Renault 4L 1969

The Renault 4, or R4 in short (and 4L, pronounced "Quatrelle", in French), is an economy car built by the French company Renault from 1961 to 1994. Although the Renault 4 was first marketed as a short estate or wagon, its minimal rear overhang, and its top-hinged, single-piece tail-gate made it the world's first mass-produced hatchback car, as well as the first time Renault had used a front-wheel-drive layout in a family car.[nb 1] A bare-bones, entry-level Renault 3, or R3 was also offered in 1961/1962.

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 However, by the late 1950s, the 2CV was becoming outdated.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 70 km/h (43 mph). Its air-cooled two-cylinder engine was reliable and economical but noisy and offered poor performance. The 2CV's suspension gave it an excellent ride and good grip and handling but was mechanically complex with many moving parts that required regular maintenance and lubrication at intervals as low as every 1000 miles (1600km). With its roots in the 1930s, the 2CV's styling was also outdated and, with its separate wing/fenders, had a relatively narrow and cramped body for its overall footprint. While the Citroën had been designed during the Great Depression when money was tight and living standards were relatively low, by the 1960s the French economy was growing and people would be able to afford a more modern, refined, and less utilitarian small car.

In early 1956, Renault Chairman Pierre Dreyfus launched this new project: designing a new model to replace the rear engined 4CV and compete against the Citroën 2CV that would become an everyman's car, capable of satisfying the needs of most consumers. It would be a family car, a woman's car, a farmer's car, or a city car.

The Renault 4 shared many design traits with the older Citroën 2CV to allow it to fulfill the same role as a versatile utility car, especially for people in rural France and other parts of the world with poor roads. It had a large structural platform with a separate body. It had front-wheel drive, long-travel fully independent suspension, and Rack and pinion steering. It had a simple body with minimal equipment, a large space for cargo or luggage, and 'deckchair' seats which could be easily removed. However, the Renault 4 updated this basic concept with a larger four-cylinder water-cooled engine with a sealed cooling system offering much better refinement and performance than the contemporary 2CV, with a top speed of over 104 km/h (65 mph). The suspension consisted of torsion bars which required no regular maintenance. The boxy full-width body offered more space for both passengers and luggage than the similar-sized 2CV and the car boasted an early hatchback body for greater practicality.

Renault launched the Renault 3 and the Renault 4 simultaneously in July 1961. The cars shared the same body and most mechanical components, but the R3 was powered by a 603 cc version of the engine while the R4 featured a 747 cc engine. This placed the R3 in the 3CV taxation class while the R4 was in the 4CV class. Maximum power output was rated by Renault as 22.5 hp (16.5 kW) for the R3, and 26.5 or 32 hp (19.5 or 23.5 kW) for the R4, depending on price level and the type of carburettor fitted. Initially the base versions of the R3 and R4 came with a thick C-pillar behind each of the rear doors. Quarter glass was a 400 franc option for the basic R4. The extra visibility increased the weight of the vehicle, but these windows soon became standard for all R4s.
