Confirming an earlier report, Dodge has announced that the 2015 Viper’s 8.4-liter V10 engine produces 645 horsepower – 5 horsepower more than on the 2014 model.
Torque remains unchanged at 600 lb-ft (813 Nm). Mated to a six-speed Tremec manual transmission, the engine also delivers an improved mileage rating on the highway – 20 mpg (11.8 l/100 km) versus 19 mpg (12.4 l/100 km) before.
The Dodge Viper gets a new grade for 2015, the GT, which slots in between the standard model and the GTS. It adds a driver-selectable suspension system featuring Bilstein DampTronic Select shock absorbers with street and track settings, a five-mode electronic stability control system, as well as a unique interior with standard Alcantara and Nappa leather seats available in black, Demonic Red or Sepia, with accent stitching.
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.
Also new for 2015 are two special editions, the Viper GTS Ceramic Blue Edition Package and the Viper TA 2.0 Special Edition. The former features an exclusive Ceramic Blue paint color with black stripes and five-spoke “Rattler” wheels finished exclusively in Black Vapor Chrome. Unique exterior upgrades include a GTS sill badge, Satin Black exhaust bezel, Ceramic Blue fuel filler door, orange brake calipers, carbon fiber brake ducts and rear applique.
The interior features an Alcantara wrapped headliner, door bolsters and knee blockers, as well as silver and carbon fiber accents. An exclusive carbon serialized GTS badge adorns the dashboard identifying the production number of the vehicle. Only 40 units of the Viper GTS Ceramic Blue Edition Package will be built during the 2015 model year.
As for the Viper TA 2.0 Special Edition, it is an evolution of the 2014 Viper Time Attack model, providing more downforce with a new rear wing balanced with aerodynamic additions for the front of the car. The wing increases downforce from 278 pounds (126 kg) at 150 mph to 400 pounds (181 kg) at 150 mph compared with the 2014 Viper TA. The aerodynamics package also includes new front dive planes and carbon fiber front corner splitters with extended rub strips.
The 2015 Viper TA 2.0 is available in three limited-edition colors (Competition Blue, Yorange and Venom Black), with Dodge to build 32 units of each color.
