Numbers first, because with the Fiat S74 they are the story: 14137.2 cc Inline 4, 180 bhp at 1,800 rpm. Fiat built from 1911 to 1912, as the assembly line was turning motoring into an industry. Its designer of record is Gaetano Stefanini / Giuseppe Coda.
Under the skin
Under the skin sits 14137.2 cc Inline 4; it is rated at 180 bhp at 1,800 rpm. Kerb weight is 2718 kg. Power-to-weight lands near 66 horsepower per tonne, which is unhurried — enough for the job, not for the bragging. The gearbox is 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 2718 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Where it sits in Fiat's history is not in doubt: the Fiat S61 came before it; the Fiat S76 Record followed it. On a showroom list of its day it stood against the Bugatti Type 18. Nearby in the Fiat catalogue sit the FIAT 702 and the Fiat 1.
The money
MotorJury scores cars on the United States complaint and recall record, and the Fiat S74 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.
