The Dodge Viper (VX I) (marketed as SRT Viper in 2013 and 2014) is the fifth and final generation of the Viper sports car. Introduced in the 2013 model year, the car was entirely redesigned and included features such as an anti-lock braking system, electronic stability control and traction control that made the car compatible to modern vehicle safety standards. The discontinuation of production of the VX I in August 2017 marked the culmination of the Viper sports car.

At a dealer conference on September 14, 2010 in Orlando, Florida, the then-Chrysler Group and Fiat CEO Sergio Marchionne was reported to have concluded his remarks by unveiling a rolling 2012 Dodge Viper prototype. There would be cars produced for the 2011 model year. In autumn of 2011, SRT executive Ralph Gilles announced that the next generation of the Viper would debut at the New York Auto Show in April 2012. At the 2013 New York International Auto Show, the all new SRT Viper GTS was unveiled along with plans to enter the car into racing as well.

As part of Chrysler's plan of turning SRT as a separate vehicle brand within Chrysler Group LLC, the SRT Viper became the brand's halo vehicle. In May 2014, the SRT brand was re-consolidated under Dodge, with former SRT CEO Ralph Gilles continuing as senior vice president of product design and also as the CEO and president of Motorsports. The car was renamed back to Dodge Viper in 2015.

SRT initially offered two versions of the Viper; the SRT Viper and the GTS. The GTS is the premium model offering more creature comforts over the base model. The most notable exterior difference between the two models is the hood. The base model has six functional hood vents while the GTS model only has two. To commemorate the return of the Viper, SRT offered a 'launch edition' package available on 150 GTS models in 2013. All of the launch edition cars were painted in Viper Blue with twin white stripes and came with a serialized dash plaque placed inside their cabins. The interior of the launch edition cars was trimmed in Black Laguna leather with contrast stitching.

The SRT Viper GTS includes leather upholstery, accented colors on the seats, doors, center console and stitching; gun metal trim on the cluster bezel, HVAC outlets, window switch bezels, shifter base, park brake bezel and the integrated passenger grab handle on the center console; Sabelt racing seats with Kevlar and fiberglass shell, carbon-fiber hood, roof, decklid and aluminum door panels, split six-spoke forged aluminum "Venom" wheels with polished face and graphite-painted pockets (standard), fully painted Hyper Black or fully painted low-gloss black finished wheels.

The SRT Viper includes cruise control and controls on the steering wheel. It also features an Alpine surround sound system with an 8.4-inch display with an optional navigation system by Garmin, Sirius-XM satellite radio, and HD radio. The gauge cluster features a four-inch reconfigurable TFT display for vehicle information as well as a "Track Mode" with a built-in track timer, "stoplight" countdown timer display, and other features. Power seats, keyless entry, and heated seats are also new options. A built-in HDD for storing music and photos was also included as standard equipment.

The optional SRT Track Package includes Pirelli P Zero Corsa tires, StopTech slotted two-piece brake rotors and lightweight wheels in Hyper Black or matte black finishes.

Dodge introduced a new GT package in 2015 to fill the gap between the base Viper and the GTS model. The GT package included the two-mode, driver-adjustable suspension and five-mode electronic stability control system from the GTS, along with Nappa leather seats with Alcantara accents and contrast stitching.
