The first monococque had to be aborted due to a change in regulations and the second tub was known as PC2. However, record books show the car driven by Migault and others as PC1. The intent was to compete in the Formula One World Championship in 1972, but a lack of financial and technical resources meant that the car only managed to start in one championship race, the 1972 Austrian Grand Prix, with French driver François Migault at the wheel. Following the Austrian race, the car competed in a handful of non-championship races before being converted to meet Formula 5000 specifications for the 1973 season.
