This very unusual six-passenger coupe was designed by Rust Heinz, a member of the H. J. Heinz family. The design was a joint effort of Heinz and Maurice Schwartz of the custom body firm Bohman & Schwartz in Pasadena, California. Heinz' creation, costing approximately $24,000 in 1938, featured aerodynamic engineering, front-wheel-drive, electric gear shift, four speeds forward and a Cord V-8 Lycoming engine which was modified by Andy Granatelli.

Built on a modified Cord 810 chassis, the car's lower frame was made of chrome molybdenum steel and the upper frame was constructed of electrically welded aviation steel tubing. The allow steel and aluminum body had no running boards, fenders or door handles. The doors were opened at the touch of buttons located on the outside and on the instrument panel. The interior was padded throughout with cork and rubber for safety, sound proofing, and insulation.

In addition o the normal instruments found in a stock Cord panel there were oil temperature, manifold vacuum and fuel economizer gauges, battery charge level indicator, altimeter, barometer and compass. Four persons sat across the front seat and two in the back seat, facing the rear. Approximate top speed was 115 mph. Heinz planned to put the Phantom Corsair into limited production at an estimated selling price of $12,500. His death, however, shortly after the car was completed, ended those plans.
