The famous and renowned coachbuilder Bertone was tasked by Alfa Romeo to build an aerodynamic experiment to measure the effects of streamlining on a car's performance. Scaglione was tasked with aiding in the creation of the design. The vehicle was dubbed the B.A.T. 5, representing 'Berlinetta Aerodinamica Tecnica.' 'Berlinetta' means 'small sedan' or, more precisely, 'coupe.' The design featured rear fenders and curved fins, truly a unique design. It was built upon an Alfa Romeo 1900 chassis.
The B.A.T. 7 was created a few years later and was again an experiment in aerodynamics. The B.A.T. 7 was even more radical in design and was adorned with very large curved tailfins.
The final B.A.T. Concept, the B.A.T. 9, was completed in 1955. It continued the experimentation with aerodynamics but was not as exaggerated as the prior models. The body styling took into account future production requirements and is arguably the most attractive of the B.A.T. automobiles.
Today, all three B.A.T. Concept Cars belong to Cars International Ltd., a specialty dealer located in Canary Wharf, London, UK.
Another prototype vehicle, the Giulietta Sprint Speciale, was introduced to the public at the 1957 Turin Motor Show and later went into limited production until mid-1959. The vehicle was based on the B.A.T. cars and built by Franco Scaglitone, Bertone's chief designer.
Alfa Romeo provided a five-speed gearbox and a powerful four-cylinder engine that produced more than 90 horsepower, good enough to propel the car to a top speed of 125 mph. The performance and handling aspects were phenomenal. The bodywork was steel with an alloy hood and trunk lid. The interior was elegant, comfortable, and functional. There was adequate space for luggage.
