Description
The MG M-type Midget Supercharged was a competition-focused evolution of the original M-type Midget, introduced at the end of the 1920s. Based on MG’s first true production sports car, the supercharged version reflected the company’s early commitment to lightweight performance and motorsport development.
The standard M-type Midget, launched in 1929, used a compact chassis derived from the Morris Minor and featured a small-displacement four-cylinder engine. In supercharged form, this engine was fitted with a Roots-type supercharger, significantly increasing output over the naturally aspirated version. While the base engine produced modest power, the addition of forced induction transformed the car’s performance, making it competitive in small-capacity racing classes.
The supercharged M-type retained its lightweight construction, which was central to its success. The chassis was simple and narrow, with a ladder-frame structure and minimal bodywork. Most examples were configured as two-seat open sports cars, with cycle wings and a low, purposeful stance. The combination of low weight and increased power allowed impressive performance relative to engine size.
The engine was typically a 847 cc four-cylinder unit with overhead camshaft design, which was advanced for its time in this class. With supercharging, output increased substantially, enabling higher top speeds and stronger acceleration. A manual gearbox transmitted power to the rear wheels, and the car’s compact dimensions contributed to agile handling.
The MG M-type Midget Supercharged became popular in club racing and record attempts. It helped establish MG’s reputation as a manufacturer capable of producing affordable sports cars with genuine competition potential. The car’s success in trials and racing events during the early 1930s strengthened the brand’s sporting image.
Inside, the cockpit was minimal and functional. Instruments were basic but clearly laid out, reflecting the car’s competition orientation. Comfort was secondary to weight reduction and mechanical simplicity.
Today, the MG M-type Midget Supercharged is regarded as an important early chapter in MG’s sporting history. Surviving examples are rare and highly valued, particularly those with documented competition history. As a historical vehicle, it represents MG’s early embrace of supercharging technology and its determination to compete successfully in small-capacity racing, laying the groundwork for the brand’s later sporting achievements.
