The bodywork was commissioned to Nieuport, an aircraft manufacturer. Despite the luxurious appearance it was a race car. It was sixth on the Targa Florio and the fifth on the Florio Cup. This luxury car was stripped naked, with only the chassis and engine. All J12s were unique. The engine was V12 at 60 degrees. The engine block was machined from a 313 kg casting block. The crankshaft rotated on seven bearings. Each cylinder had two valves operated by rockers from a central camshaft. According to the designer, Mark Birkit, this solution (apparently less sophisticated than the camshafts in the cilinde head) was chosen as less noisy. The Phantom Corsair was built as a two-door [[Sedan (car) | sedan]) for six passengers. A futuristic body was mounted on a Cord 810 chassis. This car was the result of a collaboration between young Rust Heinz (heir to the food industry tycoons Heinz) and the signing of bodywork Bohman & Schwartz. The mechanics of choice were the Cord 810 with a Lycoming V8 engine and front-wheel drive. Manufacturing intentions were void of the death of promoter Rust Heinz in a car accident. American James Glickenhaus commissioned Pininfarina to create a special P3 racing body. The mechanical base was the Ferrari Enzo. The result would be designated with the reference Ferrari P4 / 5 by Pininfarina, authorized by the Ferrari house.

Two camshafts (4 trees in total) driven by a cascade of toothed wheels. It offered a power of 78 hp (58 kW) at 12000 rpm and weighed 45 kg. It was designed by the engineer Giulio Carcano. The motorcycle broke the speed record with a speed of 280 km / h, a mark of would remain for 20 years.

Apart from the initial prototype, ten units were built with noticeable differences. Specially configured military twin-engine aircraft.
