01 / THE STORY
History & context
The OM 665 SS MM Zagato (1930) was coachbuilt by Zagato. During this period, Officine Meccaniche (OM) was known for producing vehicles that combined performance with stylistic innovation, catering to a clientele that valued both speed and aesthetics. The development of the 665 SS MM model marked a significant advancement in the brand’s offerings, emphasizing lightweight construction and aerodynamic design.
The coachbuilding process undertaken by Zagato involved meticulous attention to proportions and detailed craftsmanship, employing methods that included the use of aluminum for the body panels to reduce weight and enhance performance. The design reflected the stylistic context of the era, characterized by streamlined forms and a focus on both functionality and visual appeal.
Mechanically, the OM 665 SS MM featured a robust chassis and was designed to accommodate a V8 engine, which provided a balanced power-to-weight ratio suitable for competition and spirited driving. The suspension system was engineered for agility, enhancing the vehicle’s handling characteristics on various terrains.
Production of the OM 665 SS MM Zagato was limited, and documentation indicates that it was primarily targeted at racing events, showcasing its capabilities through several exhibitions. Surviving examples are recorded in private collections and institutional archives, providing reference for researchers of postwar coachbuilding. The model remains a notable example of the collaboration between OM and Zagato, illustrating the intersection of engineering and artistic design in early 20th-century automotive history.
