Pony car is an American car classification for affordable, compact, highly styled coupés or convertibles with a "sporty" or performance-oriented image. Common characteristics include rear-wheel drive, a long hood, a short decklid, a wide range of options to individualize each car and use of mass-produced parts shared with other models. The popularity of pony cars is largely due to the launch of the Ford Mustang in 1964.
