The Fiat 126 is a four-passenger, rear-engine, city car manufactured and marketed by Fiat over a twenty-eight year production run from 1972 until 2000, over a single generation. 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.

The Turin Motor Show was an auto show held annually in Turin, Italy. The first official show took place between 21 and 24 April 1900, at the Castle of Valentino, becoming a permanent fixture in Turin from 1938 having shared it with Milan and Rome until that time. From 1972, the show was held biannually and in 1984, it moved into Fiat's shuttered Lingotto factory.
