The Vallelunga relied on upon a roadster arranged through Carozzeria Fissore and named after the Autodromo di Vallelunga initially showed up as a thought auto at the Turin Motor Show in 1963. De Tomaso had wanted to offer the framework of the thought to another association, however when there were no takers had the auto made by Ghia.
The engine was a 1.5 L straight-4 Kent engine from the Ford Cortina with 104 hp (78 kW) at 6200 rpm. A Volkswagen Beetle transaxle, fitted with Hewland gearsets, was used. The body was a crushed steel spine with a tubular subframe at the back. Suspension was twofold wishbone and twist springs at all four corners with front and back threatening to move bars and with uprights sourced from Triumph. The little auto weighed 726 kg (1,600 lb) with a fiberglass body and various exhausted aluminum parts. Brakes were circle all around.
The casing was not torsionally stable for engines with higher torque, an issue exacerbated by softened welding up the Italian-made spine. Drivetrain vibration was a consistent issue for those cars. 50 era cars were worked, close by three aluminum-bodied models and five aluminum-bodied hustling cars, bringing the total to 58. The Vallelunga was supplanted by the Mangusta. The Mangusta used the thought of the Vallelunga skeleton, out and out re-intended to take a Ford 302 engine, all packaged with a body by Giorgetto Giugiaro.
The minor Vallelunga was worked around a pressed steel spine undercarriage. Not in any manner such as Lotus’ relative design, which bolstered the engine in Y-formed developments of the case, the Vallelunga’s spine completed before the engine. Maybe, the engine and the back suspension was mounted in an alternate tubular steel subframe. At the front a subframe was mounted to support the radiator.
