The Fiat 525 is a series of cars introduced by Fiat in 1928. Powered by a 3.8L inline six engine, the 525 was built in three body styles (saloon, spider, and cabriolet), and featured three main variants, the 525N, which was an updated base model, the 525S, and the 525SS which were more power and sporty models. The Fiat 525 family of cars was in production until 1931.
