Track tested at more than 200 mph, the incredibly powerful 2013 Shelby GT500 which boasts the most powerful production 5.8-liter supercharged V8 engine on earth, has been especially designed to make the discerning auto enthusiasts part of the Shelby legend. However, it’s interesting to note that Shelby Mustang is a high performance variant of the Ford Mustang which was originally built by Shelby American from year 1965 through 1970. Described to be the fastest, most powerful Mustang ever with 662 horsepower, this 3,852-pound ride with advanced aerodynamic design and AdvanceTrac Electronic Stability Control is able to accelerate to a top track speed of more than 200 mph. Whereas, the muscular, sculptured exterior design of the 2014 Mustang is a modern interpretation of classic Mustang heritage, and Ford designers worked to give even more "muscle" to this iconic car.
