In 1959 the MP Midget was introduced - updated with such features as a steering wheel, doors, and seating for two. The engine was an air-cooled 2-stroke design of 305 cc which produced 12 hp (9 kW). Subsequent revisions to the MP design were made, resulting in the model MP4 (which featured a larger cargo bed than the original model) and finally the MP5 (which introduced automatic oil mixing for the 2 stroke engine) which remained in production until 1972.
