5.9 is the rated 0-60 on the 2005 300C, so we were pleased when we got six flat on the almost four year old car. The 300C: The 300C comes with a 5.7 L Hemi V8. At full power, the 300C creates 340 hp and 390 lbs of torque. This engine runs on four cylinders when less power is needed to reduce fuel consumption. Even with this energy saving mode, the 300C runs at 15 mpg city, 23 mpg highway. All 300Cs use a 5-speed automatic transmission and standard 18 inch chrome-clad alloy wheels. Heritage Edition: The Heritage Edition 300C comes with the 5.7 L Hemi engine and many of the SRT-8’s exterior modification, added chrome, special tires on 18 inch wheels, and smartbeam headlights. Special SRT Packages: In 2007 the SRT Design group created a package for non-SRT 300C’s that includes performance suspension, SRT 20 inch polished aluminum wheels, a high speed engine controller with revised tuning for 5.7 L HEMI that brings the power to 350 HP, high flow air cleaner system, and performance exhaust. The SRT-8: The SRT-8 version of the 300 includes a 6.1 L Hemi V8 which produces 425 hp. This engine produces 0-60 mph times of 5.1 seconds. The SRT-8 includes leather SRT-8 performance seats, 20 inch polished aluminum wheels, Brembo brakes, and rear lip spoiler.
