5.7-liter HEMI® V8 engine with Multi-Displacement System (MDS), 340 horsepower at 5,000 rpm, and 390 lb-ft of torque, standard on 300C—the most horsepower and torque in its class.* The MDS system allows the engine to operate on four cylinders when power demands are minimal, increasing fuel efficiency by up to 20 percent. This provides the power of a V8 with the economy of a large V6. (EPA estimated mpg: 17 city/ 25 highway)
3.5-liter high-output V6 single overhead camshaft (SOHC) engine with 250 horsepower at 6,400 rpm and 250 lb-ft of torque, standard on 300 Touring and 300 Limited. (EPA estimated mpg: 18 city/ 28 highway)
