In 1955, President Coty of France commissioned Franay to design and build a presidential car using the mechanical elements of the recently launched 15-Six H. Unfortunately, the car overheated when moving at walking pace during ceremonial parades and broke down during the 1957 state visit of Queen Elizabeth II of the United Kingdom. The car was eventually modified in the light of this deeply embarassing spectacle and was used by Coty's successor, General Charles de Gaulle.
