1937 Maserati Siluro 4CM Carenato

The Maserati Siluro 4CM Carenato was a streamlined land speed record car built in 1937 by Carrozzeria Viotti. Designed by Mario Revelli di Beaumont and Giuseppe Furmanik, it had a radical torpedo-shaped body aimed at reducing aerodynamic drag as much as possible. The car was based on Maserati’s 4CM racing platform and powered by a supercharged 4-cylinder engine that produced 200 horsepower at 7,000 rpm—an impressive output for the era.

On June 2–3, 1937, Furmanik drove the Siluro on the Firenze-Mare motorway in Italy and set a new land speed record in its engine class (1100 to 1500 cc). Using a flying start, he achieved an average speed of 237.568 km/h. The Siluro demonstrated the potential of aerodynamic design and engineering precision in pursuit of high-speed performance during the pre-war era.
