With a height of only 147 cm (58 in.), the steel and aluminum body had no running boards, fenders or door handles. Instead, the doors could be opened using buttons located on the outside and on the instrument panel. To match the advanced design, Heinz chose the most advanced chassis available in the United States at that time, the Cord 810. The V8 engine-equipped Cord also featured front wheel drive and an electrically operated four-speed gearbox, as well as a fully independent suspension and adjustable shock absorbers. To accommodate the large body, various changes were carried through on the chassis. The car's lower frame was made of chromoly steel and the upper frame was constructed of electrically welded aviation steel tubing. Power for the 2-ton / 4500 lb. (2000 kg) Phantom Corsair came from a modified Cord 810 Lycoming 8-cylinder unit, supercharged to produce about 190 hp.
