Salon de l'automobile de Turin
Alfa Romeo contacted Giuseppe "Nuccio" Bertone of the Bertone design house and commissioned three concept vehicles to research the effects of drag on a vehicle. The idea was to create vehicles with the lowest possible drag coefficient. All the cars featured large rear bumpers and curved fins. They were built upon the Alfa Romeo 1900 chassis. Each of the three cars was presented at the Turin Auto Show, in 1953, 1954 and 1955 respectively.
