Fiat 16-20 HP

The Fiat 16-20 HP was a four-cylinder touring car that the Italian maker Fiat introduced in 1903. It was built in four series. The first, in 1903, had a wheelbase of 2,120 millimetres and a 4,179 cc engine rated at 20 PS, and 100 were made. In 1904 it became the 16-24 HP, with a longer wheelbase of 2,585 millimetres and 24 PS from the same engine, and 130 were made. The third series of 1905 went back to the 16-20 HP name on a still longer wheelbase of 2,853 millimetres, with 171 built, and the fourth series of 1906 received a larger 4,503 cc engine, with 290 built. Across the four series the wheelbase grew by about 730 millimetres and the engine by about 320 cc, while the production run named by the source came to 691 cars.
