The 5.7 liter, 345 cid HEMI V8 is the first HEMI designed engine used in 30 years. Making its debut in 2002 in the Dodge Ram 2500 and 3500 models. Since then it has been used in several RWD Chryslers, Dodges and Jeeps such as the 300C, Charger, Challenger, Magnum, Grand Cherokee and Commander. The Hemi is smaller, faster, and more economical than the 360 it replaced. It also features cylinder deactivation, which stops sending fuel to four of the cylinders when V8 power isn’t needed. The new Hemi appears to use 5W20 motor oil - a specification that is expected to be widely adopted, but which is still not widely available. Chrysler engineer Tom Hoover, who is associated with the 426 Hemi, told Hot Rod that he had discussed the Elephant Engine's design with new-Hemi engineers. At least two of his suggestions, raising the camshaft (which let them use shorter pushrods, reducing valve train inertia, and have simpler exhaust rocker arms), using twin spark plugs for cleaner running, and adding squish area (to make light load/low speed efficiency better and reduce emissions) were immediately adopted. Hoover emphasized that what they had learned from the original Hemi was used in the new version.
