The new 2013 Dodge SRT Viper and SRT Viper GTS which unveiled at the 2012 New York Auto Show offer new interior and exterior designs with premium materials and new interior surfaces with aerodynamically functional details that are perfectly integrated to the carbon fiber and aluminum skin.

The Dodge SRT Viper GTS builds on the DNA of the SRT Viper model with more technologically advanced solutions, like two-mode active suspension, to allow the GTS to find new limits on the track while also opening up its envelope as a more premium and mature evolution of the classic, extreme performance formula.

Powering the 2013 Dodge SRT Viper is the venerable, hand-assembled 8.4-liter all-aluminum, V-10 overhead-valve engine. Improvements for 2013 include a new, ultra-high flow and lightweight composite intake manifold, high-strength forged pistons, sodium-filled exhaust valves, new catalysts to reduce back pressure and an aluminum flywheel that reduces reciprocating losses. More than 25 pounds has been shaved from the fully dressed engine.

Preliminary performance ratings for the SRT-engineered V-10 Viper are 640 hp and 600 lb.-ft. of torque – the most torque of any naturally aspirated engine in the world.

The Tremec TR6060 six-speed manual transmission has been improved with a shorter throw shifter, closer gear ratios and a final drive ratio that has been shortened to 3.55 from 3.07. The 2013 Viper models will be more engaging to drive and top speed is now achieved through 6th gear with maximum engine speed (redline) at 6,200 rpm.

Starting with a stiffer structure that provides 50 percent more torsional rigidity, the chassis of the 2013 Dodge SRT Viper benefits from numerous enhancements – many learned through racing efforts with Dodge SRT Viper GTS-R and Competition Coupe models.

Major updates include the addition of a new aluminum “X” brace under the hood that ties the suspension pickup points to the magnesium cowl super casting and contributes to improved torsional rigidity and stiffness. A new aluminum impact beam at the front of the car contributes to overall mass savings and improved weight distribution while providing excellent crashworthiness.

Structurally, many areas of the chassis were reworked to take advantage of new materials, reduce thickness in some areas and reshape components for more structural rigidity in others. The result is an overall weight savings of approximately 100 pounds.

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.

For 2013, Dodge SRT Viper models ride on standard Pirelli P Zero, Z-rated tires with substantially improved overall performance, cold weather performance, enhanced overall grip and steering response on a variety of road surfaces while also broadening the performance envelope. An optional SRT Track Package features Pirelli P Zero Corsa, “soft”-tuned, “racing-type” compound tires that improve handling and precision further on the road or the race track.

For the first time, standard safety technologies such as electronic stability control and traction control help to maximize traction performance at virtually any speed and driving environment.

All 2013 Viper models will come with a steering-wheel-mounted launch control switch, allowing for optimal acceleration from standing starts.

Stopping performance for the 2013 Dodge SRT Viper is engineered to provide shorter stopping distances, better modulation, improved durability and balanced brake performance without fading under extreme conditions.

Four-piston Brembo brakes with fixed-aluminum calipers, and vented rotors with a diameter of 355 mm by 32 mm, are used at all four corners. Brake calipers are forged and weight optimized by fully machining all surfaces. The calipers are among the stiffest available with distortion from heat nearly eliminated even under the most demanding braking conditions.

The available SRT Track Package features lightweight and slotted two-piece rotors from StopTech.

For the first time, all major interior surfaces are sewn and wrapped with additional padding applied in comfort areas. On the Dodge SRT Viper GTS model, all surfaces are fully leather skinned, and standard accent colors are applied to the seats, doors, center console and stitching.

Quality fit and finish across the lineup is showcased by 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 center console.

Standard high-performance racing seats from Sabelt feature a lightweight Kevlar/fiberglass shell created by a state-of-the-art resin transfer molding 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 position in the 2013 Dodge SRT Viper models is 20 mm lower for more room and enhanced performance-driving ergonomics. Seat travel is extended by 90 mm 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 floor pan and bulkhead have been extended approximately 90 mm to provide improved legroom and more rearward seat track movement.

Designed specifically for the 2013 Dodge SRT Viper, the new 7-inch, full-color, customizable instrument cluster display uses a full-time analog tachometer readout in the center to confirm the performance driving feedback philosophy of the Viper. Drivers have a wide range of custom and personal options such as additional digital speedometer readout just below the tachometer.
