ATS (Automobili Turismo e Sport) is an Italian automotive constructor. It once had a racing team that operated between 1963 and 1965. Construction of a Formula One car, the Tipo 100, began in mid-1962 on a farm near Bologna, with the car being unveiled in that city in December 1962. The Tipo 100 had a pencil thin body, and was powered by a V8 1,494cc engine, which featured fuel injection and double-overhead camshafts. The transmission was a 6-speed Colotti gearbox. Suspension consisted of rocker arms with inboard coils for the front, and double wishbones with coils for the rear, while disc brakes were mounted inboard. Total weight was just over 1,000 pounds. The cars were to be driven by Phil Hill and Giancarlo Baghetti, who had both left Ferrari after a disappointing 1962 season.

The cars made their first appearance, at the Belgian Grand Prix. Spectators, officials and fellow competitors were shocked by the Tipo 100's appearance. After looking so fantastic at the public unveiling back in Bologna, they now had rumpled body panels, pock marks and were poorly painted. The cars were oily and greasy, the body panels were ill-fitting. Due to the reinforcing tubes being over the top of the engine, they had to be sawed apart for an engine change, and then welded back into place. A new higher engine cover had been hurriedly fabricated to hide the tubes.

Both cars retired, as was the case with in the Dutch Grand Prix. The team did not attend the French, British and German races. The Tipo 100 returned for the Italian Grand Prix, and both cars started and finished, although a long way down the field – Hill 11th and Baghetti 15th. 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, which marked the end of A.T.S as a Formula 1 team.
