History
The engine was a pair of Straight-twin engines, coupled to create a Straight-four. The timing was a new for Fiat overhead camshaft, with four valves per cylinder, each with twin spark plugs. The majority of the engine was made almost entirely of brass. The ladder chassis was steel, however the body was entirely aluminum. The car did not have front brakes, only drum brakes at the rear. The car was successful in American racing, with David Bruce-Brown finishing third in the First Indianapolis 500. In 1912 Teddy Tetzlaff won at the Santa Monica Circuit. However its most prestigious win is the 1912 American Grand Prize. After the initial 4 cars were built, there were enough spare parts retained by Fiat for a fifth unit to be built in Turin in 1970.[1][2][3][4]
