The following was excerpted from a history of the SIMCA 1000 website.
[During the winter of 1959-1960, Fiat’s Project 122 was dropped from SIMCA’s plan after it became clear that the company’s own effort would be more suitable, this leaving Projet 950 a clear run to production. Now that the small car plan was focused around solely around Projet 950, the new car development moved forwards rapidly. By the spring of 1960, Projet 950 prototypes were in circulation, acting as mobile testbeds for varying mechanical configurations]
