In the early 1960s, Enzo Ferrari's wife, Laura Garello, had been included on the company staff and due to her difficult nature, like her husband, she was at odds with many of the company's technicians and managers.
The original Ferrari 250 GTO on which Chiti and Bizzarrini were working
This resulted in the mass dismissal of many exceptional personalities including Carlo Chiti, Romolo Tavoni and Giotto Bizzarrini and the latter decided to compete with Drake in 1962, founding the Automobili Turismo e Sport company in Bologna.
ATS 2500 GT
Considering the model they were developing, namely the Ferrari 250 GTO, it had remained incomplete and it was difficult for anyone to complete it effectively the three founders decided to build a new sports car that would constitute a valid alternative.
Thus the 2500 GT was born based on a tubular frame covered by a steel bodywork designed by Allemano in which a V8 2.5 16V engine was inserted, managed by a five-speed manual gearbox and combined with rear-wheel drive.
Able to develop 210 hp with 250 Nm of torque, the engine allowed the vehicle to reach a top speed of 240 km / h with acceleration from 0 to 100 km / h in 5.7 seconds.
ATS 2500 GTS
Simultaneously with the GT was also built the GTS variant which differed for the lightest aluminum body and the 245 hp power developed by the propulsion unit.
Built until 1965 in a dozen units, both the GT and the GTS did not have the desired success due to the continuous failures to which they were subjected and the company had to close due to lack of productivity.
Adding insult to injury, the Ferrari 250 GTO became the absolute masterpiece of Scuderia Ferrari thanks to the intervention of Mauro Forghieri and Sergio Scaglietti who managed to complete and improve it.
