HEMI® Engine Facts

Facts and Features

• Production of the 5.7-liter HEMI V-8 engine is at Chrysler Group's state-of-the-art Saltillo Engine Plant II in Saltillo, Mexico.
• In the newer Chrysler 300C, Dodge Magnum RT and the all-new 2005 Jeep® Grand Cherokee, the 5.7-liter HEMI is equipped with Chrysler Group's Multi-Displacement System (MDS), which turns off four of the cylinders when V-8 power is not needed, giving customers up to a 20 percent improvement in fuel economy.
• The 5.7-liter HEMI engine is an internally balanced pushrod, OHV 90-degree V-8.
• The cast iron block is a deep-skirt design with cross-bolted main bearing caps.
• The aluminum cylinder heads feature two valves per cylinder, hemispherical combustion chambers with dual spark plugs and coil-over-plug ignition.
• An Integrated Air Fuel Module (IAFM) incorporates the function of 26 individual components in the induction and fuel system, thereby reducing cost, weight and engine plant complexity.
• The 5.7-liter HEMI marks Chrysler Group's first application of an electronic throttle control in a rear-wheel-drive vehicle.
• A systematic approach to sealing, using premium elastomeric materials and state-of-the-art practices, helps ensure a leak-free, weep-free engine.
