When Peugeot acquired Citroën and formed PSA, the group's collaboration with Renault was reduced, although established joint production projects were maintained. Prior its merging with Peugeot, Citroën sold to Renault the truck and bus manufacturer Berliet in December 1974, merging it with its subsidiary Saviem in 1978 to create Renault Véhicules Industriels, which became the only French manufacturer of heavy commercial vehicles. In 1976, Renault reorganised the company into four business areas: automobiles (for car and light commercial vehicles or LCVs), finance and services, commercial vehicles (coaches and trucks over 2.5 tons GVW), and minor operations under an industrial enterprises division (farm machinery, plastics, foundry, etc.). In 1980, Renault produced 2,053,677 cars and LCVs. The cars at the time were the Renault 4, 5, 6, 7, 12, 14, 16, 18, 20, and 30; the LCVs were the 4, 5, and 12 Société and the Estafette. The company added 54,086 buses/coaches and trucks.
