Andre Dubonnet was an accomplished amateur racing driver and inventor. In 1927 working with engineer Antoine-Marie Chedru, Andre patented a four-wheel independent "hyperflex" suspension system that he promoted as having the "suppleness of a cat". This system was used in modified forms by GM, Fiat, Alfa Romeo. and Delahaye.
Dubonnet purchased a modified a Hispano-Suiza chassis, designed by Jean Andreau and which was displayed at the 1932 Paris Salon, to display his automotive designs. Dubonnet employed a renowned coachbuilder Jacques Saoutchik to create this revolutionary body, Dubonnet's fifth prototype attempt in 1938. He named the finished car "Xenia" after his late-wife.
