Hemi Definition from Mopar Site
The new Hemi produces 345 horsepower (5,600 rpm) and 375 lb-ft of torque (4,400 rpm) from 5.7 liters (345 cid*) when used in the Dodge Ram - one horsepower per cubic inch.
In addition to Ram, Durango, and Grand Cherokee duty, the Chrysler Hemi is used in the LX large cars, in front of a Mercedes five-speed automatic which early reports suggest is much more troublesome than the Hemi itself. The Hemi is smaller, faster, and more economical (we hear also cheaper to build) than the 360 it is replacing. What's more, a 6.1 liter version is being developed for even more power, to replace the current V-10.
The Hemi features cylinder deactivation in the 300C and Magnum R/T; the "Multi Displacement System" (MDS) turns off the fuel consumption in four cylinders when V-8 power is not needed. This provides a world class combination of performance and fuel economy, without the driver noticing any difference.
The Hemi's first vehicle was the 2500 and 3500 Rams, where it is the base engine. It moved next into the Ram 1500 (calendar year 2002), then to the Grand Cherokee, LX cars, Durango, and Dakota.
Oddly, the new Hemi appears to use 5W20 motor oil - a specification which is expected to be widely adopted, but which is still not widely available.
