The Bandini 1100 siluro is a racing car model produced from 1947 to 1949 by Bandini Automobili in Forlì, Italy.
This type is the first Bandini born expressly to race. The style and forms were created for pure speed, performance and lightness. The name Siluro (English: torpedo) was chosen to indicate the aerodynamic penetration and be a good omen for the races. Initially, to reduce weight and quicken repairs, they were not even painted.
Bandini first participated in competitions in 1949. These included Italian competitions such as the "Giro dell'Umbria" (Lap of Umbria), the "Pescara Circuit", and the "Senigallia Circuit", as well as more important, internationally-recognized events, such as Mille Miglia. It mise on display, led by Richard W. Gent to Queen Catherine Cup at Watkins Glen in front of two hundred thousand spectators opening to the Italians cars the road to fame in the USA.
The body[]
The body had two seats and was made of aluminium. It was built by Bandini, at the headquarters of Via Cesare Battisti in Forlì. Small cycle fenders (or cycle wings) were fitted, so the body adhered to the frame assuming forms without imposing its own. The result is a synergistic combination of technology and aerodynamically efficient torpedo styling, as well as elements from the animal kingdom. Ilario Bandini, from the end of the observer, loved to reiterate that nature had solved very well functional problems that man is initiated only to face. Thus the muzzle, designed to direct as much air to the engine without overloading the front section, has the characteristics of enormous nostrils; lights are encased in it as the eyes of a fish, the heat is disposed of using louvers resembling the gills of a shark. In order to reduce weight as much as possible, the tail was very short and round and only the passenger had a door. Sometimes the bonnet reveals, with two bombature shaped flame, the use of a twin cam engine.
The chassis[]
The frame is a refinement of the 1100 sport, produced in parallel, which is the version to competition. The size and weight are reduced significantly. The height from the ground is 13 cm, while the bare chassis weighs only 25 kg (55 lb).
