Fiat's upper middle class car in the later 1920s was also designated as the Fiat 520, but was smaller and more modestly powered than its earlier namesake.

During the early decades of the 20th century European automakers, once steering wheels had replaced centrally positioned steering tillers, tended to place the driver and his steering wheel on the right side of the car regardless of any local regulations or conventions concerning which side of the road cars should be driven. By the 1920s, as the number of wheeled vehicles on the roads increased, clearer consensus had become necessary in the more populous parts of Italy about the need for everyone to drive along the right side of the road. The 1927 Fiat 520 was one of the first cars, presumably in recognition of this trend, to place the steering wheel on the left side of the car.

The 520 was replaced by the Fiat 521 in 1928, although the 520 appears to have continued in production until 1929, by when more than 20,000 six-cylinder Fiat 520s had been produced.
