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.

GEMA produces a single family of 4-cylinder engines with variable valve timing, marketed by Chrysler as the World Engine. The range starts with a 1.8 L unit which will principally find use throughout the world, and includes 2.0 L and 2.4 L variants which will find use in the United States. Turbocharged and supercharged versions may also be produced, as in Chrysler's similar Tritec engine.

Chrysler expects to use the GEMA family of engines in nine other models and projects that it will buy up to 840,000 GEMA engines annually.

The initial design of the engine block was handled by Hyundai. It features siamesed bores, meaning that there is no coolant flow between cylinders. The aluminum block has cast iron cylinder liners, and different liners can be fitted to alter the engine's bore.

The heads feature electro-hydraulic variable valve timing on both the intake and exhaust side. The system was based on that used by the recent Mercedes-Benz 24-valve V6 and is quite sophisticated and expensive for a low-end engine. A variable tumble control system creates air tumbles in the intake runners at low rpms for better mixture. Valves are directly actuated by solid Bucket tappets.
