Used 2017 Dodge Viper Coupe Trims Comparison

Standard equipment on the base SRT includes 18-inch front and 19-inch rear wheels with high-performance tires, keyless ignition and remote entry, manually adjustable seats, a tilt-only leather-wrapped steering wheel, power-adjustable pedals, an auto-dimming rearview mirror, a rearview camera, automatic air-conditioning, an 8.4-inch touchscreen (Dodge's Uconnect infotainment system), a navigation system, SRT performance apps, Bluetooth phone and audio connectivity and a 12-speaker Harman Kardon surround-sound audio system with satellite radio and a USB port.

Move up the ladder to the GTC and you'll get a racier hood, Brembo brakes, a five-mode stability control system, a taller sixth-gear ratio, driver-adjustable dampers, a six-way power driver seat and leather seats with simulated suede inserts. The GTS goes further with upgraded leather upholstery and interior trim and an 18-speaker premium Harman Kardon audio system.

Then there's the race-focused ACR Viper. It gets lighter wheels (19-inch wheels in front), less sound insulation, lighter-weight carpeting and less of it, manual adjustable seats, a minimal three-speaker stereo, carbon-fiber aerodynamic elements, more aggressive summer tires, six-piston brake calipers, carbon-ceramic brake rotors, a stiffer suspension with 10 manually adjustable damper settings for compression and rebound, and manually adjustable spring rates.

Many of the premium and ACR features are available on lower trim levels for an extra cost. Other options include numerous carbon-fiber exterior and interior treatments. The TA 1.0 and TA 2.0 packages (with specially tuned suspension) and the Extreme Aero package for the GTC and ACR trims add a large, dual-element rear wing and a front splitter with a removable extension, a carbon-fiber rear diffuser and even more aggressive aerodynamic tweaks.

A handful of special editions are also available for 2017, including the Viper 1:28 Edition ACR, Viper GTS-R Commemorative Edition, Viper Snakeskin Edition, Viper VooDoo II Edition and Viper Dodge Dealer Edition. Each has a specific permutation of features and/or special paint and interior and exterior trim details.

Every 2017 Dodge Viper is powered by an 8.4-liter V10 that produces 645 hp and 600 pound-feet of torque. Power is sent to the rear wheels through a six-speed manual, which is the only available transmission. At the Edmunds test track, a Viper GT went from zero to 60 mph in just 3.6 seconds.

EPA estimated fuel economy for the 2017 Dodge Viper is 14 mpg combined (12 city/19 highway), which is poor, even for this class of high-performance cars. During our yearlong test of a Dodge Viper GT, we found that it can easily clear its city/highway estimates if you use a light foot, but if you can't resist the urge to engage the loud pedal, you'll easily get single-digit mileage.
