The 1972 917/10 was similar in its design to the 908/03, but, of course, had the 12-cylinder engine instead of the 3-litre flat-8. The 917/10-72 was first seen at the Interserie Nürburgring race on April 3. It was the chassis 004 car of Leo Kinnunen and Keimola Racing Team AAW. Kinnunen scored 4th in the first race, but would win the championship by the end of the season. The second Interserie race was at Monza on May 1st and that race was won by chassis 917/10-002 and Willy Kauhsen.
