The Vespa has evolved from a single model motor scooter manufactured in 1946 by Piaggio & Co. S.p.A. of Pontedera, Italy to a full line of scooters and one of seven companies today owned by Piaggio. From their inception, Vespa scooters have been known for their painted, pressed steel unibody which combines a complete cowling for the engine (enclosing the engine mechanism and concealing dirt or grease), a flat floorboard (providing foot protection), and a prominent front fairing (providing wind protection) into a structural unit. Post World War II Italy, in light of its agreement to cessation of war activities with the Allies, had its aircraft industry severely restricted in both capability and capacity. Piaggio emerged from the conflict with its Pontedera fighter plane plant demolished by bombing. Italy's crippled economy and the disastrous state of the roads did not assist in the re-development of the automobile markets. Enrico Piaggio, the son of Piaggio's founder Rinaldo Piaggio, decided to leave the aeronautical field in order to address Italy's urgent need for a modern and affordable mode of transportation for the masses. In 1944, Piaggio engineers Renzo Spolti and Vittorio Casini designed a motorcycle with bodywork fully enclosing the drivetrain and forming a tall splash guard at the front. In addition to the bodywork, the design included handlebar-mounted controls, forced air cooling, wheels of small diameter, and a tall central section that had to be straddled. Officially known as the MP5 ("Moto Piaggio no. 5"), the prototype was nicknamed "Paperino" (either "duckling" or "Donald Duck" in Italian).[2] Piaggio was displeased with the MP5, especially the tall central section. He contracted aeronautical engineer Corradino D'Ascanio, to redesign the scooter.
