The Fiat 126 is a city car manufactured and marketed by Fiat from 1972 until 2000 over a single generation. It has a rear-engine design and seats four passengers. Introduced by Fiat in October 1972 at the Turin Auto Show, the 126 replaced the Fiat 500, using major elements from its design. A subsequent iteration, marketed as the 126 Bis, used a horizontally oriented, water-cooled engine, and featured a rear hatchback with additional cargo space.
