The Ford Mustang has been an iconic symbol of American muscle since its introduction in 1964. Among the myriad variants, the Shelby models stand out as some of the most revered, embodying speed, performance, and a spirit of innovation. This article explores the evolution of the Ford Mustang Shelby cars, detailing the significant models and trim levels that have emerged over the years.
1965-1966: The Birth of a Legend
1965 Shelby GT350
The saga of the Ford Mustang Shelby began in 1965 when Carroll Shelby, a former race car driver and founder of the Shelby American company, collaborated with Ford to create the GT350. Designed as a race-ready version of the Ford Mustang, the GT350 featured a 289-cubic inch V8 engine that produced 306 horsepower. The car was lightweight, thanks to modifications like a fiberglass hood and a minimalist approach to the interior. Shelby’s involvement transformed the Mustang from a simple pony car into a racetrack contender.
1966 Shelby GT350
In its second year, the 1966 Shelby GT350 remained largely unchanged but saw an increase in production with more than 2,300 units produced. This model continued to feature performance enhancements like power disc brakes and an upgraded suspension.
1967-1968: Expansion and Refinement
1967 Shelby GT500
In 1967, Shelby introduced the GT500, which stood as a more powerful alternative to the GT350. This model was equipped with a 428-cubic inch Cobra Jet V8, yielding 355 horsepower. The GT500 would further cement the Shelby brand’s focus on performance with its distinctive cobra insignia and aggressive styling, including functional air scoops.
1968 Shelby GT350 and GT500KR
The 1968 models featured more refined styling and added performance. The GT350 received several upgrades, including a new 302-cubic inch V8 that improved horsepower. The more powerful GT500KR (“King of the Road”) variant debuted with the potent 428 cubic inch V8, bumping performance figures to 400 horsepower. Shelby’s commitment to racing continued to shape these cars significantly.
1969-1970: Performance Meets Aesthetic Change
1969 Shelby GT350, GT500, and GT500KR
In 1969, Shelby began to focus on adapting to the changing automotive market, leading to a complete redesign of the Mustang platform. The new GT350 was available with a 351-cubic inch V8 engine, a shift from its predecessors. The GT500 now featured a new “Cobra Jet” engine, offering substantial power.
The 1970 models saw refinement in styling, but production ceased after this year for the Shelby variants due to increasing competition and safety regulations.
