The wait is finally over. Dodge... excuse us, SRT has officially pulled the wraps off the 2013 Viper, and it's everything we were hoping it would be. Let's discuss numbers: 640 horsepower and 600 pound-feet of torque from a front/mid-mounted 8.4-liter V10 and the best power-to-weight ratio of any Viper ever built.

Two models will be available, the standard high-performance SRT and GTS.

In fact, the 2013 SRT Viper's 4.9 pounds per horsepower puts it just behind the Bugatti Veyron and Ferrari F12 and ahead of such performance stalwarts as the Lamborghini Aventador and Chevrolet Corvette ZR1. What's more, this engine has no turbocharger or supercharger, and those 600 lb-ft make this V10 the most torque-rich naturally aspirated production engine in the world.

Two models will be available, the standard high-performance SRT and GTS. The SRT is meant to "offer a perfect blend of extreme performance and a deliberate preservation of what has become the iconic DNA of the Viper," says Ralph Gilles, President and CEO of the Street and Racing Technology Brand and Motorsports. Buyers looking for a little more technology can opt for the GTS, which adds such niceties as a two-mode active suspension and interior creature comforts not normally associated with the Viper.

The 2013 Viper isn't just about power, either. Chassis updates are plentiful and include a beautiful X-brace up front that helps the new platform boast a 50-percent increase in rigidity over the last Viper. To help the driver maintain control, the 2013 Viper is fitted with stability and traction control (both fully defeatable, says Gilles) along with Pirelli P Zero Z-rated tires that were designed specifically for the Viper in massive 355 sizes in back and 295 up front. Three different wheels will be available, with five or six spokes in polished, matte black or gloss black finishes, along with a special lightweight set as part of the SRT Track Package.

Inside, the Viper is more luxurious than ever before, with seats from Sabelt (the same supplier used by Ferrari) and a seven-inch LCD screen directly in front of the driver that's configurable with a whole slew of custom operations. Chrysler's stellar 8.4-inch Uconnect Media Center is also included, as is a Harmon Kardon sound system. Oh, and for the first time ever, cruise control is standard.

For the first time ever, cruise control is standard.

Though first and foremost a street car, SRT fully intends to establish the 2013 Viper's racing credentials early and often. Viper will return to the American Le Mans Series in 2012, fielding a two-car team driven by Dominik Farnbacher, Marc Goossens, Ryan Hunter-Reay and Kuno Wittmer. And gaming fans aren't left out, either – SRT has worked with the Forza Motorsport 4 crew to make sure the 2013 SRT Viper is available soon as DLC.

Auburn Hills, Mich., Apr 4, 2012 -
The all-new 2013 SRT® Viper was unveiled to the world today at the New York International Auto Show, marking its highly anticipated return to the high-performance sports car market.

The fifth generation of the iconic two-seat, American-built supercar has been deliberately evolved to incorporate superior craftsmanship, a host of new technologies and ergonomic improvements while respecting its visceral legacy of outright performance.

"After a gut-wrenching period of uncertainty, the Street and Racing Technology brand team is extremely proud that our hand-built in Detroit, flagship supercar is back and ready to take on the performance car world," said Ralph Gilles, President and CEO – Street and Racing Technology Brand and Motorsports, Chrysler Group LLC. "Beyond being the flagship for the new SRT brand, the launch of the 2013 Viper proves that we simply would not let the performance icon of the Chrysler Group die. Willed to live on by a very special group of performance enthusiasts inside the company and across Viper Nation, this SRT team under our new leadership was challenged to not just continue the legendary Viper, but to create a world-class supercar that would showcase the very best we have to offer."

Two new models for any performance buyer

For the 2013 model year, two new models of the iconic supercar will be hand built at the Conner Avenue Assembly Plant in Detroit – the home for Viper since 1995. Both SRT Viper and SRT Viper GTS models offer new interior and exterior designs incorporating premium materials and new exterior surfaces with aerodynamically functional details that are beautifully integrated into the high-tech carbon fiber and aluminum skin. On the inside, designers and engineers strived to rethink all touch points; and upgrade all material appointments and technologies.

"The SRT Viper model is meant to offer a perfect blend of extreme performance and a deliberate preservation of what has become the iconic DNA of the Viper," Gilles added. "We strove to deliver a supercar that continues to bring the driver as close as possible to the machine."

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 while also opening up its envelope as a more premium and mature evolution of the classic, extreme performance formula. Designed and built with premium features and materials inside and out, the Viper GTS will compete with the best performance vehicles in the world with a wide range of creature comforts, advanced drivetrain and interior technologies.

"We've purposely evolved the iconic soul and raw performance formula that Viper has maintained over the years," Gilles said. "Our returning customers will see the world-class levels of pride, quality and hand craftsmanship built into the 2013 Viper. With two price classes of the SRT Viper and SRT Viper GTS, we have offerings for both the traditional core Viper customer and for the new customer who wants the same performance in a package with more technology and premium creature comforts."

Awe-inspiring V-10 powertrain

At the heart and soul of the 2013 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 horsepower 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.

Outstanding ride, handling and capability

Starting with a stiffer structure that provides 50 percent more torsional rigidity, the chassis of the 2013 SRT Viper benefits from numerous enhancements – many learned through racing efforts with 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, 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.

Benchmark braking

Stopping performance for the 2013 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.

New premium materials, craftsmanship and technologies

The all-new, driver-oriented interior cabins of the SRT Viper models have been totally revamped for 2013 with superior craftsmanship, premium material appointments and performance-oriented technologies.

For the first time, 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, 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 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 new 2013 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.

Designed specifically for the 2013 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 an additional digital speedometer readout just below the tachometer. The vehicle information is clearly communicated with easy-to-understand icons. Intuitively controlled through a simple four-way steering-wheel control, the driver can configure the screens to display the information they desire, easily mixing and matching information.

Uconnect® Access provides new level of connectivity

The 2013 SRT Viper lineup includes the new, next generation Uconnect® Access in-vehicle connectivity system that provides drivers with access to more information, emergency services, more entertainment and improved graphics.

Viper customers can choose between two Uconnect Media Centers, RA3 and RA4, which provide a range of new features and multiple ways to control media in the vehicle. The system includes an 8.4-inch touchscreen along with a set of hard keys for commonly used functions, including traditional knobs for tuning the radio bands and radio volume. Touchscreen buttons along the bottom of the screen allow drivers to easily access the radio, climate controls, navigation, phone, and new, select, certified applications. The new, highly sculpted steering wheel has a host of finger-tip mounted controls for audio, Uconnect, cruise control (first application) and launch control.

SiriusXM Travel Link also is available with Uconnect, providing premium data services and information to make every trip more efficient. SiriusXM Traffic works with the vehicle's navigation system to display traffic speed and traffic flow information along with accident information to assist drivers in routing around congested areas. An expanded SiriusXM channel lineup includes exclusive programming, including the new SiriusXM Latino channels, an auto industry first.

A range of Harman Kardon® surround-sound systems are available across the SRT Viper lineup that feature the latest in audio system technology. All Harman Kardon audio systems include a high-voltage class D amplifier with tracking power supply and up to 11 channels of amplification. The Harman Kardon system with exclusive Logic 7 surround-sound processing is available in the Viper GTS model with a total of 18-speakers, including four subwoofers located behind the seats. All Harman Kardon systems in the 2013 SRT Viper lineup include high-performance, high-efficiency GreenEdge technology loudspeakers that are extremely light and include rare earth magnets. The magnets inside each speaker ensure efficient speaker operation and enhanced performance. The audio systems operate on 32 volts – so the new and improved sound system achieves more than double the acoustic power of the current system.

Refined evolution of SRT's hallmark – aggressive and functional exterior designs

The all-new, timeless exterior design blends contemporary execution with evolutionary refinement.

All-new carbon-fiber hood, roof, decklid and aluminum door panels are firsts for SRT Viper models resulting in significant weight reduction, improved high-speed stability and a slippery .364 drag coefficient.

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 low-gloss 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 low-gloss black.

Available SRT Track Package wheels are ultra-lightweight, track-ready wheels in Hyper Black or matte black finishes.

        Agreed. When you see people driving this car, you'll know it's because they wanted a DRIVER'S car, and actually obtain some sort of mechanical skills to operate such a vehicle, unlike most supercars today that wealthy people with no driving skills still drive, because all they have to do is slap it in to "auto" mode and away they go. Hell, a 13-year-old girl or 93-year-old woman can drive today's supercars. This manual-only Viper, though, will only be seen being driven by those who actually want nothing but the full DRIVING experience. Dodge (SRT), I applaud you for this.

      You have to give Chrysler credit here. Granted, some people will always be overly critical and some people are just terrible posers who do nothing but bash and flame for the sake of bashing and flaming. Having said that...here are my reasons why this is a success. 1. Its still carries the characteristics of the Viper that made the Viper...the VIPER. For one, it retains the V10. That in itself should have just about everyone doing flips. Flat out, you can't buy another sport(super) car with a V10 save the Audi R8 and its Lamborghini derived V10. At least not that I'm aware of. BMW tapped out with their V10. And both Mercedes and BMW have downsized their mills. The profile of the car stays true to the Viper DNA. Long hood and ridiculous proportions included. All its various ports and vents are functional. Unlike some Japanese sports cars (sedans) that I will not mention here. 2. They seemed to improve the Viper in the areas that made sense. As many people who swear the Viper DNA is rooted in no aided driving, the reality is the vast majority of people who can are privileged enough to drive it or own it can never take it to its limits. It required pro-level skills to truly experience what its capable of. What good is a track car that the average driver can't track? And what is the point of a track car that is so tricky, the likelihood of you wrecking the car even on the street is just about imminent? There is a reason they called this thing the widow maker. It NEEDED some kind of traction control system. Kudo's for laws designed to keep a street car on the damn street. Simply look at what GM was able to do with the ZR1 and Z06 once they introduced PTM. For once, you can drive the Z06 hard and keep it on the road at the same time. Chrysler is doing the same thing with the Viper. 3. Interior improvements are welcomed. Nothing more to say on this point. All in all, this is a damn fine car. If Chrysler prices it within reason....there will be A LOT OF PEOPLE who take notice. Especially would-be ZR1 and Z06 buyers who have issue with C6 interior. Granted Corvette loyalist are Corvette loyalist. This new Viper has a significant advantage over the C6 in the interior department. That alone will bring buyers.

      I'm a Corvette guy,.. Corvette owner. This thing is smokin hot and makes my lust for it. The Corvette hasn't been lusty in many years. Nicely Done SRT (Dodge/Fiat) - this one is out of the park.

      Obviously the 2013 Viper is a rolling work of art in my opinion, The SRT team did it's home work and has brought a Viper to compete with the ZR1 and other super cars from around the world, but what would be nice is if SRT would offer a version that was not so cost prohibitive to us normal folk. SRT could build a version that sports the 392 under the hood, offer a 6 speed auto with paddle shifters, scale down the interior a tad bit, basically build a Viper that is more in the price range of a regular Corvette. This would not remove any integrity from the GTS model, because the owner of a standard Corvette is nothing like the owner of a ZR1, the ZR1 vette owner is one who is looking for pure performance and doesn't really care about the price, whereas a standard vette owner wants the sportiness without having to totally empty their bank account to own it. It would be the same for future Viper owners, it works for Charger, Challenger, Camaro, and Mustang customers because they can chose between what they can afford and it does not destroy the integrity of the SRT/8, SS, or GT500 models.

          Except that the Challenger is an oversized, overweight pig of a car that drives like what it is: a barge.

      LOL @ all of the pitiful troll attempts in the comments. The Viper doesnt look exactly the same, but looks exactly as a Viper should, with the best bits of previous vipers and a whole lot of new eye candy all in a sensual package. It has a great interior improvement, is lighter, more powerful, hasnt castrated itself to seem more eco friendly, still comes with a 6 speed manual as the only transmission, has all 8.4 liters and 10 cylinders, and has a killer power to weight ratio. Though I must say, after seeing the ALMS version in the gallery, the stock one looks a little tame. Bring us the ACR!!!

      Ok, the bezels surrounding the two middle AC vents are the best I've seen in a long time. Must make more money so can play with them. To self: "STOP IT! Stop ogling these Viper pics on Autoblog! Over and Over! Must...get...back...to....work..."
