Suspension was, as on other Alfa Romeos of the time, by double wishbones at the front and solid axle linked to the chassis by an upper triangle and two lower longitudinal reaction arms. The transmission was 4-speed gearbox with synchronised forwards speeds and a multi plate dry clutch. So configured, fed by two twin-choke sidedraught carburettors, the engine produced 158 PS (116 kW 156 hp) at 6,500 rpm. While the 1900s 88 mm stroke was retained, cylinder bore had grown from 82.55 mm to 85 mm, bringing total displacement to 1,997.4 cubic centimetres compression ratio was raised to 8.73:1. As on the 1900, the engine was an inline-four with double chain-driven overhead camshafts, but used an aluminium block and inserted sleeves instead of the 1900s cast iron one. īuilt around an all-new tubular space frame, the Disco Volante used lightened components from the Alfa Romeo 1900. Studied to achieve a low drag coefficient even in crosswinds, the body featured a lenticular cross-section both viewed from the front and from the side the underbody was faired-in.Īccording to some the design of the Jaguar E-Type has some design cues similar to the Disco Volante. Its fully enveloping aerodynamic bodywork was developed and built together with Carrozzeria Touring, and wind tunnel tested. The 1900 C52 was originally developed in 1952 to take part to Sport category races.
Four of the five cars built in total survive today.įront view of the 1952 Disco Volante Spider, highlighting the lenticular cross-section of the body. Two more examples were built fitted with a six-cylinder 3.5-litre engine from the Alfa Romeo 6C 3000 CM racing car. Three spiders were made in 1952, with a 2-litre all-alloy four-cylinder engine a year later one was modified into a coupé, and another one into a more conventional-looking spider. The car was distinguished by streamlined, wind tunnel tested bodywork.
