STORY

The Mustang was introduced on April 17, 1964, and shown at the New York World's Fair, and Ford reports 22,000 orders on the first day. Within the first year it sold more than 400,000, with Ford counting 417,000 in its first 12 months. The Mustang II, derived from the Pinto, was introduced in September 1973 for the 1974 model year. The generation shown on December 5, 2013 for 2015 replaced the live rear axle with an independent rear suspension and was offered in right-hand drive. The seventh generation, sold as a 2024 model, uses the fourth-generation 5.0-litre Coyote V8, rated at 480 hp, or 486 hp with the active-valve exhaust, in the GT.
