai Sonata, Kia Optima and Naza Rondo.
Chrysler says it intends to replace its GEMA engines with new small engine technology it will gain access to from its new Italian partner Fiat. But interestingly, despite Chrysler stating an intention to replace its GEMA products with Fiat products, Chrysler is the one who has ended up with full ownership of the GEMA plant. Mitsubishi and Hyundai have just sold their stakes to Chrysler. It is likely that the plant will be converted to a plant making Fiat engines in the future.
Technology bought to GEMA by an individual company will remain the intellectual property of that company, so Hyundai and Mitsubishi will likely be able to continue using their Theta/Theta II and 4B series of engines respectively.
