Created by Roger Penske, Les Richter, and Mike Phelps, the International Race of Champions (IROC) was a North American all-star racing series with well-known drivers from a range of motorsports disciplines, including Indy car, NASCAR, and Formula 1. For the inaugural 1973/74 season, the drivers raced identically prepared Porsche 911 RSRs, of which 15 were built—12 for the drivers and three reserve cars. The RSR was based on the RS 3.0 road car and had a wide body and a fiberglass “whale tail.” This vehicle was driven by New Zealander Denny Hulme, who made a name for himself in F1 and Can-Am racing. Hulme finished 8th in the IROC series that year.
