Produced by Fiat from 1907 onward, inheriting a large portion of the mechanic components of the 16/20 HP model, it is a medium-powered car with a 2-block engine and a chain transmission. One of the most important features of this model is the use of a unique type of engine starting device which relies on compressed air provided by a special compressor. The 400 units of this car were built in three different wheelbases to accommodate different body types, obtaining great success also abroad.
