Carlo Abarth, motorsport director of Piero Dusio’s Cisitalia S.p.A., took over the foundering of that firm’s Italian assets when Dusio decamped to Argentina in 1949. Abarth & Co. thus came into being, and its proprietor took the leftover Cisitalia cars, renamed them Abarth, and set off racing with such drivers as Tazio Nuvolari, Franco Cortese, and Piero Taruffi.
Starting with Fiat’s new 600, Abarth bored and stroked its 633–cubic centimetre engine to 747 cubic centimetres. The camshaft and flywheel were modified, and a larger carburettor was fitted, with the result being nearly 40 brake horsepower and a top speed of more than 80 mph. The Abarth 750 GT debuted in 1956. Fiat delivered the standard-body 600s to Abarth in incomplete form, with the purpose of simplifying the performance modifications.
Soon, the highly respected Carrozzeria Zagato in Milan took on production of Abarth’s coupé bodies. The coachbuilder’s sketches for the body had a roof so low that there was scant headroom for a person of normal stature, so twin bulges were placed into the roof contour. The result was immediately nicknamed ‘Double Bubble’, a nickname that has become synonymous with Zagato’s sporting coupés and continues to influence their design to this day.
The example offered here, chassis 565298, was built in 1958 and is believed to have spent much of its life in the USA. It had resided in New York where it was part of a collection containing some very important pre- and post-war competition cars. The 750 GT then moved through Arizona and Connecticut before the UK-based consignor acquired it and returned the car to Europe.
For many, the Fiat-Abarth 750 GT ‘Double Bubble’ is as recognisable as any of the world’s most collectable cars; here is an opportunity to make such a car exactly as you wish!
