Rufus Parnell "Parnelli" Jones is an American former professional racing driver and racing team owner. He is notable for his accomplishments while competing in the Indianapolis 500 and the Baja 1000 desert race, and the Trans-Am Championship series. In 1962, he became the first driver to qualify over 150 mph. He won the race in 1963, then famously broke down while leading the 1967 race with three laps to go in a turbine car. During his career as an owner, he won the Indy 500 in 1970–1971 with driver Al Unser.

The 51st International 500 Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana, over two days, Tuesday May 30 and Wednesday May 31, 1967. The race was dominated by Parnelli Jones in the radically new, four-wheel drive STP-Paxton Turbocar gas turbine entered by prolific car owner Andy Granatelli. With three laps to go, however, Jones coasted to a stop when a $6 transmission bearing failed. A. J. Foyt assumed the lead, and weaved his way through a pileup on the final lap, to win his third Indy 500 victory.
