The 1933 MG J2 Supercharged is a thrilling example of pre-war British roadster design. Equipped with a 1.0-liter, supercharged inline-four engine, the J2 could reach speeds of up to 80 mph, a notable achievement for its small size. The J2 Supercharged was a precursor to MG's success in motorsport, with many owners using it for competitive racing.
