Autobianchi was an Italian automobile manufacturer, created jointly by Bianchi, Pirelli and Fiat in 1955. Autobianchi produced only a handful of models during its lifetime, which were almost exclusively small cars, with the biggest being the short-lived Autobianchi A111, a small family car. Autobianchis were priced higher than Fiat models of similar size and the brand was used by Fiat to test new and innovative concepts which later found their way into mainstream Fiat vehicles; these concepts included fibreglass bodies and front-wheel drive.
The most famous Autobianchi models include the A112 released in 1969, a small hatchback very popular in Italy for racing, and which ceased production in 1986; as well as the Y10, which was the first car to use Fiat's new FIRE ( Fully Integrated Robotised Engine). The Primula was the car with which Fiat introduced the particular front-wheel drive arrangement of engine, transmission and differential (final drive) that has become prevalent in its cars today.
Autobianchi was bought by the Fiat group and integrated into the operations of Lancia. The marque survived in Italy until the end of the Y10's production in 1995, but became extinct elsewhere when the model was rebranded as a Lancia in 1989.
