Background
Robet Opron’s second interview at Citroen’s Bureau d'Études in 1962 didn’t go awfully well…..or so he thought. He met with Flaminio Bertoni, Citroen’s then chief designer and creator of the motoring icons that were the 2CV and DS. Bertoni asked to see Opron’s portfolio and shortly after thumbing through the drawings he "threw them on the floor, poking them with his cane and stated that he did not think much of them." To his surprise, then, Opron received a letter of engagement from Citroen two weeks later. Opron and Bertoni’s relationship was short with the former succeeding the latter upon his death in 1964.
Opron’s projects included the 1970 GS and the sublime Maserati engined SM. His favourite project whilst at Citroen, however, was “Projet L.” The Projet L team was charged with the far from trivial task of replacing the esteemed and beloved DS. Determined not to undercook the croissant, Opron was committed to a technology led design from the get-go. With the Citroen wind tunnel wound up to “storm force,” Opron created one of the slipperiest saloon designs ever created to that point. The car would even be christened the “CX,” the widely used acronym for drag coefficient. In fact, the car achieved a highly creditable coefficient of 0.36 compared to a norm for its competitors of above 0.4.
In true Citroen style, there was really nothing conventional about the CX. The car had even been designed around Citroen’s innovative but fatally flawed, three blade, Comotor rotary engine. Due to economy and reliability concerns, the Comotor was shelved in 1974, the year of the CX’s launch at the Paris Motor Show. The Comotor’s demise also contributed to Citroen’s bankruptcy of the same year with the more financially prudent Peugeot taking up the reins of the company.
Despite all these significant headwinds, the CX was ultimately a huge success offering the world what it is so often lacking – a viable and different left-of-field option rather than another “me too” automotive clone. There was no “me too” with the CX. Innovations included the unique hydropneumatic suspension of course (good enough to be adopted under license by Rolls Royce for the Silver Shadow and Bentley T), but also the feather light DIRAVI powered steering, stalkless controls and delightfully quirky, fish-eye barrel type instrumentation.
