The exterior is characterized by new surfaces with aerodynamically functional details integrated into the carbon fiber and aluminum skin.
The interior features a number of upgrades, for both the material appointments and the onboard technologies.
The heart of the 2013 SRT Viper is its handcrafted, all-aluminum 8.4-liter, mid-front V-10 overhead-valve engine, producing 640 horsepower and 600 lb.-ft. of torque – the most torque of any naturally aspirated sports-car engine in the world.
The top speed is 206 mph, while the 0-100-0 mph sprint takes less than 12 seconds.
Engine improvements for 2013 include an ultra-high-flow, lightweight composite intake manifold; high-strength, forged pistons; sodium-filled exhaust valves; new catalysts to ease backpressure and an aluminum flywheel that reduces reciprocating losses.
The Tremec TR6060 six-speed manual transmission has closer gear ratios and a shortened final drive ratio.
The structure has been stiffened and provides 50 percent more torsional rigidity.
The suggested retail prices (MSRP) for the 2013 SRT Viper and 2013 SRT Viper GTS models are $97,395 and $120,395 (excluding $1,995 destination) respectively.
Below we report the official details on the exterior design.
Among the new features are the all-new carbon-fiber hood, roof, decklid and aluminum door panels which contribute to a 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 center; and offers unobtrusive access to several service points and the SRT-engineered V-10 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 2013 Viper models feature a contemporary take on the traditional “double-bubble” roof configuration that maximizes 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 aluminum, 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 “crystallized” illumination effect.
The five-spoke, forged-aluminum “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-aluminum “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.
For 2013, a mixture of classic Viper exterior paint shades have been reformulated, while new colors are also being introduced during a multistage painting process that results in show-car like finishes.
Six exterior color choices are offered on the SRT Viper models including: Adrenaline Red, Venom Black, Bright White, Gunmetal Pearl, Race Yellow and Shadow Blue Pearl. The SRT Viper GTS model receives an expanded exterior color palette with the availability of Stryker Red Tri-Coat Pearl and GTS Blue.
Two distinctive body stripe configurations are offered. The SRT Viper is available with a pair of tapered stripes starting on the clamshell hood and making their way onto the roof and finishing on the rear hatch. The SRT Viper GTS model is available with a pair of wide stripes running the length of the coupe from front to rear fascia.
Both stripe configurations are expertly applied in the paint booth before the main body color. Only after the paint is cured, a final clear coat is used to ensure the stripes are an integral part of the finished product.
Exterior stripe color packages include: Black Venom, Billet Silver and Gunmetal Pearl. Bright White body-length stripes are being used exclusively on the 2013 SRT Viper GTS Launch Edition model.
