Fiat needed to re-new the middle size sedan and Dante Giacosa began to test three different kind of mechanical layout: front engine and rear wheels-traction, front-engine and front wheels traction, rear engine and rear wheels traction. In the end, they decided on the more classical scheme and they produced the solution with front engine and rear wheels traction. The car was produced in Italy from 1966 till 1974, but in many foreign countries for many other years and with many different brands in more than 15 million pieces.
