This amazing device was built during a very brief trend for motorised catamarans in the fifties. Enrico Nardi, whose name is still very much in the public consciousness, due to the continuing success of his steering wheels, had been building special low volume racing cars since 1947.
His client , Dr Damonte, had been successful at Le Mans in 1952 and 53 (see description of his OSCA on this gallery) and dreamt up something a lot more radical for 1955. Carlo Mollino designed the body, built by Carrozzeria Motto, engine was by Giannini (735cc), upon Nardi's bizarre chassis.
The "Bisiluro" (Italian for twin torpedo) was very slow in practice, and after running at the end of the field for two hours, it was literally "blown into the weeds" by the vortex of a passing D type Jaguar, fortunately without injury to the good doctor, who quickly packed his bags, never to return.
