Dodge Introduces Street-legal 2008 Viper SRT10 ACR
* Dodge delivers ultimate purpose-built, street-legal track car
* 2008 Dodge Viper SRT10 ACR offers reduced weight, race-ready
hardware and competition tuning for optimal on-track performance
* Aerodynamic improvements, racing suspension and weight savings
equal unmatched performance for under $100,000
Auburn Hills, Mich., Nov 9, 2007 - Dodge announced today that the
all-new 2008 Dodge Viper SRT10 ACR short for American Club Racer
will make its public debut at next week's Los Angeles Auto Show.
The latest addition to Chrysler LLC's Street and Racing Technology
(SRT) family of performance vehicles, the all-new, 600 horsepower
2008 Dodge Viper SRT10 ACR is a street-legal Viper engineered to
dominate on the race track. Because it is street legal, die-hard
Viper and track enthusiasts can drive their car to the race track,
run it at top speed on the track and then drive it home.
"With the all-new 2008 Dodge Viper SRT10 ACR, SRT has taken the
ultimate American sports car and injected it with an extra dose of
racing DNA," said Mike Accavitti, Director - Dodge Brand and SRT
Global Marketing and Communications, Chrysler LLC. "With the Viper
SRT10 as the starting point, SRT engineered a combination of reduced
weight, race-tuned suspension and aerodynamic improvements to create
the ultimate Viper for the street and track."
Derived from the all-new 2008 Dodge Viper SRT10, the heart and soul
of the all-new 2008 Viper SRT10 ACR is SRT's new 8.4-liter aluminum
V-10 engine that produces 600 horsepower and 560 lb.-ft. of torque.
The 2008 Dodge Viper SRT10 ACR stays true to the five key aspects of
SRT: standout powertrain, bold exterior styling, race-inspired
interior, benchmark braking and world-class ride and handling
characteristics across a dynamic range.
Bold Exterior Styling
The 2008 Dodge Viper SRT10 ACR exterior styling cues offer not only
bold aesthetics, but functional benefits on the track. These include
a variable geometry "fanged" front splitter, an adjustable rear wing
sculpted by CFD (Computational Fluid Dynamics) and optimized front
dive planes. These new aerodynamic devices are formed in
high-performance autoclaved carbon-fiber. By using both
unidirectional and woven laminates, the aero equipment is optimized
for the minimum weight possible.
The splitter and dive planes feature a clear-coated carbon-fiber
weave on all Viper SRT10 ACR models.
The front splitter includes three removable rub strips that provide
protection and wear resistance. Supported by stainless steel tension
cables, the splitter is designed to absorb the energy from minor
The Dodge Viper SRT10 ACR aerodynamics are tuned and balanced to
maximize downforce and provide increased levels of lateral grip.
Each Viper SRT10 ACR also includes a track extension that replaces
the center splitter rub strip and fills out the fanged splitter
scallop for closed-circuit events. The aerodynamic effect of the
track extension is a reduction in overall drag and an increase in
front downforce of nearly one-third.
The front fog lamps have been deleted and replaced with lightweight
The 2008 Viper SRT10 ACR features a signature two-tone paint scheme
with a black center section. An optional driver's stripe is
available on a two-tone Viper Red or a Viper Black ACR. The driver's
stripe also features a sewn leather accent on the steering wheel. A
clear-coated exposed weave is featured on the rear carbon-fiber wing
of all two-tone and driver's stripe Viper SRT10 ACR models.
A standard Viper SRT10 monotone paint scheme is also available
featuring a body-color rear wing and dual painted Viper stripes.
The 2008 Dodge Viper SRT10 ACR is available in five colors: Viper
Red, Viper Black, Viper Violet, Viper Bright Blue Metallic and Viper
Lightweight forged aluminum Sidewinder wheels are painted gloss
black to complete the one-of-a-kind exterior styling.
Based on the 2008 Dodge Viper SRT10 interior, the Viper SRT10 ACR
goes a step further to satisfy what racers want: the least weight
possible. An optional "Hard Core" package offers maximum weight
savings by deleting the audio system, underhood silencer pad, trunk
carpet and tire inflator. The radio is replaced by a lightweight
cover that can be configured to mount the included lap timer. The
door speakers are replaced by lightweight carbon-fiber panels. The
Hard Core package offers a 40 lb. weight savings and provides
ultimate street-legal race-ready performance.
World-class Ride and Handling
The all-new 2008 Dodge Viper SRT10 ACR is specifically modified and
tuned for track performance. The ACR suspension includes coil-over
racing dampers from KW Suspensions that are adjustable for damping
and ride height. The shocks are two-way adjustable without removing
the wheels a timersaver on the track and they include a large
range for compression and rebound. The KW dampers and forks are
machined from solid aluminum billet, feature spherical bearing
mounts, and are optimized to minimize weight and maximize
The 2008 Dodge Viper SRT10 ACR features a new front stabilizer bar
for increased roll-stiffness.
Lightweight forged aluminum Sidewinder wheels are optimized by using
Finite Element Analysis to achieve a lower rotating unsprung mass.
Finished in gloss black paint, they wear Michelin Pilot Sport Cup
DOT-approved (street-legal) race tires, providing enhanced grip on
Track performance is maximized in the 2008 Dodge Viper SRT10 ACR via
several weight-savings initiatives. The savings were achieved with
the Michelin Pilot Sport Cup Tires, Sidewinder lightweight wheels
and StopTech brake rotors. With the aerodynamic and suspension
elements, the 2008 Dodge Viper SRT10 ACR is 40 pounds lighter than
the Viper SRT10 coupe. The optional Hard Core package further
reduces the weight by another 40 pounds, for a total weight savings
of 80 pounds.
The Viper SRT10 benchmark brakes are taken to the next level in the
2008 Dodge Viper SRT10 ACR. StopTech two-piece, slotted lightweight
rotors combine with the Viper SRT10's Brembo calipers to reduce
rotating inertia and unsprung mass, improve brake cooling, and
significantly reduce fade even under extreme conditions. The
StopTech rotors feature a patented curved-fin design, a key element
in improving brake cooling. The StopTech brake rotors combined with
the Michelin Pilot Sport Cup Tires and Sidewinder lightweight wheels
combine to reduce 60 pounds of unsprung, rotating mass. The 2008
Dodge Viper SRT10 ACR stops from 60 mph in less than 100 feet.
The 2008 Dodge Viper SRT10 ACR utilizes the Viper SRT10's new
8.4-liter aluminum V-10 engine that produces a ground-shaking 600
horsepower and tire-smoking 560 lb.-ft. of torque. It features a
deep-skirted V-10 aluminum engine block, cylinder heads equipped
with Computer Numerically Controlled (CNC)-shaped combustion
chambers, large valves and Variable Valve Timing (VVT). VVT
Electronically adjusts when the exhaust valves are open and closed
according to engine speed and load, allowing the engine to "breathe"
cleaner and more efficiently.
The two-piece intake manifold combines cast aluminum lower with
smooth runners for better air flow, bolted to a die-cast aluminum
upper plenum. A revised air-cleaner box with a low-restriction
filter sends air through a dual electronic throttle control into the
The air-fuel mixture in the cylinders is ignited by platinum-tip
spark plugs fired by individual plug coils mounted on the
Within the cylinders, pistons are equipped with large-diameter
floating pins with bronze bushings for high-load capability. Forged
powder-metal connecting rods are secured with aircraft-quality
fasteners for increased fatigue strength.
Engine lubrication is managed by the large oil pump and a swinging
oil pickup adapted from Viper competition engines, to ensure proper
oil pressure in high-rpm and hard-cornering conditions.
The 2008 Dodge Viper SRT10 ACR sports the latest evolution of the
Tremec T56 six-speed manual transmission known as the TR6060. Power
is transmitted to the rear wheels via a GKN ViscoLok speed-sensing
The 2008 Dodge Viper SRT10 ACR will be hand built at the Conner
Avenue Assembly Plant in Detroit.
The 2008 Dodge Viper SRT10 ACR will arrive in showrooms in the
second quarter of 2008 at a U.S. Manufacturer's Suggested Retail
Price (MSRP) of less than $100,000. Complete pricing information
will be released at a later date.
