2012 Chrysler 300C SRT8 HEMI Engine:
Awe-inspiring powertrain -Under the hood of the 2012 Chrysler 300 SRT8, the new 6.4-liter HEMI V-8 makes its debut in the Chrysler brand product lineup delivering an estimated 465 horsepower and 465 lb.-ft. of torque, up 40 horsepower and 45 lb.-ft. over the 6.1-liter HEMI V-8 it replaces.
The improved torque output - including an additional 80 lb.-ft. at 2,900 rpm - allows for inspired standing starts and improved straight-line performance while new, performance-tuned motor mounts improve idle stability and ride control at any speed. An active intake manifold and high-lift camshaft with cam phasing provides maximum low-end torque while optimizing high-end power.
Even with the elevated power numbers, an estimated 25-percent fuel economy increase on the highway is achieved by use of a new for 2012 active valve exhaust system that allows the standard Fuel Saver technology (four-cylinder mode) to engage over a wider rpm range. The new active exhaust system also allows for straight-through mid and rear mufflers for a throaty exhaust note under engine load.
Specific fuel economy numbers will be announced closer to the vehicle introduction.
Standard steering wheel-mounted paddle shifters join the standard Auto Stick on the floor console. Both are mated to the proven five-speed automatic transmission, allowing a choice of spirited shifting on the road and the race track.
Both methods give the driver the ability to manually shift the transmission. The transmission controller calibration in "Auto" mode prevents situations that might over rev the engine; while in "Sport" mode, it allows the driver full control of the shifting schedule. Fully adaptive electronic control of all shifting makes the powertrain more responsive while minimizing harshness.
