The Renault 4, also known as the 4L (pronounced "Quatrelle" in French), is a small economy car produced by the French automaker Renault between 1961 and 1994. Although the Renault 4 was marketed as a short station wagon, its minimal rear overhang, and single top-hinged rear opening made it the world's first mass-produced hatchback car, as well as the first front-wheel drive family car produced by Renault.
The car was launched at a time when several decades of economic stagnation were giving way to growing prosperity and surging car ownership in France. The first million cars were produced by 1 February 1966, less than four and a half years after launch; eventually over eight million were built, making the Renault 4 a commercial success because of the timing of its introduction and the merits of its design. In early 2020, the 33-year production run of the Renault 4 was counted as the seventeenth most long-lived single generation car in history.
The Renault 4 was Renault's response to the 1948 Citroën 2CV. Renault was able to review the advantages and disadvantages of the 2CV design. The Citroën had made motoring available to low-income people in France, and especially to farmers and other people in rural areas, for whom the car was as much a working tool as personal transport. The 2CV had been designed in the 1930s for use in the French countryside where the road network was poor - speed was not a requirement but a good ride, useful rough-terrain ability, a versatile body for load carrying, and economy and simplicity of operation were its key considerations. However, by the late 1950s, the 2CV was becoming outdated. Rural roads in France were improved and the national system of autoroutes was being developed. Agriculture was becoming more mechanized with fewer smallholdings and family farms for which the 2CV was designed. The Citroën had also proved popular with people living in towns and cities as affordable, economical transport but the 2CV's rural design brief made it less than ideal as a city car and, despite improvements, the late-1950s 2CV had a top speed of just .
