The history of the Citroën SM
The Citroën SM was born in 1970 from André Citroën's desire to create a revolutionary grand tourer. Developed in collaboration with Maserati, which Citroën had taken control of, the SM combined French expertise in hydropneumatic suspension with the Italian tradition of high-performance engines. The MICHELIN prototype represented an experimental evolution of this already avant-garde model.
This coupe saloon stood out for its futuristic lines designed by Robert Opron and its revolutionary technical innovations: automatic power steering, directional headlights, and of course the famous Citroën hydropneumatic suspension. The MICHELIN prototype pushed these innovations even further, exploring new technical possibilities.
Despite critical acclaim and international recognition, including the title of "Car of the Year" in 1971, the SM remained a confidential model with only 12,920 examples produced between 1970 and 1975, making each version, including the prototypes, exceptional pieces .
Citroën: innovation at the heart of its DNA
In the 1970s, Citroën embodied French technological audacity. Under the leadership of André Citroën and his successors, the brand with the chevrons didn't hesitate to shake up automotive conventions. The SM was a perfect fit for this philosophy of innovation, succeeding revolutionary models like the Traction Avant and the DS.
The SM era was Citroën's golden age of research and development . The French brand collaborated closely with technology partners like Michelin, exploring new avenues in tires, suspension, and aerodynamics. This prosperous, though economically challenging, period gave birth to the brand's most iconic models.
Citroën's philosophy at this time was to "create the automobile of tomorrow today", an approach that is perfectly reflected in the development of experimental prototypes such as the SM Proto MICHELIN .
The anecdote of the rolling laboratory
The Citroën SM Proto MICHELIN hid many secrets within its futuristic flanks. This prototype actually served as a rolling laboratory for testing the most advanced tire innovations of the time. Michelin, a long-standing partner of Citroën since the early days of the automobile, used this modified SM to experiment with new rubber compounds and revolutionary tire structures.
Engineers say this prototype was capable of astonishing performance thanks to its experimental tires . During secret tests at the Ladoux circuit near Clermont-Ferrand, the SM Proto reached impressive top speeds while maintaining exemplary road holding. These tests, conducted in the greatest secrecy, allowed Michelin to develop the technologies that would later equip racing cars and production vehicles.
A tasty anecdote reports that a motoring journalist of the time, having had the opportunity to briefly test this prototype, declared that "this car did not roll, it glided on the asphalt like a skate on ice." This unique sensation was due to the special properties of the experimental tires, which offered unparalleled grip and ride comfort for the time.
The fate of this prototype remains a mystery. Some claim it was dismantled after testing, while others claim it still lies dormant in Michelin's secret archives. This aura of mystery contributes to the fascination this SM Proto still holds for collectors and French car enthusiasts.
