Carl Abarth bored out the 633cc 4-cylinder engine to 747cc and tuned it to 42bhp for the Fiat Abarth 750. A special model was then built with a Zagato body as the Fiat Abarth 750 GTZ which was built on the Fiat 600 platform. The 750 GTZ was launched at the 1955 Salon di Torino. The GTZ had a top speed of 90mph and 600 were sold from 1959. After disagreements with Elio Zagato, Carl Abarth developed the 750 GTZ with a twin cam engine and the body evolved by Sibona and Basono into the Bialbero 700 and 1000 models.
