The most popular British-made car ever, it was superseded by the New MINI, which was launched in April 2001. The original is considered an icon of the 1960s, and its space-saving front-wheel-drive layout (that allowed 80% of the area of the car's floorpan to be used for passengers and luggage) influenced a generation of car-makers. The vehicle is in some ways considered the British equivalent to its German contemporary, the Volkswagen Beetle, which enjoyed similar popularity in North America.

This distinctive two-door car was designed for BMC by Sir Alec Issigonis. It was manufactured at the Longbridge and Cowley plants in the United Kingdom, the Victoria Park / Zetland British Motor Corporation (Australia) factory in Sydney Australia, and later also in Spain (Authi), Belgium, Chile, Italy, Portugal, South Africa, Uruguay, Venezuela and Yugoslavia.

The Mini Mark I had three major UK updates: the Mark II, the Clubman and the Mark III. Within these was a series of variations including an estate car, a pickup truck, a van and the Mini Moke — a jeep-like buggy. The Mini Cooper and Cooper "S" were sportier versions that were successful as rally cars, winning the Monte Carlo Rally three times.

Minis were marketed under the Austin and Morris names until Mini became a marque in its own right in 1969.

The Mini is today owned by the prestigious BMW Motor Group.
