Press Release) High-caliber Performance: with over 300 Horsepower,
All-new Dodge Caliber SRT4 Poised to Dominate Sport-compact Market
• Tyre-smoking 223 kW (303 hp DIN) “hot hatch” with 352 Nm (260
lb.-ft.) of torque
• 0-100 km/h acceleration in approximately six seconds
• All-round performance of a true “tuner car” right from the
manufacturer with full warranty
• Benchmark performance at the best price
Chrysler Group’s Street and Racing Technology (SRT) group takes its
ultimate-performance reputation to new heights with the introduction
of the all-new 223 kW (303 hp DIN) Dodge Caliber SRT4.
“The all-new Dodge Caliber SRT4 achieves the SRT mission of offering
benchmark performance for the best price,” said George Murphy,
Senior Vice President – Global Marketing, Chrysler Group. “With over
300 horsepower under the hood, the Dodge Caliber SRT4 will dominate
the sport-compact market.”
Thanks to its true “tuner performance” right out of the box and a
great price, enthusiasts in the USA immediately took to the original
Neon-based Dodge SRT4, which was introduced in 2003 at the Los
Angeles Auto Show. In the 2003-2005 model years, more than 25,000
Dodge SRT4s were sold.
“We couldn’t wait to infuse Dodge Caliber with the SRT formula and
bring it to a European and international audience,” said Murphy.
“The Dodge Caliber SRT4 delivers a strong dose of all-round
performance while delivering more than 28 miles per gallon on the
highway in U.S. tests. Our new SRT pocket rocket is going to be a
hoot to drive.”
For Europe and other markets outside North America, the Dodge
Caliber SRT4 will be available beginning in late 2007.
Street and Racing Technology
Since its inception in 2002, SRT has introduced 12
extreme-performance vehicles, including the Viper-powered Dodge Ram
SRT10 regular cab and Quad Cab™, Chrysler Crossfire SRT6 Coupe and
Roadster, Chrysler 300C SRT8 saloon and Touring, Dodge Magnum SRT8,
Dodge Charger SRT8, Dodge Viper SRT10 Coupe and Roadster and Jeep®
Grand Cherokee SRT8.
Every SRT vehicle showcases five key aspects:
• Exterior styling that resonates with the brand image
• Race-inspired interiors
• World-class ride and handling characteristics across a dynamic
• Benchmark braking
• Standout powertrains
Functional, Performance-oriented Exterior Design
Because there is only one chance to make a first impression, the
all-new Dodge Caliber SRT4 makes the most of it with muscular
“From the very first sketches of the all-new Dodge Caliber SRT4, we
wanted an aggressive, SRT-signature look,” said Trevor Creed, Senior
Vice President – Design. “For example, because the intercooler is
positioned so high behind the front grille, we moved the fascia
slightly forward and extended the walls of the grille. The result is
a much more aggressive look than the standard Dodge Caliber.”
An all-new front fascia below the signature Dodge crosshair grille
incorporates functional performance features including ducts that
direct air to cool the brakes and a wide centre inlet that provides
air flow to the radiator. Fog lamps are also set into the fascia,
alongside the brake ducts. The Dodge Caliber SRT4’s bonnet
incorporates a functional scoop that brings cooling air into the
engine compartment and a pair of extractors that exhaust hot air.
“Exterior design that works as well as it looks is a requirement for
all SRT vehicles,” said Creed. “The hood design had to include the
functionality of bringing cool air in and getting hot air out.”
The lowest portion of the Dodge Caliber SRT4’s fascia, which acts as
an air dam to direct air around the front of the vehicle, wraps
around to visually integrate with the radiussed wheel wells and
lower side-sill mouldings.
The rear fascia continues the muscular, functional character of SRT
vehicles, with lower vertical strakes that direct underbody air flow
out the back of the vehicle, contributing to more stability at high
speed. A single, 8.9cm (3.5 in.) exhaust tail pipe exits from the
right side of the fascia.
Aerodynamic efficiency is also aided by an integrated spoiler above
the rear tailgate glass, which incorporates the centre high-mounted
stop light (CHMSL). This spoiler, which is nearly 60 per cent larger
than that on the standard Dodge Caliber, is tuned for smoother air
flow and to generate downforce while maximising the rear view.
Four exterior colours will be available on the all-new Dodge Caliber
SRT4: Brilliant Black, Sunburst Orange, Bright Silver and Inferno
Race-inspired Interior Appointments
In the “business office” of the five-door Dodge Caliber SRT4, a new
interpretation of traditional SRT themes is carried out.
“The Dodge Caliber interior is unique with sophisticated and
contemporary appointments,” said Creed. “When we enhanced it with
SRT cues, we followed design themes that had been successful with
the previous Dodge SRT4, including the graphic design of the
instruments, separate boost gauge, and silver finish on the centre
stack and interior trim.
“Overall, our strategy was to infuse the interior with
performance-oriented enhancements to complement the Dodge Caliber
SRT4’s aggressive exterior,” Creed added.
Unique SRT touches include sport seating with pronounced bolstering
and performance fabric inserts to hold occupants during spirited
driving, and a leather-wrapped steering wheel with a “carbon fibre”
pattern on the upper portion. The seats, steering wheel and leather
gear-shift boot feature contrasting stitching. Also unique to the
Dodge Caliber SRT4 is an “alloy silver” finish on the instrument
panel and shift bezel, and bright aluminium pedal pads that feature
rubber studs for enhanced grip.
The centre-stack-mounted gear shift lever includes a lift ring to
engage reverse, unique to the Dodge Caliber SRT4, as well as a
leather-finished shift knob.
The instrument panel features three gauge “tunnels” outfitted with
performance-oriented instrumentation, including a tachometer, 260
km/h (160 mph) speedometer, and water-temperature and fuel gauges. A
turbocharger boost gauge is located on the left side of the
instrument panel (and on the right side of the instrument panel for
For the enjoyment of audiophiles, the Dodge Caliber SRT4 is equipped
with a standard AM-FM radio with a multi-disc CD changer. An
available SRT/Kicker high-performance audio system boasts up to 13
speakers in seven locations, powered by a 322-watt amplifier and
The interior upholstery and trim of the Dodge Caliber SRT4 is
offered in Dark/Light Slate Gray.
World-class Ride and Handling
Another hallmark of SRT’s balanced approach to performance is ride
and handling characteristics that make a smooth transition from
street to track.
The Dodge Caliber SRT4 rides on SRT-unique 19-inch cast aluminium
wheels with 225/45R19 W-rated Goodyear tyres. Wheel hubs and
bearings on all four corners are adapted from Chrysler Group
mid-size cars for strength.
Upgrades to the standard Dodge Caliber’s MacPherson strut front
suspension include new suspension knuckles and tuned dampers with
revised spring rates. Unique front and rear anti-roll bars keep body
roll to a minimum during hard cornering.
The standard-fit Electronic Stability Programme (ESP) is uniquely
calibrated for the Dodge Caliber SRT4 to provide excellent
directional stability in all driving modes. In addition, stability
is enhanced with a ride height 1.3cm (0.5 in.) lower than the
standard Dodge Caliber.
Rack-and-pinion power steering is tuned to produce easier low-speed
manoeuvring, without compromising performance at speed. The overall
steering ratio is 16.6:1.
Benchmark braking is another ingredient in SRT’s performance recipe.
Although it is a C-segment car, the Dodge Caliber SRT4 benefits from
braking-system components designed for much larger, heavier cars.
For example, front brake callipers were sourced from a premium brake
system developed for the Chrysler 300C, Dodge Magnum and Dodge
Charger, while rear callipers were sourced from Chrysler Group
mid-size cars. However, all are painted in signature Dodge SRT red.
Vented brake rotors are 340x28mm in front and 302x10mm in the rear.
The anti-lock braking system (ABS) was uniquely calibrated for the
Dodge Caliber SRT4’s performance to maintain directional stability
without wheel lockup.
The five-door hot-hatch Dodge Caliber SRT4 is capable of a 0-100
km/h time in approximately six seconds. How is that possible?
The latest SRT model gets its motivation from an all-new World
Engine produced at the Global Engine Manufacturing Alliance (GEMA)
facility in Dundee, Mich. The World Engine is a family of fuel- and
emissions-efficient aluminium four-cylinder petrol engines
co-developed by DaimlerChrysler’s Chrysler Group, Hyundai Motor
Company and Mitsubishi Motors Corporation.
“The all-new 2.4-litre turbocharged World Engine delivers a level of
power you’d expect from a V-8,” said Pete Gladysz, Senior Manager –
Powertrain, SRT. “With the engine in the all-new Dodge Caliber SRT4,
we were able to take advantage of tried-and-true performance
improvements, such as increased cylinder-head flow and higher
compression ratio, as well as newer technologies such as Variable
Valve Timing (VVT).”
To achieve its high-performance Dodge Caliber SRT4 configuration,
the aluminium 2.4-litre World Engine block is specially machined for
increased water and oil flow. Unique cast pistons travel within iron
cylinder liners, and are cooled by oil squirters and affixed to
forged connecting rods for high-revving reliability.
Tri-metal bearings are used for the connecting rods and crankshaft
for high-performance durability. A unique oil pump/balance shaft
module keeps the reciprocating assembly well-lubricated and running
smoothly. An external cooler keeps oil temperatures within a safe
The aluminium cylinder heads are also a World Engine casting
equipped with unique high-temperature exhaust valves. VVT uses
computer mapping to open and close intake and exhaust valves at
optimal points for efficient combustion and flow. The camshaft and
micro-alloy steel crankshaft, shared with the non-turbocharged
2.4-litre World Engine, are fully capable of handling these
Free-flow induction begins with an all-new air cleaner assembly that
draws through an opening in a front chassis cross member for
proximity to cool air. The air is then compressed in a TD04
turbocharger specially configured for the engine’s inlet and outlet
packaging requirements, and sent through an intercooler to a 57mm
Fuel is provided by a high-flow pump feeding injectors developed
specifically for the Dodge Caliber SRT4. An all-new engine
management system designed by Siemens – the Global Powertrain Engine
Controller – keeps the powerplant running at maximum efficiency and
On the exhaust side, spent gases exit through a free-flow system
that features two catalytic converters – one immediately downstream
from the turbo, and another further along the 7.5cm (3 in.)
single-pipe exhaust system. Using two catalytic converters in this
way provides significantly better “light-off” for decreased
emissions. As with the previous-generation Dodge SRT4, the exhaust
is tuned for maximum performance while meeting U.S. federal,
international and European noise regulations.
Power is transferred through a dual-mass flywheel to the six-speed
manual transaxle. The dual-mass flywheel consists of two flywheels
sandwiching internal springs that are specially tuned to reduce
noise and vibration. The Getrag DMT-6 six-speed transaxle, equipped
with a limited-slip differential for uniform side-to-side power
transfer, is capable of handling up to 407 Nm (300 lb.-ft.) of
Torque is sent to the Dodge Caliber SRT4’s front wheels through
equal-length halfshafts sourced from Chrysler Group mid-size cars
for their larger size and power-handling capability.
Dodge Caliber SRT4 Safety and Security Features
Following are safety and security features in the all-new Dodge
• Advanced multi-stage front air bags: offer enhanced protection for
a range of occupants and are designed to identify the size of an
occupant in the front passenger seat based primarily on weight
• Anti-lock braking system: equipped with electronic sensors that
help prevent wheel lockup, the ABS system offers improved steering
control under extreme braking and/or slippery conditions
• Auto-reverse sun roof: an advanced sensing system that
automatically engages and reverses the sun roof to the open position
if it senses an obstacle
• BeltAlert: sounds a periodic chime to alert the driver and all
occupants to fasten their seat belts if they have not buckled-up
• Brake Assist: the vehicle senses a panic brake condition and
applies maximum braking power, providing the shortest possible
• Child seat anchor system (ISOFIX): this system helps ease the
installation of compatible aftermarket child seats
• Constant Force Retractors (CFR): a mechanical device in each front
seat belt is designed to mitigate 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 seat-belt webbing
in a controlled manner during a severe impact
• Electronic Stability Programme (ESP): aids the driver in
maintaining vehicle directional stability, providing oversteer and
understeer control to maintain vehicle behaviour
• Enhanced Accident Response System (EARS): in the event of an
impact, this system makes it easier for emergency personnel to see
and access occupants by automatically turning on interior lighting
and unlocking doors after air bag deployment. The system also shuts
off the flow of fuel to the engine
• Height-adjustable seat belts: allow passengers to lift and lower
the shoulder belt to a comfortable level. Encourages seat belt usage
by offering a more comfortable fit
• Knee bolsters: the steering column, lower instrument panel and the
glove-box door are reinforced to protect unbelted occupants during
frontal impacts. They both restrain and position the occupant
properly and enable air bags to work effectively
• Remote keyless entry: locks and unlocks doors, and turns on
interior lamps. If the vehicle is equipped with a vehicle-theft
security alarm, the remote also arms and disarms that system
• Seat-belt Pretensioners: during a collision, impact sensors
initiate front seat belt pretensioners to immediately remove slack
from seat belts, which reduces the forward movement of an occupant’s
head and torso
• Sentry Key® Engine Immobiliser: utilises an engine key that has an
embedded transponder with a pre-programmed security key code. If the
correct key is not used, the engine will shut off after only a few
• Supplemental side-curtain air bags: standard side-curtain air bags
extend protection to front- and rear-seat outboard occupants. Each
side air bag has its own impact sensor in order to autonomously
trigger the air bag on the side where the side impact occurs
• Tyre Pressure Monitoring (TPM): this advanced system monitors tyre
pressure and alerts the driver to improper tyre pressure conditions.
Low pressure on any tyre illuminates the amber warning indicator in
the instrument cluster
Street- and Track-tested Quality
The all-new Dodge Caliber SRT4 was designed and engineered under the
Chrysler Development System (CDS), the comprehensive, coordinated
and disciplined product-creation process that improves quality and
speed-to-market while reducing costs and encouraging practical
innovation in new vehicles.
CDS emphasises systems engineering, design and up-front planning to
avoid time-consuming and costly trial-and-error methods, or changes
during the later phases of the product development cycle. With CDS,
all product and process planning is completed and fully integrated
before production tooling begins.
Dodge Caliber SRT4 development also encompasses actual conditions,
both on the street and on the race track. To simulate real-world
conditions, the Caliber SRT4 will have logged nearly 3.2 million
customer-equivalent road kilometres (2 million miles) by the time
vehicles begin appearing in dealerships.
To ensure its track-ready character, extensive durability testing of
the Dodge Caliber SRT4 has been undertaken at the Firebird Raceway
in Phoenix; Texas Motorsports Ranch in Fort Worth, Texas; and Nelson
Ledges in Garrettsville, Ohio.
Process, Productivity Key to Manufacturing Excellence
The all-new Dodge Caliber SRT4 is built at the Chrysler Group’s
Belvidere (Illinois, USA) Assembly Plant on the same assembly line
with the Dodge Caliber S, SE, SXT and R/T models.
Previously the home of the Dodge Neon, the plant recently underwent
a multimillion-dollar upgrade to prepare for Caliber production. A
new body shop and other upgrades are part of a total program
investment of $419 million that was announced in January 2005. The
robotic body shop can build the Dodge Caliber SRT4, Caliber and
potentially three other vehicles with no negative impact on
production. Robots can make necessary tool changes automatically
within cycle time, in about 45 seconds.
For Europe and other international markets, the Dodge Caliber SRT4
will be available beginning in late 2007.
Dodge sold more than 1.4 million vehicles worldwide in 2005. With a
U.S. market share of 7 per cent, Dodge is the fifth-largest
nameplate in the United States and the eighth-largest nameplate in
the automotive industry. The Dodge global portfolio includes a range
of cars, trucks, minivans and SUVs. In calendar year 2005, Dodge
sold 10,772 units in limited markets outside North America, an
increase of 19 per cent over 2004.
Dodge Caliber spearheaded the Dodge brand’s expansion into volume
markets outside North America in 2006, and it will be followed by
the Dodge Nitro and the high-performance Dodge Caliber SRT4 in 2007.
Strong Caliber sales continued in August as the vehicle marked its
third full month of availability outside North America. A total of
6,900 Caliber units were sold in international markets through
August, and the Caliber became the number two-selling model for the
month of August (with 2,365 units).
