2005 Chrysler 300C HEMI Maisto 1:18

The top-of-the-line 300C version uses a 5.7 L (345 cu in) Hemi V8. Using the Multidisplacement System (MDS), this engine can run on four cylinders when less power is needed in order to reduce total fuel consumption. The USEPA-rated fuel consumption of the 300C is: 15 miles per US gallon (16 L/100 km; 18 mpg‑imp) city, and 23 miles per US gallon (10 L/100 km; 28 mpg‑imp) highway. When all eight cylinders are needed, the 300C can produce 340 hp (254 kW) and 390 lb⋅ft (529 N⋅m) of torque. It uses a five-speed automatic transmission and comes standard with 18-inch chrome-clad alloy wheels, Chrysler's MyGIG Infotainment System in 2008 and SIRIUS Satellite Radio and Backseat Television in 2008. The HEMI cylinder heads necessitate the use of a double rocker arm shaft configuration, with a cam-in-block, overhead valve (OHV) pushrod design. There are two spark plugs per cylinder to promote efficient fuel/air mixture burn and thereby reduce emissions. In 2009–2010 power output was increased to 360 hp (268 kW; 365 PS).
