Yes...but the original idea had some special features that went lost in the realization of Dubonnet's car.
From Daniele Neri's interview with Luigi Fittipaldi:
(Automatic Translation)
'It was Ernesto Maserati that a
day, praising the genius of Eng.
Coda, told me that a rich
French Industrial, pilot
and car manufacturer,
Andre Dubonnet, has built in
1936 an aerodynamic car
inspired by the project that Eng.
Coda had patented in 1935.
I later learned that Eng. Coda was very disappointed
by that, because he had
proposed his avant-garde project
to Citroen during his stay in Paris and then
back to Milan, again to Citroen
after he patented his idea in 1935.
He did not have the support for the realization
and a prototype for more
developments of the project. But Dubonnet's aerodynamic vehicle,
called "Dauphin"
(Delfino), lacked the support of
study on the aerodynamics of the body
and cage "carrier" thanks to which Coda removed the
spars, and many other solutions
absolutely avant-garde.'
