The World's Fastest Production Car Was a Tricycle - Apparently.
In 1949, a tricycle called the "Wimpole" was built by engineer Rex Maney, and it holds the Guinness World Record for the fastest production tricycle. The Wimpole reached a speed of 118.97 mph (191.66 km/h) on the Salt Lake City salt flats. The tricycle's speed was verified by officials on April 2, 1949, and it remains an unusual record to this day.
