Press Release) The new 6.1-liter SRT version of the
legendary HEMI engine was inspired by the original family of HEMIs –
particularly the namesake hemispherical combustion chambers that
provide power and efficiency and select visual cues, including the
classic orange-painted cylinder block and black valve covers.
The new engine also matches the legendary “Street HEMI” of the 1960s
and 1970s with its 425-horsepower rating. But it does so with less
displacement. The 6.1-liter HEMI’s 69.8 horsepower-per-liter rating
exceeds that of the Street HEMI.
Today’s SRT HEMI is subject to many requirements that older engines
didn’t have to meet – requirements for emissions and fuel
With the Chrysler Group’s clean and efficient all-new 5.7-liter HEMI
as a starting point, SRT powertrain engineers developed 85 more
horsepower by adding more cubic inches, increasing the compression
ratio, redesigning the cylinder head, intake and exhaust systems for
increased flow, and increasing engine speed.
For more displacement, SRT engineers bored out the diameter of the
cylinders in the HEMI by 3.5 millimeters each in order to increase
the total displacement to 6.1 liters from 5.7 liters.
Compression ratio was also increased to 10.3:1 from 9.6:1,
increasing engine efficiency and power.
Engine breathing was increased with new higher-flow cylinder heads,
a specially designed intake manifold, and exhaust headers with
individual tubes encased in a stainless steel shell, all unique to
the 6.1-liter HEMI engine. Larger-diameter valves and reshaped ports
in the heads allow for maximized air flow. The intake manifold was
designed with larger-diameter and shorter runners for higher-speed
tuning. Exhaust is routed through a large-diameter (2.75-inch vs.
2.5-inch) exhaust system with 3.5-inch chrome tips.
To further increase horsepower, performance-oriented camshaft
profiles were developed to allow more air in and out of the
cylinders, as well as manage a higher engine speed. SRT engineers
increased the HEMI’s peak power output engine speed nearly 20
percent, to 6,000 revolutions per minute (rpm) from 5,000 rpm.
Intake and exhaust valve stems are hollow, and the exhaust valve
stems are filled with sodium to help dissipate heat more
The high-performance SRT 6.1-liter HEMI is strengthened with
redesigned components, including a reinforced engine block, forged
steel crankshaft, high-strength powdered-metal connecting rods,
floating-pin pistons (cooled by oil squirters), and an oil pan
modified to manage oil return to the pan sump at high engine speeds.
Power for the SRT 6.1-liter HEMI is channeled through an A580
five-speed automatic transmission with specially calibrated
driver-selectable AutoStick®, which offers fully automatic or manual
shifting selection. A heavy-duty four-flange prop shaft sends the
torque from the transmission to an upgraded differential and axles.
2006 Dodge Magnum SRT8 Ride and
The all-new 2006 Dodge
Magnum SRT8 is set up for outstanding ride and handling across a
Chassis setup for the Dodge Magnum SRT8 is aimed at all-around
performance with SRT-tuned dampers, specially tailored spring rates
and suspension bushings, and large-diameter anti-sway bars. The ride
height of the Magnum SRT8 is one-half inch lower than the Dodge
Magnum, while the Electronic Stability Program (ESP) has been
specially tuned for the 2006 Dodge Magnum SRT8’s performance
The all-new 2006 Dodge Magnum SRT8 will meet the road with a new
wheel and tire assembly consisting of unique 20-inch forged aluminum
wheels shod with high-performance Goodyear F1 three-season tires
with asymmetrical tread (four-season tires are an available option).
Tire dimensions are a formidable 245/45/20 in the front, and
255/45/20 in the rear.
2006 Dodge Magnum SRT8 Braking
One of the most
significant dimensions of well-balanced performance is the ability
to slow and stop as safely and predictably as possible. The braking
system of the 2006 Dodge Magnum SRT8 was designed to provide
benchmark braking performance, setting a new standard for cars in
All four wheels feature performance brake calipers developed by
Brembo and finished in Dodge SRT red. Each is equipped with four
pistons for even clamping performance. The Dodge Magnum SRT8 has 360
x 32mm vented rotors up front, with 350 x 26mm vented rotors in the
2006 Dodge Magnum SRT8 Exterior
Dodge Magnum is striking
with its raised beltline and roofline pulled down tautly around the
windows. SRT stylists made functional improvements that resonate
with the Dodge brand’s character and contribute to performance.
For example, an all-new front fascia helps increase cooling through
integrated ducts that help direct air to cool the brakes. A front
air dam reduces lift, while in the rear, there is an all-new fascia
with an integrated wake modifier and aggressive cutouts to
accommodate the dual 3.5-inch exhaust tips.
Dodge Magnum SRT8 styling is also unique with a body-color grille
insert with chrome trim, satin-finish front and rear bumper inserts,
body-color mirrors and door handles, and unique SRT badging.
Three exterior colors are available: Bright Silver, Brilliant Black
and Inferno Red Crystal Pearlcoat.
2006 Dodge Magnum SRT8 Interior
Inside, the 2006 Dodge
Magnum SRT8 features power-adjustable, deeply sculpted and highly
bolstered sport seats in the front complete with performance suede
inserts to hold the occupants during maneuvering. All seats have
contrasting red stitching.
Other amenities include “carbon fiber” leather trim for better grip
on the steering wheel, and special carbon fiber finishing on the
Full instrumentation, including a 180-mph (300 kph) speedometer,
tachometer and temperature gauges, befits the performance-oriented
character of the 2006 Dodge Magnum SRT8’s interior.
Standard features of the 2006 Dodge Magnum SRT8 include AM/FM radio
with six-disc CD changer, steering wheel-mounted audio controls,
power adjustable pedal cluster and rear cargo net.
Options available on the 2006 Dodge Magnum SRT8 include power
sunroof, heated seats, supplemental side air bags, and the Trailer
Tow Group which offers load leveling and height control.
Also available are SIRIUS® Satellite Radio and a UConnect™
hands-free communications system with Bluetooth™ technology. This
system recognizes up to seven different Bluetooth-equipped cellular
phones and responds to voice commands, utilizing a microphone in the
rear-view mirror and the stereo system’s speakers for hands-free

2006 Dodge Magnum SRT8 Safety and
Windows: An advanced sensing system automatically reverses
window direction when it senses resistance
Air Bag System: Inflates with a force appropriate to the
severity of impact. Includes occupant classification system
System: Equipped with electronic sensors that help prevent wheel
lockup. The optional ABS system offers improved steering control
under extreme braking and/or slippery conditions
Crush zones and stiffeners engineered into the vehicle body help
absorb energy, while preserving the integrity of the vehicle
compartment. These reinforcements provide additional protection
in an offset-type impact
Child Seat Anchor
System: The Lower Anchors and Tethers for CHildren (LATCH)
system eases installation of compatible aftermarket child seats
Retractors (CFR): Front seat belts include a mechanical device
that distributes the force of a seat belt according to the load
or force exerted on it. CFRs are engineered to force-limit the
belt system, and gradually release the seat belt webbing in a
controlled manner during a crash
Program (ESP): This available feature aids the driver in
maintaining vehicle directional stability, providing oversteer
and understeer control to maintain vehicle behavior on road
Steering Column: Manual-adjust steering column includes two
hydroformed coaxial tubes that move relative to each other,
which allows the column to move forward and provide more energy
absorption during a crash. The power-adjust steering column uses
a calibrated bending element that deforms during column stroke
for optimal energy management
Classification System (OCS): The OCS measures conditions for
activation or deactivation of the passenger side front air bag
based upon the weight of the occupant
During a collision, impact sensors initiate front seat belt
pretensioners to immediately remove slack from seat belts, which
reduces forward movement of the occupant’s head and torso
Side-curtain Air Bags: The side-curtain extends protection to
front and rear outboard passengers
