MG Midget III gallery (1966–1974)
The third generation featured a spirited 1.3-liter engine from the Mini Cooper S and a permanently mounted folding soft top.
Launched in the autumn of 1966, the third-generation MG Midget (Mk III) became the most enduring and commercially successful iteration of the classic line. The highlight of this generation was the installation of the 1275 cc BMC A-Series four-cylinder engine, derived directly from the Mini Cooper S, tuned to deliver 65 horsepower and significantly improved torque across the rev range. The Mk III also addressed a major usability drawback of previous cars by introducing a permanently attached folding convertible top mechanism that could be raised or stowed quickly without dismantling. Over its eight-year production span, the Mk III underwent multiple cosmetic revisions. A 1969 facelift introduced a blackened front grille, revised taillights, and black sill panels. In late 1971 for the 1972 model year, squared-off rear wheel arches were replaced by graceful rounded openings, accommodating wider Rostyle or wire wheels. By early 1974, large rubber overriders were fitted to meet tightening United States impact standards. The Mk III achieved broad popularity throughout the UK, Europe, and the vital North American export arena.
