ATS (Automobili Turismo e Sport) is an Italian automotive constructor. It once had a racing team that operated between 1963 and 1965, formed after the famous "Palace Revolution" at Ferrari. Production history The company was formed by Carlo Chiti and Giotto Bizzarrini, among others – intending for it to be a direct competitor to Ferrari both on the race track and on the street. Chiti and Bizzarrini built, with sponsorship from the Scuderia Serenissima's Count Giovanni Volpi, a road-going sports car and a Formula One racing car. It was presented in April 1963 at the Geneva Motor Show. The sports car was the ATS 2500 GT, a small coupé developed by Chiti and Bizzarrini with a Franco Scaglione-designed bodywork built by Allemano. The engine was a mid-mounted 2.5 L V8 engineered by Chiti, capable of achieving 245 hp (180 kW) and accelerating to 257 km/h (160 mph). Only 12 cars were reportedly built, and few exist today. Apart from being the second mid-engine sports cars (the René-Bonnet / Matra Djet was presented five months earlier at the Salon de l'Autombile in Paris, France), the 2500 GT never gained fame or popularity, but its 90 degree DOHC V8 with a flatplane crankshaft was later developed into Alfa Romeo Tipo 33 engine in 2 L, 2.5 L and 3 L formats by Carlo Chiti at Autodelta. Racing history 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. Testing took place at Monza, but this was slow and tedious, as when something broke, the car had to be taken back to Bologna for repairs, and then taken back to Monza for further testing. One of the major problems was chassis flexing, which was fixed by the unusual method of reinforcing tubes being welded over the top of the engine. The
