McLaren first contested the United States Auto Club's (USAC) Indianapolis 500 race in 1970, encouraged by their tyre supplier Goodyear, which wanted to break competitor Firestone's stranglehold on the event. With the M15 car, Bruce, Chris Amon, and Denny Hulme entered, but after Amon withdrew and Hulme was severely burned on the hands in an incident in practice, Peter Revson and Carl Williams took their places in the race to retire and finish seventh, respectively. The team also contested some of the more prestigious races in the USAC championship that year, as they would do in subsequent years. For 1971 they had a new car, the M16, which driver Mark Donohue said "...obsoleted every other car on track..." At that year's Indianapolis 500, Revson qualified on pole and finished second, whilst in 1972, Donohue won in privateer Team Penske's M16B. The 1973 event had Johnny Rutherford join the team; he qualified on pole, but finished ninth, Revson crashed out. McLaren won their first Indianapolis 500 in 1974 with Rutherford. The McLaren and Rutherford combination was second in 1975 and won again in 1976. Developments of the M16 had been used throughout this period until the new M24 car was introduced in 1977. The team did not reproduce their recent success at Indianapolis in 1977, 1978, or 1979, and although they continued to win other USAC races, by the end of 1979, they decided to end their involvement.
