The Fiat S61 is the fifth Grand Prix car built by Fiat.

History

The engine was a pair of Straight-twin engines, fit into a Straight-four. The timing was a new for Fiat Overhead camshaft, with 4 valves per cylinder, each with 2 Spark plug s. 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, and drum brakes in the rear. The car was extremely successful in America , with David Bruce-Brown finishing third in the First Indianapolis 500. In 1912 Ted 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.
