The 300C gets Chrysler's powerful 5.7L "Hemi" V8 engine that makes 360 horsepower and 389 lb-feet of torque. The engine's flex-fuel capable and features a multi-displacement system, which turns off cylinders while cruising to save fuel. The Chrysler Hemi engines, known by the trademark Hemi or HEMI, are a series of American V8 gasoline engines built by Chrysler with overhead valve hemispherical combustion chambers. Three different types of Hemi engines have been built by Chrysler for automobiles: the first (known as the Chrysler FirePower engine) from 1951 to 1958,[1] the second from 1964 to 1971, and the third beginning in 2003. Although Chrysler is most identified with the use of "Hemi" as a marketing term, many other auto manufacturers have incorporated similar designs. The engine block and cylinder heads were cast and manufactured at Indianapolis Foundry.
