01 / THE STORY
History & context
The OM 665 S MM Cabriolet Touring (1930) was coachbuilt by Touring and designed by Giuseppe Seregni. Developed during the interwar period, this model represents the collaboration between OM (Officine Meccaniche) and notable coachbuilders, reflecting the trends in automotive design and craftsmanship of the era. The design process emphasized aerodynamic proportions and lightweight construction methods, which were integral to performance in the Mille Miglia races.
Mechanically, the OM 665 S MM featured a robust configuration, including a chassis that supported dynamic handling and stability at high speeds. Powered by a V8 engine, it was engineered for efficient power delivery, contributing to its competitive edge. The suspension system was meticulously designed to enhance ride comfort and road handling, aligning with the expectations of both the racing community and luxury car buyers of the time.
Production data indicates that the OM 665 S MM Cabriolet Touring was produced in limited numbers, reflecting the bespoke nature of the coachbuilding process. Surviving examples are recorded, highlighting the craftsmanship and attention to detail characteristic of Touring’s work. These vehicles were often showcased at prestigious automotive exhibitions, illustrating their significance within the context of automotive history. Documentation indicates that the combination of OM’s engineering prowess and Touring’s design innovation resulted in a model that remains of interest to automotive historians and researchers.
Surviving examples are recorded in private collections and institutional archives, providing reference for researchers of postwar coachbuilding.
