The Ford Mustang debuted in April 1964 as a sporty, youthful car based on the Ford Falcon compact car’s low-cost mechanicals. The Mustang was an instant hit, inspiring a whole class of “pony car” rivals, including the 1967 Chevrolet Camaro and 1970 Dodge Challenger. The Ford Mustang could be anything in 1969, from a stylish six-cylinder coupe to a high-powered Boss 429 fastback with a NASCAR-ready V-8 engine crammed under its scooped hood. The Mustang’s ongoing success can be attributed to its capacity to be whatever you want it to be. Today’s Mustang coupe and convertible, which were last revised for the 2015 model year, continue the original’s design cues, with long-hood, short-deck style, a smallish backseat, and rear-wheel drive.
