The Shelby GT500 Super Snake is a heavily modified variant of the Ford Mustang GT500 that differs from the base model primarily due to its more-powerful engine and additional performance components. The Super Snake's engine produces as much as 850 horsepower in the 2014 version of the vehicle.
Racer Carroll Shelby and his automotive tuning firm Shelby American have released three different generations of the Shelby Super Snake version of the Ford Mustang. The original Super Snake was not a Mustang, but a souped-up version of the AC Cobra roadster that Shelby constructed in 1966. Shelby then rebuilt a 1967 GT500 with the 427-cubic-inch V8 engine from the Le Mans-winning Ford GT40 as a prototype, but only produced one of these vehicles.
The release of the retro-styled fifth-generation GT500 led Shelby American to resurrect the Super Snake nameplate in 2008. These new Super Snakes featured engine modifications boosting output to 605 horsepower, and it had 20-inch wheels, six-piston brakes and custom exterior features. A drag-racing edition was also available that boosted the output of the engine to 800 horsepower via a twin-screw supercharger. The revised version of the GT500 released since 2008 led to subsequent upgrades to the Super Snake. The manufacturer based the final 850-horsepower iteration of the GT500-based Super Snake on the 2014 GT500 model.
