Fiat 4HP

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 26 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 35 kilometres per hour (22 mph). Despite having such a small engine, the car used fuel 8 litres per 100 kilometres (35 mpg-imp; 29 mpg-US).

This first Fiat was based on work of Ceirano GB & C (car producer) called Ceirano Welleyes. The 3 ½ had coachwork made by Marcello Alessio from Turin. At least four of the first Fiats have survived. One is in Automobile Museum of Turin, one in Centro Storico Fiat, one in National Motor Museum in the United Kingdom and one in the Ford Museum in Dearborn in the USA
