In 1956, Abarth had already built up an extensive reputation as a premier tuner of Fiat engines and was branching out into many classes of motor sport. The production 750 GT first appeared at the 1956 Geneva Motor Show. Series production began in 1957. The final design included twin bumperettes upfront, Zagato’s double bubble roof and twin intakes on the rear engine cover. Five of these cars finished the Mille Miglia in 1957, of which Alfonso Thiele won the 750cc class.
