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. Source Of
