Why it matters
The 1100 S was a compact sports berlinetta that Fiat added to its 1100 range in 1947, with a body drawn from the pre-war 508 C Mille Miglia and an uprated engine. It gave Fiat strong results in the early post-war Mille Miglia and its three-part grille became the model's hallmark.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Dante Giacosa designed the car at the end of the Second World War, taking inspiration from the pre-war 508 C Mille Miglia. The body was aerodynamic, had no bumpers and had skirts over the rear wheels, with a three-part grille of horizontal and vertical chrome bars.
At the 1947 Mille Miglia four 1100 S cars finished fifth, sixth, seventh and ninth overall. In 1948 the Apruzzi brothers took third place, with three more Fiat berlinettas in the top fifteen. Fiat states that 401 cars were built from 1947 to 1950 and that, because many were used hard in racing, very few survive. One car belongs to the Heritage Collection and is shown at the Fiat Historic Centre in Turin.
