Even More Venom: Dodge Unleashes New 600-horsepower
2008 Viper SRT10
The new 2008 Dodge Viper SRT10 boasts more of what performance
aficionados crave: kick-in-the-pants, throw-back-in-the-seat power,
combined with benchmark braking, world-class ride and handling, a
race-inspired interior and bold exterior styling.
While every SRT vehicle offers balanced, overall performance, the
heart and soul of the new 2008 Dodge Viper SRT10 is its standout
powertrain. For 2008, SRT ups the ante with a new, 8.4-liter aluminum
V-10 engine that produces an astounding 600 horsepower and 560 lb.-ft.
of torque.
"A legendary big-game hunter once said, 'Bring enough gun!' - and
with the new 2008 Dodge Viper SRT10, we've created some very powerful
artillery for sports-car enthusiasts," said Kipp Owen, Director - Street
and Racing Technology (SRT) Engineering, Chrysler Group. "With 600
horsepower - 90 more than before - and 0-to-60 performance in less than
four seconds, the 2008 Dodge Viper SRT10 sets a new benchmark for the
ultimate American sports car."
The new 2008 Dodge Viper SRT10 will arrive in Dodge showrooms in
North America this summer with a new level of customization options,
including five new exterior colors, four new interior color combinations
and a new wheel design.
Standout Powertrain
When SRT powertrain engineers set out to get more venom from the 2008
Dodge Viper SRT10's powerplant, their objectives included not only
increasing performance, but also complying with stringent regulatory
requirements, such as federal Tier 2, Bin 5 and California's Low
Emissions Vehicle (LEV) 2 mandates.
Working with specialists from McLaren Performance Technologies and
Ricardo, Inc., SRT engineers began by following the racer's basic
formula for more power: bigger displacement, more efficient breathing
and higher engine speed.
The new Dodge Viper SRT10's deep-skirted V-10 aluminum engine block
was revised for a 1-millimeter larger bore, raising the displacement to
8.4 liters from 8.3 liters. With strengthened bulkheads and improved
water jackets for better cooling, the block includes pressed-in iron
cylinder liners and cross-bolted main bearing caps for strength and
durability.
The Viper SRT10's 8.4-liter engine breathes through new cylinder
heads equipped with Computer Numerically Controlled (CNC)-shaped
combustion chambers, larger 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 2008 Dodge Viper SRT10 V-10's two-piece intake manifold combines
a 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 intake module.
The air-fuel mixture in the cylinders is ignited by platinum-tip
spark plugs fired by new individual plug coils mounted on the
cylinder-head covers.
Within the cylinders, pistons are equipped with larger-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 a larger oil pump and a swinging oil
pickup adapted from Viper competition engines, to improve oil pressure
in high-rpm and hard-cornering conditions.
Spent gases exit through tubular air-gap headers, which not only
improve exhaust flow, but also ensure quick catalyst light-off for
improved emission control. The headers' stamped stainless-steel outer
shell acts as a thermal heat shield for the individual stainless-steel
runners that contribute to better flow separation and exhaust tuning.
SRT engineers didn't stop there. Upgrades were developed to handle
the 8.4-liter V-10's increased horsepower and torque levels, while
improving traction, driveability - and durability.
The 2008 Dodge Viper SRT10's V-10 channels its power through a new,
smaller-diameter, twin-disc clutch (a change from the previous
larger-diameter, single-disc setup). The new clutch reduces rotating
inertia by 18 percent, resulting in reduced clutch-pedal effort and
improved engagement feel.
The transmission is the latest evolution of the Tremec T56 six-speed
manual, known as the TR6060. It features 10 percent wider gears for
higher torque capacity and a new synchronizer package. A new shifter
system results in reduced shifter travel. Club racers will applaud a new
provision for adding an external transmission cooler.
Benchmark Braking
Stopping power is another key attribute of the Dodge Viper SRT10
formula, with 14-inch brake rotors gripped by Brembo 44/40 dual opposing
piston calipers in the front and Brembo 42/38 dual opposing calipers in
the rear. An anti-lock braking system (ABS) prevents lockup during hard
braking. This system results in a benchmark braking performance of
60-to-0 mph in less than 100 feet.
World-class Ride and Handling
The ride and handling of the 2008 Dodge Viper SRT10 is defined by a
race-bred, fully independent, four-wheel suspension featuring
lightweight, high-performance aluminum control arms and knuckles, damped
by lightweight coil-over shock absorbers.
Where the power goes right to the road, SRT engineers retained the
tried-and-true Dana M44-4 rear axle and outfitted it with a new GKN
Visco-Lok speed-sensing limited-slip differential for improved traction.
The Dodge Viper SRT10 rides on polished, forged aluminum, 18 x
10-inch front and 19 x 13-inch rear wheels now available in three
styles: the five-spoke, the H-spoke and the all-new Razor wheel with
five U-shaped spokes. The wheels are clad in Michelin® Pilot® Sport PS2
tires. The four-groove tread-design tires provide maximum grip, reduced
road noise and superior handling in both wet and dry conditions.
Bold Exterior Styling
The 2008 Dodge Viper SRT10 remains available in two body styles -
Roadster and Coupe. Both feature a dramatic new hood with a larger, more
efficient hood scoop for air induction and larger, functional hood
louvers to facilitate a greater cooling effect for the more powerful
8.4-liter, 600-horsepower V-10 engine underneath.
Eight exterior colors will be introduced throughout the model year -
five of which are all-new including Venom Red, Snakeskin Green, Viper
Violet, Viper Orange and Bright Blue. Racing stripes continue to be an
option with six dual painted stripe colors available: white, black,
silver, graphite, blue and red.
Several exterior differences exist between the 2008 Dodge Viper SRT10
Roadster and Coupe. In fact, the only body panels they share are front
fascia and fenders, hood and doors. However, all of the iconic Viper
SRT10 design cues have been maintained including the signature crosshair
grille, deep-cut side scallops, swept-back fenders and lowered hood
lines.
The Dodge Viper SRT10 Coupe's hard top with its "double bubble"
styling makes it even more torsionally stiff than the Roadster. The 2008
Dodge Viper SRT10 Coupe offers increased downforce and high-speed
stability with its sloping roofline and deck-lid spoiler. Plus, the
Dodge Viper SRT10 Coupe has an additional 6.25 cubic feet of trunk space
than the Viper SRT10 Roadster, for a total of 14.65 cubic feet. The roof
and headliner structure offer more room to accommodate a safety cage,
while maintaining as much headroom as possible.
Race-inspired Interior Design
The 2008 Dodge Viper SRT10 Roadster and Coupe cockpit retains its
characteristic red push-button starter and performance-oriented, highly
functional instrument panel with center-mounted tachometer and 220-mph
speedometer.
Five interior colors will be available in 2008: black, and four new
color combinations in black/red, black/blue, black/slate or
black/natural tan. A choice of bezel finishes on the center instrument
panel and console adds to the increased level of customization.
"The 2008 Dodge Viper SRT10 delivers die-hard performance enthusiasts
a perfect combination of outrageous power, exceptional performance and
stunning good looks," said Mike Accavitti, Director - Dodge Motorsports
and SRT Marketing and Product Planning, Chrysler Group. "And now with a
whole new range of interior and exterior colors and options to choose
from, the 2008 Dodge Viper SRT10 redefines how a customer can
personalize their Viper." |
