History of the Siata 208S
Siata presented the 208S in 1952. Its body was a lightweight aluminium spider designed by Giovanni Michelotti and built by the Turinese coachbuilder Rocco Motto, and in Siata’s range the open car was the roadster counterpart of the 208 CS coupé. The company built only 35 examples of the 208S, two of them to Bertone designs rather than the standard Michelotti shape.

The car became known outside Italy after the actor and racing driver Steve McQueen bought one. His car, chassis BS523, was sold to him in the mid-1950s by Ernie McAfee, Siata’s importer in Los Angeles. McQueen is said to have replaced the Siata badges with Ferrari emblems and called the car his “Little Ferrari”, a name that has stuck to the model.
Mechanically the 208S was derived in part from the Fiat 8V. It used Fiat’s all-alloy Tipo 104 engine, a 70-degree V8 of two litres, which developed 125 hp (93 kW) and gave the little spider a top speed of 200 km/h (124 mph). Contemporary testing by Road & Track recorded a 0–60 mph time of 12.4 seconds and a quarter-mile time of 17.8 seconds.
The 208S wore all-aluminium bodywork and had four-wheel independent suspension, an advanced arrangement for a small Italian sports car of the early 1950s. The combination of the light body and the Fiat-derived V8 made it a quick car for its size, and the McQueen connection has made chassis BS523 the best known of the 35 examples.
