The all-new Dodge Viper made its long-awaited return in 2013. The latest iteration of this American classic is full of new technologies and ergonomic improvements, while respecting its legacy of American craftsmanship and visceral performance.
The Viper's iconic 8.4L V10 engine pumps out over 481kw (645hp)
Powering the Viper is an all-aluminium 8.4L V10 engine that delivers 481kw (645hp) and 813nm (600lb-ft) of torque — the most torque of any naturally aspirated sports car engine in the world.
The newest Dodge Viper ACR (American Club Racer) launched in 2016 and has taken the performance car world by storm by becoming the indisputable “ultimate street-legal race car” with more track records than any production car in the world — a total of 13 road course lap records as certified by the Sports Car Club of America.
AWE-INSPIRING V10 POWERTRAIN
The heart and soul of the SRT Viper is its venerable, handcrafted, all-aluminium 8.4L mid-front V10 overhead-valve engine.
Improvements in the new Viper include an ultra-high-flow, lightweight composite intake manifold; high-strength, forged pistons; sodium-filled exhaust valves; new catalysts to ease backpressure and an aluminium flywheel that reduces reciprocating losses. Over 11kg has been shaved from the previous engine.
Performance ratings for the SRT-engineered V-10 Viper are 481kw (645hp) and 813nm (600lb-ft) of torque – the most torque of any naturally aspirated sports-car engine in the world.
The Tremec TR6060 six-speed manual transmission has been improved with closer gear ratios and a final drive ratio that has been shortened to 3.55 from 3.07. The shifter throw also is shorter. As a result, the Viper models will be more engaging to drive. Its top speed of 332km/h (206mph) is now achieved through 6th gear with maximum engine speed (redline) at 6,200 rpm.
RIDE AND HANDLING
Starting with a stiffer structure that provides 50 percent more torsional rigidity, the new SRT Viper chassis benefits from numerous enhancements – many learned through racing efforts with Viper GTS-R and Competition Coupe models.
Major upgrades include the addition of a new aluminium x-brace under the hood that ties the suspension pickup points to the magnesium cowl super casting. This benefits torsional rigidity and stiffness. A new aluminium impact beam at the front of the car contributes to overall mass savings and improved weight distribution, while providing excellent crashworthiness.
Structurally, many chassis components were reworked to take advantage of new materials able to accommodate reduced thickness and complex shapes without compromising structural rigidity. The result is an overall weight savings of approximately 45kg.
At the rear, the suspension has been re-engineered with the toe link moved forward of the axle for better tow control and dynamic stability.
A new, driver-selectable two-mode suspension system, featuring Bilstein DampTronic Select shock absorbers with both street and track settings, is standard on GTS models.
SRT Viper models ride on standard Pirelli P Zero, Z-rated tyres with substantially improved overall response, cold-weather performance, and enhanced grip and steering feel, regardless of road surface – while also broadening the performance envelope.
Standard safety technologies such as electronic multistage stability control and traction control help to maximize traction performance at virtually any speed and driving environment.
While every SRT Viper leaves the factory floor ready to take on any on-road or on-track challenge, the available Track Package further enhances its capability by elevating at-limit performance. Slotted two-piece lightweight rotors from StopTech replace the original equipment, while ultra-lightweight multi-spoke Sidewinder II wheels wrapped in high-performance Pirelli P Zero Corsa ‘racing-type’ compound tyres further reduce unsprung weight at all four corners. Selecting the Track Package also slices 26kg from the vehicle’s curb weight.
All new Viper models feature a steering-wheel-mounted launch-control switch, allowing for optimal acceleration from standing starts.
Brake performance for the SRT Viper is engineered to provide shorter stopping distances, better modulation, improved durability and balanced brake performance without fading under extreme conditions.
Each corner features four-piston Brembo brakes with fixed-aluminium calipers and vented rotors boasting a diameter of 355mm by 32mm. Brake calipers are forged. All surfaces are machined for full weight optimisation. The calipers are among the stiffest available. Heat distortion is nearly eliminated, even under the most demanding braking conditions.
The available SRT Track Package features lightweight and slotted two-piece rotors from StopTech.
INTERIOR CRAFTSMANSHIP AND TECHNOLOGY
The all-new, driver-oriented interior cabins of the SRT Viper models have been totally revamped. Superior craftsmanship, premium material appointments and performance-oriented technologies are evident throughout.
All major interior surfaces are sewn and wrapped with additional padding applied in comfort areas. On the Viper GTS model, all surfaces are fully leather-skinned. Standard accent colours are applied to the seats, doors, centre console and stitching.
Quality fit and finish is showcased across the lineup by details such as the triple paint-finished gun-metal appliqués on the cluster bezel, HVAC outlets, window-switch bezels, shifter base, park-brake bezel and the integrated passenger grab-handle on the centre console.
Standard high-performance racing seats from Sabelt feature a lightweight Kevlar/fibreglass shell created by a state-of-the-art resin transfer-moulding technology for mass reduction and long-term durability. Both driver and passenger enjoy improved comfort from thigh support and deep side-bolsters designed to match the extreme lateral acceleration capabilities of the SRT Viper.
Seating positions in the SRT Viper models are 20 mm lower for more room and enhanced performance-driving ergonomics. Seat travel is extended by 90mm overall, which enables expanded seating options from a more rearward positioned bulkhead. For the first time, seat height can be adjusted by up to 40 mm – manually on the SRT model and power-controlled on the GTS.
The new Viper is the most spacious model in the history of the nameplate. The floor pan and bulkhead have been extended approximately 90 mm to provide improved legroom and more rearward seat track movement.
A 7-inch, full-colour, customisable instrument cluster – with its full-time analog tachometer – is designed specifically for the SRT Viper.
The dominant centre tachometer display features an animated readout that glows red and shows off the new ‘Stryker’ logo when engine rpm approaches redline, safely alerting the driver to upshift.
Drivers can configure the tachometer to display their last shift point and a peak rpm hold marker can be set up for optimum performance. Views include tach-only or tach with digital speed readout.
The customisable instrument cluster provides an unmatched presentation of the exclusive SRT Performance Pages’ statistics and feedback to the driver, including 0-to-60mph; 0-to-100mph; eighth- and quarter-mile elapsed times; braking distance; instant g-force measurement readouts and top-speed performance.
AGGRESSIVE AND FUNCTIONAL EXTERIOR
The all-new, timeless exterior design blends contemporary execution with evolutionary refinement.
All-new carbon-fibre hood, roof, decklid and aluminium door panels are firsts for SRT Viper models resulting in significant weight reduction, improved high-speed stability and a .369 drag coefficient while still achieving negative lift.
The forward-hinged hood carries the redesigned Viper badge – aptly named “Stryker” by the Viper Club of America – positioned in the centre; and offers unobtrusive access to several service points and the SRT-engineered V10 powerplant.
The classical low-stance and the extreme cab-rearward proportions that have become the unmistakable silhouette of the iconic supercar, return on the 2013 SRT Viper models along with the dramatic fender “gills” – another traditional Viper design cue that helps to extract heat from the engine compartment.
The Viper models feature a contemporary take on the traditional “double-bubble” roof configuration that maximises headroom for the driver and passenger while maintaining a low frontal area – allowing additional room for helmets during recreational competitive driving.
Dual-function, bi-xenon projector headlamps are tightly packaged with white light-emitting diode (LED) daytime running lamps and LED turn signals in a sinister “snake eye” configuration.
Functional “blisters” incorporated into the 70 mm projector headlamp lenses create a three-dimensional view that gives Viper a distinctive glare.
The lower-front grille is purposefully designed as an evolution of the traditional Viper low-profile cooling opening configuration and discretely carries a refined V-shape structure.
The exhaust system continues to exit forward of the rear wheels and now carries further refinement with cast aluminium, sill-mounted exhaust bezels.
For the first time, the 2013 SRT Viper models carry LED taillamps that integrate stop-and-turn illumination in one element. Snakeskin texture in the lens carries the surface work seen in the gills and hood textures. With dark-masked lenses, the horizontal lamps appear dark until the LED elements fire. Each lamp carries 50 LEDs that provide a unified “crystallised” illumination effect.
The five-spoke, forged-aluminium “Rattler” wheel design on the 2013 Viper model is available with fully polished (standard), fully painted Hyper Black or fully painted Matte Black finishes.
The Viper GTS has a split six-spoke forged-aluminium “Venom” wheel design with three available finishes, including polished face with graphite-painted pockets (standard), fully painted Hyper Black or fully painted Matte Black.
Available SRT Track Package wheels are ultra-lightweight, track-ready wheels in Hyper Black or Matte Black finishes.
A mixture of classic Viper exterior paint shades have been reformulated, while new colours have been introduced during a multistage painting process that results in show-car like finishes.
Designed and built with premium features and materials inside and out, the Viper GTS competes with the best performance vehicles in the world – and does so with a wide range of creature comforts, advanced drivetrain and interior technologies.
