'Mustang' was a name given to Ford's new 'Personal Car' There is some debate as to whether 'Mustang' was inspired by wild horses or by the World War Two P51 Mustang fighter plane. There are many claims to the design of the Mustang, including the sketches of Phil Clark, who DID do the Mustang logo and possibly gave it the name 'Mustang'. John Najjar designed a mid-engined concept car, the Mustang 1, and credits Phil Clark with contributing to this. The 4-seater production prototype was developed under Donald N. Frey and attributed to Joe Oros and L. David Ash. The final version raided the parts bin for components from Ford Fairlane and Ford Falcon, and was launched at the 1964 New York Worlds Fair. The launch car was given a 260cu (4,260cc) in V8 engine, or a 170cu in (2,785cc) 6-cylinder. In the fall of 1964 the 1965 Mustangs were given a 289cu in (4785cc) V8, rear reversing lamps. Also for 1965 a new Fastback body was added to the Coupe and convertible, and a Carroll Shelby GT350 version was also marketed. For 1966 a GT version with grille mounted spotlamps was announced and a horizontal bar was given to the grille. Mustang bodies were revised for 1967 growing longer and taller.
