The Fiat-Abarth 750 GT Zagato made its debut at the 1956 Geneva Motor Show. Austrian Carlo Abarth (aka Karl Abarth), who was an importer and distributor of Porsche automobiles, and he had worked with Ferry Porsche in the years after the Second World War.
Carlo Abarth had located in Turin, Italy and had adopted the Italian penchant for surprisingly fast cars. He had the imagination to understand the speed potential of the utilitarian Fiat 600 and set about re-creating it into something that exuded adrenaline pumping excitement.
Abarth created high performance versions of the Fiat 600 which used the original bodywork and others fitted with custom GT sports car bodywork by Bertone and Zagato.
The first of the Zagato alloy bodied Fiat-Abarth 750 cars was shown at the 1955 Turin Motor Show. The car featured the trademark Zagato “double-bubble” roof atop the aerodynamic lightweight body.
That car was fitted with a 747cc SOHC inline four cylinder engine and it was upgraded in 1958 to a DOHC engine of the same capacity producing 57bhp, which was well able to propel the diminutive 750 GT Zagato’s 1179lb (535kg) weight up to white knuckle velocities.
Some of these fabulous little cars were used as road cars and some were stripped down and used on the race track.
One of these racing cars is for sale on Bring a Trailer at time of publication.
This car was converted for racing in the 1980’s and was campaigned at such circuits as Laguna Seca, Thunderhill, and Sonoma into the early 2000s.
