The Peel P50 is a three-wheeled micro car originally manufactured from 1962 to 1965. It was manufactured by the Peel Engineering Company on the Isle of Man. It was listed in the 2010 Guinness Book of Records as the smallest production car ever made. It had no reverse gear but a handle at the rear that allows the very light weight car to be physically maneuvered when required.
