Introduced in September 1970, the 1971 Mustang was green-lighted by Ford's new president, Semon "Bunkie" Knudsen, formerly of General Motors.
Again, the revised model grew in size, gaining 3 inches in width in order to accommodate Ford's big block 429 cu in (7.0 L) V8 without need for an extensive suspension redesign.

As before there were three body styles offered: Hardtop (available in base or Grande trim), SportsRoof (available in base or Mach 1 trim), and convertible (no specific trim packages available).
