The Ford Shelby GT350 was first released in 1965 as a street-legal track car with a powerful 4.7-liter, 306-horsepower engine. It received upgrades in 1966 but went largely untouched until 2014 when Ford debuted a new performance version, the 2016 Shelby GT350, with a 5.2-liter V-8 engine producing over 500 horsepower along with modern features like multiple driving modes and improved suspension.
