Here's a breakdown of the new Hemi's specs:
• The 5.7-liter engine is an internally balanced pushrod (OHV) 90-degree V-8. The cast-iron block is a deep skirt with cross-bolted main bearing caps.
• Fuel economy has been improved, but not at the expense of Hemi performance. Multi-Displacement System (MDS) is technology that deactivates four cylinders when the V-8 is not needed. This increases fuel economy by up to 20 percent.
• The aluminum cylinder head features a two-valve-per-cylinder, hemispherical combustion chamber with dual spark plugs and a 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 engine marks Chrysler Group's first application of an electronic throttle control system in a rear-wheel-drive vehicle. The system uses a DC motor with reduction gears to open and close the throttle, for optimal control of the airflow into the engine.
• The power plant's simple and efficient design means servicing and repairs are easier and less costly.
The new Hemi is featured in the following vehicles: Dodge Ram, Magnum RT and Durango, Chrysler 300C and Jeep® Grand Cherokee. Later this year, the Hemi will be available in the all-new Dodge Charger and Jeep Commander.
