The PR01 was used in every race of the season. At the 1st round of the season in Brazil, Belmondo failed to qualify, but Gachot managed to qualify. Unfortunately, he crashed out of the race. They both failed to qualify for the next round in Aida, but Gachot qualified for Imola only to retire with an oil-pressure problem. Belmondo and Gachot qualified for the next two rounds of the world championship. This would be the only two rounds of the season Belmondo would qualify for. Gachot qualified for the 6th round in Canada, only to be hit by an oil-pressure problem again. This would be the final time any of the two cars qualified in the season as Gachot and Belmondo did not qualify for the remaining ten rounds of the season. The team even considered withdrawing from the championship in order to work on their PR02 chassis, however if this happened, they would have had to pay a substantial fine.
