ATS (Automobili Turismo e Sport) company was formed by Carlo Chiti and Giotto Bizzarrini in 1962 to build road and racing cars which will be able compete with Ferrari. Scuderia Serenissima owner Count Giovanni Volpi provided a sponsorship for road-going sports car and Formula 1 racer. The sports car, ATS 2500 GT, powered by mid-mounted 2.5 L V8 motor engineered by Chiti, was presented in April 1963. The Formula 1 vehicle, Tipo 100 powered by a V8 1,494cc engine, was developed simultaneously with the sports car. Tipo 100 featured fuel injection and double-overhead camshafts, had a pencil thin body, and was very light – just over 450 kg. The car to be driven by Phil Hill and Giancarlo Baghetti, who had both left Ferrari after a disappointing 1962 season. Car was not ready in the beginning of the 1963 season, ant the ATS entries were withdrawn from several non-championship races and from Moncao Grand Prix. Tipo 100 finally appeared in June at the Belgian Grand Prix in Spa-Francorchamps. Both cars, hastily assembled, retired both in Belgium and at the next race in Holland. Then the team took a break to tune the car, and at the home Italian Grand Prix, Hill and Baghetti were finally able to reach the finish line, but only in 11 and 15 places. That was the only race where an ATS was classified as a finisher, with both cars retiring in the United States Grand Prix and Mexican Grand Prix. For the 1964 season ATS Tipo 100 was sold to Derrington-Francis team, the car was modified and appeared in the 1964 Italian Grand Prix as Derrington-Francis, driven by Mário de Araújo Cabral.
