New for the 2012 Charger SRT8 is the 470 horsepower 6.4-litre HEMI® V8 that features 45 more horsepower and 50 more lb.-ft. of torque across a significantly wider rpm range, new Exhaust system technology for improved fuel efficiency, along with new paddle shift technology and adaptive damping suspension for optimal driver control.
Performance numbers for the 2012 Dodge Charger SRT8 include 0-96 km/h (0-60 mph) acceleration in the high 4-second range; quarter mile in the high 12-second range; 0-160-0 km/h (0-100-0 mph) in less than 16 seconds; top speed of 282 km/h (175 mph) and stopping power from 96-0 km/h (60-0 mph) in 37metres (120 feet).
Under the hood, the new 6.4- litre HEMI® V8 delivers more horsepower and torque than the 6.1-litre HEMI V8 it replaces -- up 11 per cent to 470 horsepower (351 kW) and up 12 per cent to 470 (637 N•m) lb.-ft. of torque.
► 2012 Dodge Challenger SRT8 392 on the Track
The 392-cubic inch (6.4-liter) HEMI® V-8 delivers 470 horsepower (351 kW) and 470
(637 N•m) lb.-ft. of torque. The torque band is extremely flat allowing
for strong standing starts and improved straight-line performance
throughout the rpm range. An advanced active intake manifold along with
high-lift cam with phasing provides maximum low-end torque and high-end
power while still delivering up to 23 miles per gallon on the highway with
the standard manual transmission. Performance-tuned engine mounts improve
idle stability and ride control at all speeds.
Standard Fuel Saver Technology (four cylinder mode) in automatic
transmission equipped models allows the engine to operate economically on
four cylinders or use the power of all eight cylinders when needed. The EPA
fuel economy miles per gallon (mpg) (City/Hwy) ratings for the 2012 Dodge
Challenger SRT8 392 are 14/22 for automatic transmission models and 14/23
for manual-transmission models.
A look under the hood reveals unique valve covers with painted silver ribs
and the "392 HEMI" logo, which gives the engine a unique, clean and
The 2012 Dodge Challenger SRT8 392 features a standard Tremec TR-6060
six-speed manual transmission and a dual-disc high performance clutch -- a
proven performer that was first offered on the 2008 Dodge Viper SRT10®.
The optional five-speed automatic transmission features new, standard
steering wheel mounted paddle shifters that join the center console mounted
Auto Stick, allowing for a choice of spirited shifting on both the road and
the race track. Both methods give the driver the ability to manually select
specific gears on the transmission.
In "Drive," the transmission controller will automatically shift the
vehicle. The aggressiveness of the shifting is defined by the mode chosen -
either "Normal" or "Sport." Fully adaptive electronic control of all
shifting makes the powertrain more responsive while minimizing harshness.
In "Manual," the shift method is defined by the driver choosing to use
either paddle shift or Auto Stick. The "Sport" mode adds a hold function to
the calibration in all gears, allowing the driver full control of the

The Street and Racing Technology (SRT) performance engineering team builds
upon the all-new 2011 Chrysler 300 sedan already executed for a world-class

The return of the 300 SRT8 to the Chrysler lineup in 2012 evokes a strong
comparison to the original high-performance production car of its time --
the 1955 Chrysler 300. Known for simple, strong lines, excellent
engineering, high levels of luxury and outstanding performance with the
first modern American V-8 engine to produce 300 horsepower, the first
Chrysler 300 (C-300) was styled by Virgil Exner, who radically redesigned
the entire Chrysler line and created what they called "The Forward Look" in
1955. Without much chrome on the sides, his designs were simple, but
strong. Exner is credited with creating the illusion of fast, forward
Under the hood of the 2012 Chrysler 300 SRT8, the new 6.4-liter HEMI® V-8

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.
