The 2008 Dodge Viper SRT10 brought even more 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.
The Viper Roadster features the same incredible perfomance as the coupe, all within the stunning convertible exterior.
The Dodge Viper SRT10 ACR provides an enhanced driver experience and even better performance, with enhanced suspension featuring high-performance aluminium control arms and knuckles, KW suspension with two-way adjustable competition coil-over shock absorbers with remote reservoirs. The carbon-fibre aerodynamic package, lightweight wheels, two-piece slotted StopTech brake rotors and Michelin PS Cup tyres round out the package.
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 V10 aluminium engine block was revised for a 1mm larger bore, raising the displacement to 8.4 litres from 8.3 litres. 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 8.4L 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 V10’s two-piece intake manifold combines a cast aluminium lower with smooth runners for better air flow, bolted to a die-cast aluminium upper plenum. A revised air-cleaner box with a low-restriction filter sends air through a dual electronic throttle control into the intake module.
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 8.4L V10’s increased horsepower and torque levels, while improving traction, driveability – and durability.
The 2008 Dodge Viper SRT10’s V10 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 synchroniser package. A new shifter system results in reduced shifter travel. Club racers will applaud a new provision for adding an external transmission cooler.
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 33m.
RACE-BRED 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 aluminium 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 aluminium, 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 tyres. The four-groove tread-design tyres 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 8.4L, 600-horsepower V10 engine underneath.
Eight exterior colours 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 five dual painted stripe colours available: white, black, silver, graphite 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.
The new-for-2008 Dodge Viper SRT10 Roadster and Coupe cockpit retains its characteristic red push-button starter and performance-oriented, highly functional instrument panel with centre-mounted tachometer and 220-mph speedometer.
Five interior colours will be available in 2008: black, and four new colour combinations in black/red, black/blue, black/slate or black/natural tan. A choice of bezel finishes on the centre instrument panel and console adds to the increased level of customisation.
The Viper's race-inspired interior design creates a cockpit around the driver to provide the perfect environment to unleash the incredible performance available.
