The 2013 SRT Viper debuted this morning at the New York Auto Show, marking the return of the awesome American supercar after a three-year hiatus. The reveal was no secret, but after SRT CEO Ralph Gilles he announced the Viper’s two trim lines, he dropped a big surprise: The Viper GTS-R will join this year’s ALMS grid. Hit the jump for all the details.
Across the front end, it wears a similar shape to previous models, with a wide, low, clamshell-style hood featuring an intake and two heat extraction ports facing the windshield. The new front fascia also sports LED headlights along with a darkened grille wearing the familiar crosshairs. The chassis is a whopping 50% stiffer, and it will be rolling on massive shoes–355s in back and 295s up front. Everything tips the scales at 3,297lbs.
The cockpit features race-style seats, supplied by the same sources as corporate cousins Ferrari, which allow more leg room and seat adjustment than previous Vipers. The trick seven-inch digital gauge cluster features a speedo on the left, a fuel gauge/temperature combo gauge on the right, and a massive tachometer mounted in the middle. The center section of the tach includes a driver information center with a ton of customizable options, and most importantly, a shift light which incorporates the new Viper logo.
The center stack includes a massive 8.4-inch touch screen which controls the HVAC, stereo, navigation and special SRT gauges, including quarter-mile and other performance-oriented clocks. Buyers opting for the GTS package will get steering wheel controls for the dual-mode adjustable suspension system. All models will feature traction, launch and cruise control.
Finally, while rumors indicated the 2013 SRT Viper would feature a larger V10, SRT has stuck with the same 8.4L displacement found in the 2010 model. But the engine has been tuned to offer 40 more ponies–for a total of 640hp and 600lb-ft of torque–and thanks to new lightweight components, it weighs 28 pounds less than the previous mill. That’s enough to make this V10 the most powerful naturally aspirated engine in the world. When combined with the Viper’s new lightweight architecture, it translates to a power-to-weight ratio of just 4.91 pounds per horsepower, placing it just south of stratospheric supercars like the Bugatti Veyron and the crispy new Ferrari F12.
