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 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.
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.
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.
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.
