Can Am Series

The Canadian-American Challenge Cup, or Can Am Series, was a prototype-based racing series established by the Sports Car Club of America in 1966 out of the remnants of the United States Road Racing Championship. The concept of the series was that it was unregulated, allowing for more heated competition between teams. The series lasted until 1974, likely caused by the Oil Crisis of 1973. The series was revived a few years later based on Formula 5000, but was much less successful. When the USRRC was revived decades later the prototype category was called Can Am, but the series was unsuccessful.
