In August 1966, Volvo presented a new 4-door car called the Volvo 144. It represented the start of an entirely new car series which, until 1974, accounted for Volvo's volume models.
In 1956, a prototype of a new passenger car from Volvo was presented. The car became known as the Amazon in Sweden and the 121 and 122S on the export markets. The designation 122S was used for a version with a more powerful engine.
