1963 ATS 2500 GT
In 1964 this svelte coupe was manufactured from ex-Ferrari personnel to compete at the top the market. It used a bespoke V8 mounted behind the passengers with a high level of appointments.
Automobili Turismo e Sport SpA (SPA) was an Italian company with engineering support from Carlo Chiti and Giotto Bizzarrini. The company took full advantage of ther ex-Ferrari expertise and financing by Count Giovanni Volpi. Later when Bizzarrini and Volpi left, Chiti finished the design with his own V8.
Central to the 2500 GT was a bespoke 2.5-liter engine that not far off a Ferrari unit. It was an all-aluminum 90º V8 that could produce from 210 to 250 horsepower using Weber twin-choke carburettors. The 9000 rpm redline took full advantage of the Abarth custom exhaust and five-speed Colotti gearbox. A mechanical fuel injection system was offered as an option.
Holding the car together was a tubular steel spaceframe which sported a double-wishbone suspension bot front and rear.
Inside, the 2500 GT received a full leather treatment with a Nardi wooden steering wheel and electric power windows. Power brakes were also standard.
Bertone stylist Franco Scaglione was responsible for designing the exterior of the car. He penned a sleek fastback with an integrated front bumper and a rear hatch for access to the V8 engine. The standard GT model featured a steel body while the GTS was equipped with an all-aluminum body for events like the Targa Florio.
The first ATS appeared at the 1963 Geneva Motor Show as one of the first mid-engine sports cars to enter the market. The showcar was lavishly trimmed for touring unlike the racecars that followed it.
Ultimately, ATS only completed eight cars with some of the final cars using 3.0-liter version of the engines. As many as four unused chassis were manufactured when the company was liquidated.
