The FIAT 4 HP, sometimes called the 3 ½ CV, was the first model of car produced by FIAT. Eight examples were produced in its first year (1899) and total of 24 between 1899 and 1900. The car had a water cooled 0.7-liter (679 cc) 2-cylinder, rear-mounted engine producing 4.2 horsepower at 800 rpm, mounted to a three-speed gearbox. (No reverse gear was included.) With this tiny engine the car could achieve top speed of 35km/h. Despite having such a small engine, the car used fuel 8L/100 km.
This first Fiat was based on work of Ceirano GB & C (car producer) called Ceirano Welleyes. The 3 ½ had coachwork by Marcello Alessio from Turin. Couple of the First Fiats have survived; one is in Automobile Museum of Turin, and the other one in the Ford Museum in Dearborn, Michigan in the USA.
The 'Fiat 3 ½ HP sometimes also called 'Fiat 4 HP, was the first model of vehicle built by the then nascent Italian factory in Turin Fiat.

In the early 90s, in fact, the engineer from Verona Enrico Bernardi created and a small gasoline tricycle, hitherto regarded as the first Italian car, whose production was initiated by Miari & Giusti in 1894.
L '11 July 1899, by the will of a dozen Piedmontese aristocrats who shared a passion for motor racing, was established in Turin Fiat that at the end of that year, began the production of the "3 ½ HP.
This first model is derived from "Welleyes', a car designed by Ing. Aristide Faccioli is handmade by "Ceirano GB & C", acquired by nascent FIAT.
