Ted Field's hands-on involvement in motorsport culminated in one of the most ill-fated technical gambits of early 1980s Indy racing. In 1980 Field financed construction of an Interscope chassis designed by Roman Slobodynskyj that was intended to carry a turbocharged six‑cylinder Porsche engine—the idea being to translate the 935 sports‑car powerplant success into Indianapolis 500 competitiveness. A regulatory showdown with USAC over permitted turbo boost killed that turbo program, forcing the car to be refitted with a conventional Ford Cosworth DFX. Running Danny Ongais in the 1981 500, the car briefly led the race before Ongais suffered a massive crash that left him critically injured; a comeback effort in 1982 ended with another accident. The sequence effectively ended the bold Interscope chassis project, derailed Ongais's momentum and left a permanent, dangerous footnote on Field's early racing ventures—an expensive, high‑profile reminder of how engineering ambition, regulatory politics, and the raw risk of open‑wheel racing could conspire to catastrophic effect.
