New for 2015 is the Viper GT model that builds off the entry-level Viper by adding the driver-selectable suspension system, featuring Bilstein DampTronic Select shock absorbers with street and track settings, a five-mode electronic stability control system, and a unique interior with standard Alcantara and Nappa leather seats available in black, Demonic Red or Sepia, with accent stitching for the customer who wants a true Grand Touring performance machine. 
The new Dodge Viper GT model will be priced between the Viper and Viper GTS models. Final pricing will be announced at a later date.

The heart and soul of the 2015 Dodge Viper SRT is its venerable, handcrafted, all-aluminum 8.4-liter, mid-front V-10 overhead-valve engine, featuring an ultra-high-flow, lightweight composite intake manifold; high-strength forged pistons; sodium-filled exhaust valves; exhaust system catalysts to ease backpressure and an aluminum flywheel that reduces reciprocating losses.
 
Engine calibration and transmission refinements for 2015 raise the horsepower rating for the SRT-engineered V-10 to 645 horsepower, while fuel economy increases one mile per gallon (mpg) on the highway to 20 mpg. Engine torque remains at 600 lb.-ft. – the most torque of any naturally aspirated sports-car engine in the world.

Approximately 25 pounds have been shaved fromthe fully dressed engine compared with the previous-generation model (2010 model year).
 
The Tremec TR6060 six-speed manual transmission features close gear ratios and a final-drive ratio of 3.55. Short shifter throws make the 2015 Dodge Viper models extremely engaging to drive. Its top speed of 206 mph is achieved through 6th gear with maximum engine speed (redline) at 6,200 rpm.
 
For 2015, a revised sixth gear ratio has been added for the Dodge Viper GT and GTS models, resulting in reduced engine noise at highway cruising speeds.

The street-legal Dodge Viper SRT TA (Time Attack)2.0 Special Edition is an evolution of the successful 2014 TA model and provides even more downforce with a new rear wing balanced with aerodynamic additions for the front of the car. The TA 2.0 is specifically built for performance enthusiast drivers who like to exercise their machines at the morethan 150 road-race courses across North America.
 
The TA 2.0 Special Edition Package builds upon the Viper’s ultra-low center of gravity, 50/50 weight distribution and largest contact patch in the production car world. The Viper TA 2.0 uses chassis parts developed specifically by the SRT Engineering chassis dynamics team to attain the most out of the race-car-like chassis and create the most confidence inspiring Viper ever. SRT Engineering developed new spring rates, dampers, sway bars and brake components, combined as a system with the new rear wing and front aero devices, to create oneof the most track-capable production cars in the world. The changes keep the Dodge Viper SRT TA 2.0 glued to the track, while the brake system is enhanced for improved balance and to resist thermal saturation during track work.
