The Fiat 503 is a 4-door sedan / 4-door cabriolet from Fiat, built from 1926 to 1927, the vintage years, when coachbuilders still shaped most of what was sold. Under the bonnet: 1460 .
How it came about
The Fiat 503 is a car produced by Fiat between 1926 and 1927. The 503 was based on the Fiat 501, with modified suspension and brakes. It used the 501's 1.5-liter engine, producing 27 PS (20 kW). The company produced 42,000 examples of the 503.
The hardware
Power comes from 1460 . It weighs 1100 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 275 cm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Family and rivals
Its family tree is legible: it took over from the Fiat 501; its successor was the Fiat 514. Its contemporaries in the catalogue — the Mercedes-Benz W03, the Delage Type 15 S 8, the Bentley Speed Six — show what else the money bought that year. Its Fiat stablemates include the FIAT 702 and the Fiat 1.
What it costs now
There is no federal ownership record for the Fiat 503 — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
