A 1967 Camaro RS/SS convertible Indy Pace Car was used to pace the Langhorne 100 United States Auto Club (USAC) National Championship Trail (Indycar) event held at Langhorne Speedway in Langhorne, Pennsylvania on Sunday, June 18, 1967. This was the fifth race of the championship and the second race following the Indianapolis 500. The track was a one mile oval and 100 laps were run. Lloyd Ruby won the race in his Lotus/Ford.
You can see the Camaro on the right side of these pictures. There is a driver sitting in the car waiting to be called upon during a caution period. Notice that the date of this event is the same day as the June Sprints held at Road America that I previously posted pictures for. As a result, the Camaro used here at Langhorne Speedway could not possibly have been the same one used at Road America. While the close-up isn't conclusive, unlike the Camaro at Road America, this car appears to still have the "51st Annual Indianapolis 500 Mile Race May 30, 1967" at the bottom of the door. I originally thought it might be the same car that was used to actually pace the 1967 Indianapolis 500 but this car also appears to have the passenger side sun visor which was replaced on the Camaro that paced the Indianapolis 500 with a grab handle. The Langhorne Speedway pace car could be another one of the cars used in Indianapolis during the month of May. Like most, but not all of the Indy Pace Cars, this one has the Rally Wheels.
