The 1100 had a four-speed manual gearbox and room for five people. There was also a three-speed semi-automatic gearbox that required manual shifting but used an electronically activated clutch. The 1100s transmission configuration was the same as the one introduced by Fiat on the 1964 Autobianchi Primula, in that it was transverse and axial with the engine giving the "engine on one side, transmission on the other" layout copied on almost all "hatchbacks" and front wheel drive vehicles throughout the world ever since. In France, the 1100 was very successful, achieving best-seller status, but it was less competitive in non-European export markets.
