Jo Siffert was the first to take the 917 to Can-Am championship. The car he used in 1969, was the 917 PA Spyder. Although he participated in one Can-Am race in 1970 with a 917 K, that season he skipped. He was back from mid-season 1971 and now with the 917/10. Only two 917/10 were created in 1971. The chassis 001 was used for testing and the 002 by Siffert. He took part in six races out of ten, managed podium finishes three times and scored 4th in the season, like in 1969.
