The Fiat 522 is a passenger car produced by Fiat between 1931 and 1933. The 522 was derived from predecessor models, now with a new chassis and the option of a shorter wheelbase.
The engine was an in-line six-cylinder engine of 2,516 cc for which 52 bhp (39 kW) of output was claimed. The car also featured a four-speed all-syncromesh gear box, which set this Fiat ahead of its time.
The 522 was the first model to feature Fiat's subsequently familiar rectangular logo: the badge used here employed gold lettering on a red background.
Almost 6,000 examples of the 522 were produced. A Fiat 522 CSS was also offered: in this version, the car had a higher compression ratio and twin carburetters.
