The Fiat 510 is a 4-door sedan / 4-door cabriolet from Fiat, built from 1920 to 1925, the vintage years, when coachbuilders still shaped most of what was sold. Under the bonnet: straight-6 3446 .
The story
The Fiat 510 is a passenger car produced by Fiat between 1920 and 1925. It was of a similar design than the smaller 501 and 505 models. Starting from 1920, a sports version 510 S with a more powerful engine and shorter chassis was made. Around 14,000 examples were produced.
What is underneath
Power comes from straight-6 3446 . It weighs 1550 kg. It shifts through a 4-speed manual. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. The wheelbase is 340 cm / 310 cm (510 S). These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Its place in the line
Its family tree is legible: it took over from the Fiat Tipo 7; its successor was the Fiat 512. Its contemporaries in the catalogue — the Panhard & Levassor type X 26 coupé-chauffeur, the Panhard & Levassor Type X 29 torpedo, the Mazda Mazda — show what else the money bought that year. Nearby in the Fiat catalogue sit the FIAT 702 and the Fiat 1.
What it costs now
MotorJury scores cars on the United States complaint and recall record, and the Fiat 510 has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
