The 5.7-liter HEMI® Magnum V-8

Auburn Hills, Mich. -- While completely re-engineered from the legendary 426 HEMI V-8 that powered Chrysler muscle cars of the 1960s, two features earn the new 5.7-liter HEMI power plant its HEMI name.

The hemispherically shaped combustion chamber designed to accommodate large valves and put the spark plugs close to the center of the combustion chamber The cross-flow valve arrangement that is perpendicular to the crankshaft Centerline

Facts and Features

The 5.7-liter HEMI® Magnum V-8 engine is an internally balanced pushrod (OHV) 90-degree V-8. The cast iron block is a deep skirt and cross-bolted design with cylinder bore spacing the same as the engine it replaces. The aluminum cylinder features a two-valve per-cylinder, hemispherical combustion chamber with dual spark plugs and a coil over plug ignition for best-in-class airflow and power. At an impressive 345 hp and 375 lb.-ft of torque, the 5.7-liter HEMI cranks out 41 percent more power and 12 percent greater torque than the 5.9-liter Magnum V-8 it replaces. And the power plant is 56 pounds lighter than its predecessor. 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 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. A combination of the 5.7-liter HEMI and the new 545RFE five-speed automatic transmission will improve fuel efficiency for the heavy-duty pickup by 8-10 percent over the 5.9-liter V-8.A systematic approach to sealing, using premium elastomeric materials and state-of-the-art practices, helps ensure a leak-free, weep-free engine.

The power plant’s simple and efficient design means servicing and repairs are easier and less costly.
