2013 SRT Viper GTS

The SRT Viper GTS builds on the DNA of the SRT Viper model with more technologically advanced solutions, like two-mode active suspension, to allow this world-class GTS to find new limits on the track. The Viper GTS features dual extractors to give the hood a more refined and organic look. The interior cabin of the GTS model features hand-cut, sewn-and-wrapped Nappa leather soft-touch surfaces throughout, including the leather-wrapped instrument panel, center console, doors and A pillars. A variety of selectable colors are provocatively applied to the leather-appointed areas where the body comes in contact, including the doors, seats, console and HVAC outlet accents. Standard quality stitching is used in matching interior colors on the GTS model. Available interior color combinations on the Viper GTS model include black, black/Header Red and black/Caramel. An optional GTS Premium Interior Package features SRT Laguna premium leather surfacing throughout the entire cabin in either black or Sepia. Unique embossments are designed into the door bolsters, seats and the storage bag while a new Alcantara headliner completes the package.

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 low-gloss black. Specially formulated, Pirelli P-Zero, Z-rated performance compound tires are new for the SRT Viper. Up front, tires measure P295/30ZR18 and rear tires are P355/30ZR19. Final tuning of the new tires has demonstrated improved lap times and higher skidpad grip with the new tires. The new tires provide improved cool and wet weather performance and are tuned to give the driver better road feel.

On GTS models, gas-charged, monotube Bilstein Damptronic Select, aluminum-bodied shock absorbers equipped with large 46 mm pistons are new for 2013. The new two-mode shocks feature both street and track settings. Shock damping is driver selectable through a two-position switch located on the console within easy reach for the driver. Valving in track mode is optimized for track use to extract maximum grip from the tires. In street mode, the shocks are designed to provide a compliant ride on the various types of pavement and road conditions, while still providing damping levels appropriate for the extreme capabilities of the SRT Viper GTS. Spring rates on the Viper model’s passive-shock package have decreased 5 percent, while spring rates on the Viper GTS model’s Damptronic package have increased 5 percent for a 10 percent difference between the two packages.

For the first time the SRT Viper models will include both electronic stability control (ESC) and traction control systems. The Viper GTS model features a four-mode ESC system includes speed sensors located at each wheel along with a yaw sensor, lateral G and steering-wheel angle sensor. The system is tuned to be fully track capable in all modes, including “Full On.” Two graduated levels of stability and traction control are available in addition to “Full Off.” This allows the driver to progressively reduce the amount of assist, as driver experience, skills and confidence are gained.

With the system in Full On, drivers receive the maximum benefits of both the traction control system and stability control without unnecessary intrusion and the full cornering capability of the vehicle is realized. Sport mode allows more longitudinal and lateral slip before the traction control and stability control system are engaged. For competition, the Track mode has no traction control while the higher limits of Sport Mode stability control are maintained. In Full Off mode, both the traction control and stability control are disabled with the anti-lock braking system (ABS) remaining active. A steering-wheel mounted button enables the driver to select the optimal mode depending on road conditions or preference. A telltale graphic in the instrument cluster advises the driver which setting is activated in the ESC system.

To help maximize straight-line performance in track conditions, all SRT Viper models will include launch control as standard equipment. Operational in any ESC mode, the system is engaged by a button on the steering wheel. When the vehicle is at a complete stop, the driver engages the system and then quickly applies full throttle. Launch control holds the engine at optimal launch rpm and waits for the driver to release the clutch. Launch control then uses engine throttle only to achieve controlled wheelslip for maximum acceleration through first gear.
