The design of C prototypes starts in 1953 under the direction of André Lefebvre. This program is motivated by some strong principles inspired by aeronautics: lightness and compactness with the weight well forward; fuel-efficient and optimal aerodynamics thanks to an oval "water droplet" profile and squeezed rear track width.
The most promising prototype is presented in 1956: the C10 of unique style – and curves. It weighs in at just 382 kg and boasts a Cd of 0.258. The small 425 cc engine of the 2CV AZ delivers a top speed of 68 mph.
And the story does not stop there. Although this little gem could not match the promises of the future Ami 6 then under development, its style prefigures that of the first Citroën minivans and offers a first glimpse the rounded lines of the future Xsara Picasso.
